在栽植密度一定且其它桑园管理措施一致的前提下，对春伐桑树不同技术处理与春季桑叶产质量的关系进行了调查。结果是栽植密度每667 m2桑地面积1000~1200株、N∶P2O5∶K2O=10∶5∶5的施肥比例，每667 m2桑地面积留条7500~8000根，低干无拳式树形的组合，可适当提高幼虫生命力、茧层率、良卵率及实用孵化率，显著提高桑叶产量、全茧量、茧层量和产卵量。

On the premise of same planting density and mulberry management measures, the influence of pruning with different processing technologies on the quality and quantity of mulberry leaves in spring was researched. The results showed that when the planting density was 1000~1200 trees in each 667 m2 field, the ratio of fertilization was N∶P2O5∶K2O=10∶5∶5, the remaining branch number was 7500~8000 in each 667 m2 field, the larval vitality, cocoon layer ratio, percentage of good eggs and the hatching rate were promoted, and the mulberry leaf yield, whole cocoon weight, cocoon shell weight and fecundity were promoted significantly.
