当前,国内外对优质稻米的生产十分关注。稻米的品质除受品种遗传因素影响外,栽培条件的影响也十分重要。因此,实行优质栽培,也是生产优质稻米的重要措施。1.肥料与稻米品质①氮肥施用量过多会使水稻生育期后延,灌浆不充分,死米、青米增多,米粒腹白增加,粮米率、完整米率下降,米饭的粘性和食味变差。②控制水稻生育中期氮肥吸收量可降低稻
Currently, domestic and foreign producers are very concerned about the production of high-quality rice. In addition to the quality of rice genetic factors affected by the variety, the cultivation conditions are also very important. Therefore, implementing quality cultivation is also an important measure to produce good quality rice. 1. Fertilizer and rice quality ① too much nitrogen fertilizer will delay the growth period of rice growth, inadequate filling, dead rice, green rice increase, white belly rice increased, grain yield, complete rice rate decreased, the viscosity and taste of rice Worse. ② control mid-term growth of rice nitrogen absorption can reduce rice
