| 摘 要： | 桑树定植前2-3 a产叶量及产茧量低,单位桑园效益低。桑园合理间作,可以增加土地资源的利用率,提高桑园单位面积的总体经济效益。通过对不同类型桑园间作大豆的试验,结果表明：每hm2桑园产值增加15.4%。说明粮桑间作,增加桑园复种指数,是提高蚕农栽桑养蚕积极性的可行之路。

| Abstract: | The leaf yield,cocoon quantity, and the efficiency were all low in the first 2 to 3 years after planted. Reasonable intercropping could increase the efficiency of the land resource,improve the total economic benefit of the unit area. The results of different type which mulberry orchard intercropping soybean indicated that： the output increasing 15.4 % per hectare. That is to say,the cropping could increase the multiple;crop index,and it could be a feasible approach to improve the activity of the silkgrower. |
