Detailed Explanation of the Latest Key Technical Points for Fertilizing Kudzu

Kudzu is a plant very similar to cassava, but kudzu is a Chinese medicinal herb with both medicinal and edible uses. In our daily lives, kudzu is often used to reduce fever, stop diarrhea, promote body fluid production and quench thirst, and to promote eruption of rashes, and it is also very effective when used for dry heaving. Now the scale of kudzu cultivation is constantly expanding, so if we want to increase the yield and quality of kudzu, fertilization can be said to be a very critical step. Today let us take a look at the fertilization techniques for kudzu.

1. Base fertilizer

The growth of kudzu requires a large amount of nutrients, and base fertilizer is the foundation of its high yield, so it must be applied in sufficient quantity. Base fertilizer is generally applied together with land preparation, and it can be said to account for half of the total fertilizer application, and it is mainly based on organic fertilizer, combined with an appropriate amount of inorganic fertilizer for broadcasting. When applying base fertilizer, we need to mix the organic fertilizer and inorganic fertilizer evenly, then scatter it in the selected planting site, carry out land preparation, and fully mix the fertilizer with the soil to improve soil fertility.

2. Full-stand seedling fertilizer

When the kudzu seedlings grow to about 20 cm, we need to carry out one topdressing. This topdressing needs to be carried out together with intertillage, weeding, and loosening of the soil, mainly to promote the growth of kudzu seedlings and ensure the uniformity of the seedlings in the field. Full-stand seedling fertilizer is generally applied by watering with manure and urine water plus a small amount of compound fertilizer, and it needs to be done in three applications, with each application controlled at about 200 jin, applied once every about 20 days. If conditions permit, seedling-promoting bacterial fertilizer can also be used, sprayed once every week, and after two consecutive times, the effect is very obvious.

3. Growth fertilizer

In order to promote the growth of kudzu, in the middle stage of kudzu growth we also need to properly apply growth fertilizer as topdressing, and at the same time also control the growth of kudzu vines, so that nutrients are concentratedly supplied to the roots and the yield of kudzu is increased. The growth fertilizer for kudzu is generally a ternary compound fertilizer of nitrogen, phosphorus, and potassium. We can use the method of watering after mixing with water, and can also use the method of trenching and broadcasting for topdressing, and the effects are all very good.

4. Later-stage topdressing

Kudzu needs multiple rounds of topdressing so as to promote the enlargement of kudzu and improve the yield and quality of kudzu. Generally, when the kudzu tubers are forming, we need to apply manure and urine water in holes, and apply topdressing once each month in the same way, for three consecutive times. Next, the fourth fertilization is best done with stable manure or plant ash as topdressing. Of course, if these are really unavailable, inorganic fertilizer containing phosphorus and potassium can also be used instead, which can promote the growth of kudzu tubers.

Kudzu is a crop with a relatively large fertilizer requirement, so during the planting process we must attach great importance to its fertilization. If kudzu experiences fertilizer deficiency during growth, the impact on its yield and quality is very great. Do you all understand the fertilization of kudzu now?
