摘要
人工种植甘草是治沙工程中的内容之一 ,试验通过采取机械直播的方式种植甘草 ,研究了不同播种深度、灌溉水平、种植密度对出苗率、保苗率及生长量的影响。结果表明 ,在灌溉条件下 ,甘草播种量为 2 2 .5kg/hm2 ,密度 30万株 /hm2 ;在喷水条件下 ,喷水时数达 2 0h,灌溉总额约为 1 50 0 m3/hm2
Artificial propagation of GUF is a new item in preventing disaster by desert control project at Boertala prefecture. In this experiment GUF were planted using machine direct seeding. The effects of different seeding depth, irrigation fashion, density of plant on rate of emergence, rate of weeping a full stand of seedlings and growth quantity were studied. Technical measures of large area direct seeding propagation and nurture management were explored.
