所谓催短芽,即把种子用温水浸透后捞出,置适温处催芽,至幼根刚突破种皮时为度.直接播种就是将催短芽的种子和不催芽的种子一样看待,正常播种.实践证明,催短芽直接播种的玉米、高粱种子,只要土壤墒情、温度适宜,即能很快出苗,一般可比干种下地早出苗2—3天,而且出苗整齐.即使土壤墒情不好,播种后种子落干,遇雨后仍能正常出苗. The so-called short buds, that is, the seeds soaked with warm water after the fish out, set suitable temperature sprout, when the young roots just break the seed coat when the degree of direct sowing is to shorten the seeds and non-sprouting seed see the same seeds, normal Practice has proved that direct sowing buds of corn, sorghum seeds sowing, as long as the soil moisture, temperature appropriate, that is, can emerge sooner, generally 2-3 days earlier than the dry seedling emergence, and emergence of neat, even if the soil moisture is not good After sowing, the seeds fall dry and can still germinate normally after the rain.
