Embodiment 1

[0087] A high-nutrient compound selenium fertilizer is characterized in that: it comprises the following components according to the weight ratio:

[0088] Organic material 55%

[0089] Inorganic materials 42%

[0090] Medium and trace elements 2.989%;

[0091] Selenium 0.011% pure selenium (1 gram of pure selenium is equivalent to 3.4 grams of selenite, which is equivalent to about 1 gram of selenium oxide).

[0092] The technical indicators of the finished product are: about 40% of nitrogen, phosphorus, potassium + selenium + medium and trace elements, about 50% of organic matter, about 30% of humic acid, about 16% of crude protein (cell protein), pH5.8~ 6.7.

[0093] The organic material in the present invention includes crop stalks, cake fertilizer, poultry and livestock manure, etc., with a proportion of 20%-50% by weight.

[0094] The crop stalks in the organic material of the present invention are composed of at least one of the following materials or any combi...

Embodiment 2

[0146] A high-nutrient compound selenium fertilizer, comprising the following components according to the weight ratio:

[0147] Organic material 60%

[0148] Inorganic material 45%

[0149] Medium and trace elements 4.975%

[0150] Selenium element 0.025% pure selenium (1 gram of pure selenium is equivalent to 3.4 grams of selenite, which is equivalent to about 1 gram of selenium oxide).

[0151] The technical indicators of the finished product are: about 40% of nitrogen, phosphorus, potassium + selenium + medium and trace elements, about 50% of organic matter, about 30% of humic acid, about 16% of crude protein (cell protein), pH5.8~ 6.7.

[0152] A kind of preparation method of high nutrient compound selenium fertilizer of the present invention is characterized in that:

[0153] 1. Weigh the crushed, fermented and decomposed organic materials and inorganic materials respectively, add water according to about 10% of the total amount of organic materials and inorganic m...

Embodiment 3

[0170] As mentioned above, the object of the present invention is also achieved.

[0171] A high-nutrient compound selenium fertilizer, comprising the following components according to the weight ratio:

[0172] Organic material 45%

[0173] Inorganic materials 53%

[0174] Medium and trace elements 1.975%

[0175] Selenium element 0.025% pure selenium

[0176] The using method of a kind of high nutrient compound selenium fertilizer of product of the present invention is as follows:

[0177] The selenium in this highly available selenium fertilizer can last for 5-6 years in the soil. It is mainly suitable as a base fertilizer, and it is most suitable for tea trees to be used as a selenium-enriched tea fertilizer. It can reach the standard of selenium-enriched tea within 3 years after one application. Because of high nutrition, spring tea can be used as base fertilizer without additional topdressing; summer and autumn tea can be topdressed with strong bud fertilizer. Spr...

Abstract

The invention discloses a high nutrient compound selenium fertilizer comprising selenium, nuisanceless organic material-inorganic material and medium and trace elements, and a preparation method thereof. The high nutrient compound selenium fertilizer comprises 45-60 wt% of organic material, 55-35 wt% of inorganic material, 1-6 wt% of medium and trace elements, and 0.011-0.025 wt% of purified selenium. The fertilizer disclosed in the invention can increase yield efficiently, and allow the applied plant to contain selenium element which has health care effect to human body. The fertilizer adopts a plurality of internal adsorptions to protect selenium to let the selenium in the selenium fertilizer be effective, has good intermiscibility and degradability, keeps selenium from fix, and obviously improves the biological absorption utilization rate of selenium of plants (including tea).

Description

technical field [0001] The invention relates to an artificial selenium-increasing fertilizer, especially a high-nutrient compound selenium fertilizer composed of selenium element, pollution-free organic material-inorganic material and medium and trace elements, which is mainly suitable for tea production and is also suitable for bulk food crops Fertilizer for rice, wheat, corn, potatoes, fruit trees, and Su vegetables. Background technique [0002] From the 70s of last century ’ Since the establishment of selenium (Se) as an essential trace element in human and animal life activities in the 1990s, clinical experimental medicine has continuously proved that selenium is a "life element". If the human body lacks selenium, it will cause dysfunction of important organs, which can cause more than 40 diseases. Various diseases: cancer, coronary heart disease, cardiomyopathy, arteriosclerosis, diabetes, leukemia, viral hepatitis, etc. [0003] However, about 42 countries in the wo...
