Problems solved by technology

At present, in order to produce selenium-enriched strawberries, 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 S...

Embodiment 1

[0026] Embodiment 1: Preparation and production of organic selenium-enriched strawberry 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. species; potassium fertilizer can be one or more of potassium chloride, potassium dihydrogen phosphate and potassium monohydrogen phosphate; trace elements can be one of trace element fertilizers such as boron, zinc, manganese, iron, copper or molybdenum or several types, the selenium-containing flax cake has 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] Nitrogen fe...

Embodiment 2

[0037] Embodiment 2: field production test of organic selenium-enriched strawberry

[0038] Field test location: Qinyi Village, Heqing Town, Pudong New Area, Shanghai, with medium fertility.

[0039] Strawberry varieties for testing: Red Cheek.

[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 decomposed selenium-containing flax cakes in factory, 18 parts of urea, 13 parts of diammonium phosphate, 3 parts of superphosphate, 25 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 p...

Abstract

The invention discloses a special fertilizer for producing organic selenium-enriched strawberry and a preparation method thereof. The special fertilizer is characterized by being prepared by the following steps of: with selenium-containing flax bread as a selenium source, mixing and pelletizing by reasonable proportion of nitrogen, phosphorus and potassium. The selenium-enriched inorganic and organic fertilizers disclosed by the invention not only can effectively improve selenium content in strawberry fruit, but also can promote accumulation of soil organic matters, and improve the soil structure and the physicochemical property. The inorganic and organic selenium-enriched fertilizers prepared by the preparation method do not increase the production cost of the fertilizer, and are special fertilizers which are easy to promote.

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-enriched strawberries 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 ...
