Longan trees before and after the fruit picking orchard management, is to ensure long-term high and stable longan, and the harvest for the coming year to overcome the size of year, and lay a good foundation. (A) Shi Zhuang Zhuangguang Zhoushuo fat. “Dazu - Liqiu” is the fierce longan longan tree fruit, the fruit swelled rapidly, autumn shoots began to sprout. Therefore, a reasonable fertilization can reduce fruit drop, increase the fruit, promote the growth of summer tip enrichment, early fall shoots well. Before and after flowering in time to topdressing fertilizers to nitrogen flower, leaves, to phosphorus to promote, to calcium boron steady fruit. The amount of fertilizer according to the size of the tree, the general plant manure excreta 50 to 100 kg, 1.5 kg of superphosphate, urea 0.5 kg, chlorination
