绵阳30号是优良的弱筋小麦品种。为了充分发挥其高产、优质潜力,为大面积推广应用提供参考依据,进行了两年的栽培技术研究。结果表明,氮肥是影响绵阳30号产量和品质的主要因素。绵阳30号的优质高产配套栽培技术模式为:播种期为10月20日至11月1日,密度为195.6万~205.8万株/hm2基本苗,纯氮用量81.9~88.2kg/hm2,P2O5用量61.5~67.5kg/hm2,K2O用量151.5~164.25kg/hm2,氮肥追肥时期以拔节期为宜(氮肥基追比为7∶3)。
Mianyang No. 30 is an excellent weak gluten wheat variety. In order to give full play to its high yield, high quality potential, provide a reference for large-scale popularization and application, conducted two years of cultivation technology research. The results showed that nitrogen fertilizer was the main factor affecting the yield and quality of Mianyang No.30. Mianyang 30 high-yielding and high-yielding cultivation techniques for the mode of sowing from October 20 to November 1, the density of 1.956 million ~ 2.058 million / hm2 basic seedlings, the amount of pure nitrogen 81.9 ~ 88.2kg / hm2, P2O5 dosage 61.5 ~ 67.5kg / hm2, and K2O was 151.5 ~ 164.25kg / hm2. Nitrogen fertilizer topdressing stage was suitable (jointing ratio of nitrogenous fertilizer was 7: 3).
