The management points for planting kudzu can refer to the following methods:
1. Timely vine training and vine fixing: kudzu has strong sprouting ability and fast vine growth, so promptly train and fix the vines after trellising. Select and keep 2-3 main vines per plant to climb the trellis, and prune away all the excess ones. For soil beds and ridges with many missing hills, 1-2 more kudzu vines may be kept for layering vines to fill the gaps. For the selected 2-3 main vines, remove all lateral branches within 1 m from the ground upward, and when the kudzu vines reach a trellis height of 2.5-3 m, promptly pinch off the growing tips to prevent excessive vegetative growth. For lateral branches more than 1 m above the main vine, pinch off the growing tips when they are 20-30 cm long.
2. Loosening soil and weeding: promptly carry out intertillage and soil loosening on the kudzu planting soil, remove weeds, and maintain good soil permeability, which is beneficial to the expansion of kudzu tuberous roots. 3. Applying tuber expansion fertilizer: July to October is the period of rapid tuber expansion for kudzu, requiring large amounts of water and nutrients, so apply fertilizer and irrigate promptly to promote tuber expansion. It is required to apply 1 liang of compound fertilizer per plant, with 40-60 kg of fertilizer per mu, applied in holes opened 5 cm away from the kudzu base, and irrigate promptly.
4. Layering vines to fill gaps: for soil beds and ridges with many missing hills, 1-2 main vines may be selected and not allowed to climb the trellis, and used for layering vines to fill gaps. First arrange the kudzu vines on the beds and ridges with missing hills, and press the internodes at the missing plant positions with soil clods. After new roots grow from the internodes, cut off the vines at both ends.
5. Preventing and controlling diseases, insects and rodents: in the middle and late stages of kudzu, pesticide use is generally not needed for disease and insect damage, but when disease and insect damage is severe on individual plants, pesticides with no residue and low toxicity may be selected for control, and combined with agricultural comprehensive measures such as intertillage weeding and pruning and vine training to remove diseased dead vines and fallen leaves. In the later stage, pay attention to preventing rats from gnawing and eating the kudzu roots.
