Water-flush formula fertilizer special for Chinese herbal medicine Andrographis paniculata

Abstract

The invention relates to a water-flush formula fertilizer special for a Chinese herbal medicine Andrographis paniculata. The fertilizer comprises the following effective elements by weight: 23.0-28% of nitrogen; 6.0-10.0% of phosphor, measured in P2O5; 10.0-15.0% of potassium, measured in K2O; 1.2-3.5% of sulfur, measured in SO4<2->; 0.2-1.0% of zinc, measured in ZnO; 0.5-1.3% of manganese, measured in MnO; and 2.1-5.6% of calcium, measured in CaO. The fertilizer of the invention is a formula fertilizer special for Andrographis paniculata and other Chinese herbal medicines, and is also suitable for field water-flush appilication. Combining irrigation and fertilization, the fertilizer in the invention has complete nutrient component, rational nutrient proportioning and high fertilizer utilization rate, and is in line with the nutrient absorption rules of Andrographis paniculata and other Chinese herbal medicines. The fertilizer provided in the invention can promote the growth and development of Andrographis paniculata, increase output and economic benefits, raise drug effect component content like andrographolide, and can simultaneously reduce the unfavorable influences to the environment as a result of excess nitrogen application or improper fertilization, thus mitigating environmental pollution and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special formula fertilizer for flushing and application of the Chinese herbal medicine Andrographis paniculata. Background technique [0002] Chinese herbal medicine-Andrographis paniculata is the whole herb of the Andrographis paniculata plant of the family Acanthaceae, also known as Yijianxi, Lamane, etc. It is a perennial herb, native to India and other places, and cultivated in my country to become an annual plant.

It is bitter in taste and cold in nature. One of the commonly used drugs and one of the first choice anti-virus drugs is the raw material of the pharmaceutical industry. Many traditional Chinese medicines and proprietary Chinese medicines contain Andrographis paniculata or its extra...

Problems solved by technology

[0005] However, because Andrographis paniculata is a plant that prefers fertilizer and moisture, the harvest is stems and leaves above the ground. In order to pursue high yield one-sidedly, many farmers apply a large amount of nitrogen fertilizer, and do not apply or apply very little phosphorus, potassium and trace element fertilizers. The ratio of nitrogen, phosphorus and potassium is serious. Imbalance and lack of trace elements lead to a sharp drop in the effective ingredient of Andrographis paniculata - andrographolide, the commerciality of the medicinal material deteriorates, and it even becomes a pile of waste grass with no medicinal value, causing heavy losses to farmers

Unreasonable fertilization methods such as blind fertilization, excessive fertilization and single nitrogen fertilizer application lead to poor fertilizer efficiency and low fertilizer utilization rate, which exacerbates the imbalance of soil nutrients, which not only limits the further increase of Andrographis paniculata yield and lactone content, but also reduces the fertilization rate. The economic benefits and farmers' planting income, at the same time, a large amount of nitrogen is lost with water or leached to groundwater, polluting water sources and the environment, and affecting the sustainable development of agriculture
