我们于1983年至1984年在大白菜上进行新植物生长调节剂——三十烷醇的试验,并推广应用了二万八千亩,现总结如下。材料和方法本试验采用的三十烷醇系浙江嘉善油脂化工厂生产的水剂,含量为1000ppm,试验的大白菜品种为城阳青。 1983年在大白菜上处理的浓度为0.05、0.1和0.5ppm三种,以喷清水作对照。 1984年在大白菜的幼苗、移栽、莲座、包心等期,以0.5ppm的三十烷醇进行叶面喷雾1～4次,从中摸索最佳使用时期与次数。
We conducted a trial on new plant growth regulator, triacontanol, on Chinese cabbage from 1983 to 1984 and popularized the use of 28,000 acres. We have summarized the following. Materials and Methods The triacontanol used in this experiment was produced by Zhejiang Jiashan Oleochemical Factory with the content of 1000ppm. The tested Chinese cabbage was Chengyangqing. 1983 Chinese cabbage on the concentration of 0.05,0.1 and 0.5ppm three kinds of spray water as a control. In 1984 Chinese cabbage seedlings, transplanting, rosette, heart package phase, with 0.5ppm triacontanol foliar spray 1 to 4 times, from which to explore the best time and frequency of use.
