Nutritional supplementation of the tree from fertilization in the soil and fertilization outside the root:
Â
1. Foliar fertilizer: After a fruit harvest in the orchard, the temperature and ground temperature are still high, which is conducive to the growth and development of fruit trees. The roots enter the third growth peak, and the nutrients produced by the leaves are roots, stems and branches. Transfer and accumulation. Spraying foliar fertilizer can quickly replenish the nutrients that the tree body consumes a lot due to the result, and restore the tree potential as soon as possible. Apple spraying foliar fertilizer, can use 0.3% ~ 0.8% of urine or 0.2% ~ 0.3% potassium dihydrogen phosphate solution + new high fat film, spray every 10 to 15 days, spraying time to no wind, air The weather with high humidity is good, and avoid around noon.
Â
2. Early application of base fertilizer: After harvesting fruit in early-maturing varieties, late-maturing varieties are applied before fruit picking, and it is best to maintain green leaves for 1 to 2 months after application. The type of fertilization is mainly organic fertilizer, and a small amount of chemical fertilizer is applied. The amount of organic fertilizer: the medium and low-yield orchard uses the pounds of fruit and fertilizer, and the high-yield and high-yield orchard uses 1.5 to 2 kg of fertilizer. Before the application of organic fertilizer, it should be fermented by decomposing to prevent the feces from burning. Fertilizers need to be combined with nitrogen, phosphorus and potassium fertilizers, and targeted application of trace element fertilizers, such as high-concentration compound fertilizers.
Â
Fruit trees are susceptible to freezing damage and need to be protected against cold and frost:
Â
1. Pouring the frozen water before freezing: It can increase the soil water content and increase the winter ground temperature. Watering is also one of the ways to prevent cold and frost.
Â
2. Coating protection agent: The winter climate is dry and the soil should be kept warm and moisturized. Under normal circumstances, the mulch film is covered to protect the ground temperature and the general garden spray protects the tree to protect the tree body for winter.
