Description

P37013NL00 / RR Title: Pot plant cultivation method and cultivation pots with hiding / nesting chambers on the underside include those designed as air bells. FIELD OF EXPERTISE The invention relates to a pot plant cultivation method, preferably in a greenhouse, whereby use is made of for the biological control of pests in potted plants predatory spiders. In addition, the invention relates to special breeding pots for use in such a method. STATE OF THE ART The function of growing pots in the cultivation of potted plants is multifaceted and important for the growth and development of the potted plants. Some important aspects are: - ensure that plant roots can develop properly; - providing good stability and support to these plant roots; - ensure good drainage after watering in order to remove excess water and thus to minimize the risk of root rot; and - ensure good air circulation around the plant roots. Thus, good growing pots can make a significant contribution to healthy growth and development of the potted plants by creating optimal growing conditions. Such growing pots comprise a profiled pot base with irrigation / drainage openings and one extending upwards from the bottom of the pot all around a central centerline extending rotationally symmetrical pot perimeter wall. The pot base and the pot perimeter walls together delimit an inner area for incorporating therein substrate and a potted plant planted in the substrate. The growing pots are usually made of plastic, and are then primarily manufactured by means of injection molding. For example, NL-1015373 shows a growing pot with a profiled pot bottom that in The center is executed with an upward-sloping truncated conical bottom section. around which a ring-shaped, flat section of the pot bottom extends. Both the ring-shaped flat pot bottom section as well as the sloping upward perimeter wall of the Upward-sloping truncated conical pot bottom section is provided with its own series drainage holes. NL-2008780 shows a growing pot with a stepped, conical, raised pot base. where on four levels of the stepped raised pot bottom as well as on the underside of the pot perimeter wall, a series of irrigation / drainage holes is provided. This large number of openings in the bottom of the pot ensures that the root ball can be sufficiently aerated, while also excess water can be properly drained. There is a trend towards the use of biological pesticides in the cultivation of potted plants to control pests and diseases, and thus to the use of chemical pesticides to reduce or render redundant. This is encouraged by stricter laws and regulations from governments to reduce the use of chemical pesticides. In addition, there is a growing consumer demand for organic and environmentally friendly products. cultivated plants. This has encouraged potted plant growers to switch to biological control methods to meet this demand. These biological Control methods are increasingly using predatory spiders to combat the pests. to fight. In many potted plant crops, for both garden and houseplants, such as potted gerberas, For potted hydrangeas, potted lilies, cyclamen, etc., an ebb & flow system is used for watering. flood system. To this end, the cultivation pots containing the still young potted plants are placed in large quantities placed side by side on ebb and flow cultivation tables or floors. The ebb and The flood tables are each provided with a raised edge, creating a flat water basin. arises. The ebb and flow cultivation floor, for example, is formed by a concrete floor with raised edges or a sturdy foil with a layer of porous rock that can be filled with water. The ebb and flow system is an irrigation technique in which water is periodically in the tray or is led onto the floor (high tide) and then drained again (low tide). All potted plants thus simultaneously receive the same amount of water from below, with as result efficient watering and oxygen supply to the roots of the potted plants and uniformly and vigorously growing potted plants. During flood, the cultivation pots containing the Potted plants placed in a layer of water a few centimeters deep for a while. The roots and the potting soil then get the opportunity to absorb sufficient water. During low tide, the water level drops. so that excess water can drain away from the growing pot and the moisture level in the growing pot does not become too high. The rise time, stand time, and drain time of ebb and flow can differ. for every type of potted plant, to ensure a vital, resilient potted plant with a strong developed root system. Disadvantageous in potted plant cultivation where use is made for biological pest control made of predatory spiders, and where an ebb and flow system is used for watering. flood system, is that during every tide large numbers of previously released predatory spiders can end up drowning. Especially those predatory spiders that take refuge under the 2 those who have sought growing pots will inevitably drown if the water level during the rising water (flood) rises. Nests containing eggs for offspring that the predatory spiders that have made their way to the undersides of the breeding pots will also be underwater come to stand, and therefore have a high chance of being irreparably damaged. and to perish. The death of large numbers of the predatory spiders as well as the loss of their chance of offspring, slows down the natural control of the pest to be controlled for an important part, and makes it necessary to regularly, in the worst case repeatedly after a number of tide cycles have taken place, new loads of the to release predatory spiders. This is labor-intensive, costly, and thereby increases the costs of cultivation. A similar disadvantage can also occur in potted plant cultivation where the watering on takes place in another manner, for example from above. Even then, as a result of the watering previously released predatory spiders may drown, or their nests can the bottoms of the growing pots become irreparably damaged. SHORT DESCRIPTION OF THE ULTIVLAND The present invention aims to at least eliminate the above-mentioned disadvantages. to partially overcome or to provide a usable alternative. In the In particular, the invention aims to provide a pot plant cultivation method that makes use of biological control with predatory spiders or other predatory agents whereby the released predatory spiders or introduced predators have a better chance of surviving and the population to let thrive. According to the present invention, this objective is achieved by a pot plant cultivation method, preferably in a greenhouse, using biological pest control is made of predatory spiders or adversaries in accordance with claim 1, as well as by a cultivation pot according to conclusion 5. The potted plant cultivation method includes the steps: . placing potted plants growing in cultivation pots on a cultivation surface; releasing the predatory spiders or adding them to the ones placed on the cultivation area growing pots; and . ensuring watering of the potted plants. The growing pots are equipped with irrigation / drainage holes on the underside. The bottoms of the growing pots have raised areas extending upwards. 3 According to the concept of invention, overhead spaces form beneath the raised sections. shelter / nesting chambers for the, situated freely elevated above the tee / tab in the bottoms of the pots, freely raised above the tee / tab. predatory spiders or aquiline spiders, which have elevated shelter / nest chambers as air bells are designed to be airtight upwards and laterally, and downwards to be open. Thus, according to the invention, are a pot plant cultivation method and to be used for that purpose provided breeding pots in which the released predatory spiders or related species have a better chance to survive and allow the population to thrive. Watering, both via ebb and flow systems as well as in other ways such as from above, need no longer lead to ruin with great benefit to lead from large numbers of predatory spiders or attackers. Tests have shown that the predatory spiders or adversaries, when they are not hunting, like to come and hide in the raised shelter / nesting chambers under the growing pots. Should watering then if these occur, then these elevated shelter / nesting chambers offer safe havens. where the predatory spiders or related species are completely safe, can continue to breathe and not can be washed away or will drown. Furthermore, tests have shown that the predatory spiders or adversaries also like to come and nest in the elevated area Shelter / nesting chambers under the cultivation pots to ensure offspring. The reason for this is that the configuration of the shelters as air bells according to the air bubble principle, there automatically ensures that the shelter / nesting chambers are relatively warm and humid places offer where the predatory spiders or adversaries like to spend time. Warm air that during cultivation ascends towards the shelter / nesting chambers, will hover there to an advantage. Moreover the shelter / nesting chambers will remain free from strong air currents and cold wind that is under the can be drafty through the growing pots. This, together with the elevated positioning at a distance, is quite above the relatively cold and possibly harsh growing surface, creates in the shelter / nesting chamber a pleasant warmth and a safe, draft-free environment where the predatory spiders or adversaries they will prefer to come and nest. The warmth will promote their activity and reproduction. Not being exposed to strong air currents and cold wind will help them to to avoid stress and dehydration. In addition, there are at least as many shelters / nesting chambers. available if there are breeding pots, so that large numbers of predatory spiders or other predators to be able to live separately from each other and not have to get in each other's way. Thus, the use of the specially designed growing pots during potted plant cultivation method according to the invention the population of predatory spiders or as Pest controllers are flourishing. This, in turn, leads to better results in biological control. control of pests that may occur during cultivation. In addition, the use helps continue making grow pots that drain well and promote air circulation, to prevent root rot or fungal diseases from occurring in potted plants. 4 The elevated shelter / nesting chambers are also well-suited for predatory spiders or to make spun threads there, either as a shelter for themselves (so-called wool houses'), either as fluffy little balls to lay eggs in for offspring (so-called egg cocoons or egg sacs). Creating the shelter / nesting chambers for non only the predatory spiders or adversaries but also their webs is therefore a very good proven to be a way to improve biodiversity and the effectiveness of biological to enhance control strategies. The wool houses in the shelter / nesting chambers under the cultivation pots form crucial habitats for the predatory spiders or avocets, whereby they can thrive and continue their role as biological controllers time and again fulfill, no matter how often there has been water supply via cycles of ebb and flow or from above took place. This allows growers to benefit optimally from the natural advantages that the predatory spiders or covetous spiders offer support in controlling pests in their cultivation processes. The purposefully creating and making available the safe shelters (wool houses) for the predatory spiders or adversaries under the cultivation pots contribute substantially to them in large to allow numbers to survive and reproduce. This contributes to an extremely stable and sustainable population that can effectively control pests, or a "standing to form an "army" that stands ready to keep emerging plagues under control. The invention lends itself to all kinds of potted plant cultivation, both for garden and kitchen herbs or houseplants, such as potted gerbera, potted hydrangea, potted lily, cyclamen, amaryllis, basil, potted anthurium, carnation, amaryllis, etc., as long as there are no pests, such as leafhoppers, aphids, thrips, etc., may occur that can be controlled with predatory spiders or partnerNanten. In some crops, the temperature in a greenhouse is preferably relatively low, for example below 15 degrees. Examples include cold-weather crops such as freesias, strawberries, and carnations, alstroemeria, etc.. Thanks to the invention, predatory spiders or can also arrive more quickly then. Canaries are deployed as pest controllers. The relatively warm and draft-free microclimate in the elevated shelter / nesting chambers thanks to the bell principle offers the predatory spiders or rivals have stable bases of operations to retreat to whenever necessary to withdraw for a while. As predatory spiders or adversaries, various types of arachnids from different families are deployed and various hunting methods are used, depending on the species to be controlled. various insect pests and temperatures where the predatory spiders or adversaries needs to be hunted. 5 The grow pots can be manufactured from various materials, if desired even of earthenware. Preferably, however, it is manufactured from synthetic material via injection molding, since the pot bottom wall sections forming the raised shelter / nesting chambers limits that can be reliably and cost-effectively executed airtight. The shelter / nesting chambers can be dimensioned as desired, in particular tailored to the space required for a desired preferred number shelter / nesting predatory spiders or to allow predators to house them therein. Preferably they can have a cross-sectional dimension of between 2-10 cm, in particular approximately 5 cm, be provided. Furthermore, the shelters / nesting chambers should preferably have a height of between 0.5-2 cm, in particular approximately 1 cm. In addition, the Shelter / nesting chambers preferably elevated over a free height of between 0.5-2 cm, in particular approximately 1 cm, free above the cultivation surface, or free above an underlying lie the support rim or support feet with which the growing pot rests on that growing surface. In a preferred design, the elevated shelter / nesting chambers can are furnished with inward-projecting elements in the upper spaces beneath the raised platforms wall sections, in particular partition walls and / or nesting ribs for forming compartments and / or hiding / nesting corners for the predatory spiders or adversaries. This makes the with significant advantage possible for larger numbers of predatory spiders or competitors to in to stay in the same shelter / nesting chamber while they are separated from each other held. This isolation is of particular importance because otherwise there is a risk that they start attacking or eating each other, due to territorial or cannibalistic behavior. In addition, the inwardly protruding wall sections, such as the partition walls and / or nesting ribs, with the great benefit of extra corners in the shelter / nesting chambers and thus ensure extra attractive shelters for the predatory spiders or adversaries because they They like to nest in corners in dark, quiet, and peaceful hidden places where they feel comfortable. feel and where they can eat in peace. The wall sections protruding inwards, such as the partitions and / or nesting ribs, formed angles furthermore form good locations for the predatory spiders or partners to make their webs. In a further preferred implementation form, water supply can take place via ebb and flood around the undersides of the cultivation pots placed on the cultivation surface by means of alternating supply and removal of water at the cultivation surface, whereby during the step of the bringing about a flood a water level on the cultivation plane rises to at least above a level at which the irrigation / drainage holes are located. 6 In particular, the step of bringing about a flood can then be designed to to raise the water level on the cultivation surface to at least above the underside of the Elevated shelter / nesting chambers. During the step of bringing about flooding are the elevated shelter / nesting chambers then hermetically sealed downwards sealed off by rising water level in the elevated shelter / nesting chambers air bubbles become trapped. Should the water level subsequently rise further during the flood rise, in particular even to above the upper side of the elevated area shelter / nesting chambers, then this changes nothing else about the situation. The air bubbles also remain than just being trapped underneath like air bells according to the air bubble principle equipped shelter / nesting chambers. During low tide, the air bells are open on their undersides. If the water begins to rise during high tide, the undersides will be completely covered by water. be closed off. As a result, air bubbles will rise as the water level rises. form in the shelter / nesting chambers. These air bubbles will ensure that the there resident predatory spiders or related species and webs shall remain free of water. The elevated shelter / nesting chambers thus remain safe at all times. harbors for predatory spiders or landing sites during the periodic alternation of ebb and flood, even if the water level rises above the ceiling of the shelter / nesting chambers. TenNijl the entire area around the bottom ends of the growing pots becomes submerged, can the predatory spiders or associates continue to breathe in the resulting air spaces and in remain alive. The fragile webs, as shelters and / or filled with the eggs and / or full with newly hatched predatory spiderlings, will also in the resulting air spaces remain undamaged and do not drown. In a preferred design, the elevated shelter / nesting chambers can be truncated conical with a boundary at the top formed by airtight seals ceiling wall sections of the pot bottoms and with a radial outward direction bounded by airtight perimeter wall sections of the pot bottoms. These releasing The shape lends itself well to being manufactured in a mold, and the transition angle between ceiling-wall section and perimeter wall section form good locations for the predatory spiders to drop their webs attach. In addition, the inward-projecting wall sections, such as the partition walls and / or nesting ribs, then extending up against these transition angles between ceiling wall sections and the perimeter wall sections of the pot bottoms and thereby in radial direction inwards in the spaces above under the raised platforms extend. This advantageously reinforces the pot bottoms at the raised section. shelter / nesting chambers and forms even better locations for the predatory spiders to lay their webs on have stitched 7 In a further embodiment, guide ribs may be provided that towards protruding downwards from the bottom of the pot, starting at an outer perimeter of the pot bottom and which lead over the underside of the pot bottom to the hiding / nesting chamber. These guiding ribs contribute to the predatory spiders automatically moving towards the elevated Guide located shelter / nesting chambers. In addition to this, the guide ribs there can connect to the inward ones. protruding wall sections, such as partition walls and / or nesting ribs. This contributes to further reinforcement and guidance to the most suitable nesting locations in the shelters / nesting chambers. In a further embodiment, a space underneath the raised section can be the bottom of the pot, where the raised shelter / nesting chamber is located, a form an irrigation / drainage chamber that is bounded by its own lower-lying perimeter wall section of the pot base, which irrigation / drainage chamber is equipped with a series of the irrigation / drainage holes. Thus, the water level during flood in the rise up the irrigation / drainage chamber and through the irrigation / drainage holes in the growing pot to penetrate, while the shelter / nesting chamber above remains in open connection with the surroundings can remain until the moment the rising water level reaches the underside of the shelter / nesting chamber and seals it hermetically while simultaneously traps an air bubble in it. In addition, a stepped transition may be provided between the underlying irrigation / drainage chamber and the raised shelter / nesting chamber situated above it. In addition, the shelter / nesting chamber be dimensioned in terms of cross-sectional dimensions depending the number of predatory spiders or adversaries wishing to shelter / nest therein, the underlying irrigation / drainage chamber with advantage via the stepped transition with a larger cross-sectional dimensions can be manufactured. This achieves that many volume of irrigation / drainage chamber is created to rapidly increase the water level during flood, and that much is available along the irrigation / drainage chamber pot bottom wall surface is created for providing along it with irrigation / drainage holes. This contributes to the rapid flow via the irrigation / drainage chamber into the grow pots can enter inwards and water can flow out again during ebb and flow. The duration of high water during high tide can thereby be kept limited so that the hermetic sealing of the shelter / nesting chambers as an air bell as soon as the water level the the underside thereof can also remain limited. It is then advantageous that the stepped transition is possible in an annular shape. comprises a transition wall section that connects on the one hand to the top of the underlying 8 irrigation / drainage chamber and that on the other side connects to the underside of the one above elevated shelter / nesting chamber, where this ring-shaped transition wall section of the The pot bottom can be provided with a series of irrigation / drainage holes. Similarly, the pot bottom can also advantageously have an external ring shape. comprise a connecting wall section that connects to the underside of the raised section on the one hand, in the particularly on the underside of the underlying irrigation / drainage chamber, and that on the other hand connects to the pot perimeter wall, so that this external ring-shaped connection wall section also can be equipped with a series of irrigation / drainage holes. In a preferred version, the bottom of the growing pot may be provided with a supporting edge extending in the circumferential direction below or near the perimeter wall and which is designed for supporting the growing pot on a cultivation surface. It is important here that the support edge or is locally interrupted by one or more access recesses that are designed to provide access to the predatory spiders or adjacent the shelter / nesting chamber. Further preferred forms of implementation of the invention are laid down in the dependent sub-conclusions. BRIEF DESCRIPTION OF THE FIGURES The invention will be explained below in a non-exhaustive manner on the basis of of the accompanying figures, in which: - Fig. 1 shows a perspective view from below of a preferred design of the cultivation pot with shelter / nesting chamber according to the invention; - Fig. 1a shows an enlarged section view of Fig. 1; - Fig. 2 shows a perspective view of the growing pot seen from above; - Fig. 3 shows a longitudinal section of the growing pot placed on a tray-shaped ebb and flow. flood cultivation floor at low tide; - Figs. 4a and 4b show the cultivation pot of Fig. 3 at two water levels at the time of rising water levels at flow in accordance with the method according to the invention; and - Fig. 5 shows a photograph viewed from below of a variant of the growing pot according to the invention. In Fig. 1-3, the entire growing pot is indicated by the reference number 1. The growing pot 1 comprises a pot base 2. Furthermore, growing pot 1 comprises a pot perimeter wall 3 which is extends upwards from the bottom of the pot 2. The growing pot 1 shown is rotationally symmetrical 9 around a central vertical centerline. Together, the pot bottom 2 and the pot perimeter wall 3 an inner space for incorporating substrate therein and a therein growing potted plant. At the top of the pot perimeter wall 3 there is another pot collar 5. The pot base 2 has a profiled design that steps upwards. extending elevation. The pot base 2 comprises a substantially vertical support rim 10 which is located slightly offset inwards beneath the pot perimeter wall 3. Along the perimeter of the support edge 10 is provided with access recesses 11. The top side of the support edge 10 connects to one extending mainly inwards in a radial direction external ring-shaped connection wall section 14 containing a first series irrigation / drainage holes 15 that form a flow connection with the interior space of the cultivation pot 1 for watering, drainage, and aeration. The external ring-shaped connection wall section 14 transitions into a sloping internal upward-projecting perimeter wall section 18 that connects at the top to a located in main part extending inwards in a radial direction, internally ring-shaped transition wall section 20 containing a second series of irrigation / drainage holes 21 which also form a flow connection with the interior space of cultivation pot 1 for the purpose of watering, drainage and aeration. The internal ring-shaped transition wall section 20 transitions into a sloping internal upward-projecting perimeter wall section 24 that connects at the top to a located in radially inward-extending ceiling wall section 25. In accordance with the concept of invention, the diagonally upward projection inwards are perimeter wall section 24 and the one extending inwards in a radial direction ceiling wall section 25 executed airtight closed. Thus, the perimeter wall section is bounded. 24 and the ceiling-wall section 25 together form a raised level above the underside located of the supporting edge 10 in a mainly truncated conical shelter / nesting chamber RK according to the air bell principle. The shelter / nesting chamber RK has a height H1 of approximately 1 here. cm and an average cone diameter of approximately 5 cm. The RK shelter / nesting room is divided into sections and equipped with extra shelter / nesting corners using partition walls 30. These partition walls 30 are provided at the transition of the ceiling wall section 25 and the perimeter wall section 24. The partition walls 30 extend inwards in a radial direction from the perimeter wall section 24 and hereby, for material saving, have a height and width of approximately 0.5*H1, or approximately 0.5 cm here, has been provided. 10 At the bottom, the shelter / nesting chamber RK has been left completely open and stands thereby in open connection with those located further below the raised platform underlying space. In this underlying space, perimeter wall section 18 and the inner ring-shaped transition wall section 20 together a first essentially truncated conical section IK of an irrigation / drainage chamber IK. This first section IK of the irrigation / drainage chamber IK has a height H2 of approximately 1 cm here and a average cone diameter D2 of approximately 10 cm. In this underlying space, the support rim 10 and the external ring-shaped connection wall section 15 together a second part IK of the irrigation / drainage room IK. This second part IK of the Irrigation / drainage chamber IK has a height H3 of approximately 1 cm here and an average cone diameter D3 of approximately 20 cm. The RK shelter / nesting chamber is thus situated entirely above both series. irrigation / drainage holes 15, 21 of the irrigation / drainage chamber IK and starts with its underside at a level of H2+H3, or approximately 2 cm here, above the underside of support edge 10. On the inside of the support edge 10, reinforcement bulkheads 35 are provided which connect to the external ring-shaped connection wall section 15. These reinforcement bulkheads 35 transition into guide ribs 36 which run downwards as thickened ridges from the pot bottom 2 protrude. The guide ribs 36 lead to the shelter / nesting chamber RK, go over there in nesting ribs 36 which extend diagonally upwards along the perimeter wall section 24 that delimits the shelter / nesting chamber RK, from there in a radial direction insert inwards and there transition into the partition walls 30. In figures 3, 4a and 4b it can be seen that the cultivation pot 1 during cultivation with a growing inside potted plant (not shown) is placed on a cultivation surface TV of a tray-shaped cultivation floor. To control pests, predatory spiders or adversaries can be distributed over the potted plants. These predatory spiders or adversaries can then enter through the access cutouts 11 end up under the growing pots 1 as soon as they want to retreat to a quiet spot. In doing so, they will allow themselves to be lured further up under the profiled pot bottom 2 towards the warm, humid, and draft-free microclimate that prevails in the shelter / nesting chamber RK. The conduction ribs 36 help the predatory spiders or co-opters with this. Subsequently, they will their follow natural tendency to start making webs as shelter and / or as an egg sac in the corners provided by the nesting ribs 36 and the partitions 30. If then water via an ebb and flow system connected to the cultivation floor is supplied to the cultivation floor, the water level Hw there will rise and via both series of irrigation / drainage holes 15, 21 to provide the potted plants with water and nutrients. However, thanks to the air bell design, the water will not be able to end up in the shelter / nesting chambers RK, not even if this water level Hw, for example, rises above the 11 ceiling wall section 25 as shown in Fig. 4b. As soon as the water level HW reaches height H2+H3, namely when the underside of the perimeter wall section 24 is reached, this will cause an air bubble Lock up in the shelter / nesting chamber RK. This air bubble cannot subsequently get out of there. escape. The risen water level Hw hermetically seals the shelter / nesting chamber RK to the underside. This advantageously ensures that the predatory spiders or adversaries and their webs can withstand the tide without danger. As soon as the tide goes out again, the predatory spiders or rivals leave the shelter / nest chamber again and go hunting for Pests on the potted plants. Fig. 6 shows a variant in which the partitions have been omitted, but the inwardly protruding nesting ribs 36 have been retained. Even then, they become advantageously provides extra attachment points for the webs. In addition to the versions shown, many variants are possible. For example, the dimensions and shapes of the various parts are changed. Also, it is possible combinations to be made between advantageous aspects of the shown versions. This way, the pots can have any desired height-width ratio, have wall thickness variation, etc. instead of a central elevated located Instead of providing a shelter / nesting chamber under each growing pot, it is also possible to use multiple shelter / nesting chambers per cultivation pot in upper spaces provided below to provide for partial elevations. Furthermore, if faster irrigation / drainage is desired is, additional series of irrigation / drainage holes are provided in the wall sections that the Delineate irrigation / drainage chambers. It should be clear that various changes and modifications to the current preferred forms of execution can be applied without deviating from the scope of the invention, and therefore will be clear to the professional. It is therefore the intention is that such changes and modifications be covered by the attached conclusions. 12
