Description

Technical Field

[0001] The invention relates to the field of seedling transplantation, and in particular to a method for improving vegetation soil by utilizing water-absorbing resin. Background Art

[0002] In the process of rapid economic development, environmental improvement has always been a major and thorny issue. At present, the main method to improve environmental problems is to plant flowers, plants and trees to achieve the effects of greening roads, maintaining water and soil, preventing wind and sand, conserving water sources and regulating the climate, and seedling planting occupies the largest part of it. Seedling planting requires sufficient and continuous water to ensure its growth, but most of the water is lost due to evaporation during irrigation, causing the seedlings to die due to lack of water. In order to prevent water loss and ensure the survival of seedlings, it can be effectively solved by increasing the number of irrigation times, but this treatment method is not only time-consuming and labor-intensive, but more importantly, it wastes water resources. It is not applicable to droughts or water-scarce northern regions.

[0003] In this regard, the prior art mostly adds a water-retaining agent with a water-absorbing resin as the main component to the soil, which is beneficial to the water-absorbing and water-retaining performance of the water-absorbing resin, and absorbs or releases water according to the water content in the soil, thereby improving the soil, thereby achieving the effect of assisting in regulating the water supply balance of seedlings and improving the survival rate of seedlings. However, this method has several very obvious disadvantages:

[0004] First, the service life of the resin currently available on the market is short, and it is necessary to frequently replace or add to ensure the water absorption effect of the water retaining agent. However, because the water-absorbing resin is mainly mixed with the soil, when it is decomposed and added again, it is necessary to dig out part of the soil around the seedlings, mix it with the water-absorbing resin, and then refill it. However, such operation can easily cause the root system of the seedlings to be damaged when replacing or adding resin.

[0005] Secondly, in order to be suitable for arid and water-deficient areas, when adding water-absorbing resin, it will be soaked in aqueous solution to absorb water until it is in the state of water beads. In order to ensure that the water-absorbing resin is in the state of water beads when improving the soil, it needs to be mixed with the planting soil into a muddy state. However, if the muddy planting soil is directly used for seedling planting or transplanting, the planting soil will have too much water and cannot be discharged in time, which can easily cause the roots of the seedlings to be immersed in the overly wet soil for a long time, resulting in root rot and death.

[0006] Furthermore, the water-absorbent resin in the state of hydrogel beads is easily deposited in the lower layer of the mixed planting soil due to the gravity and the fluidity of the mud in the mud-like soil, resulting in the improvement of the planting soil being too limited and unable to be fully and evenly covered, and its effect is limited. Summary of the invention

[0007] The purpose of the present invention is to provide a method for improving vegetation soil using water-absorbing resin, which can effectively solve the problems caused by traditional improvement methods, achieve convenient replacement without damaging the root system, and comprehensively improve the soil to ensure seedling planting, thereby improving the survival rate of seedlings.

[0008] A method for improving vegetation soil using water-absorbing resin, the method for improving vegetation soil specifically comprising:

[0009] (1) using a conventional material that is not easily corruptible and water-permeable to prepare a long bag, filling the long bag with a water-absorbing resin to prepare a soil improvement bag, and placing the soil improvement bag in the solution for 2 to 3 hours until the water-absorbing resin absorbs the solution and presents a saturated water bead state;

[0010] (2) After laying a layer of sand in the planting hole, the vegetation with the soil ball is placed in it, and the positioning mechanism is sleeved on the outside of the vegetation to fix it;

[0011] (3) After the water-absorbing resin has finished absorbing the liquid, the soil improvement bag is initially positioned using the positioning mechanism, the soil improvement bag is hooked to the hook below the positioning mechanism, and the soil improvement bag is vertically positioned in the soil ditch between the planting hole and the soil ball using its own weight;

[0012] (4) After positioning, fill the planting hole with planting soil and cover the soil improvement bag at the same time. During the filling process, observe the position of the soil improvement bag at any time to avoid the soil improvement bags crossing each other;

[0013] (5) After the soil improvement bag is fixed by the limiting effect of the planting soil, it is removed from the hook and the positioning mechanism is removed, and the planting hole is continued to be filled with planting soil until the soil improvement bag is completely covered and the upper surface planting soil is compacted to make it flush with the soil around the vegetation.

[0014] The positioning mechanism is composed of a circular ring positioning ring and a plurality of cross bars radially distributed outside the circular ring positioning ring. The circular ring positioning ring is composed of two semicircular arcs hinged to each other at one end and detachably connected by a lock buckle at the other end.

[0015] The long strip containing bag is divided into containing cavities of equal length and not connected by hot pressing or sewing, and the containing cavities are filled with equal amounts of water-absorbing resin and then sealed to prepare soil improvement bags.

[0016] The containing cavity is a cylindrical structure with a diameter of 3 to 5 cm and a height of 3 to 5 cm, and 0.4 to 0.6 g of a water-absorbing resin with a size of 0.10 to 0.15 mm needs to be filled in the containing cavity.

[0017] When the water-absorbing resin absorbs the aqueous solution to form water beads, its volume increases to 80-120 times of the original volume and inflates the soil improvement bag.

[0018] The positioning mechanism selects circular positioning rings of different sizes according to the size of the soil ball of the vegetation, and passes the semicircular arcs around the branches of the vegetation and connects them with locks. The cross bars span the planting holes and are fixed on the soil above the planting holes, so that the circular positioning rings are set on the vegetation and suspended on the soil ditch between the planting holes and the soil ball.

[0019] The soil improvement bag in the state of hydrogel beads is hung on a hook below the positioning mechanism and is vertically positioned in the planting hole by its own weight; the bottom of the soil improvement bag is placed on the upper surface of the sand in the planting hole, and its top is at least 1 / 3 lower than the height of the planting hole.

[0020] Each cubic meter of planting soil backfilled in the planting hole requires 0.2 to 0.3 kg of water-absorbing resin.

[0021] When the soil improvement bag is fixed by using planting soil, the planting soil is filled to a height of 1 / 2-9 / 10 of the length of the soil improvement bag.

[0022] The solution is water.

[0023] The present invention has the following beneficial effects:

[0024] (1) The method for improving vegetation soil of the present invention effectively solves the defects of traditional water-absorbing resins that are difficult to replace and replenish. The water-absorbing resin can be replaced quickly and conveniently, and the damage to the root system of seedlings caused by replacement is reduced. When the soil improvement bag is used for the first time, the water-absorbing resin absorbs water into a hydrogel state, and the soil improvement bag expands to its maximum volume for use. When the water-absorbing resin is replaced, when the water-absorbing resin is dehydrated and shrunk and the soil is dry or soft, there will be a gap between the hole where the soil improvement bag was originally placed and the soil improvement bag. It is only necessary to dig up the soil above the soil improvement bag, and then rotate the soil improvement bag so that the gap between it and the hole is obvious and there is no adhesion, so that it can be quickly and conveniently pulled out for replacement. Furthermore, the long storage bag is made of conventional materials that are not easy to corrupt and are water-permeable. The roots of the seedlings will grow around objects that are difficult to penetrate. Therefore, the damage to the roots of the seedlings will be minimized when the soil improvement bag is replaced. Finally, when replacing the soil improvement bag, a dry absorbent resin is used. Its volume is smaller, and compared with the holes formed by the first use of the soil improvement bag in the water-gelled bead state, it can be easily replenished and replaced.

[0025] (2) The method of improving soil for vegetation of the present invention can effectively solve the problem of soaking and rotting of roots caused by excessive wetting of the planting soil, which is caused by the mixing of water-absorbing resin in the state of hydrogel beads with planting soil into a slurry for planting vegetation. The water-absorbing resin in the state of hydrogel beads can be individually positioned and evenly distributed in the planting hole through the long holding bag and then covered with soil for planting, which can not only properly ensure the softness and water content of the planting soil, but also ensure that the soil has a suitable water holding capacity for a long time to meet the growth needs of vegetation.

[0026] (3) The present invention uses conventional materials that are not easily corrupted and permeable to water to prepare long strip containing bags for arranging water-absorbent resins, and uses hot pressing or sewing to distribute the water-absorbent resins in equal amounts and at equal distances in the longitudinal direction in non-interconnected containing cavities, thereby improving the uniformity, convenience and efficiency of improving vegetation soil with the water-absorbent resins.

[0027] (4) Water-absorbent resin absorbs water and expands when watering to prevent rapid water loss. When there is water shortage, it releases water and shrinks to meet the water balance of vegetation, thereby increasing the survival rate of vegetation. It is suitable for arid areas where water is easily volatile. In addition, the repeated expansion and contraction of water-absorbent resin can loosen the soil and effectively solve the problem of soil compaction. BRIEF DESCRIPTION OF THE DRAWINGS
