A method for intercropping Belamcanda chinensis in young tea gardens

Abstract

This invention relates to the technical field of intercropping Belamcanda chinensis in tea gardens, and particularly to a method for intercropping Belamcanda chinensis in young tea gardens. The method involves creating raised platforms between each row of tea trees and planting the Belamcanda chinensis on these platforms. This reduces the mutual influence between the roots of the Belamcanda chinensis and the tea tree roots, minimizing sunlight shading after the tea trees mature. Furthermore, slow-release fertilizer is buried in the raised platforms; when watering the Belamcanda chinensis, excess water flows into the slow-release fertilizer and then into the soil at the base of the tea trees, fertilizing them. A combination of sprinkler and drip irrigation facilitates separate management of the Belamcanda chinensis and the tea trees. The method includes the following steps: seed treatment, field clearing, field preparation, planting, tea seedlings, Belamcanda chinensis management, and harvesting.

Description

Technical Field

[0001] This invention relates to the technical field of intercropping Belamcanda chinensis in tea gardens, and in particular to a method for intercropping Belamcanda chinensis in young tea gardens. Background Technology

[0002] The tea tree is an evergreen shrub belonging to the genus Camellia in the family Theaceae. It often grows in clumps. The tender leaves of the tea tree can be harvested in spring and autumn to make tea, the seeds can be pressed for oil, and the trunk has a fine texture that can be used for carving.

[0003] Belamcanda chinensis is a perennial herb belonging to the genus Belamcanda of the family Iridaceae. Its rhizome is irregularly tuberous, yellow or yellowish-brown, and it is a heat-clearing medicine.

[0004] Young tea trees are difficult to generate income for growers, and the large spacing between them makes them susceptible to weed growth, affecting their growth. Therefore, methods for intercropping *Iris tectorum* under *Camellia oleifera* forests have emerged, such as the invention patent with publication number CN106577148A, and the invention patent with publication number CN107980445A, which discloses an intercropping method of *Camellia oleifera* and *Iris tectorum* in red soil mountainous areas. These methods aim to increase land yield and reduce losses during the young tea tree stage. However, existing methods for intercropping *Iris tectorum* are relatively simple. *Iris tectorum* and tea trees have different requirements for soil moisture, sunlight, fertilization, and pest and disease control, making management inconvenient and affecting the yield of both. This results in poor practicality. Therefore, there is an urgent need for a method for intercropping *Iris tectorum* in young tea gardens. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a method for intercropping Belamcanda chinensis in young tea gardens. This method involves creating raised platforms between each row of tea trees and planting Belamcanda chinensis on these platforms. This reduces the mutual influence between the roots of Belamcanda chinensis and the roots of the tea trees, minimizes the shading of sunlight by the mature tea trees, and allows for the separate management of Belamcanda chinensis and tea trees by burying slow-release fertilizer in the raised platforms. When irrigating the Belamcanda chinensis, excess water flows into the slow-release fertilizer and then into the soil at the base of the tea trees, thus fertilizing them. Furthermore, the method combines sprinkler and drip irrigation, facilitating the separate management of Belamcanda chinensis and tea trees.

[0006] The present invention provides a method for intercropping Belamcanda chinensis in young tea gardens, comprising the following steps:

[0007] Step 1: Seed Treatment

[0008] S1. Screen the tea tree seeds and Belamcanda chinensis seeds, and select the normal tea tree seeds and Belamcanda chinensis seeds that are free from diseases.

[0009] S2. Germination of tea tree seeds: Soak tea tree seeds in warm water, then bury the soaked tea tree seeds in fine sand and wait for the seeds to germinate.

[0010] S3. Germination of Belamcanda chinensis seeds: Soak Belamcanda chinensis seeds in warm water, then bury the soaked seeds in fine sand and wait for them to germinate.

[0011] S3. After sprouting, transport the cultivation pots containing tea tree seeds and Belamcanda chinensis seeds together to the field;

[0012] Step 2: Field clearing

[0013] S1. Clear weeds and debris from the fields;

[0014] S2. Plow the field, and during the plowing process, add fertilizer, adjust the pH value and add sandy soil to improve the soil environment.

[0015] S3. Conduct soil testing to ensure that the soil environment is suitable for the growth of tea trees and Belamcanda chinensis;

[0016] Step 3: Field Preparation

[0017] S1. Determine the location for tea tree planting, ensuring that the row spacing of tea trees is between 120cm and 140cm, and the longitudinal spacing of tea trees is between 26cm and 30cm.

[0018] S2. Lay a layer of clay soil between each row of tea trees, build a mound on the clay soil layer, and bury slow-release fertilizer between the mound and the clay soil layer during the process of building the mound.

[0019] Step 4: Installation of Irrigation Equipment

[0020] During the process of building the earthen platform, the irrigation equipment is buried in the middle of the platform and used to restrain the platform, reducing the risk of collapse.

[0021] Step 5: Planting

[0022] Dig holes at the designated tea tree planting location, bury the germinated tea tree seeds in the holes, and then plant the Belamcanda chinensis on the top and side surfaces of the soil platform to ensure that both the Belamcanda chinensis and the tea tree receive sunlight and to reduce the impact of the Belamcanda chinensis roots on the tea tree roots.

[0023] Step Six: Management of Tea Seedlings and Belamcanda chinensis

[0024] S1. Apply pesticides to the roots of Belamcanda chinensis using drip irrigation equipment to reduce pests and diseases in the roots of Belamcanda chinensis.

[0025] S2. The tea trees and iris are irrigated by sprinkler irrigation equipment. Since the soil below the soil platform is clay soil, the excess water in the soil platform flows into the slow-release fertilizer and then flows from the bottom of the soil platform to the soil at the bottom of the tea tree, replenishing the tea tree with nutrients and water.

[0026] S3. During the irrigation process, the pressure of the irrigation equipment is adjusted so that the irrigation equipment can spray water only onto the tea trees or only onto the iris.

[0027] Step Seven: Harvest

[0028] Once the iris is mature, it can be harvested directly without affecting the tea trees;

[0029] Once the tea trees are mature, the tea leaves can be picked directly without affecting the iris.

[0030] Preferably, in step one, when germinating tea seeds, the seeds are soaked in warm water at 30℃-35℃ for 8-10 hours, then buried in fine sand. At the same time, the seeds buried in the fine sand are kept warm and moist, and sunlight exposure is reduced until the seeds germinate.

[0031] Preferably, in step three, the thickness of the cohesive soil layer is 5-7cm, the soil platform is a trapezoid with a smaller top and a larger bottom, the top of the soil platform is a plane, and the angle between the inclined surfaces on both sides of the soil platform and the ground is 45°-65°.

[0032] Preferably, in step three, the row spacing of the tea trees is maintained at 130cm, and the longitudinal spacing of the tea trees is maintained at 28cm.

[0033] Preferably, in step three, the slow-release fertilizer is a pile of granular phosphorus and potassium fertilizer.

[0034] Preferably, the pH value of the soil is maintained between 4.0 and 6.0.

[0035] Preferably, the irrigation equipment includes a drip irrigation mechanism, multiple sets of sprinkler irrigation mechanisms, and a blocking mechanism. The multiple sets of sprinkler irrigation mechanisms are all installed on the top of the drip irrigation mechanism, and the blocking mechanism is installed at the bottom of the drip irrigation mechanism.

[0036] The drip irrigation system irrigates the Belamcanda chinensis or applies pesticides to its roots, the sprinkler system irrigates the tea trees or Belamcanda chinensis, and the blocking system blocks the sides of the soil platform to reduce its collapse.

[0037] Preferably, the drip irrigation mechanism includes two sets of drip irrigation pipes and multiple sets of connecting pipes. The two sets of drip irrigation pipes are connected by multiple sets of connecting pipes, and each set of drip irrigation pipes has several drainage holes on its side. The drip irrigation mechanism is buried in the soil platform. Water or medicine is discharged into the two sets of drip irrigation pipes, and the water pressure in the two sets of drip irrigation pipes is made consistent through multiple sets of connecting pipes. Then, water or medicine is discharged into slow-release fertilizer through several drainage holes on the two sets of drip irrigation pipes to irrigate or apply medicine to the roots of the Belamcanda chinensis, thereby improving the convenience of separate management of Belamcanda chinensis and tea trees.

[0038] Preferably, the sprinkler irrigation mechanism includes a support pipe, a control valve, and a drain pipe. The bottom end of the support pipe is connected to the top end of the top drip irrigation pipe, and the drain pipe is connected to the top end of the support pipe through the control valve. Multiple sets of nozzles are provided at both the left and right ends of the drain pipe. During sprinkler irrigation, the water in the drip irrigation pipe is allowed to enter the drain pipe by opening the control valve, and the water is sprayed out through the multiple sets of nozzles on the drain pipe to irrigate the tea trees. Alternatively, the water pressure in the drain pipe is increased by applying pressure to the inside of the drip irrigation pipe, and the water is sprayed out through the multiple sets of nozzles on the drain pipe to irrigate the iris. This improves the convenience of separate management of the iris and tea trees.

[0039] Preferably, the blocking mechanism includes two sets of partition nets and multiple sets of rods. Both sets of partition nets are installed on the bottom drip irrigation pipe via brackets, and the top ends of the multiple sets of rods are connected to the bottom ends of the two sets of partition nets respectively. After the drip irrigation mechanism is buried in the soil platform, the two sets of partition nets are positioned on the left and right sides of the soil platform respectively, while the multiple sets of rods are driven into the ground. The two sets of partition nets block the two sides of the soil platform, reducing the collapse of the soil platform and thus improving the stability of the soil platform.

[0040] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0041] 1. By planting Belamcanda chinensis on a raised platform, the impact between Belamcanda chinensis and tea trees is reduced;

[0042] 2. By using a layer of cohesive soil to block the water seeping under the soil platform, the water is directed towards the tea trees;

[0043] 3. The combination of sprinkler and drip irrigation is convenient for both pest control on the iris and watering of the iris and tea trees. Attached Figure Description
