Scientific application of manure and urine fertilizer in the medicine field can improve the disease resistance of the medicine, reduce the nitrate content, and improve the quality of the medicine. However, it is worth noting that if the manure and urine fertilizer are directly applied to the medicinal plants, the medicinal materials will be contaminated and the germs will spread. Therefore, it is necessary to apply manure and urine.
Treatment before application. In order to effectively kill parasitic eggs and infectious bacteria in the manure and urine, it is necessary to carry out detoxification treatment before application. High temperature composting and septic tank sealing are usually used. It is also possible to use a poison treatment method, that is, to treat feces and urine fertilizers with substances that are toxic to parasites and pathogens, such as adding 200 ml of formalin per 100 kg of manure, sealing for 1 day or adding 50% of trichlorfon tablets 2 g of storage 2 In the day, you can also add 1 kg of urea for 3 days. Where there are conditions, it is possible to combine the fertilizer with the biogas fermentation, and it is preferable to apply the converted organic fertilizer and biogas residue.
Use ditch and acupoint fertilization. According to the size of the medicinal plant and the wet condition of the soil, it is necessary to dilute the water when applying the decomposed manure and urine, ditch or dig a hole, cover the soil, prevent the loss of fertilizer, and improve the utilization rate of manure and urine. In the seedling stage of the medicinal materials, the manure and urine fertilizer should be applied at a low concentration, and the dosage should be less to avoid burning the seedlings. In addition, human urine contains high levels of salt, and it is not appropriate to apply chlorine, such as ginger, turmeric, sand ginger, and amomum, so as not to affect product quality.
Avoid using sewage diluted fertilizer. Sewage contains a large number of germs, eggs, poisons and heavy metal ions, which can easily induce pests and diseases, cause soil pollution, and even affect the crops of the next season. Therefore, whether it is industrial sewage or domestic sewage, it can not be used as a medicinal material and fertilizer for water without harmless treatment.
