July to September, citrus fruit swelled rapidly, the amount of hair root, a large number of pumping fall dormancy, the need for large amount of fertilizer, this time the root absorption of fertility, timely dressing to promote fruit enlargement, promote early autumn tip, improve fruit quality , To promote flower bud differentiation, to prevent the size of the results of a significant role. 1. fertilization period Zhuang fat generally applied in July to September, but should be based on age and tree potential may be. Full-fruit adult tree, strong manure should be applied in mid-July; early-stage young trees, should be applied from late July to early August, is conducive to strong fruit and promote early autumn tip: weak tree Mountain orange orchard should be early Shi, water
