超高茬麦套稻秸秆全量还田栽培技术,是一项水稻新的轻简高产高效栽培技术,已在成都市的崇州推广应用了2年,面积达30 hm2,节本增效十分明显。通过超高茬麦套稻秸秆全量还田栽培技术N肥效应试验,探索了应用该高产技术的最佳N肥施肥量和最佳经济施肥量,成都平原土壤肥力水平总体较高,在施肥上应比一般的大田管理适当增施,施纯N肥应控制在100~125 kg/hm2。
Ultra-high stubble wheat straw rice crop return to full cultivation technology, is a new rice light simple and high yield and efficient cultivation techniques, has been applied to the city of Chongzhou in Chengdu for 2 years, an area of 30 hm2, section cost efficiency is very obvious. The results showed that the soil fertility level of Chengdu Plain was generally high, and the best fertilization amount and the best economic fertilizer amount were obtained by applying the N fertilizer effect experiment. Should be appropriate than the general management of field operations, Shi Chun N fertilizer should be controlled at 100 ~ 125 kg / hm2.
