Fertilization Rules and Key Points of Scientific Fertilization Techniques for Pinellia

In rural areas, a lot of wild Pinellia also grows in farmland and in the mountains, but because their numbers are scarce and cannot meet the demand of pharmaceutical factories, many farmer friends have also begun to cultivate Pinellia artificially. When cultivating Pinellia artificially, one must master the fertilization rules for Pinellia.

1. Fertilization Rules for Pinellia

1. First, Pinellia has a high fertilizer requirement, but only shallow fertilization is needed. The roots of Pinellia are relatively short, so when fertilizing, do not apply too much fertilizer and do not deep-plow; simply fertilize at about 5 cm from the soil surface, but be careful not to damage the roots and do not apply fertilizer directly on top of the roots. Pinellia has a relatively large demand for fertilizer, but in normal times remember to fertilize frequently while using a small amount each time. This can help Pinellia take root quickly, absorb fertilizer and water, and grow better.

2. Second, fertilize before cultivation and pay attention to topdressing. Of course, when fertilizing, one must also master some fertilization techniques. First, fertilization is not carried out blindly. Before planting, some base fertilizer can be applied. The main components of the base fertilizer are fallen leaves, animal manure, or crop straw. After they are decomposed, apply about 500-600 jin per mu, which can improve the soil structure.

3. During the seedling stage, topdressing is needed. This can promote the growth of Pinellia seedlings. In summer, because of rainfall and water irrigation, some nutrients may be washed away, so at this time topdressing is needed to supplement nutrition, mainly by applying phosphorus and potassium fertilizer and supplementing trace elements such as calcium.

4. The last topdressing can be done in September-October. During this period, people can prepare some special fertilizer themselves, which can ensure the growth and expansion of the tubers. Then about 1-3 jin can be applied per mu. However, it should be noted that when fertilizing, one must stay 10 cm away from the base of the stem. This can ensure that the stem will not be burned, and likewise the roots will not be burned.

Finally, master the fertilization techniques. Generally speaking, in rural areas Pinellia is usually planted in ridges and rows. Usually, it is only necessary to dig two small furrows about 5 cm deep on both sides of the field ridge. Fertilizing in this way can ensure even and rapid fertilization. Small pits can also be dug beside the Pinellia plants for application, which allows Pinellia to absorb more completely and fully. Fertilizer can also be dissolved in water, so that Pinellia can grow faster.
