Abstract:

To verify the effect of algae active cell biological fertilizer on rice, the authors carried out the application test on rice. The test set blank control, conventional fertilization, algae active cell biological fertilization and two algae active cell biological fertilization with 10% and 20% chemical fertilizer reduction, repeated for three times. The results showed that the application of algae active cell biological fertilizer could promote tillering, increase the percentage of earbearing tiller, the effective spike, the seed setting rate, the number of solid grains and the 1000-grain weight, it also increased the yield of rice and the utilization rate of chemical fertilizer. In particular, reducing chemical fertilizer by 10%-20% could still promote rice growth and increase rice yield. With the application of algae active cell biological fertilizer, the yield of rice could be increased by 1.1%-6.32% and farmers’ income could be increased by -33-1206 yuan/hm².
