摘要
设置不同的种植密度,研究洛玉8号的种植密度与产量以及产量构成因素的关系。结果表明:种植密度对其株高的影响最大,其次是千粒重、行粒数,对穗长和穗行数的影响不显著。种植密度是影响玉米产量的关键因素,豫西及其类似地区的洛玉8号高产种植密度不宜超过78755株/hm2,最佳生产种植密度为70000~75000株/hm2。
The relationship among planting density,maize yield and yield components of Luoyu No.8 was studied.The results revealed that planting density has greatest influence on plant height,then significant influence on 1000-grains weight and grain number per row,but non-significantly influence on ear length and ear row number.Planting density is the key factor to influence yield of maize,which means the best planting density of Luoyu No.8 in Yuxi district and other similar areas is not over 78 755 shoots/hm2.
