马铃薯种薯经长时间窖藏,体内温度低,生理机能受到抑制,使种薯处于休眠状态。如果出窖即切块播种,往往出苗缓慢且不整齐,影响产量。所以,在播种前应进行种薯处理,打破休眠,以利提早出苗。种薯处理方法很多,常用的有困种和催芽两种。有的地方常合称这两种处理方法为困种催芽、见光催芽等。其实,两者是有区别的。困种是促使种薯尽快渡过休眠期的措施,催芽虽然也有相同作用,但更主要的是使种薯长出芽来,以促进植株各生育阶段提前。 Potato potato cellar after a long time, the body temperature is low, inhibition of physiological functions, the seed potato in a dormant state. If the cellar that is cuttings, often slow emergence and irregular, affecting the yield. Therefore, should be carried out before sowing seed treatment, breaking dormancy, in order to facilitate early emergence. There are many ways to deal with seed potatoes, two kinds of commonly used trapped species and germination. In some places, it is often said that these two kinds of treatment methods are trapped seedlings and see light and germination. In fact, there is a difference between the two. Sleepy species is to promote seedling as soon as possible through the dormant period of the measures, although the sprouting also has the same effect, but more important is to make seedling buds to promote the plant early stages of each growth stage.
