Description
Technical Field
The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for reducing cadmium in ligusticum wallichii and an application method thereof.
Background
Rhizoma Ligustici Chuanxiong is dry rhizome of Umbelliferae plant rhizoma Ligustici Chuanxiong, has pungent and warm nature, and enters liver and gallbladder meridian. Promote blood circulation and move qi, dispel wind and alleviate pain. Can be used for treating headache, rheumatalgia, amenorrhea, dysmenorrhea, and traumatic injury with swelling and pain. The rhizoma Ligustici Chuanxiong contains effective components such as ligustrazine and ferulic acid, 1493 Chinese medicinal preparations are recorded in 2015 of Chinese pharmacopoeia, wherein 239 preparations containing rhizoma Ligustici Chuanxiong account for 16.01%; 3798 Chinese medicinal preparations are collected from the drug standard Chinese medicinal preparation of ministry of health, wherein 487 preparations containing the ligusticum wallichii account for 12.82%, 8 and 16 days in 2019, and published by the commission of national pharmacopoeia about 0212 public draft of verification rules of medicinal materials and decoction pieces, the limits of heavy metals and harmful elements (lead, cadmium, arsenic, mercury and copper) are required to be checked for plant medicinal materials, and modern pharmacological studies show that the ligusticum wallichii has better curative effect on relieving angina pectoris of coronary heart disease, and has the effects of resisting thrombus, tumor, radiation and sedation, easing pain, improving immune system and the like. Chuan Xiong has been widely used in the treatment of cardiovascular and cerebrovascular diseases, such as Chuan Xiong Jing injection. In addition, the ligusticum wallichii has the health care effects of protecting liver, reducing blood fat and the like, and the health care products such as ligusticum wallichii tea, ligusticum wallichii wine, ligusticum wallichii sugar and the like have good markets. Meanwhile, the ligusticum wallichii has remarkable effects of whitening and preventing alopecia, can be developed into daily chemical products, and assigns the industrial value of the ligusticum wallichii.
The ligusticum wallichii is one of the traditional Chinese medicinal materials in the great district of Sichuan, is mainly produced in the places such as Dujiang weir, Pengzhou, Meishan mountain and the like, has the characteristics of outstanding regional characteristics and concentrated land characteristics, has the annual planting area of more than 8 ten thousand mu, the annual output of 8000-12000 tons, accounts for more than 90 percent of the total output of the whole country, has the annual output value of 2 hundred million yuan, and has the first output and the second output in all the medicinal materials in the district of Sichuan. With the gradual expansion of cultivation and planting area, the ligusticum wallichii is a main economic crop and income source for farmers in production areas. The market demand of the ligusticum wallichii is large, and 20-30 percent of the ligusticum wallichii is used in the traditional Chinese medicine prescription. With the popularization and implementation of the policy of 'healthy China', the health care consciousness of people is enhanced, the demand of the ligusticum wallichii is increased day by day, the ligusticum wallichii is one of the bulk medicinal materials exported in China, and the export amount of the ligusticum wallichii reaches 2747 ten thousand dollars in 2016. However, the export market is seriously atrophied due to the influence of the problems of excessive heavy metals and the like, and with the implementation and popularization of the project, a large amount of high-quality green ligusticum wallichii traditional Chinese medicinal materials produced reach the 'import and export green industry standards of medicinal plants and preparations', the development of the foreign market of the ligusticum wallichii traditional Chinese medicinal materials is promoted, and the export foreign exchange is realized.
The problem of the quality of the produced rhizoma ligustici wallichii is often caused by the pollution of the soil in the production area. In 2017, the export of the ligusticum wallichii is returned for 2 times due to quality problems, and the image of the traditional Chinese medicine in China is seriously influenced. According to the report, the heavy metal cadmium (Cd) content in the rhizomes of the ligusticum wallichii medicinal materials in the 4 main production areas of Sichuan exceeds the standard. At present, researches on the problem of excessive heavy metal cadmium in the ligusticum wallichii mainly focus on the aspects of determination and scheme of cadmium content in the ligusticum wallichii medicinal materials, absorption and enrichment rules of the ligusticum wallichii heavy metal cadmium, influence of the heavy metal cadmium on yield and quality of the ligusticum wallichii and the like, few researches on technologies for reducing the content of the ligusticum wallichii heavy metal cadmium are carried out, only quicklime or potassium dihydrogen phosphate-sodium hydroxide buffer solution is used for improving soil PH, reducing Cd effectiveness and inhibiting the absorption of the ligusticum wallichii to Cd are used, the technical solution way is single, the effect is not obvious, and the method does not conform to green agricultural development. Therefore, the problem of absorption of heavy metal cadmium by the ligusticum wallichii plants is urgently solved.
