Orchard grass cover technology is a soil management technology that can improve soil fertility, improve ecological environment, and improve fruit quality. Its main benefits are:
The first is to prevent or reduce soil erosion. After planting grass, the structure of soil aggregates was improved, and large-sized granules increased and the soil's cohesion increased. 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.
Orchard grass cover technology is mainly covered by artificial grass. The following aspects should be noted in artificial grass technology application:
Select suitable grasses. The selection of grass seeds should follow the cold-tolerant and drought-tolerant principles, the principle of resistance to negatives, the principle of resistance to trampling, the principle of fibrous roots, and the principle of ecological compatibility. Suitable for orchard species in the Beijing area are generally: leguminous species, such as white clover, alfalfa, sandawang, grass rhinoceros, Lotus root, etc.; grasses, such as D. arundinacea, Bromus, grassland premature Barnyardgrass, ryegrass, etc.; Cruciferae, eg.
Planting time and methods. Grass is usually planted in the spring, March-April, or autumn, September-October. It is suitable for seeding in spring and suitable for spreading in autumn. After flattening the land, water is irrigated once a week before sowing, so as to induce weed seeds to germinate and then spray the herbicides that are degraded in a short time, such as Gramoxone. After 10 days, they will be sprayed once and the remaining weeds will be weeded. Leach the agent and then sow the grass seeds. The seeding rate depends on grass species, ryegrass, fescue, etc. 2.5-3 kg/mu; white clover, alfalfa and other legumes 1-1.5 kg/mu.
Grass field management. Fertilizers are needed during the growth period of grasses. Once or twice a year, nitrogen fertilizers are mainly used, and spraying or foliar spraying is applied. Each year, 10-20 kg of nitrogen fertilizer is applied per acre. After the grass grows and grows, it must be cut in time according to the growth conditions. In the year of planting grass, it is best not to cut in the first few months. When grassroots is stable and is about 30 centimeters high, it will begin to castrate again. After the castration, the height of the grass is about 10 centimeters. The castration is carried out 3-5 times a year. The number of times the grass grows quickly is high, and vice versa.
Grass is overturned and fertilized. After 3-5 years of grass growth, the grass begins to age. At this time, it should be turned over in time and attention should be paid to turning the surface organic matter into the soil. Turn over the fruit tree and turn it slightly to avoid damaging the root.
