| Abstract: | The nitrogen content in the soil will increase and the soil fertility will improve after application of the complex biological azotobacter fertilizer which is a biological fertilizer.Adding complex biological azotobacter fertilizer can significantly increase rice yield,combined with conventional fertilization of rice.The results showed that the early rice yields increase by 47.1% and2 083 kg/hm2 on an average,bringing net profits about RMB 3 921 yuan/hm2.On the other hand,the late rice yields increase by 19... |
