玉米药剂灭草免中耕技术是在标准化整地的基础上实行机械精少量播种,同时深施入玉米生长全年需要的化肥,在播后苗前采用化学药剂封闭地表层,防止杂草生长,实现整个玉米生育期内不铲、不趟、不追肥(即免中耕)的一项先进农业技术。为此,论述了该技术的实施中应注意药剂、机具、时机3个方面的问题。
Maize herbicide-free mid-tillage technology is based on the standardization of land preparation and implementation of a small amount of mechanical sowing, while the deep application of corn fertilizer required throughout the year, after sowing seedlings sealed with chemical agents to prevent the growth of weeds, to achieve The entire corn growth period does not shovel, no trip, no dressing (that is, to avoid cultivating) an advanced agricultural technology. To this end, the article discusses the implementation of the technology should pay attention to pharmaceutical, equipment, timing, three aspects of the problem.
