1、花前壮花。在抽穗至开花前15天,每株施尿素1—1.5公斤、过磷酸钙2公斤、氯化钾0.6—1公斤;叶面喷施生多素1000倍、58%瑞毒毒锰锌500—800倍的混合液,以提高荔枝花质和抗逆性。对于过密的花穗应进行疏花。留12—15厘米为宜。2、防止沤花和烧花。在荔枝盛花期可采用放蜂传粉和人工授粉。放蜂数为每亩荔枝园放蜂1—2群;人工授粉可喷荔枝授粉素来帮助授粉,并结合喷氧氯化铜500—800倍液防霜霉病。若遇阴雨无风天气时应及时进行人工摇花,抖落花朵上的水珠,防止沤花,以利于荔枝授精受粉;若遇高温干燥,则要向树冠和花
1, flowers before flowering. In heading 15 days before flowering, each plant urea 1-1.5 kg, superphosphate 2 kg, potassium chloride 0.6-1 kg; foliar spray 1000 times more prime prime, 58% Rui poison manganese zinc 500- 800 times the mixture to enhance the litchi flowers and resistance. For over-dense spikes should be thinning. Leave 12-15 cm is appropriate. 2, to prevent flax flowers and burning flowers. In litchi flowering can be used to put the bee pollination and artificial pollination. Put the number of bee litchi per parkes put bee 1-2 group; artificial pollination can spray litchi pollination to help pollination, and combined with copper oxychloride 500-800 times prevent downy mildew. In case of rainy and windy weather should be timely artificial flowers, shake off the drops of water on the flower, to prevent the flower, in favor of litchi insemination powder; In case of high temperature and dry, then to the crown and flowers
