合理追肥是调节小麦生长发育的重要手段,也是夺取小麦丰产的关键。这可使一定量的化肥发挥较大的增产效果,特别是在创高产的情况下,通过肥水的合理运筹,达到穗多、穗大,不倒、子粒饱满,成本又低的要求,这更是小麦高产栽培中需要解决的关键问题。如何把追肥的运用与小麦生长发育的内在需要结合起来,从而提高追肥的合理性,减少其盲目性,这既是提高冬麦增产效果的关键,也是扭转低产亏损局面的重要一环。
Rational top dressing is an important measure to regulate the growth and development of wheat and it is also the key to seize the high yield of wheat. This will enable a certain amount of fertilizer to exert greater stimulation effect, especially in the case of a high yield, through the rational operation of fertilizer and water, to spike more, spike, not fall, full grain, low cost and more Wheat is the key issue to be solved in high-yielding cultivation. How to combine the application of topdressing with the inherent needs of wheat growth and development so as to improve the rationality of topdressing and reduce its blindness is not only the key to increasing winter wheat yield but also an important part to reverse the situation of low yield loss.
