中文摘要:
      旨在掌握适宜河南省各地夏播种植的机收玉米品种‘桥玉8号’的最佳种植密度,本研究采用大田单因素随机区组试验设计,分析了不同种植密度对其叶面积指数、倒伏率、抗倒能力、机收指标和产量的影响。结果表明‘桥玉8号’整个生育期叶面积指数呈先增后减的单峰变化趋势,在抽雄期达到峰值。随着种植密度的增加,倒伏率升高,地上第3节间的茎粗变细、穿刺强度下降,机收籽粒的落籽率、籽粒破碎率也随之增加,而杂质率无明显变化规律。从产量、倒伏率、机收含水量和机收指标方面分析来看,‘桥玉8号’适宜的种植密度为8.25~9.00万株/hm2。本研究结果可为适宜机收玉米品种高产栽培提供合理的种植密度和良好的机收质量依据。
英文摘要:
      The research aimed to master the optimum planting density of the Maize variety ‘Qiaoyu 8’ which suitable for summer maize mechanized harvest in Henan province, the single-factor randomized trial was designed in this study, analyzed the effects on the leaf area index, the lodging rate, the lodging resistance, the mechanized harvest indicators and the yield in different density treatments. The results showed that the leaf area index increased first and then decreased in the whole growth period, and reached the peak value in the tassel period. With the increase of planting density, the lodging rates increased, stem diameter of the 3rd internode above ground was thinner and the rind penetration strength of the 3rd internode above ground decreased, the grain loss rate and grain crushing rate were increased too, while the impurity had no obvious change. From analyzing the production, grain moisture content, lodging rate, mechanized harvest indicators, the suitable density of ‘Qiaoyu 8’ should be 8.25-9.00×104 plants hm-2.The results would provide reference for reasonable planting density and good quality mechanized harvesting for high-yield cultivation of maize varieties.
