How to manage kudzu root (Pueraria montana) for high yields
How to manage kudzu root planting for high yields? Here is an introduction. The following methods can be used for managing kudzu root planting: 1. Thinning and replanting seedlings. After the directly sown seedlings emerge completely, thin and replant them, keeping 1-2 strong seedlings per hole, and fill in the gaps where seedlings are missing.

How to manage kudzu root planting for high yields? Here is an introduction.
The following methods can be used for managing kudzu root planting:
1. Thinning and replanting seedlings. After the directly sown seedlings emerge completely, thin and replant them, keeping 1-2 strong seedlings per hole, and fill in the gaps where seedlings are missing. After transplanting the seedlings, they can be appropriately watered with diluted human and livestock manure water to settle the roots. During the seedling stage, weed frequently, and apply 0.3%-0.5% urea water as a top dressing 2-3 times. From the second year onward, management is the same as for other transplanted seedlings.
2. Intertillage weeding and fertilizing. After planting kudzu, intertill and weed 3 times in the first year: the first time after the seedlings emerge completely, the second time in June-July, and the third time after leaf fall in winter. From the second year onward, intertill twice each year: the first time after the seedlings emerge completely in spring, and the second time after the leaves wither in winter. Intertillage requires removing weeds and shallowly hoeing the soil around the holes. After each intertillage and weeding, apply a top dressing. In the first year, apply 600-800 kg of human and livestock manure water per 667 sq m each time. In subsequent years, when applying top dressings, apply less nitrogen fertilizer and more phosphorus and potassium fertilizers such as superphosphate and wood ash to promote root growth.
3. Removing terminal buds and flower clusters. In the summer of the 1st-2nd years after planting, when the vines grow to about 2 m, remove the terminal buds to encourage branching and increase leaf area. From May to July each year, except for those intentionally left for flowers and seeds, remove flower clusters promptly to reduce nutrient consumption.
4. Pest control
1. Crickets. They bite and eat young seedlings. Control method: spray with 80% dichlorvos emulsifiable concentrate at 2000 times dilution.
2. Scarab beetles. Adults come out at night in May-June to bite and eat leaves. Control methods: use light traps to kill them, or spray the leaf surface with 90% trichlorfon crystal at 1000 times dilution for control. You can also shake the kudzu vines and catch and kill them when they feign death and fall to the ground.
3. Blister beetles. When kudzu flowers open, they bite and eat the petals. Control method: in the morning while the dew is not yet dry and they are unable to fly, catch them and suffocate them in white liquor, then dry them in the sun for medicinal use.
