摘要
在桑园管理措施一致的前提下，用5种常用叶面肥对桑叶产量的影响进行了比对，结果表明，667 m2产叶量依次为：0.3-0.5%的磷酸二氢钾[KH2PO4]＞0.5-0.7%的尿素[CO（NH2）2]水溶液＞0.3-0.5%的硫酸铵[（NH4）2SO4]＞0.4-0.6%的硫酸钾[K2SO4]＞0.5-0.8%的过磷酸钙[Ca（H2PO4）2]。据此认为，桑园施用叶面肥应首选0.3-0.5%的磷酸二氢钾[KH2PO4]和0.5-0.7%的尿素[CO（NH2）2]水溶液。考虑到生产成本及工作之便，生产上推荐使用0.5-0.7%的尿素[CO（NH2）2]水溶液。
Under the same premise of mulberry field management measure, effects 5 kinds of foliar fertilizer on yield of mulberry leaf were compared. The results showed that the yield of mulberry leaf in each 667 m2 were 0.3-0.5%KH2PO4〉0.5-0.7% CO（NH2）2〉0.3-0.5% （NH4）2SO4〉0.4-0.6% K2SO4〉0.5-0.8% Ca（H2PO4）2. It indicated that 0.3-0.5% KH2PO4 and 0.5-0.7% CO（NH2）2 would be preferred as mulberry leaf fertilizer. Considering the cost of production and work, 0.5-0.7%CO（NH2）2 was recommended for the use of production.
