Problems solved by technology

At present, in order to produce selenium-enriched melons, the method of foliar spraying inorganic selenium is adopted, and its disadvantages are very obvious. First, foliar spraying requires a relatively high content of selenium fertilizer, and high-concentration selenium fertilizer increases the cost of fertilizer use; secondly, because the leaves Surface spraying, selenium fertilizer is easy to sprinkle in the field, so just causes very big waste to field runoff water and soil; Again, often causes the residual amount of inorganic selenium to be large, and inorganic selenium has obvious poisonous effect to body, safety low, cannot be used in the production of organic selenium-enriched agricultural products

Embodiment 1

[0026] Embodiment 1: Preparation and production of organic selenium-enriched melon special fertilizer

[0027] Commercially available raw materials for preparing fertilizers, wherein nitrogen fertilizer can be one or more of urea, ammonium chloride; phosphate fertilizer can be one or more of monoammonium phosphate, diammonium phosphate, superphosphate and calcium magnesium phosphate fertilizer. Potassium fertilizer can be one or more of potassium sulfate, potassium chloride, potassium dihydrogen phosphate and potassium monohydrogen phosphate; trace elements can be boron, zinc, manganese, iron, copper or molybdenum and other trace element fertilizers One or several kinds of selenium-containing flax cakes have a total selenium content greater than 0.0015%.

[0028] The weight ratio of each component of selenium-containing flax cake, nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and trace elements is:

[0029] Selenium flax cake 30-70

[0030] Nitroge...

Embodiment 2

[0037] Embodiment 2: Field production test of organic selenium-enriched melon

[0038] Field test site: Xinhe Village, Laogang Town, Pudong New Area, Shanghai, with medium fertility.

[0039] The tested melon variety: Elizabeth.

[0040] In the present embodiment, the selenium-enriched organic and inorganic special fertilizer is made up of the following raw materials in parts by weight: 40 parts of industrialized decomposed selenium-containing flax cakes, 19 parts of urea, 8 parts of diammonium phosphate, 3 parts of superphosphate, 29 parts of potassium sulfate, 0.5 part of borax and 0.5 part of zinc sulfate are granulated by agglomeration method or granulated by extrusion method, and the equipment and technology are the same as the existing equipment and technology for producing organic-inorganic compound fertilizer. Add the selenium-containing flax cake that has been decomposed in the factory into the granulator in proportion, and mix it with urea, diammonium phosphate,...

Abstract

The invention discloses a special fertilizer for producing organic selenium-enriched melons and a preparation method thereof. The preparation method is characterized by comprising the following steps of taking flax cakes containing selenium as selenium sources, reasonably proportioning N, P and K, mixing, and pelleting, thereby obtaining the special fertilizer. The selenium-enriched, organic and inorganic special fertilizer disclosed by the invention not only can effectively increase the selenium content of melon fruits, but also can promote the accumulation of soil organic matters, thereby improving the structure and physicochemical properties of soil. According to the selenium-enriched, organic and inorganic special fertilizer prepared by the preparation method, the production cost of the fertilizer cannot be increased, thereby facilitating popularization.

Description

[0001] technical field [0002] The invention belongs to the technical field of fertilizer production, in particular to a special fertilizer for producing organic selenium-rich melons and a preparation method thereof. Background technique [0003] Selenium is an essential trace element for the human body. It is a multifunctional nutrient element for life. It has anti-oxidation, regulates the body's metabolism, improves the body's immunity and disease resistance, improves the reproductive function, resists tumors, and prevents endemic diseases (such as Keshan disease , Kashin-Beck disease), delaying aging, antagonizing toxic elements and other functions. Studies in recent years have shown that selenium is closely related to the structure and function of the cardiovascular system and the occurrence of diseases. Selenium enzyme-glutathione peroxidase has the functions of reducing peroxide, resisting lipid peroxidation and protecting cell membrane. The heart is very sensitive ...
