Price and planting method of Pueraria lobata seedlings

Pueraria lobata, etc., are the dry roots of Pueraria lobata, which are distributed in other areas of our country except * * and Xizang. It is used in medicine to clear away heat and detoxification, relieve spasm and analgesia, and has the effect of ascending yang and relieving muscle, penetrating rash and relieving diarrhea. The cultivation value is very high. Let's take a look at the seedling price and planting method of Pueraria lobata.

How much is a kudzu seedling?

The price of kudzu seedling is about 0.4-1.2 yuan per plant, but it varies according to the quality, specification, producing area and market of the seedling. Pueraria lobata has strong adaptability, likes warm and humid environment, has certain cold and drought tolerance, and is not very strict on soil, but it is better to use loam or sandy loam with loose and fertile soil and good drainage. Seed propagation and cuttage propagation are mainly used in production. Root propagation and striping propagation are also used.

Propagation methods of Pueraria lobata

1. Seed propagation: soak the seeds in 40 ℃ warm water for 1-2 days before and after the Qingming Festival and often stir them. After taking out the drying water, the seeds are planted in the middle of the finished border. The hole is 3 cm deep, the plant spacing is 35-40 cm, each hole is 4-6, and the seedlings are watered in flat holes. About 10 days later.

2. Cuttage propagation: when picking kudzu root in autumn, leave the strong rattan stem to cut off the head and tail, select the middle part to cut into 25cm and 30cm cuttings, each with 3cm cuttings, put them in a cool place mixed with wet sand pseudo-planting, and cut holes in the border before and after the Qingming Festival in the second year.

Planting method of Pueraria lobata

1. Land selection and land preparation: Pueraria is not very strict on soil. Before winter, 2000-3000 kg of farm manure per mu was applied, and the following spring, the soil was turned shallowly, broken, raked fine and leveled, and made into a border with a width of 1 to 1.2 meters, with a ditch of about 30 centimeters between the borders.

2. Weeding in middle ploughing: kudzu root grows fast, and weeding is needed when it grows to 1 to 2 meters. Usually, secondary weeds are removed before germination in early spring and after defoliation in late autumn, and weeding is generally not needed in the growing period.

3. Reasonable topdressing: Pueraria topdressing can be combined with intermediate ploughing and weeding, returning green fertilizer is mainly rotten manure, 1000 kg per mu, urea can be properly applied, overwintering fertilizer is mainly farm manure, and a small amount of potash fertilizer can be applied in combination with watering every year.

4. Framing and drawing vine: kudzu root cultivation must set up a wooden column every 2 to 3 meters between the two rows, and the columns are connected with iron wire. Bamboo poles or iron wires are tied between the border and border to facilitate climbing. When the seedling is 30 cm high, it can lead to the vine on the shelf.

5. Picking buds and pruning: during the growing period of Pueraria lobata, stem and rattan growth should be controlled, terminal buds should be removed to reduce nutrient consumption, plant shape should be adjusted reasonably to make full use of sunlight, and withered vines and diseased branches should be cut off in time.

6. pest control: during the growing period of Pueraria lobata, there are mainly crickets, beetles and other pests. Crickets can be sprayed with 2000 times of dichlorvos EC, and beetles spray leaves with 1000 times of 90% crystal trichlorfon from May to June. Dimethoate and insecticidal mites can be used to control other pests.

7. Timely mining: kudzu root can be cultivated in late autumn and early winter or early spring for 2 ~ 3 years. Dig out all the roots, remove the stem vine and fibrous root, scrape off the rough skin, cut into small segments of 10 cm, cut longitudinally into pieces about 5 cm thick, and dry with the Kang or soaked in 2% lime water.
