Embodiment 1

[0017] The selenium-containing medicinal fertilizer is composed of the following raw materials: 82.5 kg of compound fertilizer, 1.0 kg of sodium selenite, 10 kg of zeolite powder, and 1.5 kg of chlorpronil.

[0018] The preparation steps are as follows:

[0019] 1.1. Mix 1.0kg sodium selenite, 1.5kg chlorfenapyr and 10kg zeolite powder evenly to make a selenium-containing pesticide mixture;

[0020] 1.2. Mix 82.5 kg of compound fertilizer raw materials with the selenium-containing pesticide mixture in step 1.1, and add them into a granulator to granulate to make a selenium-containing medicinal fertilizer.

Embodiment 2

[0022] The selenium-containing medicinal fertilizer is composed of the following raw materials: 89.7 kg of compound fertilizer, 0.1 kg of sodium selenite, 15 kg of zeolite powder, and 0.2 kg of chlorpronil.

[0023] The preparation steps are as follows:

[0024] 1.1. Mix 0.1kg sodium selenite, 0.2kg chlorfenapyr and 15kg zeolite powder evenly to make a selenium-containing pesticide mixture;

[0025] 1.2. Mix 89.7 kg of compound fertilizer raw materials with the selenium-containing pesticide mixture in step 1.1, and add them into a granulator to granulate to make a selenium-containing medicinal fertilizer.

Embodiment 3

[0027] The selenium-containing medicinal fertilizer is composed of the following raw materials: 85 kg of compound fertilizer, 0.5 kg of sodium selenite, 12 kg of zeolite powder, and 0.8 kg of chlorpronil.

[0028] The preparation steps are as follows:

[0029] 1.1. Mix 0.5kg sodium selenite, 0.8kg chlorfenapyr and 12kg zeolite powder evenly to make a selenium-containing pesticide mixture;

[0030] 1.2. Mix 85kg of compound fertilizer raw materials with the selenium-containing 36 pesticide mixture in step 1.1, and add them into a granulator to granulate to make a selenium-containing medicinal fertilizer.

[0031] Compared with common agricultural products, the biological organic selenium content in the selenium-containing medical fertilizer agricultural products of the present invention can be increased by 5-10 times, and its lysine and amic acid contents can be increased by 50%; The human body's physiological requirement for selenium is 50-200 mg / a proposed by the United Nati...

Abstract

The invention provides a selenium-containing insecticide-fertilizer and a preparation method thereof. The fertilizer consists of the following raw materials: a composite fertilizer, sodium selenite, zeolite powder, and chlorine cyanide. The method is as below: uniformly mixing sodium selenite, chlorine cyanide and zeolite powder to obtain a selenium-containing pesticide mixture; evenly mixing the composite fertilizer and the selenium-containing pesticide mixture; and adding into a granulator for granulation to prepare the selenium-containing fertilizer. The invention has the advantages that selenium and insecticide-fertilizer are organically combined, so that inorganic selenium can be absorbed and transformed by the crops in the form of fertilizer, so as to generate bio-organic selenium-enriched agricultural products.

Description

technical field [0001] The invention relates to a selenium-containing medicinal fertilizer and a preparation method thereof. Background technique [0002] Medicinal fertilizer is a combination of pesticide and chemical fertilizer. It has the dual functions of pesticide and chemical fertilizer. It has been widely used in recent years. Selenium (se) is an indispensable life element for the human body. It is directly mixed with the synthesis and metabolism of biological nucleic acids and biochemical enzymes, affecting Cell division, reproduction and inheritance, and has the physiological functions of anti-oxidation and scavenging free radicals. The main source of selenium for human body is nature, and two-thirds of the regions and populations in my country are in selenium deficiency and low selenium levels. For this reason, supplementing selenium scientifically and safely has become an important topic. As a result, various selenium supplement products came into being: seleniu...
