Abstract:

To investigate the effects of castor bean microbial enzyme biological fertilizer on the growth, fruit yield, and quality of tomato plants, a pot experiment was conducted using cherry tomato varieties as experimental materials. A total of five treatments including no fertilization (CK), chemical fertilizer (HF, 4 g/plant) and three different application gradients [20 g/plant(BF1), 40 g/plant(BF2), 80 g/plant(BF3)] of castor bean microbial enzyme biological fertilizer were set up. The results showed that compared with CK, the plant height of tomato plants treated with BF3 during the fruiting and harvesting periods increased by 16.82%-20.23%. During the fruiting period, the stem diameter of BF2 treatment increased by 34.04%, and during the harvesting period, the stem diameter of BF1 treatment increased by 41.30%. Fruit weight and number of fruits per plant of BF1 treatment were the best during the harvesting period, and the average yield per plant increased by 496.98%. The content of vitamin C, soluble sugar, soluble protein, and soluble solids in tomatoes treated with BF3 increased by 28.57%, 63.49%, 77.43% and 16.43%, respectively. The dry matter mass of roots, stems and leaves showed a trend of first increasing and then decreasing with the increase of application rate of castor bean microbial enzyme biological fertilizer. 20 g/plant of castor bean microbial enzyme biological fertilizer has a significant promoting effect on the growth and yield of tomato plants, while 80 g/plant of castor bean microbial enzyme biological fertilizer has the best effect on the fruit quality of tomato plants.
