要实现荔枝连年丰产稳产,必须注重产后的管理工作:一、及时施肥,恢复树势。荔枝树开花结果后,已消耗完树体内积累的营养.并且从土壤中带走大量的养分。为了使荔枝树恢复树势,以保证下年开花结果,早中熟种在采果后半个月至一个月、晚熟种在采果前10～15天施肥,这次速效肥与迟效肥配合施用,肥量约占全年施肥量的:氮肥30%、钾肥20%,磷肥20—25%。全年施肥量以结50公斤果的植株计:氮肥(折合尿素)2～2.5公斤,磷(折合普钙)2.5公斤,钾肥(折合氯化钾)2.5～3.0公斤。二、及时修剪.促进抽发夏秋梢。荔枝采果后及时剪去果柄、落花落果枝及冠内膛的细弱枝、交叉枝、枯枝、病
To achieve litchi crop yield in successive years, we must pay attention to post-natal management: First, timely fertilization and recovery of tree vigor. After the flowering fruit of the lychee tree has consumed the accumulated nutrients in the tree, it takes away a lot of nutrients from the soil. In order to restore the litchi tree vigor, in order to ensure the flowering next year, early middle and late mature species in the second half months after picking fruit, late maturing 10-15 days before picking fruit fertilizer, the quick-acting fertilizer and delayed fertilizer With the application, the amount of fertilizer about the annual amount of fertilizer: 30% nitrogen, potassium 20%, phosphorus 20-25%. The annual amount of fertilizer to knot 50 kg of fruit plants: nitrogen fertilizer (equivalent to urea) 2 ~ 2.5 kg, phosphorus (equivalent to calcium) 2.5 kg, potassium (equivalent to potassium chloride) 2.5 to 3.0 kg. Second, timely pruning. Promote the summer hair tip pumping. Litchi fruit cut off after a timely cut fruit stalks, falling off the fruit and the crown of the fine branches, cross branches, dead branches, disease
