摘要
为了指导玉米生产,研究了不同行距和播期对玉米生长特性的影响。结果表明:不同行距和播期对籽粒产量及其构成因素均有显著影响,50 cm窄行产量最高,55 cm行距次之,60 cm产量最低;随播种期的推迟,株高、穗位高呈下降趋势,籽粒重量呈降低趋势。
In order to guide the production of maize, effect of row spacing and sowing time on the growth characteristics of Maize were researched. The results showed that different row spacing had a significant influence on wheat yield and its components ,suitable row spacing was 50 cm ,its yield was the highest, 55 cm was second,yield of 60 cm was minimum. With the seeding time delayed plant height and ear height showed a trend of decrease. Grain weight showed a trend of decrease.
