Planting clover in an orchard can not only improve the orchard's ecological environment, beautify the orchard environment, but also cultivate fertility, improve soil, and facilitate the development of sightseeing agriculture; it can help improve the quality of fruit; it can develop orchard culture as a quality forage.
Planting time and method
Grass is usually grown between May and September. 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 sowing amount of clover is generally 1-1.5 kg/mu.
Sapling field management
Orchard application of grass cover technology after fertilization, take the method of furrow or fertilization, help to improve fertilizer efficiency. Fertilization in open trenches adopts a rotation system. Soil can be turned once in 4 years under a tree, which not only protects the grass cover, but also contributes to the change of soil structure. Acupuncture has better coverage of grass. Fertilizers are needed during the growing season. Once or twice a year, nitrogen fertilizer is mainly used, and spraying or foliar spraying methods are applied. Each year, 10-20 kg of nitrogen fertilizer is applied per mu. After clover 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. The cut grass can be used as breeding feed, and can also directly cover the tree disk as green manure.
Sown grass to improve fertilization
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. When turning over, the fruit trees should be turned slightly to avoid damaging the roots.
