桑树春季育苗过去采用干种子直播,这种方法占地多,出苗差。近两年来,不少地方采用塑料薄膜两段育桑苗,提高了出苗率,但这种办法耗用薄膜多,成本高。1982年我们在华封公社试验成功了应用“地坑”催芽播种,育桑苗600床,收到了出苗多,成本低的效果。 Mulberry spring nursery past the use of dry seeds live, this method covers an area of ​​more, poor emergence. In the past two years, two places of plastic film have been used to raise the germination rate in many places, but this method consumes many films and costs are high. In 1982, we succeeded in applying the “pit” germination sowing test in Huafeng commune to cultivate 600 beds of mulberry seedlings and received the effect of more emergence and low cost.
