叶面喷施S3307增产绿豆的最佳时期和浓度筛选

Optimum Time and Concentration Screening of Increasing S Yield Mung Bean by Foliar Spraying

烯效唑(S3307)可以控制植物的营养生长,促进植物的生殖生长,增加作物产量。本试验通过分别在苗期、分枝期、现蕾期、盛花期喷施不同浓度的S3307并测量产量,以筛选出促进绿豆增产的最佳时期和浓度。试验在2016年喷施清水(CK)和60、90、120 mg/L浓度的S3307,2017年喷施清水(CK)和90、120、150 mg/L浓度S3307。两年的试验结果显示,在各时期绿豆叶面喷施各浓度S3307均提高了绿豆的产量。2016年试验结果表明苗期在绿豆叶片喷施浓度为120 mg/L的S3307增产效果更明显;经2017年试验验证,与2016年结果一致。因此,叶面喷施S3307的方法适合用于提高绿豆产量,最佳的喷施时期是绿豆苗期,最佳的S3307喷施浓度为120 mg/L。

S3307 can be used to control the vegetative growth of plants, promote the reproductive growth of plants and increase crop yield. In this experiment, different concentrations of S3307 were sprayed at seedling stage, branching stage, squaring stage and flowering period, and the yield was measured to screen out the best time and concentration to promote mung bean yield. In this experiment, water was as CK, S3307 at 60 mg/L, 90 mg/L and 120 mg/L were sprayed in 2016;S3307 at 90 mg/L 120 mg/L and 150 mg/L were sprayed in 2017. The experimental results of two years showed that the yield of mung bean was increased by spraying each concentration of S3307 on the leaf surface of mung bean in each period. The test results in 2016 showed that S3307 with a concentration of 120 mg/L sprayed on mung bean leaves at seedling stage had a more obvious stimulation effect. The 2017 trial confirmed the same results as in 2016. Therefore, the method of spraying S3307 on the leaf is suitable for increasing the yield of mung bean. The best spraying period was the seedling stage of mung bean, and the best spraying concentration of S3307 was 120 mg/L.
