为充分发挥弱筋小麦绵阳30号的高产、优质潜力,为大面积推广应用提供参考,特进行了两年的栽培技术研究。研究结果表明:①影响绵阳30号品质的主要因素为:施氮量>施钾量>密度,施磷量与追肥时期对品质影响较小。②绵阳30号的优质高效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195.6～205.8万/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)。
In order to give full play to the high yield and high quality potential of weak-gluten wheat Mianyang No.30, provide a reference for popularization and application of large-scale wheat, especially for two years of cultivation technology research. The results showed that: (1) The main factors affecting the quality of Mianyang 30 were as follows: nitrogen application rate> potassium application rate> density, phosphorus application rate and dressing time had little effect on quality. ② Mianyang 30 high-quality and efficient cultivation techniques for the mode of cultivation: sowing for the October 20 to November 1, the density of 195.6 ~ 205.8 万 / hm2 basic seedlings, the amount of pure nitrogen 81.9 ~ 88.2kg / hm2, P2O5 dosage 61.5 ~ 67.5kg / hm2, and the dosage of K2O was 151.5 ~ 164.25kg / hm2. The nitrogenous fertilizer topdressing stage was suitable at the jointing stage (N: N ratio was 7: 3).
