随着水利条件的改善,稻麦连作制面积逐年扩大,我县现有水田小麦14万亩。占小麦面积29.2%。提高稻田小麦单产的主要障碍因子是水多,水多的主要原因一是地势低平,地下水位高;二是小麦生产中后期(4—5月)雨水多。据潜江22年资料统计:小麦抽穗至成熟期(4月中旬至5月下旬)每亩小麦需水量103.97立米,折雨量155.9毫米,而实际降水量为209.6毫米,多53.7毫米,多34.4%。 With the improvement of water conservancy conditions, the area of ​​rice-wheat continuous cropping system has been expanded year by year. There are 140,000 mu of paddy field wheat in our county. Accounting for 29.2% of the area of ​​wheat. The main obstacle to improve rice yield is paddy, juicy, the main reason is low ground level, groundwater level is high; the second is the late wheat production (April-May) and more rain. According to Qianjiang 22 years statistics: wheat heading to maturity (mid-April to late May) per acre wheat 103.97 cubic meters of water demand, rainfall 155.9 mm, while the actual rainfall of 209.6 mm, 53.7 mm more, an increase of 34.4% .
