种草的播种期不如一年生作物要求的那么严, 从冬季寄籽,早春顶凌一直到晚秋均可。我市常采用以下几种方式种草: (1)早春顶凌播种:早春大地复苏,刚能稳住耧动开始,可充分利用冻土消融的墒气,萌芽生长。既不与作物抢农时,争劳力,又容易捉苗, 成熟得早。但在长城沿线风沙区不宜采用,以免沙打切割草苗。

Sowing the grass is not as good as the requirements of annual crops demanding, from the winter seed, the top of the spring until late autumn can be. The city often adopt the following ways to grow grass: (1) early spring top Ling sowing: early spring resumption of the earth, just able to stabilize move start, you can make full use of frozen soil ablation of moisture, germination and growth. It is neither easy to fight labor nor easy to catch the seedlings when they are neither grab crops of crops nor rush to mature. However, sand and sand along the Great Wall should not be used in order to avoid sand cutting grass and seedlings.
