栽培措施对湖桑生长和桑叶产量的影响*

 采用随机区组试验设计，在云南省鹤庆县于2001年设置了反应桑树人工栽植和经营管理各主要环节的试验林，研究了不同栽培措施对湖桑生长和桑叶产量的影响。结果表明，不同栽植密度对湖桑的生长和单株桑叶产量有一定影响，但是差异没有达到显著水平；间作方式对湖桑的树高、地径、分枝长和桑叶产量的差异达到显著水平(P＜0.05)；施肥、抚育管理对湖桑的生长和单株桑叶产量有明显影响，达到极显著水平(P＜001)。应用于生产，可指导并促进当地桑树速生丰产。

Effect of Cultivation Measures on Growth and Leaf Yield of Lake Mulberry

A randomized block experimental design was used to study the effect of different cultivation measures on the growth and leaf yield of lake mulberry, a series of lake mulberry manual plant and management experiment were established in Heqing County of Yunnan Province since January 2000. The results showed that different altitude, soil type, fertilization, tending and management had more obvious effect on the growth and fresh leaf yield per plant of lake mulberry. Their variances of different soil type, fertilization, tending management on the tree height, base diameter, branching length and fresh leaf yield per plant of lake mulberry wene extremely remarkable(P＜0.01), different altitude on the tree height, base diameter, branching length and fresh leaf yield per plant of lake mulberry were remarkable(P＜0.05), plantation density on the tree height, base diameter, branching length and fresh leaf yield per plant of lake mulberry were not remarkable.
