The latest seed price and planting method of fresh white bark

White fresh skin, also known as white moss skin, eight strands of cattle, mountain peony and so on, is the root bark of Rutaceae perennial herbs and narrow leaves, mainly produced in Liaoning, Hebei, Sichuan, Jiangsu and other places. It has the effect of clearing heat and dryness, dispelling wind and detoxification, and the cultivation value is very high. Let's take a look at the seed price and planting method of white fresh skin.

How much is the white fresh skin seed per jin?

The price of white fresh skin seeds is about 800,1200 yuan per jin, but it varies according to the quality, origin and quantity of seeds. White fresh bark grows mostly on sunny hillsides, forest margins and sandy soil between low shrubs, hilly slopes or flat bushes or in grasslands or under sparse forests. limestone mountains are also common, have strong adaptability and like warm and humid environments. Like light, cold, drought, not waterlogging. In production, we mainly use seeds to propagate, first concentrate on raising seedlings, then grow for 1 ~ 2 years and then plant separately.

Sowing method of White fresh Bark

The main results are as follows: 1. Seedling selection and breeding land: White fresh bark seedling land should choose sandy loam flat or gentle slope land with sufficient sunshine, loose soil and good drainage, low-lying land prone to waterlogging, saline-alkali land or heavy clayey land is not suitable, it is best to have the condition of drainage and irrigation.

2. Autumn sowing method: autumn sowing of white fresh bark is carried out from the first ten days of October to early November, and the seeds are mixed with 3 times fine river sand, with a dosage of about 20 grams per square meter, covered with 1 centimeter of fine soil, and then covered with Pinus tabulaeformis or larch needles about 1cm.

3. Spring sowing method: spring sowing of white fresh bark is carried out from late April to mid-May, and the seeds are mixed with 3 times fine river sand, with a dosage of about 20 grams per square meter, covered with 1 cm fine soil, and then covered with Pinus tabulaeformis or larch needles 1 cm or 2 cm.

The planting method of White fresh Bark

The main results are as follows: 1. The site selection: the transplanting land of fresh bark should choose the gentle slope land with deep soil layer and good drainage, and the mountain area can make use of sunny hillside wasteland, orchard and artificial young forest. It can also be cultivated in the low shrub space of tussah silkworm workshop and hazelnut orchard.

2. Soil preparation: White fresh bark planting land is combined with deep ploughing, the mu of rotten farm manure is 1500 to 2000 kilograms, and after raking fine, it is made into a border with a width of 100 centimeters and 1200 centimeters, and the length is determined according to the topography, generally 20 to 30 meters is suitable, and the operating path between the beds is 40 centimeters wide.

3. Transplanting: the planting depth of fresh bark is determined according to the root size of the transplanting seedlings, the terminal buds of the seedlings are placed upward in the transplanting trough, the terminal buds are 1cm lower than the border surface, and the root system stretches the plant distance between 35cm and 40cm. Cover the soil, flatten the border surface after covering the soil, and add a little shock pressure.

4. Weeding: in the first two years of transplanting, the seedlings were small and weeded 3 or 4 times a year in line with the principle of weeding on sight. After 3 years, the plant has grown very tall, the grass damage has little effect on it, and the relative times of weeding is reduced.

5. Fertilization: White fresh bark was topdressing twice in late May and early June, applying 800-1000 kg farm manure per mu or 8-10 kg urea per mu, and the Beginning of Autumn sprayed 0.3% 0.5% potassium dihydrogen phosphate foliar fertilizer once.
