How many Jin of Dictamni bark can be produced per mu, with planting method and time.

After 3-4 years of artificial cultivation, it can produce 300-350 kg of fresh dried Dictamni (2.8-3.3 kg of fresh roots can produce fresh dried Dictamni 1 kg) per mu. 1, soil preparation: deep tillage, apply decomposed organic fertilizer 1500-2000kg per mu, and then level it to make the border. 2. Transplanting: autumn planting is generally carried out from the beginning of June to the middle and late June 10; Spring sowing is generally carried out from the middle and late April to the beginning of May every year, with a spacing of 30-40cm and a row spacing of 40cm.

1. What is the yield of Dictamni Dictamni per mu?

1, yield of Dictamni bark per mu

After 3-4 years of artificial cultivation and harvesting, the fresh dried roots of Dictyophora bungeana can be 300-350kg per mu (2.8-3.3kg fresh roots 1 kg fresh dried roots).

2. Harvesting technology

(1) Harvest time: in autumn, harvest after the overground part of the plant withers, or harvest before turning green in the following spring (autumn harvest is better).

(2) Harvesting method: after cutting off the stems and leaves on the ground, dig out all the roots of Dictamni, then remove the soil and residual stems attached to the roots and dry them in the sun. After air-drying to a semi-dry state, remove the fibrous roots, remove the hard core in the middle, that is, the xylem, air-dry to a completely dry state, and store in the warehouse.

Second, the planting method and time of Dictamni bark

1, soil preparation

(1) Choose a hillside with good drainage conditions and gentle slope for planting.

(2) After selecting the planting site, carry out deep ploughing, and at the same time, apply decomposed organic fertilizer 1500-2000kg per mu, and then level the ridge (100- 120cm wide and 20-30m long).

Step 2 transplant

(1) If it is planted in autumn, it is usually planted in the middle and late stages of 10 every year. If it is planted in spring, it is generally selected from the middle and late April to the beginning of May every year.

(2) Before transplanting, dig out the transplanting slot with a shovel, the width of the slot is 15-20cm, and the depth is adjusted according to seedling size. Then, put the terminal bud of the seedling upward into the transplanting slot to spread the root system of the seedling, with the terminal bud below the border 1-2cm and the plant spacing of 30-40cm. After solidification, cover with soil (the soil exceeds the terminal bud by about 3-5cm).

(3) Continue transplanting according to the above method, and the distance between two transplanting slots is about 40cm.

Step 3 manage

(1) Weeding should be done at least 2-3 times a year 1-2 years after transplanting.

(2) Topdressing in early May and late June, respectively, with 800- 1000 kg of decomposed farmyard manure or 8-1000 kg of urea per mu.

(3) After beginning of autumn, spraying 0.3-0.5% potassium dihydrogen phosphate solution on the leaves.

(4) During May-June, remove the buds and flowers of fresh white plants that are not ready to be planted, so as to promote the growth and development of plant roots and increase root weight.
