Description

Technical Field

[0001] This invention relates to the field of plant cultivation technology, and more specifically, to a multi-dimensional niche regulation method for garlic clove cultivation. Background Technology

[0002] *Malania oleifera* is a rare and endangered tree species endemic to the Youjiang River basin in southeastern Yunnan and western Guangxi, my country. Its kernels are rich in nervonic acid and have extremely high medicinal and economic value. However, the artificial cultivation of *Malania oleifera* faces two major technical bottlenecks: Physiological bottleneck: Garlic bulbs are semi-parasitic plants with fleshy roots that are extremely prone to rotting and have very poor natural regeneration ability. During the seedling stage, their roots must attach to the roots of the host plant to absorb water and nutrients normally; otherwise, the survival rate is extremely low.

[0003] Ecological bottleneck: Garlic seedlings prefer shade and dislike direct sunlight, but mature plants require ample sunlight to grow rapidly, flower, and bear fruit. Traditional planting methods struggle to balance their varying light requirements at different growth stages, resulting in low transplant survival rates and slow growth.

[0004] Currently, although attempts have been made to cultivate garlic cloves by finding host plants, problems remain, including inappropriate host selection, slow establishment of symbiotic relationships, and a disconnect between seedling management and later growth environment. A highly efficient, stable, and scalable integrated technology system has not yet been established. Therefore, there is an urgent need for a comprehensive planting method that can simulate the natural ecological niche of garlic cloves throughout their entire growth cycle to solve the technical challenges from seedling to forestation. Therefore, a multi-dimensional ecological niche regulation planting method for garlic cloves is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the problems raised in the existing background technology. In order to achieve the above-mentioned purpose, this invention provides the following technical solution: a multi-dimensional ecological niche regulation planting method for garlic fruit, step (1) symbiotic seedling: select a host plant, and simultaneously sow garlic fruit seeds and host plant seeds or bud seedlings in the same seedling container, and form a garlic fruit-host symbiotic seedling group through symbiotic cultivation; Step (2) Forest selection and preparation: Select existing broad-leaved forests with a canopy density of 0.6-0.7 as intercropping forest land; Step (3) Intercropping under the forest: Transplant the symbiotic seedling clusters obtained in step (1) to the selected broad-leaved forest; Step (4) Gradual light regulation: After planting, adjust the canopy closure of the forest stand in stages to guide the garlic fruit from a shade-loving state to a light-loving state.

[0006] As a preferred technical solution of the present invention, the host plant in step (1) is one or more of the following: tung oil tree, acacia, camellia, and pigeon pea.

[0007] As a preferred technical solution of the present invention, in the symbiotic cultivation process of step (1), a shade net with a light transmittance of 60-65% is set up in the nursery, and conventional nursery management such as watering and weeding is carried out. The nursery is cultivated for 4-6 months until the garlic fruit and the root system of the host plant intertwine to establish a parasitic relationship.

[0008] As a preferred technical solution of the present invention, in step (1), the seedling container is a non-woven nutrient cup with a specification of 16cm×18cm. The cup is filled with a seedling light substrate. The seedling light substrate is made by mixing coconut coir, peat soil and mushroom residue in a volume ratio of 1:1:2, adding EM microbial agent and fermenting for 3 months to decompose. The substrate moisture content is 60-65%.

[0009] As a preferred technical solution of the present invention, in step (1), the garlic fruit seeds are treated as follows before sowing: collect fully mature garlic fruit, remove the fleshy shell and wash with clean water, soak in 2-3‰ potassium permanganate solution for 24 hours, take them out and drain them and place them on a sand bed to germinate. The humidity of the germination sand bed is maintained at 45-55%, and a shade net with a light transmittance of 75% is covered above the sand bed.

[0010] As a preferred technical solution of the present invention, step (3) of intercropping under the forest specifically includes: tearing open the seedling container outside the symbiotic seedling group, inserting the symbiotic seedling group with light substrate into the pre-dug 50cm×50cm×50cm planting hole, one seedling per hole, backfilling the soil slightly higher than the original ground level by 10-15cm to form a tree basin, watering thoroughly to settle the roots, covering with 100cm×100cm weed control cloth and compacting it.

[0011] As a preferred technical solution of the present invention, 10 kg of seedling light substrate and 0.5 kg of Bacillus subtilis microbial fertilizer are pre-applied into the planting hole, and the topsoil is backfilled to 3 / 4 of the hole height and mixed evenly.

[0012] As a preferred technical solution of the present invention, step (4) gradual light regulation specifically involves maintaining the canopy closure of the forest stand at 0.6-0.7 in the first year after planting; lightly thinning in the second year, removing diseased and insect-infested branches and overly dense lower branches to reduce the canopy closure to about 0.55; and thinning again in the third year, removing poorly growing trees and non-target tree species to reduce the canopy closure to 0.4-0.5.

[0013] As a preferred technical solution of the present invention, it also includes a microbial community cultivation step in the planting hole: after the plants have survived, the base of the garlic rootstock is drenched with 800 times diluted Trichoderma harzianum solution at a dosage of 1000 mL / plant every 60 days.

[0014] As a preferred technical solution of the present invention, the intercropping time is selected before the arrival of high temperature weather in March to May of the following year, and the forest land is selected as secondary broad-leaved forest mainly composed of Fagaceae and Lauraceae.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Revolutionary improvement in survival rate: By growing seedlings in the same cup, a stable parasitic relationship between the garlic bulb and the host is ensured before the seedlings are removed from the nursery. This solves the key problems of easy rot of the fleshy root system and difficulty in parasitism, and greatly improves the survival rate of transplanted seedlings.

[0016] 2. Precise Niche Simulation and Regulation: This invention is not simply about afforestation, but rather about the multi-dimensional and dynamic precise regulation of the root niche (parasitic relationship) and photonic niche (light conditions) of *Gnaphalium affine*. It perfectly simulates and optimizes the survival strategy of *Gnaphalium affine* under natural conditions.

[0017] 3. Seamless growth process: By organically combining the accompanying seedlings with the gradual light regulation under the forest, an integrated technical chain of seedling cultivation-transplanting-growth promotion is formed, which solves the contradiction of the disconnect between the environmental requirements of the seedling stage and the growth stage, and realizes the healthy and rapid growth of garlic fruits from seedlings to mature plants.

[0018] 4. Efficient use of resources: Intercropping with existing secondary forests or plantations does not occupy new arable land resources, and the transformation and upgrading of existing forest stands are achieved through gradual thinning. It is an efficient and ecological understory economic model.

[0019] 5. Highly operable and easy to promote: The selected host plants are common and readily available, and the technical steps are clear and specific, making it easy to promote and apply in the vast rural areas where garlic fruit is suitable for growth. This is of great significance for protecting this rare species and developing rural characteristic industries. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0022] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, in the absence of conflict, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Example 1: A multi-dimensional ecological niche regulation method for garlic fruit cultivation, comprising the following steps: Step 1. Accompanying seedlings: (1) Host selection: Select one or more tree species from tung oil tree, acacia, camellia, and pigeon pea as host plants.

[0024] (2) Synchronous sowing: Sow garlic seeds and the seeds (or buds) of the selected host plant in the same nutrient cup or seedling container at the same time.

[0025] (3) Symbiotic cultivation: The nursery is managed in a unified manner so that the roots of the garlic fruit seedlings can be forced to come into early contact with the roots of the host plant in a limited container space and establish a parasitic relationship, forming a garlic fruit-host symbiotic seedling cluster. At this stage, robust garlic fruit seedlings that have been successfully parasitized are cultivated.

[0026] Step 2. Forest Land Selection and Preparation: Existing broad-leaved forests with a canopy closure of 0.6-0.7 were selected as intercropping sites. This canopy closure provides ideal shade conditions for garlic seedlings.

[0027] Step 3. Intercropping under the forest canopy: (1) Transplant the garlic fruit-host symbiotic seedlings obtained in step 1 to the selected broad-leaved forest.

[0028] (2) Utilize the shaded environment formed by the upper forest trees to meet the shady characteristics of garlic seedlings during the seedling stage and ensure a high survival rate after transplanting.

[0029] Step 4. Gradual illumination control: (1) In the first year after planting: maintain the original canopy density (0.6-0.7) to allow the garlic seedlings to recover and take root in a stable shaded environment.

[0030] (2) In the second and third years after planting: start to gradually prune and thin the upper broad-leaved forest. Cut off the overly dense branches and some non-target tree species in batches and years, and gradually reduce the canopy closure from 0.6-0.7 to below 0.5.

[0031] (3) Through this gradual regulation, the light exposure time under the forest can be gradually increased, and the garlic fruit can be smoothly guided from the shade-loving state of the seedling stage to the light-loving state of the growth stage, thus promoting its photosynthesis and rapid growth.

[0032] Example 2: A multi-dimensional ecological niche regulation planting method for garlic fruit, the garlic fruit planting base in Liuneng Village, Longchuan Town, Youjiang District, Baise City, Guangxi Province, adopted the technology of this invention throughout the process.

[0033] Seedling stage (October-November of the same year) Seed treatment: Collect fully mature garlic cloves and tung oil trees (the ripening period of garlic cloves, tung oil trees, and camellia oil trees is basically the same, and the seed treatment method is the same; other associated tree species such as acacia and pigeon pea seeds do not require treatment), remove the fleshy shells, wash with clean water, soak in a 2-3‰ potassium permanganate solution for 24 hours, remove and drain the water, and place in a sand bed to germinate. During the germination process, maintain the humidity of the sand bed at 45-55%, and cover the sand bed and the surrounding area with a 75% light transmittance shade net.

[0034] Preparation of seedling substrate: Mix coconut coir, peat moss, and mushroom substrate in a volume ratio of 1:1, with a moisture content of 60-65%. Mix thoroughly with EM microbial agent and ferment for three months, turning the pile 5-6 times during this period. Once fully decomposed, it is ready for use.

[0035] Seedling cultivation in cups: Select 16cm×18cm non-woven fabric nutrient cups, fill them with lightweight seedling substrate, and place one germinated garlic clove seed and one germinated symbiotic tree seed (tung oil or camellia seed) in each cup. Albizia julibrissin and pigeon pea seeds do not require pre-germination; they can be placed directly into the nutrient cup along with the germinated garlic clove seeds. Cover with 2-3 cm of lightweight substrate. Cover the nursery with a 60-65% light transmittance shade netting above and around the seedlings, and perform normal nursery management such as watering and weeding. After approximately 4-6 months, the roots of the symbiotic tree species will intertwine with the roots of the garlic clove seedlings within the cups, successfully establishing a parasitic relationship and forming robust symbiotic seedlings ready for transplanting.

[0036] Forest land selection (January-February of the following year) Select a secondary broad-leaved forest with a canopy closure of about 0.65 (mainly Fagaceae, Lauraceae, etc.), clear the understory of weeds and vines, dig planting holes (50cm×50cm×50cm), apply 10 kg of the above-mentioned lightweight substrate and 0.5 kg of Bacillus subtilis microbial fertilizer to each hole, backfill the topsoil to 3 / 4 of the hole height, and mix thoroughly.

[0037] Intercropping under trees (before the high temperatures arrive in March-May of the following year) Tear off the non-woven fabric cups surrounding the symbiotic seedling clusters. Transplant the clusters, containing the lightweight substrate, into the pre-dug planting holes, one seedling per hole. Backfill the soil slightly above the original ground level, creating a planting basin that is slightly higher around the edges and lower in the center. Water thoroughly to settle the roots. Cover the planting holes with a 100cm x 100cm weed control fabric (cut a slit along one edge of the fabric down to the center of the diagonal so the seedling can pass through). Secure the slit and edges of the fabric with soil to prevent the planting basin from drying out.

[0038] Microbial community culture in planting holes After the plants have survived, in order to cultivate a healthy root microbial community and prevent root rot, apply a 1000mL solution of Trichoderma harzianum to the roots every 60 days in conjunction with irrigation. Slowly pour the solution around the base of the plant's rootstock to ensure full penetration.

[0039] After a three-year transition period of light regulation and management, the garlic pods have adapted to the gradually increasing light intensity and entered a rapid growth phase.

[0040] In the first year after transplanting (from March of that year to October of the following year): Do not interfere with the upper trees at all, maintain the canopy closure at around 0.65, and ensure that the garlic seedlings safely pass through the seedling establishment period.

[0041] In the second year after transplanting (November of the following year): the upper forest trees are lightly thinned for the first time, mainly removing diseased and insect-infested branches and some overly dense lower branches, reducing the canopy closure to about 0.55.

[0042] In the third year after transplanting (October of the third year): a second thinning was carried out, cutting down some poorly growing trees and non-target tree species, and finally reducing the canopy closure of the forest to 0.4-0.5.

[0043] Using this method, the one-year survival rate of garlic berries in the experimental area reached over 92%, and the three-year retention rate reached over 86%. The one-year survival rate and three-year retention rate are more than twice that of conventional planting methods, and the average growth is significantly higher than that of traditional direct afforestation areas.

[0044] Example 3: A multidimensional ecological niche regulation planting method for garlic fruit, step (1) companion seedling: select host plants, and simultaneously sow garlic fruit seeds and host plant seeds or bud seedlings in the same seedling container, and form garlic fruit-host symbiotic seedling clusters through symbiotic cultivation; Step (2) Forest selection and preparation: Select existing broad-leaved forests with a canopy density of 0.6-0.7 as intercropping forest land; Step (3) Intercropping under the forest: Transplant the symbiotic seedling clusters obtained in step (1) to the selected broad-leaved forest; Step (4) Gradual light regulation: After planting, adjust the canopy closure of the forest stand in stages to guide the garlic fruit from a shade-loving state to a light-loving state.

[0045] The host plant mentioned in step (1) is one or more of the following: tung oil tree, acacia, camellia, and pigeon pea.

[0046] In step (1) during the symbiotic cultivation process, a shade net with a light transmittance of 60-65% is set up in the nursery, and routine nursery management such as watering and weeding is carried out. The cultivation lasts for 4-6 months until the garlic fruit and the root system of the host plant intertwine to establish a parasitic relationship.

[0047] In step (1), the seedling container is a non-woven nutrient cup with a specification of 16cm×18cm. The cup is filled with a seedling light substrate. The seedling light substrate is made by mixing coconut coir, peat moss and mushroom residue in a volume ratio of 1:1:2, adding EM microbial agent and fermenting for 3 months to decompose. The substrate moisture content is 60-65%.

[0048] In step (1), the garlic fruit seeds are treated as follows before sowing: collect fully mature garlic fruit, remove the fleshy shell and wash with clean water, soak in 2-3‰ potassium permanganate solution for 24 hours, take them out and drain them, and place them on a sand bed to germinate. The humidity of the germination sand bed is maintained at 45-55%, and a shade net with a light transmittance of 75% is covered on the sand bed.

[0049] Step (3) Intercropping under the forest includes: tearing open the seedling container outside the symbiotic seedling group, inserting the symbiotic seedling group with light substrate into the pre-dug 50cm×50cm×50cm planting hole, one seedling per hole, backfilling the soil slightly higher than the original ground level by 10-15cm to form a tree basin, watering thoroughly to settle the roots, covering with 100cm×100cm weed control cloth and compacting it.

[0050] Before planting, apply 10 kg of seedling light substrate and 0.5 kg of Bacillus subtilis microbial fertilizer to the planting hole, and then backfill the topsoil to 3 / 4 of the hole height and mix well.

[0051] Step (4) Gradual light regulation is as follows: In the first year after planting, maintain the canopy closure of the forest stand at 0.6-0.7; in the second year, lightly thin out the trees, remove diseased and insect-infested branches and overly dense lower branches, and reduce the canopy closure to about 0.55; in the third year, thin out the trees again, cut down trees with poor growth and non-target tree species, and reduce the canopy closure to 0.4-0.5.

[0052] It also includes the following steps for cultivating the microbial community in the planting hole: after the plants have survived, every 60 days, the base of the garlic rootstock is treated with 1000 mL of 800-fold diluted Trichoderma harzianum solution per plant.

[0053] The intercropping time should be chosen before the arrival of high temperatures in March to May of the following year, and the forest land should be secondary broad-leaved forests dominated by Fagaceae and Lauraceae families.

[0054] Example 4: A biomimetic cultivation method for garlic cloves based on multidimensional niche dynamic regulation, comprising the following steps: Step (1) Pre-construction of symbiotic seedlings and symbiotic strength: Select host plants with root exudate induction capabilities, and simultaneously sow pretreated garlic clove seeds and host plant seeds or bud seedlings in the same seedling container. Conduct symbiotic cultivation in a controlled microenvironment to form garlic clove-host symbiotic seedling clusters with a stable parasitic-symbiotic coupling relationship. The co-occurrence intensity (S) is dynamically evaluated according to the following formula: In the formula: : Co-occurrence intensity at time t (dimensionless, 0 : Length of intertwining between garlic clove and host plant root system at time t (cm); : Maximum possible interlacing length (experimental measurement); : Rhizosphere carbon flux at time t (μmol C·m -2 ·s -1 ); Carbon exchange saturation threshold; : Abundance of beneficial rhizosphere microorganisms at time t (CFU / g soil); Initial microbial abundance; Weighting coefficients, satisfying It was calibrated by principal component analysis (PCA).

[0055] Step (2) Forest niche suitability screening: Select canopy density Secondary broad-leaved forests of Fagaceae-Lauraceae with soil pH ∈ [5.5, 6.5] and organic matter content ≥ 3.0% are used as intercropping forests; Among them, the comprehensive ecological niche suitability of forest land Calculated by the following formula: In the formula: The trigonometric membership function has a peak value of 0.65. OM represents the percentage of organic matter; For normalized weights ; when It was determined to be a highly suitable forest area.

[0056] Step (3) Precision intercropping under the forest canopy and micro-topography reconstruction: Plant the symbiotic seedling clusters into planting holes with dimensions of 50 cm × 50 cm × 50 cm. Apply 10 kg of seedling light substrate and 0.5 kg of Bacillus subtilis fertilizer to each hole. Backfill the soil to form a tree basin 10–15 cm higher than the original ground level and cover it with 100 cm × 100 cm weed control cloth. Among them, tree basin height Compared with the local average annual rainfall Satisfying empirical relationships: Step (4) Gradual regulation of light niche migration: Based on the physiological development stages of garlic fruit, the canopy density of the forest stand was reduced in a three-year step-by-step manner to achieve a leap in ecological niche from shade-loving to sun-loving; Step (5) Directed reinforcement of rhizosphere microbial community: After the plants have established themselves, the roots are drenched with 1000 mL of 800-fold diluted Trichoderma harzianum solution per plant every 60 days, while the relative abundance of Trichoderma spp. in the rhizosphere is monitored simultaneously. ,when Supplementation intervention should be initiated at the appropriate time.

[0057] The host plant mentioned in step (1) is one or more of the following: tung oil tree (Vernicia fordii), acacia (Albizia odoratissima), camellia (Camellia oleifera), or pigeon pea (Cajanus cajan). The selection is based on the concentration of flavonoids in the root exudates of the host plant. This concentration can significantly induce the formation of haustoria in garlic cloves (p<0.01).

[0058] Step (1) During the symbiotic cultivation period, light transmittance is used.
