徐州地区常年小麦生育期间温光资源丰富,但降水量不足,特别旱改水以来水分供求矛盾更加突出,已成为限制小麦产量提高的主要因子。针对此问题,我们于1981～1986年对不同条件下的小麦需水量、需水规律进行了系统研究,并结合气象资料探讨其经济合理的灌溉模式。 研究方法 During the period of wheat growth in Xuzhou, there are abundant light and abundant resources during the growth of wheat in Xuzhou, but the precipitation is not sufficient. The contradiction between supply and demand of water has become more prominent since drought and water change, which has become the main factor limiting the yield increase of wheat. In response to this problem, we systematically studied the wheat water requirement and water requirement under different conditions from 1981 to 1986, and discussed the economical and reasonable irrigation mode based on the meteorological data.
