高巧与顶苗新处理水稻种子对秧苗素质的影响及其控虫效果初探
Journal of Henan Agricultural Sciences(2015)
Abstract
采用拌种和浸种2种方法,探讨了高巧+顶苗新药剂组合处理种子后对水稻安全性、秧苗素质的影响,以及对秧田期稻蓟马和灰飞虱的控虫效果.结果表明,每千克稻种用高巧4 mL+顶苗新4 mL拌种、浸种处理对水稻安全性高,且能刺激幼苗生长,有利于培育壮苗;播后30 d拌种、浸种处理对稻蓟马的防效分别为96.41%、90.33%,播后20 d对灰飞虱的防效分别为80.73%、78.21%,可较农户常规防治减少用药2次以上.因此,高巧+顶苗新拌种、浸种技术具有良好的推广应用前景.
