| Abstract: | The results of six years researches show that the output and productive value of crops in the process of agricultural production are all promoted, especially the quality of agricultural products is improved and the pollution of nitrate is reduced, by applying balanced fertilizers of N, P and K fertilizer, adding useness of the good quality microfertilizers, com-binating the microfertilizer, organic fertilizer and inorganic fertilizer, and reducing the amount of chemical fertilizer. Adding useness of microfertilizer and organic fertilizer can reduce the using amount of chemical fertilizers by 10% and 50% respectively, in addition, the nitrate in the edible parts of vegetables can be reduced by 17.04% -24. 86% . |
