本文研究京多1号青饲玉米含水量、亩产鲜重和亩产粗蛋白随成熟期变化的规律,并推导出以产值、产量和粗蛋白量的最大值为基础的时间损失系数。结果表明,在试验条件下,京多1号青饲玉米的适宜收获期应为蜡熟初、中期,必要时可延至蜡熟后期;摘取果穗后的京多1号玉米秸用作黄贮的适宜收获期应为完熟初期。
In this paper, the changes of water content, fresh weight per mu and crude protein per mu of Jingdong 1 were studied, and the time loss coefficient based on the maximum value of output, yield and crude protein was deduced. The results showed that the appropriate harvesting period of Jingdoudao No.1 green fodder maize should be the early ripening stage and the middle stage of the mashing process and the later stage of wax ripening if necessary. The appropriate harvest should be early maturity.
