采用随机区组设计,研究麦茬免耕覆秸精量播种、常规机械播种、人工小耧播种3种处理对种床土壤环境及大豆生长发育、产量构成因素的影响。结果表明,同常规机械播种、人工小耧播种相比,麦茬免耕覆秸精量播种能够优化种床土壤环境,促进幼苗的生长发育,改善产量构成因素,较常规机械播种、人工小耧播种分别增产96.1、180.3kg·hm-2。该技术在黄淮海地区具有广阔的应用前景。
Randomized block design was used to study the effects of precision sowing of no-tillage straw, conventional mechanical sowing and artificial sowing sowing on soil environment, growth and development and yield components of soybean. The results showed that compared with the conventional mechanical sowing and artificial sowing sowing, the precision sowing of no-tillage straw by wheat stubble could optimize the soil environment of the seedbed, promote the growth and development of the seedling, and improve the yield components. Compared with conventional mechanical sowing and artificial sowing sowing Respectively increase production 96.1,180.3kg · hm-2. The technology in the Huang-Huai-Hai region has broad application prospects.
