Abstract
In order to rationally apply organic fertilizer from black soldier fly (BSF) feces, the effects of different amounts (0, 2%, 4%, 6%, 8%) of BSF feces on rice growth were studied through rice pot experiments. The results showed that the dry matter mass and the yield of rice treated with 4% BSF feces were the highest, compared with the control, which were increased by 40.20% and 49.59%, respectively. While the application of 8% BSF feces inhibited the rice plant height, above-ground dry matter mass and rice yield, which were reduced by 9.98%, 22.59% and 22.66%, respectively. The 4% BSF feces promoted the growth of rice and increased yield, which is an reasonable amount of fertilizer.
