Can I plant Sanqi in Fuxin, Liaoning?

Panax notoginseng can't be planted in Fuxin, Liaoning Province. Panax notoginseng is very picky about its growing environment, preferring warm, shady and wet environment, fearing cold and heat, and water. The soil is loose red soil or brown red soil, slightly acidic; The annual average temperature is 16. ~ 19.3℃. If the temperature lasts for 3-5 days and is above 3℃ during the growth period, plants are prone to disease. Dongpo is suitable for cultivation, and the slope is 5-15. Planting in low-lying land is prone to root rot.

cultivation techniques of panax notoginseng

1. land selection and land preparation: gently drained land with a slope of 5-15 degrees, humus soil or sandy loam rich in organic matter should be selected. Maize, peanuts or beans are suitable for large-scale planting of Panax notoginseng in front of farmland, and solanaceae should not be used as the previous crop. When the plot is selected, it should be fallow for one to six months and ploughed for many times, with a depth of 15-2 cm, so as to promote soil weathering. Where conditions permit, we can spread grass and burn soil or apply 1 kilograms of lime per mu before turning over the land for soil disinfection. For the last time, 5, kilograms of fully decomposed manure and 5 kilograms of cake fertilizer were applied to each mu, leveled and cultivated, and the border was made. The border was 1.2-1.5 meters wide and 5-15 cm apart. The border length depended on the terrain, and the border height was 3.

2. Breeding method: Breeding with seeds.

(1) seed selection and seed treatment: from October to November every year, select the full-shaded, mature and red fruits of 3-4-year-old plants, pick them, put them in a bamboo sieve, rub off the peel, wash them and dry the surface moisture. Soak the seeds with 8 times solution of new high-fat film for 1 minutes for disinfection (which can be mixed with seed coating agent), so as to repel underground diseases and insect pests, isolate virus infection, not affect the function of germination and imbibition, strengthen respiratory intensity and improve seed germination rate. Panax notoginseng seeds are easy to lose vitality after drying, so they should be collected and sown or preserved by stratification.

Sowing: scribe lines with tools, sow seeds at a spacing of 6 cm× 5 cm, then evenly spread a layer of mixed fertilizer (mixed with decomposed farm manure or other fertilizers), and cover the border with a layer of straw to keep the border moist and inhibit the growth of weeds, with 7,-1, seeds per mu, equivalent to 1-12 kilograms of fruits.

if the method of covering with silver-gray plastic film after sowing and watering is adopted, it can obviously increase production and save water and fertilizer.

seedling management and transplanting: when the weather is dry, it should be watered frequently, and the accumulated water should be drained in time after the rain, and weeding should be carried out regularly. Topdressing at seedling stage is usually mainly phosphate fertilizer, usually topdressing for three times, the first time after the seedlings are fully grown in March, and the last two times in May and July respectively. The light transmittance of canopy at seedling stage should be adjusted according to the change of light intensity in different seasons. Panax notoginseng seedlings are transplanted after one year, usually from December to January of the following year. It is required to pick up seedlings, select seedlings and transplant them. When rooting, prevent damage to root strips and spores. When selecting seedlings, the diseased, injured and weak seedlings should be eliminated and cultivated in different grades. Panax notoginseng seedlings are divided into three levels according to the size and weight of roots: 1, roots weighing more than 2 kg are the first level; Thousands of roots weighing 1.5 ~ 2 kg are Grade II; Below 1.5 kg is level 3. Transplanting row-to-row spacing: 18 cm× 15 ~ 18 cm for the first and second grades; Level 3 is 15cm× 15cm.

3. Field management

Weeding and ridging: Panax notoginseng is a shallow-rooted plant, and its roots are mostly distributed in the surface layer of 15 cm, so it is not suitable for intertillage to avoid damaging the roots. After the seedlings are unearthed, weeds on the border should be removed in time. At the same time of weeding, if roots and roots are found to be exposed to the ground, soil should be cultivated.

water spraying and drainage: in the dry season, water should be sprayed frequently to keep the surface of the border moist, and it should be sprayed during water spraying, not splashed, otherwise the plants will fall down. In the rainy season, especially after the heavy rain, the accumulated water should be removed in time to prevent root rot and other diseases.

scaffolding and light transmittance adjustment: Sanqi is fond of shade, and artificial cultivation needs to be shaded by scaffolding, with the grid height of 1.5 ~ 1.8 meters, and side sheds are set up around the shed. The shed materials are made from local materials. Generally, prefabricated rows of wood or cement are used as shed columns, iron wires are pulled at the top of the grid as beams, and bamboo is woven into squares to lay the roof of the shed. The amount of light transmission in the shed has a close influence on the growth and development of Panax notoginseng. Too little light transmission, thin plants, easy to occur pests and diseases, and less flowering and fruiting; When the leaves turn yellow due to excessive light transmission, they are prone to early wilting. Generally, the principle of "sparse before, dense in the middle and sparse after" should be mastered, that is, the light transmittance is 6% ~ 7% in spring, slightly smaller in summer, 45% ~ 5%, and gradually expanded to 5% ~ 6% when the temperature turns cool in autumn.

topdressing: the topdressing of panax notoginseng should follow the principle of "multiple times and small amount". Generally, after sprouting, plant ash is applied 2-3 times, with 5-1 kg per mu to promote the growth of seedlings. From April to May, the mixed organic fertilizer (stable manure, plant ash 2:1) was applied once, with 2 kg per mu, and 15 kg of calcium superphosphate was added to the seed-reserved plots to promote fruit fullness. After clearing the garden in winter, 2

-3 kg of Hefei will be applied per mu.

bolting: in order to prevent unnecessary consumption of nutrients and supply underground roots for growth, when bolting occurs in July, all bolting is removed, and the medicinal herb Gendaling is sprayed on the leaves, so that the photosynthetic products (nutrients) on the leaves are transported to the roots, the nutrient conversion rate and soil loosening ability are improved, the roots are rapidly expanded, the medicinal content is greatly improved, and the yield of Panax notoginseng is increased. It should be done in sunny days.
