为探讨乙烯利对增加小麦每穗粒数、提高千粒重和提前成熟的作用,我们在前两年初步试验的基础上,于1980-1981年在农学院(许昌)进行试验,现将试验简况与结果分析总结如下:材料与方法(一)材料:供试品种为郑引1号、郑州761、百泉41、豫麦1号(本院新育品种).(二)试验设计:为探讨乙烯利在小麦孕穗期的处理效应,设计CK(清水)、40、80、120、200、400、600、800、2000、4000PPM 10个处理
In order to explore the effect of ethephon on increasing the number of grains per spike and increasing the 1000-grain weight and premature maturity, we conducted the experiment at Agricultural College (Xuchang) from 1980 to 1981 based on the preliminary tests of the previous two years. The results are summarized as follows: Materials and Methods (I) Materials: The varieties tested were Zheng Yin 1, Zhengzhou 761, Baiquan 41 and Yumai 1 (newly bred in this hospital) Lee treatment effect at the booting stage of wheat, design CK (fresh water), 40,80,120,200,400,600,800,2000,4000 PPM 10 treatments
