我省稻茬免耕种麦于80年代开始推广应用,1986年以来稳定在2000万亩以上,占麦田总面积50％左右,占稻茬麦面积的80％左右。多年来的实践证明,少(免)耕种麦与常规耕翻播种相比,具有早发壮苗,穗多产量高,省工节本,经济效益高等优点,因此这项技术受到广大农民的欢迎。但目前有些地方,由于播种方法不当和配套措施不完善,影响单产的提高。本文拟通过对当前所应用的5种不同少(免)耕种麦方法的优缺点进行评价,并结合各地区特点选优应用,以期进一步发挥少(免)耕种麦的优势。
The no-tillage crop of rice crop in our province began to be popularized and applied in the 1980s. Since 1986, it has been stable at more than 20 million mu, accounting for about 50% of the total wheat field area, accounting for about 80% of the rice crop area. Many years of practice have proved that this technique is welcomed by the majority of peasants because it has the advantages of early seedling emergence, high spike yield, saving the cost of production and economy, and higher economic benefits compared with conventional tillage sowing. . However, in some places, due to improper sowing methods and imperfect supporting measures, the improvement of yield will be affected. This paper intends to evaluate the advantages and disadvantages of the five currently used methods for cultivation of less and less cultivated wheat, and to optimize the application of less (free) cultivated wheat based on the characteristics of each area.
