Panax notoginseng, the name of traditional Chinese medicine. Mainly produced in Wenshan Prefecture, Yunnan Province, hence the name Wenshan Panax notoginseng, also known as Wenzhou Sanqi. So how much is the seed of Panax notoginseng in 2018? How much is one mu of land? When will you plant it? How to raise seedlings and plant them? According to Master Wang, a big grower of Panax notoginseng in Wenshan, the starting price of 1-9 kg of Panax notoginseng seeds is 350-370 yuan / jin, 10-99 kg is 320-340 yuan / jin, and the starting price of more than 1 kg is 260 yuan / jin. And now you can buy seeds directly online, but be careful to buy fake or shoddy seeds.

How much is the seed of Panax notoginseng per mu?

The seeds of Panax notoginseng are post-mature and need to be preserved in wet sand from December to January of the following year before they can be released from dormancy, and then they can be sown. Sowing according to the specification of 4x5cm self-made template, 2-3cm deep soil holes were made on the border surface for on-demand sowing, and the sowing rate was 180000-200000 seeds per mu. The transplanting of seedlings is required from December to January of the following year, and the method also uses the template of 1012.5cm or 1015cm to dig holes.

When will Panax notoginseng be planted?

1. Panax notoginseng is planted every year from October to November.

2. Panax notoginseng enjoys a warm winter and cool summer environment, which is not resistant to severe cold and avoid strong light. Humic loam with cool and ventilated, loose, fertile and well drained soil should be selected for cultivation.

How to raise seedlings and plant Panax notoginseng?

The main results are as follows: 1. Medium-acid sandy loam should be selected for land selection and soil preparation, the plot with certain slope is convenient for drainage and irrigation, the soil pH value is 5.5m-7.0m, and the altitude requirement is 1000-1800m. In order to ensure the production of high quality Panax notoginseng, it is necessary to consider whether the content of agricultural residues and heavy metals in the soil exceeds the standard. The limit standard is as follows: BHC ≤ 0.2mg ≤ 0.2mg lmg/kg,As ≤ 0.2mg lead ≤ 50mg lmg/kg,As 20mg/kg Cu ≤ 80mg ≤ 20mg/kg CD ≤ 2mg lmg/kg,As 20mg/kg. Panax notoginseng soil preparation requires three ploughs and three harrows, fully broken soil, and sun exposure, there have been planted Panax notoginseng plots, need to use 50-70kg lime per mu of land for disinfection.

2. The construction of the shed and the planting bed shall be planted according to 1.8 × 1.8m, and the construction materials can be made of Panax notoginseng special shading net or local materials, using branches, mountain grasses and crop straw, but the light transmittance should be adjusted to between 8% and 15%, not more than 20%, and absolutely not more than 30%, otherwise Panax notoginseng can not grow normally. The height of the shade canopy is about 1.8-2m, too low is not conducive to agricultural operation, too high is easy to be affected by wind disaster. The border of Panax notoginseng is required to be 120-140cm wide and 15-20cm high, and made into a tile type, so that the soil is solid and empty.

3. The seeds of Panax notoginseng are post-mature and need to be preserved in wet sand from December to January of the following year before they can be released from dormancy, and then the seeds can be sown. Sowing according to the specification of 4x5cm self-made template, 2-3cm deep soil holes were made on the border surface for on-demand sowing, and the sowing rate was 180000-200000 seeds per mu. The transplanting of seedlings is required from December to January of the following year. The method also uses the template of 10 × l2.5cm or 10 × l5cm to make the dormant buds transplant downward, and the planting density is 26000-32000 plants / mu. Before sowing and transplanting, the seeds should be soaked with 64% poisonous alum + 50% carbendazim 500 times solution. After planting, the seeds should be covered with fiery soil or fine soil and mixed with farm manure until the sowing material is not visible, followed by a layer of crushed mountain grass or pine hair.

4. Field management:

a. Drought-resistant watering. After sowing, Panax notoginseng does not emerge until March to April, during which artificial watering is needed (if the soil has night tide, it can not be irrigated). The method needs to be irrigated to the border surface with sprinklers, generally 2-3 times a month until the rainy season comes.

b. Adjust the transmission of light. The light transmittance requirement of one-and two-year-old Panax notoginseng is low, which is generally about 10%, while that of three-year-old Panax notoginseng requires a strong light transmittance, which is about 15%. By adjusting the light transmittance in the shade shed, the root weight of a single plant can be increased.

c. Top dressing. Panax notoginseng bud stage (June) and flowering stage (September) is the peak of fertilizer absorption, at this time should be topdressing Panax notoginseng. The topdressing of Panax notoginseng is mainly farm manure, supplemented by a small amount of compound fertilizer, the amount of topdressing of farm manure is 2000-2500kg/ mu / time, and that of compound fertilizer (15-15-15) is 10-15kg/ mu? Once.

d. Picking buds, thinning flowers and protecting fruits. When the flower base of Panax notoginseng is 3-5cm, the root yield can be greatly increased in the cool area where the main goal is to produce root tuber. The satisfactory yield of red seeds (fruits) of Panax notoginseng can be obtained by thinning out the inflorescence of the central bud in the reserved field at the flowering stage of Panax notoginseng.

e. The seven gardens are clean. Remove all kinds of weeds in Panax notoginseng garden in time, remove the remains of diseased plants, and stay away from burning or deep burial in the seven gardens. The cleaning of Qiyuan is an important measure to improve the light transmission of Panax notoginseng and prevent the spread of diseases, which must be paid great attention to. (5) Disease and pest control of Panax notoginseng due to its long cultivation years (2-3 years) and growing in shade and high humidity, the diseases of Panax notoginseng are more and spread rapidly, and the main diseases are black spot and root rot. The insect pests of Panax notoginseng generally do not pose a harm, and phoxim can be used for 1-2 times in the whole growth period.
