为研究木里县适宜的玉米种植密度,开展了田间试验.采用'西抗18'玉米品种,设置4.50万、5.25万、6.00万、6.75万、7.50万株/hm2 5个种植密度处理,比较了不同种植密度对玉米产量、产量构成指标及品质指标影响.结果表明:种植密度对玉米产量及品质有影响.种植密度过高或者过低均会降低玉米产量.综合考虑,认为密度为6.0万株/hm2时,玉米产量及品质最佳,是木里县最适宜的玉米种植密度.
Effects of Planting Density on MaizeYield and Traits
In order to explore the suitable planting density of maize planting in Muli County,the author conducted field experiments in the local area.'Xikang 18'was used as the cultivar,and 45 000 plants/hm2、52 500 plants/hm2、60 000 plants/hm2、67 500 plants/hm2、75 000 plants/hm2five different planting density treatments were set up,and the effects of different planting densities on maize yield,yield composition index and quality index were compared.The results showed that planting density had a significant effect on the yield and quality of maize.Too high or too low planting density will affect the yield of maize,and if the planting density is too high,it will reduce the quality of maize.Considering a number of factors,it was concluded that the yield and quality of maize were the best when the planting density was 60,000 plants/hm2,which was the most suitable planting density in Muli County.
