Problems solved by technology

At present, in order to produce selenium-enriched watermelons, 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 watermelon 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 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 fertilizer ...

Embodiment 2

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

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

[0039] Tested watermelon varieties: 8424.

[0040] In the present embodiment, the selenium-enriched organic and inorganic special fertilizer is composed of the following raw materials in parts by weight: 45 parts of industrialized decomposed selenium-containing flax cakes, 20 parts of urea, 12 parts of diammonium phosphate, 3 parts of superphosphate, 19 parts of potassium sulfate, 0.5 part of borax, 0.5 part of zinc sulfate, adopt granulation process or extrusion granulation process, its equipment and process are the same as existing equipment and process 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, superphosphate, p...

Abstract

The invention discloses a fertilizer special for producing organic selenium-rich watermelons and a preparation method thereof. The fertilizer special for producing organic selenium-rich watermelons is characterized in that the fertilizer uses selenium-containing benne cakes as a selenium source and is formed by reasonably matching and mixing nitrogen, phosphorus and potassium. The selenium-rich organic fertilizer can effectively selenium content in watermelon fruits, promote soil organic matter accumulation and improve soil structure and physicochemical property. The fertilizer producing cost is not increased when the selenium-rich organic special or inorganic special fertilizer is prepared, the fertilizer is a special fertilizer easy to popularize.

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 watermelons 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 s...
