随着人民生活水平的不断提高,对增产细粮的要求越来越迫切。许多旱作地区因缺乏水源不能发展水田。近几年,我省开展水稻旱地覆膜栽培试验,取得了成功。1983年,全省扩种了9,500亩,平均亩产724.6斤,高产地块亩产超过千斤。证明旱地不仅能种稻,也能创高产。水稻旱地覆膜栽培是在旱田地上覆盖一层微膜薄,具有增加土壤温度、保持土壤湿度、改善土壤结构、提高肥料利用率等作用;并且可使水稻分蘖势增强,叶片增多,活秆成熟。只要选地合理,就可能使水稻在没有水层的情况下获得高产。如在干旱时灌两三次跑马水,经济效益更高。
With the continuous improvement of living standards of the people, the demand for increasing fine grain production is more and more urgent. Many dry areas can not develop paddy fields due to lack of water. In recent years, our province has carried out the experiment of rice cultivation in dry land and achieved success. In 1983, the province expanded its planting area by 9,500 mu and averaged 724.6 kg of mu per mu. Proved dry land can not only grow rice, but also create high yield. The cultivation of rice in the dry land is a kind of thin film coated on the dry land, which has the functions of increasing the soil temperature, keeping the soil moisture, improving the soil structure and improving the utilization rate of fertilizers. It can also increase the tillering potential, the number of leaves, . As long as the land is reasonable, it is possible to make rice yield high without water. Such as irrigation in the drought two or three times horse water, higher economic efficiency.
