马铃薯中联红引种试验

STUDY ON INTRODUCTION OF POTATO ZHONG LIANHONG

从中原二作区引进中联红品系，在内蒙古商都县进行喷灌圈种植试验，结果表明：中联红生育期在当地无霜期之内；并且无沾染x、Y、卷叶病毒与晚疫病，较轻度感染环腐病、早疫病，植株健康；株高与鲜重在整个生育时期均高于其他4个微型薯品种；中联红的主茎数最多，而分枝数最少；匍匐茎分布均匀，层数一般都达到2层～3层；匍匐茎个数顺序为：中联红〉夏波蒂〉大西洋〉费乌瑞特〉克新1号，且粗壮、长；成熟期测产，比大西洋、夏波蒂、费乌瑞特、克新1号品种分别增产19．05％、0．41％、25％、38．89％；中联红薯型良好，商品率高，单株结薯数为克新1号的1．7倍。中联红品系淀粉含量最高，为19．5％；还原糖、可溶性糖含量顺序均为：克新1号〉中联红〉费乌瑞特〉夏波蒂〉大西洋。因此，中联红品种适于在内蒙古一河北坝上地区推广种植。

The potato Zhong Lianhong was introduced from the Central plains area and planted in irrigation circles in Shang Du of Inner Mongolia. The experimental results showed ： the growth period of Zhong Lianhong was among the local frost - free period, and it was not contaminated by potato x virus, y virus, leaf curl virus and late blight disease, but infected ring rot and early blight disease slightly. Height and fresh matter during the whole development stage were higher than the other four potato varieties, the numbers of main stems were highest, but branches were lowest. The creeping stem were well distributed and the layers generally reached 2 -3 layers, and the rule of the number was ： Zhong Lianhong 〉 Shepody 〉 Atlantic 〉 Fei Wu ruite 〉 Ke Xin 1, and the branches were strong and long; the yield of Zhong Lianhong were 19.05%, 0.41%, 25%, 38.89% more than Atlantic, Shepody, Fei Wu ruite, Ke Xin 1 respectively. Zhong Lianhong has high quality, good model, grams per chips were 0.7 times more than Ke Xin 1. The starch content of Zhong Lianhong was the highest, it was 19.5% The order of soluble sugar and reducing sugar content was： Ke Xin 1 〉 Zhong Lianhong 〉 Fei Wu ruite 〉 Shepody 〉 Atlantic. Therefore, it was suitable to introduce potato varieties Zhong Lianhong to plant in Inner Mongolia and He Bei high plain.
