摘要: 免耕机条播是沿湖涝洼湿地生态区稻茬麦的主要播种方式之一,为探讨其科学栽培技术,分别对免耕机条播稻茬麦的冬前苗,叶面积系数、后期根系活力、播期、播量和多效唑化控进行了研究。结果表明,与稻田套播相比,机条播小麦的基本苗降低了150万/hm2,冬前主茎叶片增加了0.8个,单株茎蘖增加0.9个,单株次生根增加1.4条,茎粗增加1.1mm,地上部鲜重增加0.17g,叶面积系数动态为:冬前0.8,起身1.6,拔节期4.0,挑旗期6.2,灌浆期4.0,后期根系活力分别增加1.21、1.02、0.47,使用多效唑第1、2、

Abstract: Drilling with zero-tilling machine was the main mode of wheat after rice in wetland where near to lakes. In order to get the right technology, we studied the effects of drilling with zero-tilling machine on seedlings before winter, leaf area index, and roo
