笔者于1985～1986年,进行马铃薯田间块速繁殖试验。1985年繁殖系数达6880倍,1986年繁殖系数达16933倍(繁殖系数以10克以上的薯块个数计算)。一、快速繁殖方法 (一)选种选择抗或高抗晚疫病的高产品种、品系、株系。于大春季开花期选生长势强、无病毒和细菌危害症状的植株作好标记,在终花期收挖。收挖时挑选高产单株,淘汰尖头、龟裂、畸形、较小的薯块,把选出的较大薯块放在室内见光处,培育绿色短壮芽。
The author from 1985 to 1986, the potato field block breeding test. In 1985, the coefficient of propagation reached 6,880 times, and the coefficient of reproduction in 1986 reached 16,933 times (the coefficient of propagation was calculated as the number of potato pieces of 10 grams or more). First, the rapid breeding methods (A) Selection of resistant or high resistance to late blight selection of high yield varieties, strains, strains. In the spring flowering period, choose a strong growth potential, no virus and bacterial hazard symptoms of plants marked, dig in the final flowering. Excavated high-yielding single plant selection, out of sharp, cracked, deformed, smaller potato pieces, the larger potato block on the room to see light, cultivate green short strong buds.
