摘    要:对黑龙江省的3个主栽桑树品种秋雨、青龙、泰来进行无干栽植密度试验的结果表明,不同桑树品种有不同的适宜栽植密度。秋雨和青龙在60000株/hm2、泰来在75000株/hm2栽植密度下产叶量达到最高。桑树合理密植对桑叶质量影响不显著,但增加到60000~75000株/hm2后,随栽植密度的增加,养蚕质量也随之下降。栽植密度对养蚕质量各因素的影响,因桑树品种不同有差异。

关 键 词:桑树  寒地栽植  无干栽植  栽植密度

Effect of Planting Density of Ground-stemed Mulberry on Leaf Yield and Silkworm Cocoon Quality in Cold Region
AN Meijun. Effect of Planting Density of Ground-stemed Mulberry on Leaf Yield and Silkworm Cocoon Quality in Cold Region[J]. Acta Sericologica Sinica, 2005, 31(1): 88-90
Authors:AN Meijun
Abstract:The reasonable dense planting in mulberry was viable in such high altitude cold region as Heilongjiang Province. Different species contained different and suitable cultivation density. The influence of the reasonable dense plantation to the mulberry leaf quality did not show the significance. When the three experimental mulberry species have reached ~60 000 ~~75 000 plant/hm2 with the density, the leaf quality and cocoon quality were reduced with the increase of density, and the quality of keeping silkworms also reduced.
Keywords:Mulberry  Cold region plantation  Ground-stemed planting  Planting density
