随着小麦单位面积产量的逐步提高,国内外在小麦高产栽培中日益重视灌浆期的水肥管理。关于灌浆期间土壤水分条件对小麦物质积累、运输和子粒产量影响的研究,过去已有不少报导,但有些问题仍有待于阐明。Makcимов曾经指出,小麦灌浆期的合理用水十分 With the gradual increase of yield per unit area of ​​wheat, the management of water and fertilizer at the filling stage has been paid more and more attention in high-yield wheat cultivation both at home and abroad. There have been many reports on the effects of soil moisture conditions on wheat accumulation, transport and grain yield during grain filling, but some issues remain to be elucidated. Makcимов once pointed out that the rational use of water in wheat filling period is very good
