摘要
总结了不同种植密度对玉米品种的生理性状及产量和品质的影响,归纳了不同密度下,玉米品种的叶绿素含量、可溶性糖含量、可溶性蛋白含量等生理指标的变化情况,同时也对产量和品质的变化进行了总结。不同玉米品种对种植密度的反应不同,只有在适宜的种植密度下,玉米的生理指标都达到最适值,并且实现玉米群体产量的最大值,为玉米生产提供理论依据及技术参考。
The effects of different density on the physiological characteristics, yield and quality of maize were concluded. Variation of chlorophyll content, the soluble sugar content and the soluble protein content of maize varieties were also induced. Meanwhile, the yield and quality were summarized. The different maize varieties had the different reactions to the planting densities. Only under the suitable planting density, the maize physiological indices achieved optimum value and realized the maximum value of corn yield, which provided a theoretical basis and technical reference for maize production.
