优质饼干小麦———宁麦 9号在沿海沙性粉土地区种植 ,产量表现十分突出 ,肥料报酬率也较高。栽培上以亩施 12 .5～ 17.5kg纯氮 ,配以 15～ 2 0万基本苗的处理增产效果最佳 ,籽粒优质性状也能得到较充分的表达 ,从而较好地协调了高产与优质的矛盾。本文还探讨了不同处理下 ,宁麦 9号产量变化的原因及其因素间的相互关系。 High-quality biscuit wheat --- Ningmai 9 is planted in the coastal sandy silt area, the yield is outstanding, and the return rate of the fertilizer is also higher. Cultivation of 12.5-15.5 kg of pure nitrogen per acre with 15 to 20 million basic seedlings of the treatment of the best yield, grain quality traits can be more fully expressed, so as to better coordinate the high yield and quality Contradictions. The paper also discussed the reasons for the change of yield of Ningmai 9 under different treatments and their interrelationship.
