乙烯利(有效成份2-氯乙基瞵酸是一种能释放乙烯的植物生长调节剂。近年,国内外将其应用于果蔬的催熟等方面已取得了显著的成效。相比之下,乙烯利应用于粮食生产特别是玉米上的研究甚少。我们1986～1987年试验表明,当玉米亩株数增加1500～2000株,于叶龄指数65～75喷洒600～1000ppm乙烯利后,均可增产1～2成。在此基础上,我们又作了进一步的研究和示范,于前文(《耕作与栽培》1990年第4期)报道了乙烯利对玉米根系的影响,本文探讨其对玉米株型和产量的影响,以及实际应用的适宜技术。
Ethephon (The active ingredient 2-chloroethyl gallate is a plant growth regulator that can release ethylene.) In recent years, remarkable achievements have been made at home and abroad in applying it to the ripening of fruits and vegetables, etc. In contrast, The application of ethephon to grain production, especially to corn, is very poor.Our experiments from 1986 to 1987 showed that when the number of acres per acre was increased by 1,500-2,000, the leaf age index of 65 ~ 75 was sprayed with 600 ~ 1000ppm of ethephon, Increase production 1 to 2 percent.On this basis, we have made further research and demonstration, in the previous (“farming and cultivation” 1990 the fourth period) report ethephon on the impact of corn root system, this paper discusses the corn Plant type and yield, as well as the practical application of appropriate technology.
