稻茬冬小麦的灌溉问题简析

Irrigation for Winter Wheat Grown in Rice Stubble Land

多年来河南人民胜利渠灌区发展稻麦两热制的生产实践和试验研究表明,稻茬冬小麦比一般旱作地冬小麦的田间土壤水分明显偏高,因而必须采用有别于一般旱地冬小麦的灌溉制度。采用本文推荐的灌溉制度,可以显著节约灌水量、减少灌水次数。作者还提出了旱作区发展水稻应注意的几个问题。

Long term practical and testing results, carried out in Renminshengliqu Irrigated Area of Henan province, revealed that the moisture content of the wheatland with rice stubble is obviously much higher than that of common winter wheat land, so that the irrigation procedure for it should be different to that for common winter wheat land. It is pointed out that times of irrigation would be deducted and water use could be saved in accordance with the irrigation procedure suggested in this paper. Problems on development of rice land in this area were raised too.
