小麦生育期内的降水对产量的影响

Effect of the Rainfall in the Wheat Growth Period on its Yield

1996和 1999年的小麦苗期干旱 ,中后期降水正常 ,全生育期降水为历年平均降水量的 67%和 68.7% ,但小麦产量却比前后 6a的平均产量增产 2 3 .0 7%和 15 .6% ,为小麦节水栽培提供了依据。

In 1996 and 1999, the seedling period of wheat was in drought and the rainfall of middle-late period was normal. In the whole growth period, the rainfall only was respectively 67% and 68.7% of average rainfall in past several years, but the wheat yield was increased 23.07% and 15.6% more that the average yield last six years respectively, so less rainfall in seedling period of wheat won't decrease the wheat yield.
