| Abstract: | Objective] The research aimed to study the effects of harvesting time on the main chemical components in the stalks of corn varieties Zhongdan No.9409 and Zhongyuandan No.32.Method] Taking corn varieties Zhongdan No.9409 and Zhongyuandan No.32 as test materials,the effects of harvesting time on their main chemical components were studied.Result] The stalks of Zhongdan No.9409 harvested in 1/4 milk line stage had the highest nutritive value,and the nutritive value in other harvesting stages had no significant difference.The stalks of Zhongyuandan No.32 harvested in 3/4 milk line stage had the highest nutritive value,and its nutritive value in 1/4 milk line stage was the second,and that in 4/4 milk line stage was the worst.Conclusion] The best harvesting time of Zhongdan No.9409 was winter-killing time,which was favorable for the accumulation of nutriments in corn grains. |
