Bagging fruit tree water and fertilizer management

After bagging, the fruit is mainly topdressed with phosphorus and potassium fertilizers. In order to reduce the content of soluble solids in the bagged fruit, it can be sprayed once in the end of June, 40 days before harvest and 20 days. Changle Yizhi (ie, rare earth), or June, July and 1 month before harvest, sprayed photosynthetic micro-fertilizer, farmer's and other micro-fertilizers, also have a certain effect on improving the soluble solid content of bagged fruit. Water must be watered during the period of fruit enlargement, before bag picking and before freezing, so that the soil water content is maintained at 70%-75% of the maximum water holding capacity in the field. Bagged fruit trees, try not to peel. In addition to the normal fertilizer management of bagged fruit trees, bagged fruit trees should further increase fertilizer management and leaf protection to maintain a robust tree potential and meet the needs of fruit growth. Planned bagging orchards should be applied to the base fertilizer in the first year of autumn, and appropriate addition of trace elements such as borax and zinc sulfate. Due to the decrease in calcium content in the fruit of bagging cultivation, it is easy to suffer from bitter pox disease, etc. It is best to spray 300-500 times of amino calcium or amino acid compound micro-fertilizer once a month from July to September. Water should be poured once every 3 to 5 days before bagging and 3 to 5 days before bagging to meet the moisture demand of the bagged fruit and prevent daily burning.
