Problems solved by technology

At present, traditional cultivation methods are mostly used in the production of angelica, and various types of fertilizers are used. The nitrogen, phosphorus and potassium inorganic compound fertilizers available on the market are mainly used, which can meet the growth needs of angelica in a short period of time. Long-term application will damage the soil environment, which is not conducive to Angelica root growth and nutrient absorption, and a large amount of irrational application of inorganic fertilizers, especially the excessive application of phosphorus fertilizers such as diammonium phosphate, will make angelica seedlings grow rapidly, significantly increase the bolting rate of angelica, accelerate the lignification process of roots, and increase the bolting rate , causing problems such as low yield and quality decline of Angelica sinensis, such as Chinese Patent Publication No. CN101891538A discloses a special fertilizer for long-acting slow-release Angelica sinensis and its preparation method and application. The special fertilizer contains urea, superphosphate or diammonium phosphate , potassium sulfate, fertilizer long-acting agent NAM and medium and trace elements, its main purpose is to overcome the defects such as low fertilizer utilization rate, poor fertilizer effect persistence and inconvenient application in the prior art, but does not take into account the impact of chemical fertilizers on Angelica sinensis in the early stage. The impact of bolting, and unreasonable application of chemical fertilizers will increase the bolting rate of Angelica sinensis, lignify the roots of Angelica sinensis, reduce the content of active substance ferulic acid, and affect the yield and quality of Angelica sinensis
[0004] According to the above, in order to improve the yield and quality of artificially cultivated Angelica sinensis, inorganic fertilizers should be applied rationally and the application rate of organic fertilizers should be increased. However, the organic fertilizers currently on the market have low nutrient content and slow fertilizer release, which cannot significantly increase the yield of Angelica sinensis.

Abstract

The invention belongs to the field of crop fertilizers, and particularly relates to an ecological fertilizer special for Chinese angelica and a preparation method of the ecological fertilizer. The special ecological fertilizer is prepared from decomposed cow dung, guano, rape seed cake, monosodium glutamate residue, chitosan, urea, potassium humate, fly ash, sodium selenite, nickel sulfate, manganese sulfate, zinc sulfate, copper sulfate, boric acid, an active factor and a soil conditioner according to certain weight ratio. The special ecological fertilizer is reasonable in formula and comprehensive and balanced in nutrition, provides slow release nitrogen, phosphate fertilizer and quick-acting potash fertilizer for growth of Chinese angelica, obviously improves the fertilizer effect utilization ratio, reduces the early-stage bolting rate of Chinese angelica, and increases the fresh weight of one piece of Chinese angelica; the active factors are added into the fertilizer, so that biosynthesis of a nutrient substance, namely ferulic acid, at the root part of Chinese angelica can be promoted, and the content of ferulic acid can be increased; meanwhile the soil conditioner in the fertilizer can improve the soil environment, so that disease and pest damage can be reduced, and the economic benefits of Chinese angelica can be improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a special ecological fertilizer for angelica and a preparation method thereof. Background technique [0002] Angelica is the dried root of Angelica genus in Umbelliferae. It is warm in nature and sweet in taste. It is a holy medicine for gynecological diseases commonly used in medicine. Angelica has a long history of cultivation in my country, and is mainly distributed in Gansu, Yunnan, Sichuan, Qinghai, Hubei, Shaanxi and other places, among which Minxian County, Gansu has the largest output. At present, Angelica sinensis has become one of the most concerned medicinal materials, and the cultivation of Angelica sinensis plays a vital role in the development of agricultural economy. [0003] At present, most of the supply of angelica in my country comes from artificial cultivation. With the continuous expansion of the cultivation scale, the yield and quality of angelica are showing a d...
