为了探索植物生长调节剂“802”(天门化肥厂提供)在大豆上的施用效果,1988年作者进行了不同生育期叶面喷施和同一生育期(结荚期)喷施不同浓度的试验。试验结果表明: 1.增产效果显著。喷施“802”对大豆的生长发育有良好的促进作用,两个试验均一致表现增产。不同生育期喷施“802”的产量以结荚期效果最佳,亩产达286.0公斤,比对照(喷清水)每亩增产27.7公斤,增产10.7%,达极显著水平;而在分枝期、开花期喷施“802”亦有一定增产效果,但只分别增产3.4％和3.9%。结荚期喷施不同
In order to explore the application effect of plant growth regulator “802” (supplied by Tianmen Fertilizer Factory) on soybean, in 1988, the authors conducted different spraying tests with different concentrations of foliar spray at different growth stages and the same growth stage (podding stage). The test results show that: 1. Increasing yield is remarkable. Spraying “802” on the growth and development of soybean has a good role in promoting the performance of both experiments are consistent with the yield. The yield of “802” sprayed at different growth stages was the best in podding stage, with a yield of 286.0 kg per mu, which increased 27.7 kg / mu and 10.7% per acre compared with the control (spraying water), reaching a significant level. In the flowering stage, spraying “802” also increased production by a certain amount, but only increased by 3.4% and 3.9% respectively. Pods spraying different
