Benefits of garden restoration
First, maintain drought resistance
After all kinds of weeds cover the whole orchard, the evaporation of soil moisture can be reduced. When the growth rate is too high, the number of tree supports covered by lawn mowers decreases, which can maintain drought resistance.
2. Increase the content of soil organic matter
Green plants, such as soy sauce, contain a lot of organic matter. Plant natural raw materials every year to increase the density and thickness of various grasses. Real death or artificial cutting is adopted to increase the content of organic matter in the soil, and fertilizer is used to reduce soil nodulation and prevent soil acidification to make high-quality apples.
3. Reduce the temperature of the orchard and adjust the microclimate of the park.
The heat of green plants such as soil, water, fertilizer, air and grass in soil can be increased mechanically, which can improve the air humidity of orchard. When the temperature is high in summer, you will feel cool in the orchard, which is beneficial to the growth and development of fruit trees and can reduce the occurrence of surgical diseases.
4. Adjust the soil moisture and particle structure to resist floods and injuries.
The growth of all kinds of weeds and the secretion of roots and residues promote soil microorganisms, contribute to the form and structure of soil, increase effective pores, reduce the soil capacity of orchard, increase water seepage and water holding capacity, especially in rainy season, tsaoko orchard can reduce oligonucleotide level.
In the orchard, there are two main methods, the grassland method.
1 artificial grass method
The main types of good grass commonly used in artificial grassland are alfalfa, clover, clover, white clover, hairy, Tianjin, Dalmao, ryegrass, mouse grass, octoploid grass and so on. Good grass planted by hand can be spread on fruit trees or used as grass after grazing. Pay attention to the rusty organic fertilizer in the park in front of the lawn. At the end of March and the beginning of April, autumn planting is more suitable for mid-August to mid-September. Be sure to water it in advance or water it slightly in the rain.
2 natural grass, ovariectomized
Orchard to keep fruit trees in hematology for more than one year, eliminate weeds, herbs and other grasses; 60 cm around the fruit tree, remove 60 cm. Natural grassland is suitable for large-scale popularization in China, which is one of the measures to save management.
It should be pointed out that when the grass seeds left by artificial planting or natural primitive gentle selection grow to a certain height, it takes time to cut the landscape to prevent the growth of fruit trees. Under normal circumstances, when the good grass in the orchard is 30-40 cm away from the plant, it needs to be released, and the stubble should be cut about 5-8 cm, and it should be cut twice a year according to the grass potential to reduce it. Weeds are suggested to be evenly covered under trees, or to collect compost in parks.
