以往试验观察,发现玉米茎秆节间生长与籽粒产量有一定相关性。肥水管理可影响茎秆生长,但常受气候因素所左右,不易达到预期效果。过去报导用乙烯利溶液处理苹果和梨树,可抑制生长发育,处理玉米,可提前抽出雄花。本文报导乙烯利对玉米茎秆生长、株型和产量的影响。 Past experimental observations found that internode growth of corn stalks and grain yield have a certain correlation. Fertilizer and water management can affect the growth of stems, but often affected by climate factors, not easy to achieve the desired results. In the past, it was reported that the treatment of apple and pear with ethephon could inhibit the growth and development of maize, and the male flower could be withdrawn in advance. This article reports the effects of ethephon on the growth, plant type and yield of corn stalks.
