我省地处东南沿海,气候温和、雨量充沛,有利紫云英生长,但春雨多、日照少、湿度大,致病虫为害严重.加上土壤多有缺钾、磷和缺硼、钼,因而紫云英种子产量很低,一般亩产只有30斤左右.而主要种植紫云英的闽西北山区,亩产更低,所以群众不愿留种,致使年年向外省调进大量种子.为此,我们从1978年起,就在尤溪县开展紫云英留种栽培技术研究,并提出一套以防治病虫害为中心的留种高产技术,在当地进行了生产示
The province is located in the southeast coast, the climate is mild, abundant rainfall, favorable growth of Astragalus, but more spring and rain, less sunshine, humidity, causing serious pests and diseases.With more soil potassium deficiency, phosphorus and lack of boron, molybdenum, As a result, the seed yield of Astragalus sinicus is very low, and the average yield per mu is only about 30 kg, while in the mountainous region of northwestern Fujian where mainly cultivated Astragalus mongholicus is, the yield per mu is lower, so the masses are reluctant to stay seed, resulting in the transfer of large quantities of seeds to other provinces every year. To this end, we have studied the cultivation techniques of Astragalus sinicus in Youxi County since 1978, and put forward a set of high-yielding techniques that focus on the prevention and control of pests and diseases. We have carried out production demonstration in this area
