Description

Technical Field

[0001] The present invention relates to the technical field of plant planting auxiliary devices and methods, and in particular to a planting auxiliary device and a planting method thereof for Castanea henryi (Castanea henryi) under a small white tea forest. Background Art

[0002] Chinese patent publication number CN117256401A discloses a cultivation method for intercropping white tea plants on chestnut trees. The method states that the spacing between chestnut trees and white tea plants should not be too close, as this can lead to uneven nutrient distribution and affect the quality of future white tea harvested from the white tea plants. Specifically, the spacing between the chestnut trees and the white tea plants is 4-5 meters. While increasing the spacing between the chestnut trees and the white tea plants can help maintain soil and water, it weakens the growth advantage of the chestnut understory for the white tea plants. The chestnut trees shed their leaves between October and April of the following year, during which time their canopy's shading effect on the understory is weakened. However, between April and September of the following year, the chestnut trees gradually grow leaves, increasing their canopy's shading effect on the understory from June to August. And in the prior art, the spacing of the small white tea plant and the chinensis plant is more than 4 meters, then can't be fully shielded by the chinensis tree crown.The inventor finds, if the spacing between the chinensis and the small white tea is 1.5-2 meters, can be fully covered by the tree crown of the chinensis, on the one hand can utilize the chinensis leaf-falling period between October to April of next year, reduce and shield, absorb sufficient illumination, be beneficial to the conversion of the small white tea contained substance, and between April to September of next year, can utilize the chinensis leaf to provide shielding for the small white tea plant, make it accept diffuse light, avoid too strong illumination intensity to suppress its growth and material conversion.But if the spacing between the chinensis and the small white tea is 1.5-2 meters, the allelopathic substance secreted by the chinensis root system can have a negative impact on the growth quality of the small white tea, therefore formed contradiction. Summary of the Invention

[0010] The horizontal distance between each second electrode and the first electrode is 90 cm, the distance between the second electrode and the ground is 25 cm, and the potential of the second electrode is -0.15 V;

[0011] The horizontal distance between each third electrode and the adjacent second electrode is 90 cm, the distance between the second electrode and the ground is 15 cm, and the potential of the third electrode is -0.35V.

[0012] Furthermore, in the above-mentioned auxiliary device for planting Castanea henryi under a small white tea forest, the third electrode and the adjacent second electrode are distributed in an equilateral triangle array.

[0013] Furthermore, in the above-mentioned auxiliary device for planting small white tea under the chestnut forest, the first electrode is set to deviate from the extension direction of the main root of the chestnut tree; the third electrode is set to deviate from the extension direction of the main root of the small white tea plant.

[0014] Furthermore, in the above-mentioned auxiliary device for planting Castanea henryi under a small white tea forest, the material of the first electrode, the second electrode and the third electrode is selected to be isostatically pressed graphite with a density greater than or equal to 1.8 g / cm³.

[0015] Furthermore, in the above-mentioned auxiliary device for planting small white tea under the chestnut forest, the current density between the first electrode and the second electrode is 0.15mA / cm²-0.08mA / cm², and the current density between the second electrode and the third electrode is 0.15mA / cm²-0.08mA / cm².

[0016] Furthermore, in the above-mentioned auxiliary device for planting Castanea henryi under a small white tea forest, the surfaces of the first electrode, the second electrode and the third electrode are plated with a TaN coating having a thickness of 200 nm.

[0018] The present invention also relates to a method for planting small white tea under a Castanea henryi forest. Based on the above-mentioned auxiliary device for planting small white tea under a Castanea henryi forest, the planting method comprises the following steps:

[0019] Transplanting the chestnut tree into the soil, before covering the roots of the chestnut tree with soil, burying the first electrode and the second electrode at corresponding positions, and then covering with soil;

[0022] The beneficial effects of the present invention are as follows: the planting distance between the small white tea plants and the chinensis trees is reduced to 150-160 cm, the shading ability of the chinensis tree crowns increases from weak to strong and then to weak between April and September, and in particular, the densest shading effect can be provided for the small white tea plants under the forest from June to August, thereby preventing the small white tea from being sunburned due to excessive light during this period, thereby affecting the quality of the tea leaves; and from October to April of the following year, the deciduous property of the chinensis trees is utilized, so that the small white tea plants are not shaded during this period, and are exposed to sufficient light during this period, which is beneficial to the synthesis of flavor substances in the tea leaves, thereby improving the quality of the tea leaves. By arranging the first electrode, the second electrode and the third electrode at specific positions in the planting area, the phenolic acid substances such as ferulic acid and coumaric acid in the root secretions of the henryi tree are enriched toward the first electrode due to their negatively charged characteristics through the attraction of the high potential of the first electrode, thereby preventing these substances from migrating to the roots of the white tea plants and affecting the transmission of their auxin signals, thereby preventing these substances from inhibiting the development of their lateral roots and the absorption of nutrients. On the other hand, by designing the distribution and potential of each electrode, the flavonoids such as kaempferol glycosides secreted by the henryi roots are electrically neutral and are basically not affected by the electrodes but migrate toward the anode. They can migrate normally in the soil to the roots of the white tea plants, because these substances can induce the white tea trees to produce defensive aroma substances such as linalool and geraniol, thereby improving the quality and taste of the white tea.

[0027] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figure 1 as well as Figure 2 The specific embodiment of the present invention relates to a planting auxiliary device for small white tea under a chestnut forest. Six small white tea plants 2 are planted in a circular array with a chestnut tree 1 as the center. The horizontal distance between the small white tea plants 2 and the chestnut tree 1 is 150-160 cm. The planting auxiliary device includes:

[0029] a first electrode 3, wherein the first electrode 3 is disposed in the soil below the trunk of the chestnut tree 1, the distance between the first electrode 3 and the ground is 30-50 cm, and the electric potential of the first electrode 3 is 0.2 to 0.3;

[0030] Second electrode 46 second electrodes 4 are arranged in a circular array with the first electrode 3 as the center in the soil. The horizontal distance between each second electrode 4 and the first electrode 3 is 80-100 cm, and the distance between the second electrode 4 and the ground is 20-30 cm. The potential of the second electrode 4 is -0.2 to -0.1 V;

[0031] The third electrode 5, six third electrodes 5 are distributed in a circular array in the soil with the first electrode 3 as the center. The horizontal distance between each third electrode 5 and the adjacent second electrode 4 is 80-100 cm, the distance between the second electrode 4 and the ground is 10-20 cm, and the electric potential of the third electrode 5 is -0.4 to -0.3 V; the third electrode 5 is located under each small white tea plant 2.

[0032] In the above embodiment, the planting distance between the small white tea plants 2 and the chinensis tree 1 is reduced to 150-160 cm. The shading ability of the crown of the chinensis tree 1 increases from weak to strong and then from strong to weak between April and September. In particular, from June to August, it can provide the densest shading effect for the small white tea plants 2 under the forest, thereby avoiding sunburn of the small white tea due to excessive light during this period, thereby affecting the quality of the tea. Between October and April of the following year, the deciduous property of the chinensis tree 1 is utilized, so that the small white tea will not be shaded during this period, and the small white tea plants 2 will be exposed to sufficient light during this period, which is beneficial to the synthesis of tea flavor substances, thereby improving the quality of the tea. By arranging the first electrode 3, the second electrode 4 and the third electrode 5 at specific positions in the planting area, the phenolic acid substances such as ferulic acid and coumaric acid in the root secretions of the henryi tree 1 are enriched in the direction of the first electrode 3 due to their negatively charged characteristics through the attraction of the high potential of the first electrode 3, thereby preventing these substances from migrating to the roots of the small white tea plant 2 and affecting the transmission of its auxin signal, thereby preventing these substances from inhibiting the development of its lateral roots and the absorption of nutrients. On the other hand, by designing the distribution and potential of each electrode, the flavonoids such as kaempferol glycosides secreted by the henryi root system are electrically neutral and are basically not affected by the electrodes and migrate toward the anode. They can migrate normally in the soil to the roots of the small white tea plant 2, because these substances can induce the small white tea tree to produce defensive aroma substances such as linalool and geraniol, thereby improving the quality and taste of the small white tea.

[0033] In the above embodiment, connecting each electrode to a power supply module so that it is controlled at a specific potential is an existing conventional technology and is not the research focus of the present invention. Therefore, this part will not be described in detail. For example, a photovoltaic energy storage unit is set up to convert ambient light into electrical energy and store it in a lithium battery storage pack, and the potential of each electrode is controlled by a multi-channel constant potentiostat.

[0034] Phenolic acids (such as ferulic acid and coumaric acid): Under neutral to slightly acidic soil conditions (pH 5.5-7.0), the carboxylic acid group (-COOH) partially dissociates into -COO⁻, which carries a negative charge and migrates toward the anode (chestnut root zone).

[0035] Flavonoids (such as kaempferol glycosides): The hydroxyl group (-OH) in the molecular structure has a weak polarity under neutral conditions and is electrically neutral as a whole. It is basically not affected by the electrode and migrates to the anode.

[0036] The electric field induces directional flow of soil pore water (from anode to cathode), further accelerating the migration of charged species:

[0037] As a preferred supplementary solution, the anode area (castanum root) can be treated by applying iron oxyhydroxide nanoparticles to complex phenolic acid through coordination bonds (complexation constant logK = 5.8);

[0038] Another function of the third electrode 5 is that the weak electric field stimulates the upregulation of flavonoid biosynthesis genes (CHS and F3H) in the rhizosphere of tea plants (expression levels increase by 1.5-2 times). The weakly reducing environment in the cathode region also protects flavonoids from oxidative degradation.

[0039] Preferably, the distance between the first electrode 3 and the ground is 40 cm, and the potential of the first electrode 3 is 0.25;

[0040] Preferably, the horizontal distance between each second electrode 4 and the first electrode 3 is 90 cm, the distance between the second electrode 4 and the ground is 25 cm, and the potential of the second electrode 4 is -0.15 V;

[0041] Preferably, the horizontal distance between each third electrode 5 and the adjacent second electrode 4 is 90 cm, the distance between the second electrode 4 and the ground is 15 cm, and the potential of the third electrode 5 is -0.35V.

[0042] Preferably, the third electrodes 5 and the adjacent second electrodes 4 are distributed in an equilateral triangle array.

[0043] Preferably, the first electrode 3 is arranged in a direction away from the main root extension direction of the Castanea chinensis tree 1; the third electrode 5 is arranged in a direction away from the main root extension direction of the Camellia sinensis plant 2;

[0044] In the above embodiment, as the planting time increases, the main roots of the chestnut tree 1 and the small white tea plant 2 will grow and extend downward. The electrodes are set in a direction deviating from the extension of the main roots, which can avoid the main root growth being restricted or interfering with the corresponding electrodes.

[0045] Preferably, the material of the first electrode 3, the second electrode 4 and the third electrode 5 is isostatic graphite with a density greater than or equal to 1.8 g / cm³.

[0046] Preferably, the current density between the first electrode 3 and the second electrode 4 is 0.15 mA / cm²-0.08 mA / cm², and the current density between the second electrode 4 and the third electrode 5 is 0.15 mA / cm²-0.08 mA / cm².

[0047] Preferably, the surfaces of the first electrode 3 , the second electrode 4 and the third electrode 5 are plated with a TaN layer with a thickness of 200 nm, thereby improving the corrosion resistance of the corresponding electrodes.

[0048] Preferably, the upper ends of the first electrode 3, the second electrode 4 and the third electrode 5 are all connected to a hard connecting rod 6, and the hard connecting rod 6 extends to the upper part of the soil.

[0049] In the above embodiment, referring to Figure 1The hard connecting rod 6 extends to the upper part of the soil, which is convenient for manual positioning of each electrode, fine-tuning of the position of each electrode as needed, and replacement and maintenance of the corresponding electrodes.

[0050] The present invention also relates to a method for planting small white tea under a Castanea henryi forest. Based on the above-mentioned auxiliary device for planting small white tea under a Castanea henryi forest, the planting method comprises the following steps:

[0051] Transplant the chestnut tree 1 into the soil. Before covering the roots of the chestnut tree 1 with soil, bury the first electrode 3 and the second electrode 4 to corresponding positions, and then cover with soil.

[0052] After the chestnut tree 1 grows to a crown radius greater than 2m, a hole is dug at the corresponding position to plant the small white tea plant 2. Before the roots of the small white tea plant 2 are covered with soil, the third electrode 5 is buried at the corresponding position and then covered with soil.

[0053] Furthermore, in the above-mentioned method for planting small white tea under the Castanea henryi forest, the timing for planting small white tea plants 2 is October.

[0054] Example 1

[0055] A method for planting small white tea plants under a chestnut forest, based on an auxiliary device for planting small white tea plants under a chestnut forest, wherein six small white tea plants are planted in a circular array with the chestnut tree as the center, and the horizontal distance between the small white tea plants and the chestnut tree is 150-160 cm. The auxiliary device comprises:

[0056] a first electrode, the first electrode being disposed in the soil below the chestnut tree trunk, the first electrode being 40 cm away from the ground, and the first electrode having an electric potential of 0.25;

[0057] Six second electrodes were placed in the soil in a circular array with the first electrode as the center. The horizontal distance between each second electrode and the first electrode was 90 cm, the distance between the second electrode and the ground was 25 cm, and the potential of the second electrodes was -0.15 V.

[0058] Six third electrodes were placed in the soil in a circular array centered around the first electrode. Each third electrode was 90 cm horizontally apart from the adjacent second electrode, and the second electrode was 15 cm apart from the ground. The potential of the third electrodes was -0.35 V. The third electrodes were located beneath each small white tea plant. The current density between the first and second electrodes was 0.15 mA / cm² to 0.08 mA / cm², and between the second and third electrodes was 0.15 mA / cm² to 0.08 mA / cm². The surfaces of the first, second, and third electrodes were coated with a TaN layer with a thickness of 200 nm.

[0059] The planting method comprises the following steps:

[0060] Transplanting the chestnut tree into the soil, before covering the roots of the chestnut tree with soil, burying the first electrode and the second electrode at corresponding positions, and then covering with soil;

[0061] After the chestnut tree grows to a crown radius greater than 2m, a hole is dug at the corresponding position in October of the same year to plant the small white tea plant. Before covering the roots of the small white tea plant with soil, the third electrode is buried in the corresponding position and then covered with soil.

[0062] If the weather is sunny for a long time, water it several times to prevent drought and frost.

[0063] Transplant seedlings of the same age with soil, and fill in the gaps to achieve full and uniform seedlings, prevent and control diseases, insects and weeds, and apply fertilizers frequently. Manual weeding should be used in the young stage of tea gardens. Fertilization in tea gardens should be done in thin layers and frequently, and multiple times should be applied according to the growing season. Apply germination fertilizer once before spring tea sprouts, and apply 3-5 times of topdressing during summer and autumn tea. Topdressing should be mainly fast-acting nitrogen fertilizer. Apply enough base fertilizer in late autumn and early winter. Base fertilizer can be animal manure, cake fertilizer or compound fertilizer. The fertilization method is the same as that of conventional tea gardens.

[0064] After the small white tea plants are planted for the fourth year, the buds are harvested in March and white tea is made through the white tea withering process.

[0065] Comparative Example 1

[0066] The planting method described in Example 1 is different in that the application of the first electrode, the second electrode and the third electrode is omitted, and other schemes remain unchanged.

[0067] Comparative Example 2

[0068] The planting method described in Example 1 is different in that the application of the first electrode, the second electrode and the third electrode is omitted, the planting distance between the castanea trees and the small white tea is increased to 5m, and other schemes remain unchanged.

The buds of the small white tea plants in each group were harvested in March after the fourth year of planting. The white tea buds in each group were withered indoors at 25°C, and white tea was produced using the same process.

[0070] The white tea prepared in Example 1, Comparative Example 1 and Comparative Example 2 was brewed, and 10 tea tasters were invited to conduct sensory evaluation on the brewed white tea. The evaluation indicators included appearance, soup color, aroma, taste and leaf bottom.

[0071] In the appearance evaluation criteria, the full score is 20 points for buds that are plump and straight, with dense hairs like snow, and uniform without impurities. Tea tasters can deduct points based on appearance defects such as insufficient plumpness of buds or unevenness of appearance.

[0072] In the evaluation criteria for tea soup color, a light apricot yellow color that is as transparent as amber in the sun is given a full score of 10 points. Tea tasters can deduct points accordingly based on the defects of the tea soup color.

[0073] The aroma evaluation criteria include a strong aroma when sniffed hot, a clear and sweet aroma when sniffed cold, and no unpleasant smells, with a full score of 30 points. Tea tasters can deduct points based on aroma defects, such as the degree of foreign smells, unpleasant smells, and the persistence of the aroma.

[0074] Among the evaluation criteria for taste, freshness like sweet spring water and a sweet aftertaste lasting for more than 3 minutes is a full score of 30 points. Tea tasters may deduct points based on the thickness of the taste, the degree of sweet aftertaste, and other taste defects.

[0075] Among the evaluation criteria for leaf bottom, the full score is 10 points if the leaf bottom is tender, even, plump, jade-white in color, and elastic when pressed with fingers.
