过对脱毒荷兰马铃薯原原种（品种名：Ｆａｖｏｒｉｔａ拉丁名：ＳｏｌａｎｕｍｔｕｂｅｒｏｓｕｍＬ．）在播种前进行的两种不同催芽处理的对比试验，发现湿沙催芽的种薯生长势及单株产量明显高于普通散射光催芽的种薯。湿沙催芽对种薯地上部生长的作用主要表现在：增加了地上部茎数；提高了茎的生长速率（单位时间内生长量），植株高度明显高于普通催芽的种薯；主茎叶龄的增长速率虽然相同，但经过湿沙催芽种薯主茎叶龄比未经湿沙埋藏处理的提前生长一片叶。湿沙催芽对种薯地下部分生长的作用主要表现在提高了单株结薯数和单个薯块的均匀度。在脱毒马铃薯种薯生产序列中（原原种→原种→生产种）湿沙催芽对马铃薯原种的薯块形体和产量具有积极的意义。
A comparative experiment on two different germination treatments of detoxified Dutch potato (Solanum tuberosum L.) under the name of Favorita lappa was conducted. It was found that the growth potential and yield per plant of the detoxification seed potatoes were significantly higher Ordinary scattered light germination of the seed potato. The effects of wet sand astringents on shoot growth were mainly as follows: the number of shoots on shoots was increased; the growth rate of stems (growth per unit time) was increased; the height of plants was significantly higher than that of common germination; Although the growth rate of the same age, but after the wet sand germination of main stems and leaves than the wet sand without burial treatment advance a leaf. Wet sand germination on the growth of part of the seed mainly in the role of increased tuber number per plant and individual tuber uniformity. In the process of virus-free potato seed production (original seed → original seed → production seed), wet sand astringency has a positive effect on potato bulk and yield of potato seed.
