| 摘 要： | 以4个不同类型小麦品种试验为基础,研究了河北低平原区春季不同灌水量对小麦产量的影响趋势。结果表明：小麦产量与春季灌水呈二次曲线关系,即在灌水较少时产量随灌溉增加而提高,当产量提高到最大值之后,随灌溉量增加而出现滞长或降低趋势。合理的灌溉量可以提高小麦产量,但盲目增加灌溉量不仅不能增产还会增加灌溉成本和造成水资源浪费。

| Abstract: | Based on research with 4 different wheat varieties,the influence trend of different spring irrigations on winter wheat yield in Hebei low plain was studied.The results indicated that there was a quadratic curve relationship between wheat yields and spring irrigations.That was to say,when the irrigation was at a low level,the yield improved with the irrigation.However,when the yield reached the peak value,it went down with further irrigation.This result indicated that appropriate spring irrigation increased the wheat yield,but over irrigation would lead to high cost and waste of water resource in Hebei low plain. |
