我区小麦播种面积历年约占总播种面积的50％左右。麦茬中三分之一播种大田作物,其余三分之二是重茬麦。如何提高重茬麦单产是生产上急待解决的问题。过去重茬小麦一直沿用耕翻方法播种。我们在少耕法研究中,采用耙麦茬播麦法来代替连年耕翻。经二年研究证明:耙茬播种不仅能克服不利的自然条件,而且成本低经济效益高。一、试验设计在大豆——小麦——小麦轮作形式下采
My area of wheat sown area over the years accounted for about 50% of the total sown area. One-third of the stubble crop is planted with field crops and the remaining two-thirds are cropped wheat. How to improve cropping wheat yield is an urgent solution to the problem of production. Pasture wheat has been planted with tillage. In the study of less tillage, we used the method of raking wheat stubble instead of plowing in successive years. After two years of research shows that: rake crop sowing not only to overcome unfavorable natural conditions, but also low cost and high economic efficiency. First, the experimental design in the soybean - wheat - wheat crop under mining
