马铃薯种薯由于长期在冰冷的窑中贮存,薯内的生理机能因低温而受到抑制,仍处于强迫休眠阶段,如果一出窑就播种,往往会出苗缓慢,而且还不整齐,所以,种前进行催牙处理就显得很有必要。这样,可以促进种薯生理活化,以利提早上市。据我校试验,催芽播种比不催芽播种,出苗期可提前5—7天,而且,催芽长出的苗浓绿健壮、出苗整齐;未经催芽处理的,幼苗瘦弱无力,而且还出现缺苗断垄现象。那么,怎样进行催芽呢?根据我校几年来的经 Due to the long-term storage of potato seed in the cold kiln, the physiological function in the potato is inhibited by the low temperature and is still in the dormant stage of forced dormancy. If it is planted out of a kiln, the seedling tends to be sprouted slowly and not neatly. Therefore, Dental treatment is very necessary. In this way, can promote physical activation of seed, in order to facilitate early market. According to my school test, germination sowing than non-germination sowing, seedling can be 5-7 days in advance, and, sprouting grow thick green seedlings strong, neatly emerging; without germination treatment, thin and feeble seedlings, but also the emergence of lack of seedlings Broken ridge phenomenon. So, how to promote it? According to my school for several years
