Abstract:Interplanting and interbreeding in mulberry field during slack winter season and sericulture idle period can improve the economic benefit of sericulture production, and increase the income of sericulture farmers. This article summarizes and explores the economic benefits of several typical modes of planting and breeding in mulberry plantation, and raises problems that should be paid attention to improve economic benefits under these modes, so as to provide reference for silkworm farmers to choose suitable interplanting and interbreeding mode according to local conditions to improve benefits.

蠶业生产作为一项“短平快”的产业,是农民增收、提高经济效益和脱贫致富的利好产业。但是单一的蚕业生产随着效益下滑、桑园面积减少、蚕茧价格不稳定、农民种养积极性下降等诸多制约因素影响,与其他经济作物如粮食、蔬菜、水果的种养相比,竞争力明显不足[1]。为了提高农民收益、拓宽致富途径,充分利用蚕业生产中桑园冬息期和蚕作间隔期,农技人员总结出多种桑园套种和套养模式。桑园的套种模式主要有“桑—粮”“桑—蔬菜”“桑—果”[2],桑园的套养主要为“桑—禽”[3-4]模式。为了深入探讨桑园套种、套养模式,本文对典型的几种桑园种植和养殖模式的经济效益进行了总结归纳,以期为农民增收、蚕桑产业的可持续发展提供参考。
1 桑园套种粮油作物模式下的经济效益分析
粮油作物是国计民生不可或缺的农产品。桑园套种粮油作物,可以增加粮食、油料产量,提高单位面积的总体效益。相关研究表明,目前用于套种在桑园的粮油作物有红薯、马铃薯、大麦、玉米、大豆、花生等[5-8]。……
