我们从1982年的冬季开始,连续4年,先后分别在都江堰灌区内的4个灌溉试验站上进行了土壤湿度对小麦、油菜生理生态影响及其水分生理指标的试验,初步摸索了土壤湿度与水分生理指标的关系,提出了小麦、油菜获得高产的各生育阶段适宜土壤湿度和相应水分生理指标,供灌区制定灌溉制度和进行灌溉预报时参考。 Since the winter of 1982, for four consecutive years, we conducted experiments on the effects of soil moisture on the eco-physiology of wheat and rape and on their hydrophytic indexes at four irrigation stations in Dujiangyan Irrigation District respectively. We tentatively explored the relationship between soil moisture and Water physiological indicators of the proposed wheat, rape obtained high yield of each growth stage of suitable soil moisture and corresponding hydrophytic indicators for the irrigation district to develop irrigation systems and irrigation forecast reference.
