研究了播期、密度、施氮量及氮肥运筹比例和氮磷钾配比对弱筋小麦扬麦15优质高产群体的调控效应,结果表明:弱筋小麦扬麦15实现产量与品质协调发展的适宜播期在10月22日~11月5日左右,最适密度在210万~245万/hm2,施氮量180~240 kg/hm2,氮肥运筹(基肥∶壮蘖肥∶拔节肥)比例为7∶1∶2,氮磷钾配比为1∶0.6∶0.6。在本试验条件下,10月29日播种,密度240万/hm2,施氮量180 kg/hm2,氮肥运筹(基肥∶壮蘖肥∶拔节肥)比例为7∶1∶2,氮磷钾配比为1∶0.6∶0.6,产量>6 000 kg/hm2,子粒蛋白质含量<11.5%,湿面筋含量<22%,符合弱筋小麦国标(GB/T17893-1999)要求。
The effects of sowing date, planting density, nitrogen application rate, proportion of N fertilizer and N, P and K fertilization on the regulation of Yangmai 15 with high gluten wheat content were studied. The results showed that the weak gluten wheat Yangmai 15 could achieve the coordinated development of yield and quality The suitable sowing date is from October 22 to November 5, the optimum density is from 2.1 million to 2.45 million / hm2, and the nitrogen application rate is from 180 to 240 kg / hm2. The proportion of nitrogenous fertilizer application (basal fertilizer: strong tillering fertilizer: jointing fertilizer) 7: 1: 2, NPK ratio of 1: 0.6: 0.6. Under the experimental conditions, the planted on October 29, density 2.4 million / hm2, nitrogen application rate of 180 kg / hm2, nitrogen fertilizer operation (basal: stout tillering fertilizer: jointing fertilizer) ratio of 7: 1: Ratio of 1: 0.6: 0.6, yield> 6 000 kg / hm2, grain protein content <11.5%, wet gluten content <22%, in line with the national standard of weak gluten wheat (GB / T17893-1999) requirements.
