我县稻作区均属于碳酸盐黑钙土和碳酸盐草甸土，土壤粘重、冷凉，ｐＨ值在８左右，影响水稻产量提高，米质不好，效益一直较低。为改变我县水稻生产的面貌，提高米质、节本增收，使水稻生产再上新台阶。我们从１９９４年起开始搞水稻大中棚试验，积累了大量的数据。近年，又与
The rice farming area in our county belongs to the carbonate chernozem and the carbonate meadow soil. The soil is heavy, cold and has a pH value of about 8, which affects the yield of rice and the quality of the rice. The benefits are always low. In order to change the appearance of rice production in our county, improve the quality of rice and increase the production cost, so that rice production can reach a new level. Since 1994, we started to experiment with large and medium-sized rice paddies and accumulated a large amount of data. In recent years, again
