桑科木本饲料在新疆引种试验研究

RESEARCH ON INTRODUCTION OF THREE KINDS OF WOODY MORA CEAE FEED PL ANTED IN NORTH XINJIANG

本试验引进了雅津蛋白桑、速生多倍体高蛋白桑和构树三种木本植物在新疆北疆三个生态区进行了两年试验。通过耐盐碱试验以及越冬性、病虫害、耐寒性、叶面积大小、生长速度、光量子和产量等性状调查和测定,得出结论:雅津蛋白桑适合在北疆改善环境快速造林使用。速生多倍体高蛋白桑适合做.饲草,可以在北疆推广种植。构树不适合在北疆种植。

Three woody plants of Yajin protein mulberry,fast-growing polyploid high protein mulbery and Broussonetia papyrifera were introduced into the experiment for two years in three ecological regions of Northern Xinjiang.Through the salt and alkali tolerance test,variety comparison test,and the investigation and deternination of overw intering,diseases and insect pests,cold tolerance,leaf area size,growth rate and light quantum,the conclusion is that Yajn protein mulberry is suitable for rapid afrestation in Northern Xinjiang.The fast-grow-ing polyploid with high protein is suitable for forage and can be planted in Northern Xinjiang.Broussonetia pa-pyrifera is not suitable for planting in Northern Xinjiang.
