马铃薯是青海五大粮食作物之一,为了加快提高马铃薯生产的单位面积产量及经济效益和社会效益,建设好种薯基地具有特别重要意义。根据马铃薯生物学特性,结合生产实际谈点建设种薯基地浅见: 1 掌握马铃薯生物学特性。马铃薯是无性繁殖作物,喜欢气候凉爽,但又怕严寒霜冻,更忌炎热高温,需水量高于小麦、玉米等作物,最适宜的土壤水分为其最大持水量的60—80%,是喜光作物,最适宜表土深厚、疏松,排水通气良好和富含有机质的土壤里生长。但马铃薯种薯退化较快,据研究
Potato is one of the five major food crops in Qinghai. In order to speed up the yield per unit area and economic and social benefits of potato production, it is of special importance to build a good base of potato. According to the biological characteristics of potato, combined with the actual production of talk about the construction of seed potato base see: 1 to master the biological characteristics of potatoes. Potato is a vegetative crop, like the cool climate, but afraid of cold frost, but avoid hot temperatures, water demand is higher than wheat, corn and other crops, the most appropriate soil moisture for its maximum water content of 60-80%, is the hi light crops , The most suitable topsoil deep, loose, well-drained aerated and organic-rich soil growth. However, potato seed degeneration is faster, according to research
