| 摘 要： | 本文的八个试验结果表明:品种和茬口、肥力、播期、播量、耕作深度等栽培措施,对小麦籽粒产量均有十分重要影响;但对其品质的作用,除品种外,主要是肥力,其它措施影响不大。肥力因素中,对改进品质起主要作用的是氮素的充足供应。磷对改进品质几乎无效。就改进品质而言,氮肥的施用方式和时间是以开花期根外喷氮的肥料效益最高。在地力能生产250公斤/亩小麦的地块上,喷洒3%的尿素液100公斤左右,比不喷的不仅增产14.84%(39公斤/亩),而且蛋白质提高2.3%,湿面筋提高7.7%,赖氨酸增加0.13%。故开花期喷氮素是改善小麦营养品质和加工品质经济有效的措施。

| Abstract: | Field experiment results showed that cultivars, fertility of soil, dateof sowing,rate of seeding and tilling depth had significant effects on thegrain yield of wheat.The major factor that affected wheat grain qualitywas soil fertility, besides genotype, the other cultural measures had lesseffects on the qualities.It is the sufficient nitrogen application, among the fertility factors,that takes a important role in, while phosphorus has little effects on im-proving the grain quality of wheat. And as for the amelioration of grainquality, the foliage splay at anthesis is the most effieient way of apply-ing nitrogen fertilizer. |
