以瑞华麦520为供试材料,采用9个不同密度处理,研究种植密度对瑞华麦520产量及其构成因素的影响,以期获得瑞华麦520的最佳种植密度。结果表明:随着种植密度的增加,瑞华麦520的有效穗数呈上升趋势;穗粒数和千粒重呈下降趋势。且瑞华麦520的三值产价随着密度的增加,穗值呈现负相关的态势,粒值和重值均增加达到一定值后呈下降趋势。该试验得出瑞华麦520的最佳种植密度是基本苗为360万株/hm2,产量达8 686.9kg/hm2。
The effects of planting densities on the yield and its components of Ruibao 520 were studied with 9 different densities in order to obtain the optimum planting densities of Ruibao 520. The results showed that with the increase of planting density, the effective panicle number of Ruiwaer 520 showed an upward trend; the number of grains per panicle and the 1000-grain weight tended to decrease. With the increase of density, the value of three-valued production of Ruiwaitai 520 showed a negative correlation, and both the value of grain and weight increased at a certain value and then decreased. The results showed that the optimum planting density of Ruihuamai 520 was 3.6 million plants / hm2 and the yield was 8 686.9 kg / hm2.
