The latest seed price and planting method of Polygala tenuifolia

Polygala tenuifolia is a perennial herb belonging to the family Polygalaceae, which grows in northeast, north, northwest, central China and Sichuan, and is born in grasslands, hillside grasslands, thickets and trees. Rhizome medicine has the effects of calming nerves and intelligence, expelling phlegm and reducing swelling. Let's take a look at the seed price and planting method of Polygala tenuifolia.

How much is Yuanzhi seed per jin?

The price of Polygala seed is about 90,120 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of the seed. Yuanzhixi cool climate, drought resistance, avoid high temperature, mostly wild in dry fields, roadsides, hillsides and other places, sunny, well-drained sandy cultivation is better, can also be cultivated on clay soil and calcareous loam, clay and low humidity areas are not suitable for planting, production reproduction methods are mainly seed propagation, direct seeding or seedling transplanting can be used.

Sowing method of Polygala tenuifolia

1. Sowing time: Yuanzhi spring sowing is in the middle and late April, and autumn sowing is in the middle and late August, taking measures according to local conditions, not too late, so as to ensure that the seedlings will not die because the temperature is too low. Generally, the whole ground is watered first, and the seeds are sown after underwater infiltration.

2. Sowing method: Polygala tenuifolia seeds 1: 1.5 kg per mu, soak the seeds with water or 0.3% potassium dihydrogen phosphate solution for 1 day and night before sowing, fish out and mix with 3-fold fine sand, sow seeds in late August for autumn sowing, and emerge in the spring of the following year.

3. Seedling transplanting: Polygala tenuifolia seedlings were transplanted in the early and middle of March, sowed on the seedling bed, covered with soil about 1 cm, kept the seedling bed moist, and the temperature was controlled at 15-20 ℃. The seedlings emerged about 10 days after sowing, and the seedlings were planted when the seedling height was 5 cm.

The planting method of Polygala paniculata

The main results are as follows: 1. Land selection and land preparation: it is better for Yuanzhi to cultivate sandy soil with sunny direction and good drainage. When ploughing the land, it is better to apply sufficient bottom fertilizer at one time, circle manure or compost 40000 kg / ha, and calcium superphosphate 750kg.

2. Replenishing seedlings: when the height of Polygala tenuifolia seedlings is 3cm to 5cm, the seedlings should be carried out according to the plant spacing of 3cm and 6cm, and the seedlings should be replenished in time where the seedlings are missing. The best transplanting should be in rainy days or in the afternoon.

4. Watering and fertilization: except for proper watering during seed germination and seedling stage, there is generally no need for regular watering in the later stage of growth. Once a year in winter and spring and from April to May, 20-25 kg of cake fertilizer or 20 kg of superphosphate can be applied per mu.

5. Extra-root topdressing: from mid-June to mid-July, Yuanzhi sprays 1% potassium sulfate 50 kg 60 kg per mu or 0.3% potassium dihydrogen phosphate 80 kg 100 kg per mu, once every 10 days, even 2 times 3 times, preferably after 5 o'clock in the afternoon.

6. Disease and pest control

① root rot: the diseased plants were removed and burned in time, and 50% carbendazim 1000 times solution was sprayed 2 times 3 times every 6-7 days at the initial stage of the disease.

② aphids: spray with 40% omethoate 1500 times solution, once every 6-7 days, twice in a row.

③ leaf blight: it can be sprayed 1 times twice with mancozeb 800 × 1000 times solution or redoxomycin 800 times solution.
