How to plant gold without changing it?

Jinbuxian, also known as Panax notoginseng, is well-known at home and abroad for proprietary Chinese medicine "Yunnan Baiyao" and "Pian Zi Huang", that is, it is made with Jinbuxin as the main raw material. So how do you grow it without changing it?

I. selection of sites

It is suitable to choose gentle slope land with good drainage and humus soil or sandy loam rich in organic matter with a slope of 5 to 15 degrees. It is appropriate to use corn, peanuts or beans in front of farmland, and do not use Solanaceae as pre-cropping. Selected plots should be fallow for one to half a year and ploughed many times, with a depth of 15cm to 20cm to promote soil weathering. Where there are conditions, you can spread grass and burn soil before turning the land or apply 100 kilograms of lime per mu for soil disinfection. For the last time, 5000 kg of fully mature barnyard manure and 50 kg of cake fertilizer were applied per mu, leveling and fine ploughing, making the border, the border was to the south, the border width was 1.2 to 1.5 meters, the border spacing was 50 to 150 centimeters, the border length was determined according to the topography, the border height was 30 to 40 centimeters, and the border was blocked with bamboo poles or sticks to prevent the border from collapsing.

Second, sowing seeds

1. Seed selection treatment: from October to November every year, select the full shade ripe red fruit from 3-year-old 4-year-old plants, pick it, put it on bamboo sieve, rub off the peel, wash it, and dry the surface moisture. The seeds were soaked in 65% Dysen zinc 400x solution or 50% topiramate 1000 times solution for 10 minutes. Jinbu seeds are easy to lose their vitality after drying, so they should be preserved with picking and sowing or stratification treatment.

two。 Sowing: print with tools, sow on demand with a row spacing of 6 cm × 5 cm, then evenly spread a layer of mixed fertilizer (mixed with rotten farm manure or mixed with other fertilizers), and cover the border with a layer of straw to keep the border surface moist and inhibit the growth of weeds. 70, 000 ~ 100000 seeds per mu, equivalent to 10 ~ 12 kg of fruit. If the method of covering silver-gray plastic film is adopted after sowing and watering, it can obviously increase production and save water and fertilizer.

3. Seedling management and transplanting: when the weather is dry, water should be watered frequently, stagnant water should be discharged in time after rain, and weeding should be done regularly. Topdressing at seedling stage is usually based on phosphate fertilizer, usually topdressing for 3 times, the first time after the emergence of seedlings in March, and the last two times in May and July respectively. The transmittance of the canopy at the 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 at the same time. When taking root, strictly prevent damage to root strips and spores. When selecting seedlings, disease, injury and weak seedlings should be removed and cultivated at different levels.

III. Field management

1. Weeding and soil cultivation: Jinbu is not replaced by shallow root plants, and the root system is mostly distributed in the surface layer of 15 cm, so it is not suitable for mid-ploughing so as not to damage the root system. After the seedlings are unearthed, the weeds on the border should be removed in time, and the soil should be cultivated when the roots and roots are found to be exposed to the ground.

two。 Watering, drainage: in the dry season, often drench water to keep the border surface moist, should be sprayed when drenching, can not be drenched, otherwise cause plant lodging. In the rainy season, especially after heavy rain, stagnant water should be removed in time to prevent the occurrence of root rot and other diseases.

3. Build a shed and adjust the light transmittance: the gold does not change the shade, artificial cultivation needs to build a shed for shade, the height of the fence is 1.5-1.8 meters, and a side shed is set up around the shed. The shed materials are made of local materials, generally using wood or cement precast strips as shed columns, grid tops drawing iron wires as crossbeams, and then woven into squares with bamboo to lay the roof of the shed. The amount of light transmission in the greenhouse has a close effect on the growth and development of gold. Too little light transmission, weak plants, prone to diseases and insect pests, and less blossom and fruit.

4. The principle of "many times and a small amount" should be grasped when gold is not changed for topdressing. Generally, after the seedlings are germinated and unearthed, plant ash is applied 2 times for 3 times, with 50-100 kg per mu to promote the growth of seedlings. The mixed organic fertilizer (stable manure and plant ash 2:1) was applied once from April to May, with 2000 kg per mu and 15 kg superphosphate in the remaining plot to promote the fullness of fruit. After clearing the garden in winter, 2000-3000 kg of mixed fertilizer was applied per mu.

Jinbu is suitable for the cool climate in winter and summer, and is not resistant to severe cold and heat, so it is planted in only a small number of places in the southwest.
