脱毒马铃薯的研究和推广,使马铃薯的产量和质量都得到了大幅度地提高,一跃成为一种比较重要的经济作物。近年来,脱毒马铃薯早熟栽培技术的推广,更使马铃薯的产值成倍增加。应广大读者的要求,在此简要介绍一下脱毒马铃薯的保护地早熟栽培技术。一、品种选择早熟栽培应选用结薯早、结薯集中、薯块整齐、商品率高的早熟品种如“鲁引1号”、“东弄303”等。事实上,在山东省各地无论采用哪种栽培形式(保护地或露地),都不能选用晚熟和中晚熟品种,否则会导致减产甚至绝产。此外,还应注意选用优质脱毒种薯,因为种薯脱毒与否,其产量和质量差别都非常大。
The research and popularization of virus-free potato has greatly improved the yield and quality of potato and has become a more important economic crop. In recent years, virus-free potato cultivation technology promotion, more so that the output of the potato doubled. At the request of readers, we briefly introduce the precocious cultivation techniques of virus-free potato. First, the selection of varieties of precocious cultivation should be used early knot tuber, tuber concentrated, tuber neat, high rate of commodity varieties such as “Lu Yin No. 1”, “East Lane 303” and so on. In fact, no matter what type of cultivation (protected or open field) is adopted in Shandong Province, late-maturing and middle-late maturing varieties can not be used, otherwise it will lead to the reduction of production or even the absolute loss of production. In addition, we should also pay attention to the selection of high-quality virus-free seed, because the detoxification of seed or not, the yield and quality differences are very large.
