多效唑是一种新型的植物生长调节剂,能够有效地控制花生中后期的徒长,协调营养生长和生殖生长的关系,提高产量.目前关于合理的施用浓度研究尚少。1990年以来,我们引用江苏建湖农药厂生产的15％多效唑可湿性粉剂在兰家、崖头,黄山三乡镇5个点连续进行适宜浓度试验研究,现将试验结果简报如下。 Paclobutrazol is a new plant growth regulator, which can effectively control the peculiar growth in late peanut, coordinate the relationship between vegetative growth and reproductive growth, and increase the yield.At present, there is little research on the reasonable application concentration. Since 1990, we quoted 15% PP33A WP produced by Jianhu Pesticide Factory in Jiangsu Province for five consecutive consecutive experiments at Lanjia, Yatou and Huangshan townships. The results of this trial are summarized as follows.
