Detailed Explanation of the Latest Field Management Key Points for Kudzu Cultivation

Kudzu is a Chinese medicinal herb with a very long history in our country, and its scientific name is wild kudzu (Pueraria montana var. lobata). Kudzu is generally harvested in autumn and winter each year. Kudzu powder and kudzu soup made from kudzu have various effects such as raising yang and stopping diarrhea, and promoting fluid production and quenching thirst. Now 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 together!

1. Intertillage and weeding

Wild kudzu has relatively strong growth ability and strong growing capacity. Generally, before 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 drop in autumn, weeds should be removed once again. Because of its strong growth ability, weeding may not be necessary during the growing period. However, intertillage work should be done well, because intertillage 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 apply topdressing in time to meet the nutrients needed for wild kudzu growth. When applying topdressing, it can be combined with intertillage and weeding work. After wild kudzu enters the greening stage, apply decomposed farmyard manure once as topdressing. Then apply topdressing once again in winter 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 accumulated water, it will increase soil water content and prevent the roots from breathing. In mild cases, it reduces growth speed; in severe cases, it causes wild kudzu death.

3. Trellising and vine guiding

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 ropes to prevent them from being blown down by strong winds and to improve stability. Then pull several iron wires in the middle to make it easier for wild kudzu vines to climb. When the seedlings grow to about 30 cm, vine guiding 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, preventing premature leaf senescence. 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 growth period of wild kudzu, we should also control the growth of stems and vines well and do a good job in bud removal to prevent excessive nutrient consumption. Also, adjust the 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.
