Orchard covered with grass to improve soil fertility

The first is to prevent or reduce soil erosion. After planting grass, the structure of soil aggregates is improved, and the large-sized particles increase, and the "cohesion" of the soil increases.

The second is to improve the soil and improve soil fertility. Orchard growing grass and burying it into soil at the right time can improve soil organic matter, improve soil structure, increase soil nutrients, and create a nutrient-rich, loose porous root environment for the growth of fruit tree roots.

The third is to promote the ecological balance of orchards. The number and population of parasitic natural enemies, such as predatory natural enemies and parasitoids, such as ladybirds, grasshoppers, grasshoppers, and spiders, have increased. The ability to use natural enemies to control pests and their occurrence has increased significantly.

The fourth is to optimize the orchard's microclimate. Grass planting in orchard can make the temperature of the soil change day and night and the extent of seasonal changes, which is conducive to the root growth of fruit trees and the absorption of nutrients.

The fifth is to inhibit the growth of weeds. Red, white clover, Bahia grass, ryegrass and other competitive, can effectively inhibit the growth of a variety of weeds after the ping, inhibition rate was 55% -70%. Sixth, it is to promote the development of tourism agriculture. With the development of tourism and leisure agriculture, farmhouse music is deeply loved by consumers. When the fruit trees bloom in spring, the grass orchard is already green and adds a layer of beauty. When the fruit is full of branches, the orchard that covers the white clover is covered with red and white flowers. It seems like the summer night is full of stars and makes people feel relaxed and happy; Thanks to the fruit, the orchard orchard is still green, making the fruit industry tourism season less prosperous and the season more prosperous.
