0.0075%28-高芸苔素内酯可溶液剂在水稻上的应用初探

为研究0.0075%28-高芸苔素内酯可溶液剂对水稻生长的调节作用,以水稻“津育粳22”为试材,研究不同浓度药剂对水稻产量和品质的影响。结果表明,在水稻拔节期、抽穗期和灌浆期连续施用3次后,能明显提高水稻的穗长、穗粒数和千粒重,增加水稻产量,0.03125mg/kg浓度下的增产率为10.69%。并且对水稻的生长安全,对品质无明显不良影响。

The study on the application of 0.0075% 28-homobrassinolide SL in rice

To study the effect of 0.0075% 28-homobrassinolide SL on rice growth, rice "Jinyujing-22" was taken as the test material to study the effects of different concentrations on rice yield and quality. The results showed that the features of growth such as panicle length, grain number per panicle and 1000-grain weight of rice increased significantly and the rate of growth was 10.69% at a concentration of 0.03125mg/kg after application at jointing stage, heading stage and filling stage. It has no obvious adverse effect on the growth safety and quality of rice.
