1播前准备机械整地党参是地下根茎作物,对土壤空隙度要求较高。前茬作物收获后,667米~2施农家肥10吨以上。采用东方红-250型拖拉机配套二铧翻转犁,进行机械化作业,耕深28～30厘米。结合深翻,土壤晾晒10～15天,使下层土壤与有机肥均匀混合。晒好后,用旋耕机械旋耕,并打耱保墒。精选种子选用当年新种子,清除杂、烂、秕种。播种前要晒种3～5天,打破种子的休眠期,要求种子净度≥98%,发芽率≥98%。
1 sowing before mechanical preparation site Codonopsis rhizome underground crops, the soil porosity higher. After the harvest of the former crop, 667 m ~ 2 farmers fertilizer more than 10 tons. The use of Dongfanghong-250 tractors supporting the second Hua flip plow, mechanized operations, deep plowing 28 to 30 cm. Combined with deep turning, soil drying 10 to 15 days, so that the lower soil and organic fertilizer evenly mixed. After drying in the sun, use a rotary tillage machine and pound the soil moisture. Selection of new seeds of the year selection of seeds, remove miscellaneous, rotten, 秕 species. Sowing before planting 3 to 5 days, breaking the seed dormancy period, requiring seed purity ≥ 98%, germination rate ≥ 98%.
