当前,人参普遍采取鲜籽撒播方法育苗。存在的主要问题是:①出苗不齐。头一年只能出60%,第二年出30%,第三年才出齐;②苗子大小不匀。③可用的苗少(单支重0.5钱以上),无用的苗多。为了实现一次播种,一次出齐苗和增加可用苗比例,1975年我们在新宾县夹河北大队参场,进行了干籽点播试验,试验面积750帘(每帘为10平方米)。1978年秋(三年生苗时),平均单帘产量为35.6斤.比采用鲜籽撒播育苗增产48.3%。可用苗占总苗数
At present, ginseng generally adopt seedling sowing methods. The main problems are: ① emergence of missing. Only 60% in the first year, 30% in the second year, the third year before Qi; ② uneven seedling size. ③ available seedlings less (single weight 0.5 or more), useless seedlings and more. In order to achieve a sowing time, once out of Qi Miao and increase the proportion of available seedlings in 1975, we Binbei Brigade in Xinbin County participating field, conducted a dry seed-on-demand test, the test area of 750 screens (each curtain is 10 square meters). In the autumn of 1978 (when three-year-old seedlings were born), the average single-leaf yield was 35.6 kg, 48.3% more than the seedlings raised with fresh seeds. Available seedlings accounted for the total number of seedlings
