高寒阴湿山区翅果油树引种育苗与造林试验

Seedling and forestation tests of Elaeagnus mollis at high cold and damp mountains

为了丰富高寒阴湿山区育种与造林所需的种质资源,引进翅果油树的插条、种根和种子,采用地膜覆盖插根育苗、播种育苗和插条育苗等育苗技术,进行了育苗试验。结果表明:采用地膜覆盖插根育苗技术的育苗效果高于播种育苗和插条育苗。还引进2年生翅果油树的截干苗木,分别采用与高杆和低杆农作物间作的方法,进行了间作造林对比试验。结果表明:当年造林且与高杆农作物间作造林的效果比与低杆农作物间作造林的好。育苗与造林试验结果均表明了翅果油树可适用于高寒阴湿山区中育苗和栽植。

In order to enrich germplasm resources of breeding and forestation at high cold and damp mountains,seedling test of Elaeagnus mollis was carried out,taking cuttings,root,seed,root as materials,by mulching film covering root cuttings,sowing breeding and cuttings breeding techniques.Forestation test was carried out,taking 2-year-old cutting trees as materials,by high and low stalked crop intercropping.The results showed that the effect of film covering root cuttings was better than sowing breeding and cuttings breeding,and the effect of high pole crop intercropping was better than low stalked crop intercropping.E.mollis Diels was suitable for cultivation at high cold and damp mountains.
