枸杞是茄科 Lycium 属灌木。据记载此属植物在我国有7种之多,而传统上作为药用的只有宁夏枸杞(Lycium barbarumL.)、中国枸杞(L.chinensis Mill.)两种。这两种枸杞以野生状态广布于我国北方,其中宁夏枸杞的品质和功效向为历史医家所称道,有“果味似甘露,一酌可延年”之功。近六百年来已发展为优良栽培种。宁夏的银川市和中宁县是集中产地。近年全国许多省区从宁夏大量引种,东北、西北、华北及江浙一带均有大面积栽培和试种,但这种植物的害虫种类多而为害重。常因害虫猖獗而形成大面积减产和品质低劣。在野生条件下,虫群密度更高,常10余种混合发生,自成一个寄主植物所特有的昆虫区系。现分析讨论于下。 Wolfberry Lycium genus shrubs. It is recorded that there are 7 species of this genus in our country. Traditionally, only Lycium barbarum L. and L. chinensis Mill. Have been used as medicinal herbs. These two kinds of wolfberry to the wild state in northern China, Ningxia wolfberry quality and efficacy for the history of physicians praised the “fruit flavor like dew, a discretionary extension of the” power. Nearly 600 years have developed into fine cultivars. Ningxia Yinchuan City and Zhongning County is the focus of origin. In recent years, many provinces and autonomous regions in the country were introduced in large quantities from Ningxia. Large-scale cultivation and trial cultivation were carried out in northeast, northwest, north China and Jiangsu and Zhejiang provinces. However, the pest species in this plant are numerous and harmful. Often rampant because of pests and the formation of large-scale production and poor quality. In wild conditions, insect population density is higher, often more than 10 kinds of mixed occurrence, since a host plant-specific insect fauna. Analysis is discussed below.
