去年,窟窿台乡水稻旱种600亩,在平均每亩用水量仅为468立方米(我县插秧稻田亩用水量800～1,000立方米)的情况下,水稻单产达913.4斤,其中有16个农户亩产超千斤,最高的达1,168斤。实践证明,只要掌握正确的灌水方法,在土质、地力、水稻品种及施肥水平大致相同的情况下,水稻旱种的产量可以接近插秧的稻田。水稻一生的需水量比大豆、小麦少些,略高于谷子、花生,大致与高粱、玉米相等。水稻苗期耐旱,如果未遇特殊干旱,水稻旱种在4片叶前不必灌水,按一般旱田管理即可。4～6叶期以后,水稻生理生态需水增 Last year, there were 600 mu dry paddy cultivation in Hubultai Township. At an average water consumption of 468 cubic meters per mu (800-1,000 cubic meters mu of rice transplanting paddy field in our county), rice yield reached 913.4 kg, of which 16 Farmer per mu overweight, the highest of 1,168 pounds. Practice has proved that, as long as the right to grasp the method of irrigation, soil, fertility, rice varieties and fertilization levels under the same circumstances, dry cultivation of rice can be close to transplanting rice fields. The water requirement of rice is less than that of soybean and wheat, slightly higher than that of millet or peanut, which is roughly equal to that of sorghum and corn. Drought tolerance in rice seedling stage, if no special drought, dry cultivation of rice in four leaves before irrigation, according to the general dry field management can be. After 4 ~ 6 leaf stage, the physiological and ecological water demand of rice increased
