在水稻秧苗1叶1心期叶面喷施0、15、30、45,60、75ppm浓度的植物生长延缓剂——特效唑,每个25cm钵里施用6.4毫升药液(等于每亩施100立升)。试验结果表明,特效唑对水稻秧苗有很高的控长、促蘖效应,用30ppm浓度的特效唑处理幼苗即可达到28％的控长率和55.8％的促蘖率。
Spraying 0, 15, 30, 45, 60, and 75 ppm plant growth retarder-oxazole at the leaf-1 leaf-surface of rice seedling, 6.4 ml of liquid (equivalent to 100立 升). The results showed that the control effect of the oxazole on rice seedlings was very high and the tillering effect was promoted. The seedling with the concentration of 30 ppm of the special-azole could reach 28% control rate and 55.8% tillering rate.
