杜仲种子萌发试验与分析

Studies on Seed Germination of Eucommia ulmoides

使用兰州引种杜仲所产带果皮种子,进行萌发试验。结果表明,兰州栽培杜仲所产种子具有发芽能力,可以用来播种育苗,但发芽率较低;果皮是限制杜仲种子发芽的关键因素。讨论认为,在一些土壤水分条件较好的立地上,可以在入冬前采集杜仲种子,水选法优选后采用微圃植树法造林,以降低造林成本,加快造林进程。

The germination test of Eucommia ulmoides seed was carried out by using introduced seeds in Lanzhou, and the seeds with peel. The results show that, Eucommia ulmoides is cultivated in Lanzhou has the ability to germinate, and can be seeded, but the germination rate is low; The skin is the key factor that restricts the germination of Eucommia ulmoides. To discuss that in some good site on the soil moisture conditions, can collect seeds of Eucommia ulmoides before the winter, and use the method of invading water to select good seeds to afforestation with the miniature nursery method, this method can reduce afforestation cost and accelerate forestation process.
