我省水稻低而不稳的望天田约有600—800万亩;小麦低产的旱地约有400—450万亩。限制我省商品粮生产发展的关键是水。云南是一个年降水(特别是大春雨季)较多的省份,不是水少,而是未用好。长期以来把解决农业用水仅是放在兴修水利上,对于通过栽培措施用好雨季降水和保持旱季土壤水分极不重视,有关部门也很少研究。我们
Our province rice low and unstable Wang Tian Tian about 600-800 acres; wheat low yield dry land about 400-450 acres. The key to limiting the development of grain production in our province is water. Yunnan is a province with more annual precipitation (especially the spring rainy season). It is not less water but less used. For a long time to solve agricultural water use is only on the water conservancy project, for the cultivation measures to make good use of rainfall in the rainy season and to maintain the dry soil moisture very seriously, the relevant departments seldom studied. we
