Seedling raising technique of Panax notoginseng

Panax notoginseng is a traditional Chinese medicine, its rhizome can be used as medicine after drying, it has the effect of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, and mainly treats hemoptysis, hematemesis, hematochezia, traumatic bleeding, swelling and pain and so on. Panax notoginseng is propagated by sowing, and its seeds are easy to lose their vitality after drying, so they should be sown with picking. Let's take a look at the fry technology of Panax notoginseng.

1. Land selection and preparation

The gentle slope with low sloping land and good drainage has been selected as the seedling land, and the previous crops had better be corn, peanuts, soybeans and other crops, but Solanaceae can not. After selecting the seedling site, leave it idle for 3-6 months, cover it repeatedly to promote soil weathering, and if there are sufficient conditions, you can also apply plant ash or lime powder for disinfection. During the last ploughing, 4000-5000 kg of rotten farm manure per mu was used as base fertilizer, raked fine and leveled to make a bed, and the width and height of the bed depended on the topography.

2. Seed treatment

When the fruit is ripe every year, the fruit of the plant growing for 3-4 years is picked, peeled off, washed, the surface water is dried, and then the seeds are soaked in low concentration of Dysen zinc or methyl thiophanate solution for 8-10 minutes. The seed vitality of Panax notoginseng is weak, and it will lose vitality after drying, so it is not suitable to keep it, so do well with picking and sowing.

3. Sowing seeds

Sowing adopts the method of on-demand sowing, opening holes according to the row spacing of 5 × 6cm on the border surface, sowing 3-4 seeds in each hole, covering a layer of shallow soil after sowing, and then evenly spreading a layer of compound fertilizer on the soil, covering with a layer of weeds, can prevent the growth of weeds. Using 7-100000 seeds per mu, about 10-12 kg, watering once after sowing, mulching with plastic film can obviously conserve water, save fertilizer and increase yield.

4. Seedling stage management

Remove the plastic film and cover grass in time after emergence, and in case of dry weather, we should often irrigate, keep the soil moist, keep the water needed for the seedlings, and drain and prevent waterlogging in time after rain to avoid root rot of the seedlings. Weeding in time in the seedling stage, in addition to water management, timely topdressing and promoting the growth of seedlings is also necessary. Phosphate fertilizer is the main topdressing at seedling stage, generally topdressing 3 times, the first time in Miaoqi, the second in May, the third in July.

The above is the introduction of Panax notoginseng seedling technology, hope to help you, want to know more planting knowledge, please pay attention to us.
