提灌提排又叫扬灌扬排,采用水泵,从低洼处向一定高程上抽水,进行灌溉和排水,常建成排灌站比单一的灌溉站或排水站经济效益高。在低洼盐碱地区旱时灌水又能压盐,排水时又能排盐,降低地下水位,从而有效地调节土壤水分和减轻土壤中的盐分,提高了作物的产量。因此,扬灌扬排是改造盐碱,排除旱涝碱的一项重要措施。灌水,提高了作物产量:农谚说:“有收无收在于水,多收少收存于肥”,进行灌水能满足 Irrigation and lifting also called Yangrong Yang row, the use of pumps, pumping water from a low elevation to a certain elevation, irrigation and drainage, irrigation stations often built than a single irrigation station or drainage station economic benefits. In the low-salt saline-alkali region, irrigation can press the salt water, drain the salt while drainage, reduce the groundwater level, effectively adjust the soil moisture and reduce the salt in the soil, and increase the crop yield. Therefore, Yang-Yang Yang Pai is the transformation of saline-alkali, an important measure to eliminate droughts and alkali. Irrigation, increased crop yield: Farming proverb said: “There is income confiscated in the water, more income less received in the fertilizer,” irrigation can meet
