广西忻城县桑园低产原因分析及综合治理措施

Cause Analysis and Comprehensive Treatment Measures of Mulberry Garden Low-yield in Xincheng County,Guangxi

针对忻城县蚕区桑园低产的问题开展专题调研,分析造成低产的主要原因可概括为2个方面:生产条件方面,分布在旱坡地、沙滩地和石漠化区域的桑园,其地块零碎且地块间的水平高度差较大,桑园的水土保持差,土壤贫瘠肥力不足;生产管理方面,桑品种未进行大规模更新换代,桑园无基础灌溉条件设施,仅依靠雨水灌溉,加上留守在乡村的种桑养蚕人员年龄普遍偏大而疏于对桑园的管理,日积月累导致桑园土壤板结、病虫害发生严重等。针对以上造成桑园低产的原因,提出完善基础设施、推行适度规模经营、建设标准化桑园、强化桑园水肥管理、加强桑树病虫害防治、加大政策与资金扶持等综合治理措施,期望从桑园高产着手,助力忻城县蚕桑产业提质增效。

The paper carried out a special investigation on the problem of low-yield in mulberry garden,in Xincheng County.The analysis of the main reasons for low-yield could be summarize into two aspects.In terms of production conditions,the plots of the mulberry orchard distributed in the arid slope land,sandy land and rocky desertification area were fragmentary and the horizontal height difference between plots was large.The soil and water conservation of the mulberry orchard was poor and the soil fertility was insufficient.In terms of production and management,the mulberry varieties have not been upgraded on a large scale,the mulberry garden has no basic irrigation facilities,and only relies on rainwater irrigation.In addition,the remaining mulberry growers are generally too old to manage the mulberry garden,which leads to soil compaction,serious diseases and insect pests.In view of the above reasons for the low yield of mulberry garden,comprehensive treatment measures are proposed,such as improving infrastructure,implementing moderate scale operation,building standardized mulberry garden,strengthening the management of water and fertilizer in mulberry garden,strengthening the prevention and control of mulberry diseases and pests,and increasing policies and financial support.We hope to start from improving the output of mulberry garden,and help Xincheng sericulture industry to improve the quality and efficiency.
