Detailed Explanation of Field Management Techniques for Kudzu
Kudzu is a traditional Chinese medicinal herb with a very long history in China, and its scientific name is wild kudzu (Pueraria lobata). Kudzu is generally harvested in autumn and winter each year, and kudzu powder, kudzu soup, and other products made from kudzu all have various effects such as raising yang and stopping diarrhea, and promoting fluid production to quench thirst. Nowadays, kudzu also has a certain planting area. So how should we manage kudzu when planting it? Below, the editor brings you the key points of field management for kudzu. Let's take a look!
1. Cultivation and Weeding
Wild kudzu has relatively strong growth ability and strong growing capacity. Generally, before the wild kudzu seeds germinate in spring, weeds should be removed once to prevent too many weeds from competing for nutrients, affecting seed germination and reducing the emergence rate. Then after leaf fall in autumn, weeds should be removed again. Because of its strong growth ability, weeding may not be necessary during the growing period. However, cultivation work should be done well, because cultivation can effectively loosen the soil and improve soil quality. It promotes the growth of wild kudzu roots, further improves the growth ability of wild kudzu, and increases yield.
2. Water and Fertilizer Management
As just mentioned, wild kudzu has strong growth ability, so when planting, we should topdress in time to meet the nutrients needed for wild kudzu growth. When topdressing, it can be combined with cultivation and weeding work. After wild kudzu enters the green-returning stage, apply decomposed farmyard manure once. Then in winter, apply fertilizer once again to help wild kudzu overwinter. Although water is also very important for wild kudzu growth, while maintaining soil moisture, attention should be paid to water quantity. Water should not be too much. If there is too much standing water, it will increase soil water content and prevent the roots from breathing. In mild cases, it reduces growth speed; in severe cases, it can cause wild kudzu death.
3. Trellising and Vine Training
Wild kudzu is a trailing vine plant, so when planting, in order to ensure the growth of wild kudzu, supports should be set up in time. The height of the supports should be kept at about 2 m, and then supports should be set up between two rows with good spacing control. Then fix two adjacent supports with rope to prevent them from being blown down by strong winds and improve stability. Then pull a few iron wires in the middle to make it easier for wild kudzu vines to climb. When the seedlings grow to about 30 cm, vine training work should be carried out in time. This can improve field ventilation and light penetration and promote the growth of wild kudzu.
4. Spraying Foliar Fertilizer
Reasonably spraying foliar fertilizer is very helpful for the growth of wild kudzu. Foliar fertilizer is rich in nutrient elements and can supplement the various nutrients needed by wild kudzu. It improves the growth of wild kudzu and can also effectively adjust and control the growth and development of wild kudzu to prevent premature leaf aging. When spraying foliar fertilizer, it is best to carry it out together with pest and disease control work. Because after entering summer, temperature and humidity will gradually increase. Under such conditions, the incidence of pests and diseases will increase greatly, so we can carry them out together. While supplementing nutrients, pest and disease control work can also be done well.
During the growing period of wild kudzu, we should also control the growth of stems and vines well, do a good job in bud removal, and prevent excessive nutrient consumption. Also adjust plant and row spacing well, improve ventilation and light penetration, increase light duration, and strengthen shaping and pruning. That is all for today's introduction.
