For the planting and management of Sakyamuni fruit, the key points of fertilization is the top priority, so how to apply fertilizer to Sakyamuni fruit? Let's get to know it.

1. Key points of fertilization for young trees

Fertilization for young trees is different from that for fruiting trees. Generally speaking, before young trees are planted, sufficient basal fertilizer should be applied to ensure the growth of young trees. The base fertilizer is generally applied 2-3 months before planting, and the application of the base fertilizer can be carried out with soil preparation and trench digging. First, the planting ditch is dug according to a certain plant row spacing on the planting ground, and then the base fertilizer is applied in the ditch to cover the soil again, so as to avoid direct contact between the young tree root system and the fertilizer, so as not to cause root burns, and is also conducive to root absorption. Fertilizer is recommended to choose green manure or mature farm manure, generally about 10-20 kg per plant, in addition, 1 kg of phosphate fertilizer is applied to ensure seedling growth. In addition, the disease resistance of young trees is weak, so in addition to adequate base fertilizer, appropriate lime should be added to reduce the occurrence of diseases. Young trees should be fertilized many times, generally speaking, appropriate topdressing should be carried out every time the new shoots germinate.

II. Fertilization for adult trees

1. Base fertilizer

For adult trees, it is also necessary to ensure adequate intake of base fertilizer, so that the case can ensure the growth of the tree and promote fruit hanging. Generally, base fertilizer can be applied in spring or autumn, that is, in February or October. The amount of base fertilizer should be determined according to the growth, age and yield of adult trees. generally, trees with older trees and high yields should increase the application of base fertilizer, for example, if they do not produce 100 jin of fruit, they need to consume about 20 jin of high-quality manure. Only in this way can we give full play to the effect of base fertilizer.

2. Topdressing

Topdressing for adult trees generally needs topdressing 5-6 times a year, which is roughly divided into flowering fertilizer, fruit fertilizer and fruit picking fertilizer, in which the main purpose of flowering fertilizer is to promote flowers and protect flowers, and the time is about 2-3 months. Because Sakya fruit flowers have high requirements for phosphorus and potassium fertilizer, it is recommended to choose a compound fertilizer with uniform nutrition. Expired topdressing should be specific to different periods, generally need topdressing after flower fade, and compound fertilizer is also recommended; the last topdressing is in the fruit harvest period, at the end of September, each plant needs to apply 5-10 kg of farm manure to promote the recovery of tree potential.
