The planting prospect of the latest heavy building

Chong Lou, also known as Liliaceae, Bai Gan Sui, Zhi Hua Tou, Golden Thread, is the rhizome of Yunnan Zhonglou, a lily plant, hard and brittle, with a white cross-section, with the effects of heat-clearing and detoxification, relieving swelling and relieving pain, cooling the liver and settling shocks. for ulceration carbuncle, sore throat, poisonous snake bite, fall sore, wind convulsions and other symptoms, let's take a look at the planting prospect of the heavy building!

The planting prospect of heavy building

Chong Lou is a wild medicinal material. With the continuous decrease of wild resources year by year and high medicinal value, it leads to serious folk excessive digging. Due to the long growth cycle of medicinal parts, the exploitable amount of wild resources is facing depletion. Recently, the market has been stable at high prices. Although the supply of goods on the market is not selling very fast, due to the reduction of resources, the high price market has not been reversed. Now the price of domestic unified goods in the market is about 780 yuan, and the selected loading is about 870 yuan. Between 280,290 yuan for imports. At present, artificial planting is successful, but there is little supply in the market, the development trend is slow, it is still not large-scale, and the planting cost is also high.

Planting conditions of heavy buildings

1. Geography: wild heavy buildings grow in valleys, streams and shady wetlands under broad-leaved forests at an altitude of 700m to 1100m.

2. Soil: the heavy building is most suitable to grow in permeable slightly acidic humus soil or fertile sand, but cannot grow in alkaline soil or clay, and the soil with heavy viscosity, easy stagnant water and consolidation should not be planted.

3, moisture: heavy buildings like cool, wet, moderate moisture environment, afraid of both drought and stagnant water, soil water content is too low, easy to cause water loss of stems and leaves, root system dry and die, while too high is prone to diseases and insect pests, roots rot.

4. Temperature: the heavy building plant is more cold-tolerant, and there is no freezing damage at low temperature. The temperature from late February to early March is 5 ℃, and even the lowest temperature is 2 ℃. When the temperature is 1: 2 ℃, the suitable temperature for seed germination, root growth and terminal bud germination is 18: 20 ℃, 20 ℃, 16: 20 ℃, and 14: 18 ℃.

5. Light: Chong Lou is a shade-loving plant, likes oblique or astigmatism, avoids strong light, growth requires shading environment, strong light will wither leaves, generally seed germination and seedling stage requires better shading, and the first two years of maturity should appropriately reduce shading and increase light, which is beneficial to the accumulation of secondary metabolites and dry matter.

Planting technology of heavy building

1. Seedling replenishment: interseedling is usually carried out in the direct seeding field in the middle and last ten days of May, and the pond is checked to make up the vacancy at the same time. The seedlings should be watered before the seedlings are watered, and the seedlings should be plucked with wood pry, and the root water should be watered when filling the seedlings, so as to make full use of the seedlings to ensure the whole seedling and sufficient density.

2. Intermediate ploughing and weeding: heavy buildings require loose soil and weak aboveground growth, so special attention should be paid to loosening soil and weeding. Generally from late May to early June, there are many torrential rains and the soil is easy to harden, so it is necessary to drain and prevent waterlogging in time, ploughing and loosening the soil frequently, and pay attention to the removal of weeds at any time.

3. Timely shading: heavy buildings like shading and fear strong light, and the whole growth period should be 40-50%, so shading measures should be taken after seedling emergence and transplanting. It is best to use a sunshade net where there are conditions, and the method of planting branches to shade can be adopted where there are no conditions. You can also try corn shading, but we should pay attention to the density and the way of covering.

4. Topdressing and cultivating soil: the heavy building usually has the growth law of blooming above and expanding the tuber below. Generally, it grows fastest from mid-June and late June to the end of August. Forced fertilizer must be re-applied in the first ten days of June. 2000-3000 kg of cow and sheep stable manure or soil fertilizer per mu. 20-30kg of calcium plus calcium is applied to the root, and the soil on the wall must be loose, keep moisture, and there is no stagnant water at the bottom of the ditch.

5. Harvest treatment: before and after falling seedlings in autumn, that is, from November to December to March of the following year, the tubers can be harvested. Most of the tubers grow in the topsoil layer and are easy to dig, but attention should be paid to keeping the tubers intact. First cut off the stems and leaves, then dig from the side with a hoe, dig out the tubers, shake off the soil, rinse with clean water, slice 2-3mm thick, and dry. On cloudy days, it can be dried over a low heat of about 30 ℃.
