1. Selection
Wind protection is not very strict with the soil requirements, but it should be selected from the land of high dryness and sunny land. The soil with loose, fertile, deep soil and well-drained sandy loam is most suitable. Clay, alfalfa, acid or heavy saline soil should not be planted.
2. Site preparation
The windbreak is a deep-rooted plant, and its root length can reach 50 to 70 centimeters in two years. Therefore, in the fall, it is required to deepen the land by more than 40 cm. In the early spring, the land should be leveled and polished, and the roots and debris should be picked up to create good basic conditions for wind-proof growth.
3. Fertilizer
In order to meet the needs of perennial windbreak growth and development on nutrient composition, base fertilizer must be applied, and 3,000 to 4,000 kilograms of high-quality farmyard fertilizer should be applied per mu, and superphosphate 20 to 30 kilograms or diammonium phosphate 8 to 10 kilograms should be added. It is best to apply to the surface of the ground before the deep fall, and then turn into the plough. It should be administered before the site preparation. Fertilization should be uniform.
