Fertilization law of Pinellia ternata

In rural areas, there is also a lot of wild Pinellia ternata in the cultivated land and in the mountains, but because of their scarcity, they can not meet the needs of pharmaceutical factories, so many farmers have begun to plant Pinellia ternata artificially. Artificial cultivation of Pinellia ternata must master the law of fertilization.

1. Fertilization law of Pinellia ternata

1. First of all, Pinellia ternata needs a large amount of fertilizer, but only shallow fertilizer is needed. The root of Pinellia ternata is relatively short, so when applying fertilizer, you should not apply too much fertilizer or deep ploughing, you only need to apply fertilizer about 5 centimeters above the surface, but be careful not to hurt the root and do not apply fertilizer to the root. Pinellia ternata has a large demand for fertilizer, but remember to fertilize frequently at ordinary times, but the dosage should be less, which can help Pinellia ternata take root quickly, absorb fertilizer and water, and grow better.

2. Secondly, fertilize before cultivation and pay attention to topdressing. Of course, it is necessary to master some fertilization techniques when fertilizing. First of all, fertilization is not blind fertilization. Some base fertilizers can be applied before planting. The basic fertilizers are mainly composed of fallen leaves or animal manure or crop straw. After they are ripe, about 500 kilograms per mu of field can be applied to improve the soil structure.

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

4. The last topdressing can be from September to October, during this period, people can prepare some special fertilizer by themselves, so as to ensure the growth and expansion of tubers, and then about 1 kilogram and 3 jin per mu of land can be applied, but it should be noted that fertilizing needs to be 10 centimeters away from the base of the stem, so as to ensure that the stem will not be burned and the root will not be burned either.

Finally, master the skills of fertilization. Generally speaking, Pinellia ternata is generally planted in ridges in rural areas, and it is generally only necessary to dig two small ditches of about 5 cm on both sides of the ridges, so that fertilization can ensure uniform and rapid fertilization, and small holes can also be dug next to Pinellia ternata plants. this can make the absorption of Pinellia ternata more complete and complete. Fertilizer can also be dissolved in water, Pinellia ternata can grow faster.
