当前大部份马铃薯都是切块播种。但切块播种,如果不加选择,容易发生烂籽、染病,缺苗断垄,严重影响产量的提高。为了解决这个问题,我们从1975年开始,连续在丰镇县部份社队进行播种薯块顶部的试验。具体做法是,先在窖口选择无病、表皮光滑、没有裂缝、中等大小的薯块,长形薯切下顶部2/5做种薯,圆形薯切下顶部1/3做种薯,切好的种薯用草木灰拌种,防止病菌从破口侵入,并晾晒数日再播种。
Most of the current potato is planted. However, dicing seeding, if no choice, prone to rotten seeds, disease, lack of seedlings off ridge, seriously affecting the yield increase. In order to solve this problem, we started from 1975 and consecutively conducted tests on the tops of potato cakes in some commune brigades in Fengzhen County. The specific approach is to first choose in the mouth of celiac disease-free, smooth skin, no cracks, medium-sized potato, cut the top 2/5 to do the kind of potato, potato, Chopped seed with grass ash seed dressing to prevent bacteria from breaking through intrusion, and drying a few days and then planting.
