Abstract: By carrying out the field experiment in Shaxian district, Sanming City, Fujian Province, the effects of different concentrations of organic silicon (BioSilAc) foliar fertilizer and organic biogenic stimulant (OBFs) foliar fertilizer on the growth, yield and nutrient uptake of the post-tobacco rice were studied. On the basis of conventional fertilization, five treatments were set up: treatment 1 (sprayed with 300 L·hm^-2 water, CK), treatment 2 (sprayed with 300 L·hm^-2 BioSilAc solid foliar fertilizer with a concentration of 1.33 g·L^-1), treatment 3 (sprayed with 300 L·hm^-2 BioSilAc solid foliar fertilizer with a concentration of 2.67 g·L^-1), treatment 4 (sprayed with 2 L OBFs liquid foliar fertilizer), and treatment 5 (sprayed with 4 L OBFs liquid foliar fertilizer). The results showed that compared with the treatment 1(CK), the application of BioSilAc solid fertilizer and OBFs liquid fertilizer had no significant effects on the economic character indexes of post-tobacco rice, such as the number of spikes, filled grain number and thousand-grain weight. However, the nitrogen uptake of rice in the treatments 2, 3, 4 and 5 increased by 6.85%, 5.37%, 11.25% and 8.39%, respectively; the phosphorus uptake increased by 8.76%, 18.35%, 20.58% and 10.28%, respectively; and the potassium uptake increased by 5.86%, 8.74%, 15.69% and 5.74%, respectively. In addition, the application of BioSilAc solid fertilizer and OBFs liquid fertilizer could increase the yield of rice in different degrees. Compared with the treatment 1 (CK), the yield of rice in treatment 2 and treatment 3 increased by 9.8% and 9.7%, respectively; and the yield of rice in treatment 4 and treatment 5 increased by 16.2% and 7.5%, respectively. In conclusion, after spraying the foliar fertilizers of BioSilAc and OBFs with different concentrations during the growth period of post-tobacco rice, the uptake of nitrogen, phosphorus and potassium in rice increased, which was beneficial to increase the yield of rice.
