Effect of Slow Release Fertilizers on Yield and Population Structure of Hybrid Rice
To improve the fertilizer utilization rate and increase the rice yield,the experiment investigated the effect of different types of slow release fertilizers on hybrid rice'Yongyou 12'.The results showed that'Hanfeng'slow release fertilizer had a significant effect on yield increase,which was 2.7％-3.5％higher than that of the formula fertilizer.'Liuguowang'slow release fertilizer and'Fengzhu'slow release fertilizer had no significant yield increase effect.The spike rate and the number of grains per spike under'Hanfeng'slow release fertilizer were higher than that of others,which compensated the lower effective spike number.The leaf area index and dry matter under'Hanfeng'slow release fertilizer were the highest in growth.Based on the performance of yield and population characteristics,'Hanfeng'slow release fertilizer was better than that of'Liuguowang'and'Fengzhu'.It could provide a basis for seed-specific fertilization of'Yongyou 12'.
