大棚鲜食蚕豆间作蔬菜不同方式的经济效益研究

摘要

研究了大棚鲜食蚕豆在100 cm等行距、（130 cm＋70 cm）宽窄行和（160 cm＋40 cm）宽窄行3种行距规格下分别间作莴苣、黑塌菜和豌豆的收益、成本和经济效益。结果表明：蚕豆间作黑塌菜表现为收益高、成本低、经济效益显著；蚕豆在较宽行距下间作莴苣具有良好的增效作用；蚕豆间作豌豆表现为成本高、收益低、经济效益不理想。%This article studied the income , cost and economic benefit of fresh -eating broad bean intercropped by lettuce , black savoy and pea respectively in greenhouse , and the row spacing of broad bean was designed as follows:100 cm, 130 cm+70 cm, and 160 cm+40 cm.The results showed that the broad bean intercropped by black savoy had the highest income , the lowest cost and the largest economic benefit;the broad bean intercropped by lettuce in wider row spacing had obvious synergism ;the broad bean intercropped by pea had the highest cost , the lowest income and the lowest economic benefit .
