毛白杨基灌育苗法可节省种条,获得高产,苗木质量优良。但这种育苗方法种条必须经过越冬贮藏,不仅费工,而且贮藏的种条春季常在坑内发芽而被废弃。另外在种条入出窖坑及运输过程中,易使芽子受损而影响产苗量。为此,我们从1985年开始采取随剪随埋的方法育苗,取得很好效果,平均亩产4200株左右,合格苗木在75%以上。 一、圃地选择及施肥做床 育苗地应选在地势平坦,有灌溉条件的沙壤或壤土地上,结合深耕,每亩施有机肥
Populus germplasm irrigation method can save seed, get high yield, excellent quality of seedlings. However, this seedling breeding methods must be overwintered storage of species, not only laborious, but also the storage of seed in the spring often germination and was abandoned. In addition to the cellar into the pit and transport in the process, easy to damage buds affect the production of seedlings. To this end, we started to adopt the method of cutting and burial along with seedling breeding in 1985 and achieved very good results. The average yield per mu is about 4,200, and qualified seedlings are over 75%. First, the choice of land and fertilization bed bed nursery should be selected in the flat, irrigated sand or loam soil conditions, combined with deep plowing, organic fertilizer per acre
