| 摘 要： | 通过桑树冬、春不同施肥量对桑树春季生产性能的影响研究。结果表明：冬季施肥量充足的情况下，可大幅度减少春肥或不施春肥，桑树春季经济性状指标及产叶量仍然达到较高水平。每株桑树冬施1．5kg蚕沙加春施23gN、13.8gP2O5、9．2gK2O增值最高；冬施1．5kg蚕沙，春季不施肥，对桑树春叶产量影响不大。

| Abstract: | The fertilization experiments in winter and spring were conducted for revealing their effects on mulberry leaves growth in the field in spring. The results were listed as follows. Under abundant fertilizing in winter, the economic character target and yield of mulberry leaves could reach the higher level in spring, although fertilizing were reduced at large scale or no fertilizing in spring. The highest yield of mulberry leaves could be obtained when the mulberry tree was fertilized with 1.5 kg silkworm feces in winter plus 23 g N,13.8 g P 2O 5,9.2 g K 2O in spring. The highest benefit was obtained when the mulberry tree was fertilized with 1.5 kg silkworm feces in winter and on fertilizing in spring. |
