NOVELTY - Biopesticidal fertilizer comprises coltsfoot, JT bacterial strain complex, rapeseed meal, silicon fertilizer, and farmyard manure. Preparation method of the farmyard manure, involves mixing dried and crushed cow dung, chicken manure and pig manure with crushed plant stalks, fermenting mixture, crushing dried decomposed fertilizer and sieving crushed product. The farmyard manure is uniformly mixed with crushed coltsfoot, rapeseed meal and silicon fertilizer, then inoculated with JT bacterial strain complex, and finally incubated to obtain biopesticidal fertilizer.    USE - As biopesticidal fertilizer.    ADVANTAGE - The biopesticidal fertilizer enables to increase soil activity and prevent hardening of soil due to presence of farmyard manure, reduce usage amount of chemical fertilizers and inhibit other harmful bacteria and breeding of pests in soil due to presence of beneficial bacterial strains, improve pest resistance of plants due to presence of coltsfoot, and provide enhanced fertilization effect due to presence of silicon fertilizer.    DETAILED DESCRIPTION - Biopesticidal fertilizer comprises 5-8 pts. wt. coltsfoot, 0.5-3 pts. wt. JT bacterial strain complex, 65-80 pts. wt. farmyard manure, 10-15 pts. wt. rapeseed meal, and 3-7 pts. wt. silicon fertilizer. Per 100 pts. wt. of the farmyard manure comprises 15-20 pts. wt. cow dung, 35-43 pts. wt. chicken manure, 12-15 pts. wt. pig manure, and 25-40 pts. wt. plant stalks. Preparation method of the farmyard manure, involves (a) drying the cow dung, chicken manure, and pig manure until water content reaches 55-60%, and crushing dried products using crusher into crushed product having particle diameter of not greater than 0.8 cm, (b) crushing plant stalks such that length of the stalks is not greater than 0.5 cm, (c) mixing crushed products obtained in the above-mentioned steps (a) and (b) uniformly, and fermenting obtained mixture for 30-40 days to obtain decomposed fertilizer, and (d) drying the decomposed fertilizer until water content reaches 20-25%, crushing dried product, and sieving obtained crushed product through 120 mesh size sieve. The farmyard manure is uniformly mixed with crushed coltsfoot, rapeseed meal and silicon fertilizer, obtained mixture is inoculated with JT bacterial strain complex, and then finally incubated at 15-20 degrees C or less for 2-3 days to obtain the biopesticidal fertilizer.
