Technical Field

[0001] The invention belongs to the field of crop cultivation, in particular to a cultivation method for reducing salt accumulation in mulberry fruits. Background Art

[0002] Mulberries are a nutritious, uniquely flavored fruit with high economic value and market potential. However, they are sensitive to soil salinity. Excessive salinity can affect their growth and quality, and even kill them.

[0003] Traditional methods of improving saline soil often require large amounts of fresh water and chemical fertilizers, which consumes resources and pollutes the environment.

[0004] Therefore, a cultivation method that can reduce the salt accumulation in mulberry fruits is needed. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a cultivation method for reducing salt accumulation in mulberry fruits to solve the problems existing in the background technology.

[0006] A cultivation method for reducing salt accumulation in mulberry fruits comprises the following steps:

[0010] S4. Adjust soil structure and permeability and reduce obstacles through deep plowing, loosening, and mulching.

[0011] S5. Plant reeds and algae as salt-tolerant plants around or intercropping or use microbial restoration to carry out ecological management.

[0012] Preferably, before mulberry trees are planted, salt water is frozen and thawed to separate and gradually infiltrate salt and fresh water, and salt water is frozen and irrigated on saline-alkali land in winter.

[0013] Preferably, when planting mulberry trees, lignified hard branches with a diameter of 8 to 20 mm are selected and cut into 15 cm long cuttings. The upper incision is cut flat, 1 to 2 cm away from the bud bag, and the lower incision is cut into a 45-degree oblique cut, 5 mm away from the bud bag. 50 cuttings are bundled together at the upper and lower ends, and the lower ends are soaked in 50 mg / kg rooting powder solution for 3 to 4 hours, then fished out for use, and then the cuttings are buried in the soil at a 45-degree angle, covered with soil and compacted, with 100 to 150 plants per mu.

[0014] Preferably, during the water and salt regulation, irrigation is carried out every 7 to 10 days during the growth period of the mulberry trees, and the irrigation water quality is fresh water or brackish water with an electrical conductivity of less than 3dS / m;

[0015] During the fruiting period of mulberry, drip irrigation or sprinkler irrigation should be carried out every 5 to 7 days. The irrigation water quality should be fresh water or brackish water with an electrical conductivity of less than 3dS / m.

[0016] During the dormant period of mulberry trees, deep salt drainage irrigation is carried out, using a large amount of clean water to flush the soil and bring excess salt out of the soil surface. The irrigation water quality is fresh water with an electrical conductivity of less than 1dS / m.

BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 1 It is a flow chart of the specific method of the present invention. DETAILED DESCRIPTION

[0027] 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.

[0028] As attached Figure 1 As shown:

[0029] Embodiment: The present invention provides a cultivation method for reducing salt accumulation in mulberry fruits, comprising the following steps:

[0030] S1. Select mulberry varieties with strong salt tolerance and plant them on gentle slopes, using cuttings for planting. Gentle slope planting can take advantage of the terrain's height difference, increase sunlight and ventilation, reduce the occurrence of pests and diseases, and facilitate drainage and salt removal.

[0031] S2. According to the soil water and salt conditions, reasonable irrigation is carried out during the growth of mulberry trees to regulate water and salt;

[0032] S3. Apply organic fertilizer and biological fertilizer before planting mulberry trees and before or after irrigation to dilute the fertile layer;

[0033] S4. Adjust soil structure and permeability and reduce obstacles through deep plowing, loosening, and mulching.

[0034] S5. Plant reeds and algae as salt-tolerant plants around or intercropping or use microbial restoration to carry out ecological management.

[0035] Before fruit and mulberry planting, the freeze-thaw process of salty water is used to separate and gradually infiltrate fresh water. In winter, the frozen salty water is used to irrigate saline-alkali land. This helps ensure the emergence of spring crops and promotes the efficient use of brackish water and marginal salty water resources.

[0036] When planting mulberry trees, select lignified hardwood branches 8 to 20 mm in diameter and cut them into 15 cm long cuttings. Cut the upper incision flat, 1 to 2 cm from the bud, and the lower incision at a 45-degree angle, 5 mm from the bud. Bundle 50 cuttings from the upper and lower ends. Soak the lower ends in 50 mg / kg rooting powder for 3 to 4 hours, then remove and set aside. Then bury the cuttings in the soil at a 45-degree angle and cover with soil, compacting it firmly. Plant 100 to 150 plants per mu. This planting method can effectively increase the seedling success rate.

[0037] In water and salt regulation, during the growth period of mulberry, irrigation should be carried out every 7 to 10 days, with an irrigation volume of 300 to 400 cubic meters per mu each time. The irrigation water quality should be fresh water or brackish water with an electrical conductivity of less than 3dS / m.

[0038] During the fruiting period of mulberry, drip irrigation or sprinkler irrigation is carried out every 5 to 7 days, with an irrigation volume of 400 to 500 cubic meters per mu each time. The irrigation water quality should be fresh water or brackish water with an electrical conductivity of less than 3dS / m.

[0039] During the dormant period of mulberry trees, deep desalination irrigation is carried out. Large amounts of clean water are used to flush the soil, removing excess salt from the surface and reducing soil salinity. Each desalination irrigation volume is 800 to 1,000 cubic meters per mu (approximately 1.5 acres). Use fresh water with an electrical conductivity of less than 1 dS / m. By controlling the amount and quality of irrigation water, soil moisture and an appropriate salt concentration are maintained.

[0040] When diluting the fertile layer, before planting mulberry trees, improve the soil by applying 2000-3000 kg / mu of organic fertilizer and 50-100 kg / mu of biological agents, and deep plowing and loosening the soil to a depth of 30-40 cm.

[0041] During the growth period of mulberry, before or after each irrigation, apply 500-1000 kg / mu of organic fertilizer and 10-20 kg / mu of biological agents, and shallowly turn the soil 10-20 cm;

[0042] During the fruiting period of mulberry trees, apply 1000-1500 kg / mu of organic fertilizer and 20-30 kg / mu of biological agents before or after each irrigation, and shallowly plow and loosen the soil by 10-20 cm. This will increase the organic matter content and microbial activity in the soil surface, and enhance soil fertility and salt resistance.

[0043] Before planting mulberry trees, on the basis of applying organic fertilizer and biological fertilizer, deep plowing and loosening the soil 30 to 40 cm deep should be carried out, and plastic film or straw covering should be laid between the rows;

[0044] During the mulberry season and fruiting period, after applying organic and bio-fertilizers, shallowly plow the soil 10-20 cm deep and maintain mulch between rows. Deep plowing, loosening, and mulching improve soil structure and permeability, promote deep penetration and drainage of water and salt, and reduce surface salt content.

[0045] Before planting mulberry trees, reeds and salt-tolerant plants are planted around the orchard to form a wind and sand prevention belt, reducing the impact of wind and water erosion on the soil.

[0046] During the mulberry tree growth and fruiting season, algae-based microbial remediation plants are intercropped in orchards to absorb salt and organic matter from the soil, improving the soil environment. This ecological management can effectively improve the stability and self-regulation of the soil ecosystem and inhibit the development of soil salinization.
