江优126施用吨田宝适宜时期与喷施浓度研究

Study of Appropriate Applying Time and Concentration of Foliar Fertilizer Duntianbao on Jiangyou 126

为探索吨田宝在水稻新品种江优126生长过程中的最佳喷施时期与喷施浓度,开展了试验研究。试验结果表明,施用吨田宝最佳适宜时期为分蘖盛期与齐穗期,在拔节期喷施吨田宝的效果欠佳.喷施浓度在分蘖盛期、齐穗期以喷施双倍浓度(60ml兑水15kg/667m2)为好,建议推广应用。

To explore the appropriate applying time and concentration of foliar fertilizer Duntianbao on rice variety Jiangyou 126,it was carried out in field test. The results showed that the best time is in tellering stage and full heading stage,it shows lower yield at joiting stage. The concentration of 60 ml/667 m2 at tellering stage and full heading stage were better than joiting stage,so it was proposed on production.
