Artificial planting of Pueraria lobata

Artificial planting of Pueraria lobata is suitable for planting in low-lying land such as wasteland, farmland, vegetable garden in front of house and vegetable garden behind house. ㈠ selected improved varieties. Take stereotyped and high-yielding Pueraria lobata as the main, supplemented by local folk cultivation species, and never try to save trouble and plant local varieties of Pueraria lobata and crude fiber. ㈡ plastic film seedling 1. Preparation of nutritious nursery bed: it is better to choose sandy loam in mountain or garden where there is no harm to livestock and poultry. The seedling bed is 15-20 cm high, 60-100 cm wide and unlimited in length. Apply 15-25 kg of rotten stable manure or soil fertilizer 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. 2, seeding operation: ① seeding before the seedbed should be fully moist; ② will select a good variety of kudzu vine, with a branch bud as a seed, cut the bud nodes to grow 6-10 cm segments, scattered on the whole seedbed to avoid overlap, covered with 2-3 mm thick fine soil, exposed. Then sprinkle some rotten barnyard manure and cover it with a layer of straw. ③ uses about 2 meters of bamboo or small bamboo strips to arch the seedbed, one every 35 centimeters. Cover the agricultural film, cover the nursery bed into an arch, and compact it with soil around. 3. Nursery bed management: if the ridge surface is dry in about 10 days, it can be watered once. When the roots sprouted, they were watered every 3 days or so, and the temperature of the seedling bed was about 20 ℃. When the temperature is above 30 ℃, the film ventilation or water spray regulation should be opened. When the seed ear sprouts, the covered straw is opened, the sunny day is properly shaded at noon, the seed ear produces twigs, 3 leaves are unfolded, and the seedling can be raised with soil when the length is 5 cm. ㈢ selects and prepares land. First, sweet potato land can be used to replant; second, sandy soil with thick soil layer and good drainage can be selected for planting. Soil preparation began in mid-February. 500 kg of barnyard manure, 500 kg of kitchen ash, 50 kg of calcium magnesium phosphate fertilizer or 200 kg of compound fertilizer were applied per mu before soil preparation. The width of the ridge of soil preparation is 60-70 cm and the length of the ridge is easy to operate. ㈣ reasonable close planting. From the end of the month to the middle of March, choose sunny days when there is no strong wind in cloudy days, and the seedbed should be watered thoroughly before transplanting. Plant 1200-1400 plants per mu with a spacing of 30 cm, depending on the topography. Remember, be sure to plant at an angle of 30 degrees. This method grows fast and is easy to dig and save labor. Before planting the seedlings, first put the seedlings on the ridge according to the distance between the plants, then dig a small hole, put the seedlings into the holes, cover 2 cm of fine soil, and compact the soil with both hands. ㈤ strengthens its management. When the seedling grows to 10-20 cm high, it should be inserted into the rack. Insert frame material with about 2 meters long bamboo or firewood, obliquely inserted and crossed into rows. After seedling transplantation, diluted human and animal dung water can be used as root water. When the seedling grows to about 30 cm, the seedlings must be urged twice, and the urea water of 0.3% Mo 0.5% can be sprayed every 15 days, and the fertilizer can be applied properly later. Kudzu vine should be ploughed and weeded when it grows to 1-2 meters. From June to August, non-residual drugs or lime powder were used to prevent the disease. ㈥ pruning. When the kudzu vine grows to about 1.5 meters, the topsoil is planed. When you see the root tip, choose 1-2 sturdy root blocks to leave, the rest of the root system is cut off with a blade, and then cover the topsoil. Leave 1-2 sturdy vines per tree as the main vine, and cut off all the others. In the range of 1-1.5 meters from the root of the main vine, the lateral bud vine should also be cut off to prevent the growth of twigs. When the main vine grows to 5 meters long, cut off the top. ㈦ harvesting and seed keeping. Gegen can be excavated in the same year, or in the second year, and the starch content is the highest from November to December. Pueraria lobata is mainly asexual reproduction. The section chooses sturdy and pure plant vines as seed strips for the second year, which can be used as seed strips from 1.5 meters above the stem.
