Description

Technical Field

[0001] The invention belongs to the field of mulberry planting on saline-alkali land, in particular to a method for increasing the protein content of mulberry leaves by planting mulberry trees on saline-alkali land. Background Art

[0002] Saline-alkali land refers to land with a certain amount of salt and an alkaline pH value (greater than 8.5) due to soil salt accumulation or poor drainage. It usually includes land containing elements such as chlorides, sulfates, and sodium salts. Saline-alkali land is also accompanied by problems such as low nutrient content in the soil, low microbial activity, poor soil physical properties, and low vegetation coverage.

[0003] Mulberry is a tree with a certain salt-alkali tolerance. It can adapt to growth under high-salt and alkaline soil conditions. The roots of mulberry trees can absorb and eliminate excess salt in saline-alkali soil. At the same time, it can maintain the ion balance inside and outside the cells through ion regulation, thereby reducing the adverse effects of salt and alkali on plant growth.

[0004] Therefore, planting mulberry trees on saline-alkali land can not only improve soil quality, but also benefit ecological restoration and economic development, and help increase vegetation coverage and beautify the environment.

[0005] Although mulberry trees have a certain degree of salt-alkali resistance, scientific planting is also very important to improve the survival rate of mulberry trees in saline-alkali land. The Chinese invention patent with patent number 201711373766.4 discloses a method of propagating mulberry trees by roots on saline-alkali land. By propagating mulberry trees by roots on saline-alkali land, the survival rate of mulberry tree reproduction is greatly improved, and the reproduction time is greatly shortened, thereby improving the reproduction efficiency.

[0006] However, although the above method of planting mulberry trees in saline-alkali land has improved the survival rate of mulberry trees to a certain extent, the high salt and alkaline soil environment of the saline-alkali land is not conducive to the nutrient absorption and protein synthesis of the mulberry trees, resulting in a low protein content in the leaves of mulberry trees grown in saline-alkali land.

[0007] To this end, those skilled in the art have proposed a method for increasing the protein content of mulberry leaves by planting mulberry trees on saline-alkali land to solve the problems raised in the background art. Summary of the Invention

[0045] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0046] Example 1: As shown in the attached Figure 1 To the attached Figure 2 The present invention provides a method for increasing the protein content of mulberry leaves by planting mulberry trees on saline-alkali land, comprising improving the saline-alkali land and planting mulberry trees.

[0047] The improvement of saline-alkali land includes the following steps:

[0048] S11. Construct a drainage system: Dig drainage ditches according to the location of the saline-alkali land to drain the accumulated water in the saline-alkali land. Digging drainage ditches can effectively drain the accumulated water in the saline-alkali land, avoid the accumulation of soil salt due to excessive water, help maintain soil moisture balance, and reduce the adverse effects of salt on the growth of mulberry trees.

[0049] S12, salt washing: irrigate saline-alkali land to fully dissolve soil salt, and discharge irrigation water into the drainage ditch, and drain the soluble salt and alkali in the topsoil into the deep soil or leach out through infiltration, and seep into the drainage ditch for removal; by irrigating saline-alkali land, the salt in the soil is fully dissolved and discharged into the drainage ditch, so that the soluble salt and alkali in the soil can be discharged into the deep soil or leach out, effectively reducing the salt content of saline-alkali land, helping to improve the soil quality of saline-alkali land, and improving the permeability and air permeability of the soil, which can not only gradually transform saline-alkali land into good soil suitable for growing mulberry trees, but also promote the root development and nutrient absorption of mulberry trees, providing a more suitable growth environment for mulberry trees.

[0050] S13, tilling the soil: Deeply till the saline-alkali soil to break up soil clumps, change the soil structure, and turn the lower soil to the surface; tilling the soil helps improve soil permeability and water retention capacity, promote the root growth of mulberry trees and the nutrient absorption capacity of mulberry trees.

[0051] Mulberry tree planting includes the following steps:

[0052] S21, preparatory cultivation: before formal planting, simulate the environment of saline-alkali land for preparatory cultivation of mulberry trees; by simulating the environment of saline-alkali land for preparatory cultivation of mulberry trees, the adaptability and stress resistance of mulberry trees can be enhanced, so that they can better adapt to the saline-alkali soil environment after formal planting.

[0053] S22, leveling the land: Clearing weeds, rocks and other obstacles on saline-alkali land and leveling the land surface; Clearing weeds, rocks and other obstacles on saline-alkali land and leveling the land surface can provide good basic conditions for the normal growth of mulberry trees.

[0054] S23, Transplanting Mulberry Trees: Transplanting the prepared mulberry trees to the saline-alkali land. The prepared mulberry trees are transplanted to the saline-alkali land for formal planting. After the initial improvement and preparation work, the mulberry trees can grow and develop better on the saline-alkali land, thereby increasing the protein content of the mulberry leaves.

[0055] From the above, we can see that before planting mulberry trees on saline-alkali land, preparatory cultivation should be carried out first. During the preparatory cultivation process, by simulating the actual saline-alkali land environment, adjusting the soil properties and adding some nutrient solutions suitable for growth, the mulberry trees can gradually adapt to the saline-alkali soil environment, thereby improving the stress resistance and adaptability of the mulberry trees, so that the mulberry trees can adapt to the saline-alkali soil in the early stages of growth, thereby promoting the growth and development of their root system. With a strong root system, the mulberry trees can be healthier in the later growth and development, can better absorb nutrients and water in the soil, and can increase the protein content of mulberry leaves.

[0056] Example 2: As shown in the attached Figure 3As shown: Based on the first embodiment,

[0057] The method further includes step S14 after step S13, applying a soil conditioner: pouring the soil conditioner into the deep-plowed saline-alkali land.

[0058] The spraying amount of soil conditioner is 10-30 kg per mu.

[0059] The preparation method of soil conditioner is as follows:

[0060] S141, prepare raw materials: 20% potassium silicate, 15% potassium dihydrogen phosphate, 10% humic acid, 5% magnesium silicate, and the balance water;

[0061] S142, gradually pouring potassium silicate into a mixing container while stirring to fully dissolve the potassium silicate;

[0062] S143, while stirring, gradually add potassium dihydrogen phosphate, humic acid, and magnesium silicate, and continue stirring to uniformly disperse them;

[0063] S144. Continue stirring and gradually add an appropriate amount of water. Stir until all ingredients in the formula are fully dissolved and mixed, and until the liquid is uniform. The ingredients in the soil conditioner can adjust the acidity and alkalinity of saline-alkali soils. Humic acid regulates soil pH, neutralizing the acidity or alkalinity of the soil and gradually neutralizing it. Potassium silicate and magnesium silicate neutralize salt and alkaline ions in the soil, reducing soil salinity and alkalinity.

[0064] Potassium dihydrogen phosphate provides phosphorus to mulberry trees, while potassium silicate and magnesium silicate provide potassium and magnesium to mulberry trees. These elements can increase the nutritional intake of mulberry trees and thus increase the protein content of mulberry leaves.

[0065] From the above, we can see that by applying soil conditioners in saline-alkali land, the soil pH can be adjusted, the soil structure can be improved, the nutrients required by mulberry trees can be provided, the growth and development of mulberry trees can be promoted, the protein content of mulberry leaves can be increased, and the stress resistance of mulberry trees can be enhanced, so that they can better adapt to the saline-alkali soil environment.

[0066] Example 3: As shown in the attached Figure 4 As shown: Based on the first embodiment,

[0067] In step S21, the method for preparing the cultivation includes the following steps:

[0068] S211, simulate saline-alkali land environment: take saline-alkali soil samples and prepare a culture medium that simulates saline-alkali soil. Soil containing a certain amount of saline-alkali components can be mixed with the culture medium to ensure that the simulated culture medium conforms to the characteristics of saline-alkali land;

[0069] S212, cultivating mulberry trees: cultivating mulberry trees in a simulated culture medium;

[0070] S213, adjusting spacing: adjusting the spacing between mulberry trees and the spacing between rows;

[0071] S214, gradually increase the salinity level: gradually increase the salinity level of the simulated saline-alkali land environment.

[0072] The method of gradually increasing the salinity level in step S214 is to gradually increase the salt concentration in the irrigation water or add a nutrient solution containing salt.

[0073] In step S23, the spacing between transplanted mulberry trees and the spacing between rows are the same as those in the preliminary cultivation in step S213.

[0074] The root system of mulberry trees is an important part of their growth and development. They play a vital role in soil water and nutrient absorption. The size of the plant spacing and row spacing will directly affect the distribution and growth of the mulberry tree root system. Appropriate plant spacing and row spacing can promote the distribution and growth of the mulberry tree root system and improve the mulberry tree's ability to absorb nutrients.

[0075] From the above, we can see that the root growth of mulberry trees will be affected by the spacing between plants and the spacing between rows. Appropriate spacing between plants and rows can promote the distribution and growth of the roots of mulberry trees. By adjusting the spacing between plants and rows of actual planting to the same as the spacing between plants and rows of prepared cultivation, mulberry leaves can quickly adapt to the saline-alkali land environment. In addition, the spacing between plants and rows of prepared cultivation are also determined after many adjustments. They are more reasonable parameters. When used in actual planting, they can better promote the growth and development of mulberry trees and achieve better results.

[0076] Example 4: As shown in the attached Figure 5 As shown: Based on the first embodiment,

[0077] A good drainage system can maintain appropriate soil moisture and prevent the roots of mulberry trees from being submerged in water for a long time. This can promote the development of the root system of mulberry trees, help the growth and absorption of nutrients by the roots, improve the adaptability of mulberry trees, prevent salt from accumulating around the roots of mulberry trees, reduce the absorption of salt by mulberry trees, and provide a more suitable growth environment.

[0078] In step S11, the method for constructing a drainage system includes the following steps:

[0079] S111, Determine the size of the drainage ditch: Determine the size of the drainage ditch based on the soil type and expected drainage volume of the saline-alkali land;

[0080] S112, digging drainage ditches; digging drainage ditches can increase the drainage area of the soil, improve the soil drainage capacity, speed up the removal of rainwater or irrigation water, avoid the accumulation of water in the soil, thereby reducing the concentration of soil salt and reducing the risk of soil salinization.

[0081] S113, adjust the slope of the drainage ditch.

[0082] From the above, we can see that by adjusting the slope of the drainage ditch, we can ensure that the accumulated water flows out of the saline-alkali land quickly, avoid water accumulation and water retention, prevent excess water from interacting with the salt in the soil, and reduce salt precipitation.

[0083] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
