The effect and role of Pueraria? Pueraria lobata, also known as pueraria, gems, etc., is a leguminous plant of the genus Aralia. It is rich in starch and isoflavones, and has more than ten kinds of human body such as calcium, selenium, iron, copper, phosphorus and potassium. Trace elements, have the effect of no hunger, no antipyretic, antipyretic, thirst, appetizing, anti-cancer, etc. Let's take a look at Pueraria planting technology!
What are the Pueraria planting techniques? Gegen planting prospects Ge is a rare and pollution-free green food, the whole body is treasure, Pueraria can make precious starch, Gehua is a good hangover medicine, Ge Ye is a high-quality feed, and Geji is a high-grade fiber raw material. At present, Gegen is very popular in Europe, America and Southeast Asia, and the price is firm. The price of Pueraria starch is as high as 50 yuan per kilogram, and the extract of pueraria flavonoids is 20,000 to 30,000 yuan per kilogram. Ge is suitable for planting in rural areas. The market demand is large, and the prospect of artificial planting is promising.
Gegen roots are selected for planting Pueraria lobata in order to obtain better economic benefits. Therefore, when selecting good varieties, high-yield Pueraria lobata seedlings should be selected, such as high-yield fast-growing Pueraria 119, Musheng Pueraria, Yuge 3, Song's pueraria, etc. Provincial species of wild geese and crude fiber, otherwise it will cause low benefits.
Pueraria seedling technology
1. Preparation of seedbed: Choose a mountain or garden where leeward sun, sandy soil, and no livestock are harmful. The bed of the seedling bed is 15-20 cm high and the ridge width is 60-100 cm. The length is not limited. Each square meter of fermented manure or soil fertilizer is 1.5 to 2.5 kg. Deeply flattened, the middle of the seedbed is slightly raised, and the grooves on both sides are 20 to 30 cm wide.
2. Seeding operation: Before seeding, the seedbed should be fully moistened. The fine cultivar of the genus Gypsophila should be selected as a species with a shoot bud. The buds are cut into 6~10 cm segments and scattered in the whole. In order to avoid overlap, cover 2~3 mm thick fine soil on the top, in principle, reach the looming, then apply some decomposed manure, then cover a layer of straw, use 2 meters of bamboo or small bamboo strips, in the seedbed Insert it into an arch, insert one every 35 cm. Cover the agricultural film, the seedbed is completely covered with arches, and the surrounding is compacted with soil.
3, seedbed management: due to the lower temperature during the nursery period, the water consumption of the seed strips is not large, about 10 days if the ridge surface is dry, it can be watered once. After planting the roots, the water needs to be increased appropriately, and water is poured every 3 days to keep the seedbed fully moist. The temperature of the seedbed is preferably around 20 °C.
When the temperature reaches 30 °C or above, the film should be ventilated or sprayed to adjust the temperature so that the covered straw should be uncovered when the seed is germinated, avoiding direct sunlight, and the sun is properly shaded at noon to prevent burns. The ear grows twigs, and the leaves are 3 pieces. When the length is 5 cm, the seedlings can be taken with the soil, and the seedling movement should be light to avoid injury.
Pueraria Plantation Management
1. Site selection: artificial cultivation of Pueraria, to obtain high yield, we must first choose a good land. First, the sweet potato and soybean land can be replanted. The second is to choose a sandy soil with thick soil and good drainage. The ridge of the whole land began in mid-February. Before the land preparation, 500 kg of fertilizer was applied per mu, 500 kg of stove ash, 50 kg of calcium, magnesium and phosphate fertilizer or 200 kg of compound fertilizer. In the preparation of the land, like the sweet potato ridge, the ridge height is 60-70 cm, and the ridge length is determined by the convenient operation of the land.
2, reasonable close planting: from the end of February to mid-March, choose cloudy weather without the windy weather transplanting, the seedling bed before the transplant should be watered, in order to bring soil seedlings. Planting 500-700 plants per acre, the plant spacing is about one meter. Before planting the seedlings, first discharge the seedlings on the ridge according to the plant spacing, then dig a small hole, put the seedlings into the human hole, cover 2 cm of fine soil, and compact the soil with both hands. Yes.
3. Replenishing seedlings and fertilizing: After transplanting the seedlings, the roots of the human and animal dung water can be properly diluted, and the inspection should be carried out, and the dead seedlings should be replanted in time. When the seedling grows to about 30 cm, it must be tempered twice, sprayed with 0.3 to 0.5% of urea water, sprayed once every 15 days, and then properly topdressed.
4, cultivating and weeding: After the vine grows to 1 to 2 meters, it is necessary to cultivate and weed. Although Pueraria is highly resistant, it will inevitably lead to some pests and diseases, especially in the key season of tuber growth from June to August. In order to keep the leaves strong, if necessary, carry out no-drug control or use lime powder to prevent and control.
5, harvested and retained: Gegen can be mined in the same year, but also in the second year. Generally, the starch content is the highest in the period from November to December. When mining, you can dig large and stay small, so that you can invest once and benefit in the long run. Pueraria is mainly vegetatively propagated, and the planting can also choose the thick and pure plant cane as the second year of planting, and it can be used for planting from 1.5 meters above the crotch.
