密度和施氮水平对渝青1号生物产量及相关性状的影响

Effects of Planting Density and Nitrogen Supply Level on Biomass and Interrelated Characters of Yuqing 1

研究了不同密度和施氮水平对青贮玉米渝青1号生物产量及相关性状的影响,结果表明:密度与施氮量是影响生物产量的关键因素,最适施氮量为225kg/hm2,最适种植密度为8.25万株/hm2。施氮量和种植密度对各相关性状均产生影响。

The effects of planting density and nitrogen supply level on the biomass and interrelated characters of Yuqing 1 were studied. The results indicated that planting density and nitrogen supply level were the key factors influencing the biological yield. The optimal nitrogen supply level was 225kg/hm^2. The best maize planting density was 82500 plants/hm^2. Nitrogen supply and planting density both had influence on the interrelated characters.
