Special ecological fertilizer for maca as well as preparation method and application thereof

Abstract

The invention belongs to the field of fertilizers for crops and particularly relates to a special ecological fertilizer for maca as well as a preparation method thereof. The special ecological fertilizer is prepared by mixing decomposed manure, agricultural and forestry wastes, urea, a phosphate fertilizer, potassium humate, medium trace elements, an activating agent and a water retaining slow-release agent at a certain weight ratio. A compound fertilizer with charcoal serving as the substrate is prepared by carbonizing the agricultural and forestry wastes into charcoal and fully mixing the charcoal with the decomposed manure and the chemical fertilizers. The content of total nitrogen and available phosphate in soil can be increased due to the application of the compound fertilizer. The loss of nutrients in the compound fertilizer due to elution can be reduced, and the utilization rate of the compound fertilizer can be increased. The water retaining slow-release agent is added into the compound fertilizer to form the ecological fertilizer with water retaining and slow releasing capacities. The special ecological fertilizer for maca is reasonable in formula, contains multiple balanced nutrients, is improved in utilization rate significantly and can be used for greatly improving the yield and quality of maca. In addition, the special ecological fertilizer for maca can be used for improving the environment of soil, enhancing the fertilizer retaining and supplying capacity and buffering capacity of soil, reducing pests and diseases and increasing the economic benefit of maca due to long-term application.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a special ecological fertilizer for maca and its preparation method and application. Background technique [0002] Maca is an annual or biennial herbaceous plant belonging to the Brassicaceae genus. It is a functional food with rich nutrition, unique taste and multiple medicinal and health care values. According to modern scientific research, Maca has a variety of nutrients, such as protein, amino acid, starch, vitamins, and various minerals. Alkali, mustard oil, etc., have pharmacological effects such as improving immunity, improving fertility, improving sexual function, improving menopausal syndrome, improving sleep, regulating endocrine, anti-fatigue, anti-oxidation, and anti-tumor. [0003] Maca has become a new star in the international health care product market due to its special functions and effects. However, due to the special growth environment of Maca, it needs to grow in ...

AI Technical Summary

Problems solved by technology

However, the composition of decomposed manure and livestock manure is complex, and the fertilizer effect varies greatly. The application of decomposed fertilizer alone cannot meet the law of maca growth, and the nutrient content of fertilizer is low, and the fertilizer effect is slow and lasts for a long time, which is not conducive to the direct absorption of maca.

The amount of decomposed fertilizer is large, and about 2000-3000 kg of decomposed fertilizer is needed per mu of maca. The fertilization operation is heavy. At the same time, the decomposed manure contains a large amount of organic matter, and direct discharge will cause water pollution and eutrophication

[0004] According to the above, the fertilization of artificially planted maca in my country is mainly based on decomposed organic fertilizer, and the application of decomposed organic fertilizer alone cannot meet the law of maca growth, and the nutrient content of fertilizer is low, and the release of fertilizer effect is slow, so the yield of maca cannot be significantly increased.
