不同种植密度对先玉335性状的影响

为研究先玉335的栽培种植技术,进行了种植密度试验。密度为4000株/667m~2,产量最高,风干粒质量为1075.01kg/667m~2。产量排在第2～4位的处理分别是密度为5000、3000和6000株/667m~2的处理。并且4个处理之间经过方差分析,处理2、3与处理1、4间差异达到极显著水平;随着密度的增加,株高和穗位增高,空秆率、茎折率和根倒率增加。综上所述,先玉米335的最佳种植密度应为4000～5000株/667m~2为宜。

Planting Density on The First 335 Characters of Jade

To study the rst 335 Cornplant cultivation technology for the plant density test.Density of 4 000/667 m～2,the highest yield,dry weight is 1 075.01 kg/667 m～2.Production came in the rst 2-4 bit processing is a density of 5 000,respectively,3 000 and 6 000/667 m～2 of processing.After four treatments,and analysis of variance,treatment and processing of 1-4 and 2-3 very signi cant difference between levels,As the density increases,increased plant height and ear,empty plant rate,stem and root down rate of discount rates increased.In summary,Corn 335 of the best jade plant density should 4 000～5 000/667 m～2 appropriate.
