在榨菜采收期,经常可以发现其瘤状茎大小差别很大。有时同一田块中瘤状茎大的有400克以上,小的不到50克,而且这种偏大或偏小的瘤状茎比例还较高。瘤状茎大小差异不仅影响单位面积产量,而且直接影响产品销售。1.发生原因发生瘤状茎大小不匀的原因是多种多样的,可能是一个原因,也可能是两个或两个以上原因。(1)秧苗大小或秧苗生长速度不一由于榨菜苗龄较长(一般在35天左右),在秧苗生长过
Tuber harvested in the harvest, often can be found in the tumorous stem size vary widely. Sometimes in the same field tubercle large with more than 400 grams, less than 50 grams of small, and this large or small proportion of tumorous stems is also higher. Tuber size differences not only affect the yield per unit area, but also directly affect product sales. 1. Occurrence of tumor stem size uneven occurs due to a variety of reasons, may be a reason, it may be two or more reasons. (1) Different seedling size or seedling growth rate Due to the longer seedling age (usually around 35 days), the growth of seedlings
