三十烷醇是一种新型的植物生长调节剂,能提高作物光合作用效率,改善植物细胞对水份、养份的吸收,促进细胞数目、蛋白质和干重的增加。据报道,水稻等作物喷施三十烷醇后,有较明显的增产效果。1982年我县组织了三十烷醇喷施水稻增产效果的试验,结果表明与外地的结果完全一致,1983年已列入全县推广项目。试验在全县7个点上进行。喷施时间在水稻开花初期至灌浆初期,喷施次数为1— Triacontanol is a new plant growth regulator that increases the photosynthetic efficiency of crops, improves plant cell absorption of water and nutrients, and increases cell numbers, protein, and dry weight. It has been reported that rice and other crops sprayed triacontanol, there is a more obvious yield increase. In 1982, the county organized a test of increasing the yield of rice with triacontanol. The results showed that the result was consistent with the results in other places. In 1983, it was included in the promotion project of the county. Test in the county 7 points. Spraying time in early rice flowering to early filling, spraying times for the 1-
