摘要
为探究有机肥在设施番茄生产中的合理施用量,本试验设置不同底施量的商品有机肥、生物有机肥,通过拟合二次曲线得出番茄的最佳施肥量及最佳经济效益。结果表明,商品有机肥的最佳施用量为24.46 t/hm~2,最佳经济效益为211 450.55元/hm~2;生物有机肥的最佳施用量为10.60 t/hm~2,最佳经济效益为209 850.78元/hm~2。
In order to study the reasonable application amount of the organic fertilizer in the facility tomato production,commercial organic fertilizer and bio-organic fertilizer with different base application amount were set in this experiment,the optimum fertilizer amount and the best economic benefit of the tomato were obtained by fitting the quadratic curve.The results showed that the optimum application amount of the commercial organic fertilizer was 24.46 t/hm~2,and the best economic benefit was 211 450.55 yuan/hm~2.The optimum application amount of the bio-organic fertilizer was 10.60 t/hm~2,and the best economic benefit was 209 850.78 yuan/hm~2.
