How to raise seedlings of Pueraria lobata? How to grow kudzu root?

Kudzu root is covered with treasures, stem bark fiber can twist rope, weave kudzu cloth, can also be used as raw materials for papermaking. At the same time, the leaves of Pueraria lobata are still excellent green fodder, which can be fed to pigs and rabbits, which has high planting value. In the process of planting Pueraria lobata, it is the foundation to do a good job of raising seedlings. So, how to raise seedlings of Pueraria lobata? The following is to introduce the seedling techniques of Pueraria lobata. Let's take a look.

First, seedbed preparation

Choose leeward to the sun, sandy soil, no livestock and poultry harm of the mountain or garden as a seedbed. The seedling bed is 15-20 cm high, 60-100 cm wide and unlimited in length. Apply 1.5-2.5 kg of rotten stable manure or soil manure per square meter. Turn deeply and rake flat, the seedbed is slightly raised in the middle, and the width of the ditch on both sides is 20-30 cm.

II. Seeding operation

Before planting, the nursery bed should be fully moist. Take the selected fine varieties of kudzu vine, take one branch bud as a seed, cut the bud nodes to grow 6-10 cm segments, and scatter them on the whole seedbed. In order to avoid overlap, cover them with fine soil 2-3 mm thick, which is looming in principle, and then sprinkle some mature stable fertilizer, cover a layer of straw, and use about 2 meters of bamboo or small bamboo strips to insert into an arch on the seedbed. Insert one every 35 centimeters. Cover the agricultural film, fully cover the nursery bed into an arch, and compact it with soil around.

III. Seedbed management

Due to the low temperature during the seedling period, the water consumption of the seed strip is small, so it can be watered once if the ridge surface is dry in about 10 days. When the roots sprout, the moisture needs to be increased appropriately and watered every 3 days or so to keep the seedbed fully moist. The suitable temperature of seedling bed is about 20 ℃. When the temperature is more than 30 ℃, the film should be ventilated or water sprayed to balance the temperature. When the seed ear sprouts, the covered straw should be opened to avoid direct sunlight and shade properly at noon on a sunny day to prevent burns. Seed ear growth twigs, spread leaves 3, length 5 cm can be carried out with soil seedling, seedling action should be light, so as to avoid injury.

[conclusion] to do a good job in raising seedlings of Pueraria lobata is the basis for the successful planting of Pueraria lobata, which should be paid attention to. The above introduces the seedling technology of Pueraria lobata. I hope it can be helpful to you!

How to grow kudzu root?

Pueraria lobata, also known as Pueraria lobata, Pueraria lobata, Pueraria lobata and so on, is the dried root of Pueraria lobata. Pueraria lobata is a very common traditional Chinese medicine, which has the effects of relieving muscle fever, invigorating body and relieving thirst, relieving yang and relieving diarrhea. It is a new green health care longevity food and export products with high planting value. So, when will kudzu root be planted? How do you plant it? The planting time and method of Pueraria lobata are introduced as follows.

1. Planting time of Pueraria lobata

The best planting period of Pueraria lobata is from mid-late March to early April (the temperature at noon should not be lower than 10 ℃). The seedlings (with root) or truncated seedlings (with 2 stem nodes, without roots) were planted into the soil at an angle of 30 degrees from the ground. Note that the growing point at the stem node of the seedling must be exposed to the soil surface; the two stem nodes of the seedling must be one in the soil and the other outside the soil.

II. Planting methods of Pueraria lobata

1. Land selection and land preparation: kudzu planting chooses plots with good drainage, which are turned 30 cm deep before winter, 2000-3000 kg of farm manure per mu combined with ploughing, and turn evenly into the soil. The following spring, you can turn the soil shallowly again, smash the soil, rake fine rakes evenly, level it, and make a border with a width of 1-1.2m, with a ditch of about 30cm between the borders.

two。 Seed propagation: soak the seeds in 40 ℃ warm water for 1-2 days before and after the Qingming Festival in spring, and often stir them. After taking out the dry water, sow seeds in the middle of the finished border. The hole depth is 3 cm, the plant spacing is 35-40 cm, and each hole sows 4-6 seeds. After sowing, the seeds are watered, and the seedlings emerge in about 10 days.

3. Intermediate ploughing weeding: kudzu grows faster, weeding secondary weeds before sprouting in early spring, and then weeding after defoliation in late autumn, there is generally no need to weed frequently in the growing period.

4. Reasonable topdressing: it can be combined with ploughing and weeding. After turning green, returning green fertilizer is mainly manure of rotten acquaintances, 1000 kg per mu, urea can be properly applied, and overwintering fertilizer is applied after defoliation, mainly farm manure. The annual peak growth period can be combined with watering, and the application of a small amount of potassium fertilizer can promote root growth.

5. Timely scaffolding: wild kudzu cultivation must be set up. A wooden column can be erected every 2-3 meters between the two rows. The columns are connected with iron wire. Bamboo poles or iron wires are tied to the border to facilitate climbing. When the seedling is 30 cm high, it can lead to the vine on the shelf.

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

7. Prevention and control of diseases: there are not many diseases of Pueraria lobata, and there are mainly pests such as crickets and beetles in the growing period. Crickets can be sprayed with 2000 times of 80% 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.

8. Harvest and processing: cultivated Pueraria lobata can be harvested at the end of autumn and early winter or before early spring. When digging, dig out all the roots, remove the stem vines and fibrous roots, scrape off the rough skin, cut into small sections of about 10cm, cut longitudinally into strips about 5cm thick, and dry with the Kang or soaked in 2% lime water. It is better to have a white color and more powder without mildew.

[editor's conclusion] Gegen likes the warm supermarket environment, has a certain ability of cold and drought tolerance, and grows well in loose, fertile loam or sandy loam. Special attention should be paid to planting. The above introduces the planting time and method of Pueraria lobata. I hope it can help you!
