为掌握不同类型饲用玉米生长发育规律、产量和品质之间的差异。试验以4个青贮玉米品种:吉饲8、金刚12、吉饲9和金刚50为材料,设置5万、6万、7万和8万株hm24个密度进行叶面积、干物质积累和品质指标等性状研究。结果表明:品种间受密度影响,生长发育存在差异。品种内产量和品质性状也有所不同,同一品种在不同密度条件下的产量和品质也存在差异。在8万株hm2密度下,吉饲9品质和产量最高,其表现出较好的耐密性和丰产性。
To grasp the different types of foraging corn growth and development law, the difference between yield and quality. Four silage maize varieties, Kyrgyzstan 8, Vajra 12, Kyrgyzstan 9 and Vajra-5, were used as materials to set up the leaf area, dry matter accumulation and quality of 50000, 60,000, 70,000 and 80,000 hm24 densities Indicators and other traits. The results showed that there was difference between the varieties affected by the density and the growth and development. Within the variety of yield and quality traits are also different, the same variety in different densities of yield and quality are also different. At the density of 80000 hm2, Kyrgyzstan 9 had the highest quality and yield, which showed better tolerance and high yield.
