EF植物生长促进剂(简称EF)是一种高效、广谱、无毒、无污染的新型植物生长调节物质。近年来国内陆续报道过EF对油菜、棉花、蔬菜、葡萄、花生、西瓜,以及一些花木、果树等的生长发育有明显的促进效果,不仅能提高产量,还可改善品质,是有较好的经济效益。我们于1987年在烤烟上进行了 EF 应用试验,试验在江西农业大学农学系教学试验站进行,品种为 G—140,供试 EF 药剂由广东雷州林业局林产化工厂提供(有效成分约13%),设400、600和800ppm 三种浓度处理,以喷清水为对照。重复四次,小区面积0.03亩,随机区组排列。第一次喷药在团棵期,隔10天
EF Plant Growth Enhancer (EF) is a new plant growth regulator with high efficiency, broad spectrum, non-toxic and pollution-free. In recent years, it has been reported in China that EF has a significant promotion effect on the growth and development of rapeseed, cotton, vegetables, grapes, peanuts, watermelon, as well as some flowers and trees and fruit trees, which not only improves the yield but also improves the quality, Economic benefits. We carried out the application of flue-cured tobacco in 1987 on the EF experiment, Jiangxi Agricultural University Agronomy Teaching Experimental Station, the varieties of G-140, for the EF test agent from Leizhou Forestry Bureau of Guangdong Forest Chemical Plant (the active ingredient of about 13% ), Set 400,600 and 800ppm three concentrations of treatment, spray water as a control. Repeat four times, the plot area of 0.03 acres, random block arrangement. The first spray in the corps, every 10 days
