祁连圆柏不同催芽方法研究

Study on Different Pregermination Method of Sabina przewalskii

本文利用羊圈内混羊粪层积及露天埋藏2种不同的催芽方法,研究了在春、秋2季不同催芽方法下的出苗率。经对比试验发现,4种组合中羊圈内混羊粪层积催芽且在春季播种的效果最好,密度达到了176株/m2;其次是羊圈内混羊粪层积催芽秋季播种的较好,密度达到了147株/m2;露天埋藏催芽处理种子后在春、秋2季播种育苗的效果都不显著。

This article take the two different pregermination method and in the spring and autumn sowing,one way is to use sheep manure stratification and the another way is to outdoor buried.The results show that the method which used sheep manure stratification and sowing in spring is the best and the density is 176 plants/m2,the density of sowing in autumn is 147 plants/m2.The effect of outdoor buried is not significant.
