摘要
大田试验种植早中熟玉米品种和饲用玉米品种,在104天生长期收刈研究不同类型玉米品种的全株生物产量和营养物质产量,试验结果表明,品种间籽实产量差异不显著,不同类型玉米品种的生物产量和营养物质产量有明显差异(p<0.05),种植条件和生长期一致情况下,早中熟玉米品种可以获得与饲用玉米品种相当的可消化有机生物产量。
The effects of different type maize cultivars on yield of vegetative and digestive organ matter m maize were studied. The forage was harvested during milk stage about 104 days. The results indicated that the maize cuhivars had obvious effects on the yield of vegetative and digestive organ matter of corn stalk. During milk stage, the grain yield of corn was not different with the Maize Cultivars.
