()
Abstract:
In order to study the reasonable application of the organic fertilizer in the production of the facility tomato, the optimum fertilizer amount and the best economic benefit of the tomato were obtained by fitting the second curve with the commercial organic fertilizer and the bio-organic fertilizer. The results show that the optimum application amount of the organic fertilizer is 1.63t/667m2, the best economic benefit is 14098 yuan/ 667m2, the optimal application amount of the bio-organic fertilizer is 0.71 t/667m2, and the best economic benefit is 13989. 52 yuan/ 667m2.
Key words:  Tomato  Commercial organic fertilizer  Biological organic fertilizer  Optimum fertilization  Optimum economic benefit
