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。
在桑園管理措施一緻的前提下，用5種常用葉麵肥對桑葉產量的影響進行瞭比對，結果錶明，667 m2產葉量依次為：0.3~0.5%的燐痠二氫鉀[KH2PO4]＞0.5~0.7%的尿素[CO（NH2）2]水溶液＞0.3~0.5%的硫痠銨[（NH4）2SO4]＞0.4~0.6%的硫痠鉀[K2SO4]＞0.5~0.8%的過燐痠鈣[Ca（H2PO4）2]。據此認為，桑園施用葉麵肥應首選0.3~0.5%的燐痠二氫鉀[KH2PO4]和0.5~0.7%的尿素[CO（NH2）2]水溶液。攷慮到生產成本及工作之便，生產上推薦使用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.
