包头市固阳县马铃薯新品种引进及适宜性评价

Introduction and Suitability Evaluation of New Potato Varieties in Guyang County of Baotou City

包头市固阳县近年来由于品种结构不合理、倒茬轮作不到位导致各种病害加剧,种植面积锐减。该试验从多地引入中早熟、中晚熟和晚熟3种熟期共计10个马铃薯品种,并对这些品种的适宜性进行评价,从而筛选出优质高产新品种。结果表明,中早熟品种"中薯5号"和"兴佳2号"产量高、商品性好,可推广种植;中晚熟组"希森6号"经济性状表现突出,可做薯条加工品种,"华颂7号"用途广泛、品质好、产量较高,可尝试推广种植。

In recent years,due to the unreasonable varieties structure and inadequate crop rotation,various diseases have intensified,the planting area of potato decreased sharply.In this experiment,10 potato varieties were introduced from many places,including middle early maturing,middle late maturing and late maturing,so as to evaluate the suitability of these varieties and screen new varieties with high quality and high yield.The results showed that Zhongshu 5 and Xingjia 2 had high yield and good marketability,which could be widely planted;the economic characters of Xisen 6 in the middle late maturing group were outstanding,it can be used as processing variety of French fries,Huasong 7 has a wide range of uses,good quality and high yield,so it could be planted tentatively.
