Qianhu needs farm fertilizer and compound fertilizer. Before planting Peucedanum, it is necessary to apply sufficient base fertilizer in the soil, and it is best to choose the decomposed farmyard fertilizer as the base fertilizer. In the process of growth, Qianhu has a small demand for chemical fertilizer. Diluted pig and cow manure can be applied in the early stage of growth, and an appropriate amount of urea and compound fertilizer can be applied in combination with intercropping and weeding after seedling emergence. Compound fertilizer should be combined with unit fertilizer to ensure that the nutrients absorbed by Qianhu are comprehensive and balanced. 1、 What fertilizer does Qianhu apply? Farm fertilizer has the advantages of large quantity, wide source and low application cost. At the same time, it also contains comprehensive nutrients. It is more suitable as a base fertilizer. Because the nutrients in farm manure are mostly organic matter, it needs to go through the steps of microbial decomposition and chemical fermentation in the soil before it can be absorbed and utilized by Qianhu. This property makes the fertilizer effect of farmyard fertilizer longer and can provide sufficient nutrients for Peucedanum in the whole growth stage. In addition, organic fertilizer can also improve soil quality and promote the growth and development of Peucedanum.
Before the emergence of Peucedanum, only some manure and urine water need to be applied. After the emergence of Peucedanum, compound fertilizer and unit fertilizer need to be applied together. When meeting the needs of Qianhu for nitrogen, phosphorus and potassium, we should also pay attention to the supplement of trace elements to promote the high and stable yield of Qianhu. 2、 How to fertilize Peucedanum? Because Peucedanum needs less fertilizer, it is sensitive to the concentration of fertilizer. When the concentration of fertilizer is too high, it will cause the root of Peucedanum to burn and produce diseases. Therefore, when fertilizing Qianhu, it is best to adjust the amount, type and times of fertilizer application according to the different needs of different growth periods. The principle of thin and frequent application should be followed to improve its yield and quality. At the same time, fertilization needs to be combined with soil loosening to make better use of fertilizer. Be careful when loosening the soil to avoid damaging the root of the front beard. （QianHuShiShenMeFei）
