不同生育期灌水量及培肥措施对玉米产量和水分利用率的影响

Effect of Amount of Irrigation and Fertilizing Measures at Different Growing Stage on Yield and Water Use Efficiency of Maize

白城市属温带大陆性气候,主要特征春季少雨多风,干旱发生频次和程度异常突出,对农业生产已构成极大危害。本文通过对玉米的需水规律、增施有机肥等措施的研究,阐述了玉米在各个不同生育期的灌水量及培肥地力等蓄水保墒高产栽培技术措施对玉米产量和水分利用率的影响。

Baicheng City has a continental climate,with main features of dry windy and less rain spring.Frequency and extent of drought is abnormal prominent,so it pose a great danger on agricultural production.By the study of regularity of water requirement of maize and applying organic fertilizer and other measures,effect of cultivation measures,such as irrigation and applying fertilizer at different growing stages and water preserving measures,on maize yield and water use efficiency was described in the paper.
