Embodiment Construction

[0006] A kind of bio-organic compound fertilizer containing organic selenium, it is characterized in that: take basic raw material mycelium amino acid mother liquor, stevia rebaudiana slag (special for tea), straw, humic acid, chicken manure etc. (proportioning: livestock and poultry manure 70% , mycelium amino acid mother liquor 20%, straw and stevia slag, etc. 10%) are inoculated with probiotics (total bacterial count > 500 million / g), and mixed with raw materials such as nitrogen, phosphorus, and potassium fertilizers (rice and wheat grains: urea 6.25kg, over Calcium phosphate 85.7%, potassium chloride 25kg, selenium and zinc nutritional liquid 300-500ml; tea leaves: ammonium sulfate 95kg, superphosphate 87.5kg, potassium sulfate 39kg, selenium and zinc (same as before), high-strength water-absorbing agent 10-20kg mixed Fully fermented and dehydrated in a bioreactor (25-60°C, 35 days) and then mixed and crushed to 50-75 mesh for granulation. The nitrogen content was determin...

Abstract

The invention relates to a selenium-rich special biological organic compound fertilizer for producing functional farm products. The compound fertilizer is prepared by the following steps of: stirring and mixing a mycelium-amino acid mother solution, humic acid, animal manure, probiotics and compounds containing selenium and zinc serving as major raw materials, matching raw materials such as nitrogen, phosphorus and potassium, a high-strength water absorber, crop straw, stevia residues and the like in a bioreactor; fully fermenting and dehydrating till the water content is controlled at about 14 percent; and smashing to 50-75 meshes, and pelletizing. A formula can be used for producing a culturing base fertilizer for functional farm products containing beneficial trace elements such as selenium-rich paddy rice, selenium-rich wheat and selenium-rich tea; and by applying the fertilizer reasonably, the crop yield can be increased by 10-50 percent, the selenium content of a product can be up to 100-500 mcg/kg, and the requirements of national selenium-rich farm products are met.

Description

technical field [0001] The invention relates to a kind of organic base material of farm poultry and livestock manure, straw and humus, adding probiotics, selenium and zinc inorganic compounds, converting inorganic selenium and zinc into organic selenium and zinc which are easily absorbed by crops, and then dehydrating and drying Add nitrogen, phosphorus and potassium chemical fertilizers, stir and pulverize them and process them into granular compound fertilizers containing organic selenium, which can be used as base fertilizers for producing selenium-enriched products for rice, wheat, tea and other crops. Background technique [0002] Selenium is one of the 15 essential trace elements for the human body, and is the most important antioxidant element for the human body. It has a strong detoxification and detoxification function. Cancer, liver disease, cardiovascular and cerebrovascular diseases, etc. are related to selenium deficiency. Selenium can resist aging and improve h...
