How much is the market price of "sea cucumbers on land" per jin? This kind of easy and high yield!

Rhizoma Polygonatum is a common traditional Chinese medicine, which has the effects of tonifying the spleen and moistening the lungs, so it is widely used as a medicinal material. At present, artificial planting is also being carried out in many areas. How much is the market price of Polygonatum? How to grow high yield?

First, Huang Jing introduction:

1. What are the producing areas of Polygonatum?

Polygonatum polygonatum is mainly produced in Zhejiang, Anhui, Guizhou, Yunnan, Sichuan, Guangxi and other places in China. Polygonatum polygonatum is mainly produced in Shaanxi, northeast coastal areas and Gansu and other places. Polygonatum is mainly produced in Yunnan, Guizhou, Sichuan, Guangxi and other places.

2. What kinds of Rhizoma Polygonatum?

Yunnan Polygonatum, Polygonatum polygonatum, Rehe Polygonatum, curly leaf Polygonatum, rose yellow essence, long leaf yellow essence, naked flower yellow essence, pair leaf yellow essence and so on.

Second, how much is the market price of Polygonatum polygonatum?

The market price of Polygonatum polygonatum is relatively close to the people, generally about 15 to 20 yuan per jin, and good quality about 40 yuan per catty, but the price will also change to a certain extent due to the factors of origin, market, variety and quality. For example, the market price of chicken head Polygonatum is about 1315 yuan per jin, the market price of fine yellow essence is about 1820 yuan per jin, and the market price of fine yellow essence is more than 40 yuan, so the specific price still needs to consult the local market.

Third, how to grow Polygonatum with high yield?

1. Land selection and preparation:

Huang Jing likes to grow in a shady and wet environment, so when selecting land, try to choose slopes that are not sunny for planting. After selecting the land, it is necessary to turn it deeply and apply 1500-2000 kg of organic fertilizer per mu for subsequent planting. In addition, in order to facilitate later drainage and daily management, a ditch with a width of 1.5m and a spacing of about 20cm can be dug to prepare for later management.

2. Sowing:

(1) sowing time: around August or March

(2) sowing method: Polygonatum polygonatum can be sowed by direct seeding or tuber transplanting, in which direct seeding is the simplest method, only need to sow the seeds on the seedling bed at reasonable intervals, and then cover a layer of soil. Tuber transplanting is to dig out a part of the tuber in March, then divide it into nodes, dry it and place it evenly on the soil, then cover it with thin soil and cover it with a thin film or straw to germinate.

3. Seedling management:

In order to make Polygonatum seeds germinate quickly, the straw or film should be removed before emergence, and the dense or weak seedlings should be removed when the seedling height is about 9cm, and can be transplanted after a year.

4. Field management:

(1) weeding in mid-tillage: weeds grow after Polygonatum polygonatum grows for a period of time, so weeds should be weeded once in April, June, September and November every year, and soil should be cultivated in combination with soil dryness to promote seedling growth.

(2) timely fertilization: Polygonatum does not have high requirements for fertilizer, but it does not mean that it does not need fertilizer, so calcium fertilizer and soil miscellaneous fertilizer can be properly applied when loosening soil and weeding, generally after the first three times of intertillage. Apply 1500 kg of soil miscellaneous fertilizer, 5 kg of calcium fertilizer and 50 kg of cake fertilizer per mu to ensure adequate nutrients.

(3) Prevention and control of diseases and insect pests: leaf blight, black spot, leaf spot, grub and other diseases and insect pests will occur during the growth of Polygonatum polygonatum, so control measures must be taken during planting. General leaf blight can be controlled with 65% zinc wettable powder 500 times, black spot can be sprayed with Bordeaux solution, and grubs can be irrigated with 75% phoxim EC.

5. Harvest and processing:

Rhizoma Polygonatum is generally harvested in spring and autumn, and the quality of harvest in autumn is the best. When picking, dig the rhizome as far as possible, remove the upper roots, wash off the mud, steam until oily, take out the sun or dry.

Generally speaking, Polygonatum polygonatum is not expensive and the planting technique is simple, so it is generally easy to feed. If it is planted for the first time, it can be planted in accordance with the above method to achieve high yield.
