October Orchard Autumn Shiji Fei was

Autumn is the third growth peak of the fruit tree root system, with large root growth and strong absorptive capacity; wound roots are easy to heal, and new roots can be promoted to increase the absorption area. Its absorption of synthetic nutrients, mainly stored in the tree, directly affect the fruit tree's resistance to disease, antifreeze. Therefore, after fruit harvest, farmers should pay attention to the application of basal fertilizer and the management of weeds, and should be completed sooner rather than later.

Fertilizer mainly consists of farmyard manure such as chicken manure, sheep manure, cow dung, etc., full-fledged farmyard manure is applied at 5000 to 6,000 kg per acre in the orchard, and crushed straw is properly applied; chemical fertilizer is applied 15-6 -10 type ternary compound fertilizer is appropriate, it is not suitable to apply high nitrogen, high potassium, high phosphorus compound fertilizer. At the same time pay attention to the supplement of calcium, zinc, iron, boron and other trace elements, so that the combination of improved soil and feeding delay and quick effect.

Fertilization uses 2 years of deep application and 1 year of shallow application. Deeply dig a ring-shaped groove or radial groove. The groove width is 25-30 cm and the depth is 50-60 cm. The position of the ditch should be staggered every year. After fertilizing, the soil should be covered with water, and the frozen water should be poured before freezing.
