【摘要】 在有限灌水资源的麦田,进行了不同灌水数量和不同施肥量的多年试验,结果表明,施N量与产量、穗数、穗粒数关系密切,而与千粒重的关系不密切;灌水数量的表现则不同,与穗数、穗粒数关系不密切,而通过千粒重的显著变化影响产量;肥水互作效应不显著,生产上在有限水资源情况下,可依靠多施肥发挥以肥补水的作用。更多还原

【Abstract】 The experiment with various quantities of irrigation water and fertilizer has been carried out in wheat field with limited water for several years. The result shows that the quantity of nitrogenous fertilizer has close relation with output, the amount of ear and the amount of grain of each ear, but is not closely related to the weight of every thousand grains. However, the quantity of irrigation water is not closely related to the amount of ear and the amount of grain of each ear, but affect output through the great influence on the weight of every thousand grains. The coupling effect of water and fertilizer is not distinct and more fertilizer can be used to compensate for the shortage of water under limited water resources.更多还原
