What are the key points of kudzu root cultivation techniques? This article will help you master them
Kudzu root is often consumed in our daily lives, especially in the form of kudzu root powder. It has the effects of relieving fever, promoting eruption, promoting fluid production and quenching thirst, and elevating yang to stop diarrhea. It can be used to treat symptoms such as fever, febrile diseases, yin deficiency, and spleen deficiency. So how should kudzu root be cultivated? Today, the editor will take you through the key technical points of kudzu root cultivation.
1. Variety selection
Cultivating kudzu root is mainly for obtaining higher economic benefits, so it is necessary to improve the yield and quality of kudzu root. Therefore, the selection of kudzu root varieties is the most basic condition. Before planting, we need to investigate the local kudzu root market and select high-quality kudzu root seedlings based on local climate, soil, and other conditions. Varieties such as Musheng kudzu root and Gan Ge No. 3 are currently very good choices.
2. Fine land preparation
Another very important basic condition for kudzu root cultivation is the selection and improvement of soil. The most suitable soil for planting kudzu root needs to have the characteristics of fertility, sufficient water source, loose texture, good drainage, and rich organic matter content. Land preparation should be carried out at least about one month before planting. The soil needs to be weathered to improve soil fertility, and then sufficient base fertilizer should be applied, such as farmyard manure, ternary compound fertilizer, phosphate fertilizer, etc. Finally, trenches should be opened, with a depth of about 55 cm and a width of about 50 cm.
3. Seedling raising techniques
Before raising seedlings, a seedbed needs to be prepared. The seedbed is mainly based on decomposed stable manure, then covered with a layer of rice straw. Bamboo strips are used to build an arch in the seedbed, and a layer of agricultural plastic film is covered on top. The surroundings need to be covered with soil to ensure firmness. After the seedbed is ready, seedlings are cultivated by vine cutting or bud node cutting. The most commonly used method is bud node cutting. The length of the bud node is about 10 cm, and then it is treated with medication to increase the seedling emergence rate of the bud nodes.
4. Seedling transplanting
The main things to pay attention to in seedling transplanting are soil disinfection and management of planting density. Before planting, we need to thoroughly disinfect the soil once, and then spread some pesticides to prevent underground pests such as ants and cutworms. Generally, about 600 to 700 plants can be planted per mu, so the distance between rows is about 1 m, and the distance between plants is about 60 to 70 cm. Finally, fill in the soil and compact it, and water the soil thoroughly.
5. Planting management
Later topdressing of kudzu root needs to be carried out according to the growth of the seedlings. Kudzu root is a fertilizer-loving plant, and its usable part is its root. Therefore, in the early stage, we need to apply nitrogen fertilizer to promote seedling growth. In the middle and later stages, reduce the use of nitrogen fertilizer to avoid excessive vine growth in kudzu root seedlings. In the later stage, in order to promote root enlargement, we mainly need to apply potassium fertilizer and phosphate fertilizer, and reasonably spray foliar fertilizer to prevent branches and leaves from aging. Secondly, we also need to pay attention to whether we need to build supports when the seedlings grow to about 50 cm, guiding the vines to climb and grow. This can reasonably utilize land resources and also increase the yield of kudzu root. Finally, during the growth of the vines, we should scientifically prune them, cutting off some unnecessary vines to avoid nutrient loss and prevent it from affecting root enlargement.
