The Latest High-Yield Cultivation Techniques and Methods Tutorial for Kudzu
Kudzu, also known as fen ge, is a climbing vine in the Fabaceae (legume) family, genus Pueraria, with extremely high food value, economic value and healthcare value. Its cultivation returns are very high, and its development and utilisation is currently a hot topic both in China and abroad. How can high yields be achieved when growing it? Come and take a look with the editor.
1. Site selection and land preparation
To achieve high yields, the first requirement is loose, fertile soil with a deep soil layer and good drainage - humus soil or sandy loam with a pH between 6 and 8. The growing site must also be close to a water source, have plenty of sunlight, and be far from industrial pollution zones. After choosing the growing site, prepare the land early, plough the soil and let it weather to increase soil fertility, then dig planting trenches according to the terrain, with each trench 50-60 cm deep and 50-60 cm wide. During land preparation, remove weeds and crop residues from the plot, kill insect pests, and reduce pest damage. Because kudzu has a long growth cycle and must be grown for 2-3 years before harvest, apply plenty of base fertiliser: generally 4000-5000 [units] of rotted organic fertiliser per mu, 15-20 kg of NPK compound fertiliser, and 10-20 kg of phosphate fertiliser. Apply these into the planting trenches, then backfill 20-30 cm of topsoil and mix the fertiliser and soil evenly.
2. Selecting good varieties
When planting, you must select good varieties according to local soil, climate and intended use, so as to increase yields and meet processing goals. For example, if the roots are to be used to make kudzu starch, choose varieties with a high starch content; if they are to be used medicinally as a raw material for drugs, choose varieties with a higher flavonoid content. Choosing different varieties for different uses is the way to maximise the benefits.
3. Field management
Kudzu is a plant that tolerates heavy fertilisation and needs multiple applications of fertiliser throughout the growing period. The first is when the seedlings grow to 25-30 cm, when 3-5 kg of manure water is poured around each plant; afterwards, topdress once every 30-45 days, depending on the actual condition of the plants. Kudzu has extremely strong sprouting ability, so when the seedlings grow to 15-20 cm, thin them in time, leaving 1-2 strong seedlings per hole. When applying the first fertiliser, also set up trellises and train the vines to improve air movement between plants. When the seedlings grow to 2 m, pinch out the growing tips in time to encourage more branching and enhance photosynthesis. When there are too many leaves, this affects photosynthesis and also consumes a large amount of nutrients, so at this point remove leaves in time; this favours the growth and swelling of the storage roots and increases yields.
4. Pests and diseases
Pests and diseases are also one of the factors harming kudzu yields. Common diseases include powdery mildew and root rot, while insect pests include stem borers, locusts and aphids. Pest and disease control should be based on prevention, with integrated management: use methods such as crop rotation, soil sterilisation, inter-row cultivation and weeding, pruning and vine training, and increased fertiliser application to promote strong kudzu growth, increase its disease resistance and stress tolerance, and reduce pests and diseases. Pest and disease control must be timely - once pests or diseases are found, spray pesticide promptly for control.
