摘要:

为了筛选出‘金刚青贮50’和‘铁研53’2个粮饲兼用青贮玉米品种在陕西省榆林市榆阳区的适宜种植密度,本试验对2个品种分别设置了52500、60000、67500、75000株/hm2等4个种植密度,对每个品种在不同密度下的农艺性状、产量、营养成分含量、叶重占比、穗重占比进行了比较。结果表明:随着种植密度的增加,2个品种的总产草量以及总营养量呈上升趋势,且在75000株/hm2时最高。因此适宜的种植密度都为75000株/hm2

Abstract:

In order to screen out the suitable planting density for two grain and forage silage maize varieties, ‘Jingang silage 50’and ‘Tieyan 53’, in Yuyang District, Yulin City, Shaanxi Province, 4 planting densities of 52500, 60000, 67500 and 75000 plants per hm2 were set in this experiment for the two varieties respectively. The agronomic characters, yield, nutrient content, ratio of leaf weight and ratio of panicle weight of each variety under different densities were compared. The results showed that, with the increase of the planting density, the total grass yield and total nutrient content of the two varieties showed an increasing trend, and reached the highest value at 75000 plants per hm2. Therefore, the suitable planting density is 75000 plants per hm2.

Key words: silage maize, planting density, agronomic characters, yield, quality
