种子是人参繁殖的主要材料。种子质量的好坏对人参出苗率高低、长势好坏以及产量有很大影响。良种出壮苗,壮苗才高产。留种:人参留种不是见参开花打籽就留种。实践证明,人参生产约6年为一个周期。在这个周期中,最好采一次种子,即在4—5年生的参田植株上留一次种子。因为4—5年生的人参是长得最壮时期,所产的种子充实饱满。用这样的种子播种后出苗整齐。除上述留种的人参外,对于不宜留种的人参植株一律在6月上旬开花之前掐掉花蕾,减少营养消耗。3年生的人参也能开花、结果,所产的种子叫“娃娃”种子,胚发育不好,未能充分成熟。如果用来播种则多数不出苗或出苗不整齐,且苗很弱。因此,对于3年生的人参植株所有的花蕾,要坚决掐掉,不可留种。对于当年要起收的商品人参,为了保证质量和产量,也要全部去花去蕾不留种。 Seeds are the main material for ginseng breeding. The quality of seeds on the ginseng emergence rate, growth and yield and have a significant impact. Seed out of strong seedlings, seedlings only high yield. Stay species: ginseng seed is not seen to see the flowering seeds to stay seed. Practice has proved that about 6 years of ginseng production for a cycle. In this cycle, it is best to pick the seed once, ie leave the seed on the 4-5 year-old plant. Because 4-5 years of ginseng is the strongest growth period, full of seeds full. After sowing with such seeds emerge neatly. In addition to the above-mentioned ginseng seeds, ginseng plants that are unfavorable for species should be pinched off their buds before blooming in early June to reduce their consumption of nutrients. 3-year-old ginseng can flowering, the result, the seed produced is called “doll” seeds, embryo development is not good, not fully mature. If used to sow the majority of seedlings or seedlings are irregular, and the seedlings are weak. Therefore, for 3-year-old ginseng plants all the buds, must be firmly pinch out, can not stay species. Ginseng for the goods to be picked up from the same year, in order to ensure the quality and yield, but also to spend all the time to spend without buds.
