一、试验的目的意义 我国人口多,耕地少,农业必须走精耕细作的道路。要因地制宜,改革耕作制度,不断提高复种指数,做到用地和养地相结合,充分挖掘土地和空间,水中和水面的增产潜力。 干旱是威胁我省的主要自然灾害之一。长期来,抗御干旱的办法是:除兴修水利外,还利用稻田蓄水过冬,以备来年及时栽秧或抢雨栽插。这是我省水稻生产的一个传统经验,至今尚在发挥一定的作用。自一九七七年春,四川省委从本省农业生产实际出发,提出了“猛攻中稻,大力提高单位面积产量”的方针后,我省中稻生产得到了迅速的恢复和提高,同时
First, the purpose of the experiment China’s population and less cultivated land, agriculture must go intensive road. It is necessary to reform measures to local conditions, reform the farming system, and continuously raise the multiple cropping index so that the combination of land use and raising land can fully tap the potentials for increase in production of land and space, water and water. Drought is one of the major natural disasters that threaten our province. In the long run, the solution to drought has been to use paddy fields to flood the winter in case of water conservancy construction, so as to prepare the plants for planting or planting rainy seasons in the coming year. This is a traditional experience of rice production in our province and is still playing a certain role. Since the Spring of 1977, Sichuan Provincial Party Committee has set forth its policy of “storming mid-sized rice and vigorously raising the output per unit area” from the reality of agricultural production in its own province, and the province’s mid-rice production has been rapidly restored and upgraded. At the same time
