Due to the rapid growth of roots and large numbers of hairy roots in autumn, the autumn roots are easily healed by fertilization and are conducive to multiple rooting. Fertilizer can be used to fertilize the nutrient, increase the nutrient reserve before winter, and improve the cold resistance of the tree. Fruit quality and yield. Therefore, we should pay attention to fertilization in autumn and lay a good foundation for the high yield of cherry in the coming year.
Fertilization methods: 1. Strip groove application. Suitable for base fertilizer. Trenches are applied on the outer edges of the crowns corresponding to the tree body. Each year, one direction is used alternately. When basal fertilization is applied in autumn, the ditch is larger, generally about 30 to 40 cm. 2. Ring ditch is applied. An annular groove is dug around the circumference of the crown, and the depth, width and width of the groove are the same. This method is mostly suitable for young trees with a small range of root distribution. 3. Application. Spread the fertilizer evenly under the tree and then plunge into the soil to a depth of about 20 cm. However, due to shallow application, it often leads to the floating of the root system and reduces the stress resistance of the root system. It should be conducted every other year with the radiation groove method.
Fertilizer type and quantity: The types of basal fertilization in autumn season include farmyard manure and appropriate amounts of nitrogen, phosphorus, and potassium compound fertilizers, etc. The farm manure mainly consists of fully fermented pig manure, cow manure and sheep manure. During the fruit period, the tree has 3 cubic meters of sheep manure per mu, 5 cubic meters of pig manure and cow dung, and 1,000 kilograms of compound fertilizer. At the same time according to the tree's vigor, tree size, the amount of results, there are some results of soil testing formula to apply some fruit tree compound fertilizer, and timely addition of trace elements.
