Selenium-enriched disease-resistant base fertilizer for rice and preparation method thereof

Abstract

The invention provides a selenium-enriched disease-resistant base fertilizer for rice and a preparation method thereof and belongs to the field of farming. The base fertilizer is prepared from the following raw materials in parts by weight: 20-25 parts of rice stems, 15-20 parts of furfural residues, 25-30 parts of mushroom residues, 10-12 parts of rape seed cakes, 10-12 parts of sweet potato vines, 8-10 parts of peat, 12-15 parts of duck manure, 10-13 parts of sheep manure, 8-10 parts of night soil, 5-7 parts of fructus ulmi, 2-4 parts of wild carrot fruits, 15-20 parts of potassium fulvic acid, 10-15 parts of ammonium phosphate, 3-5 parts of zinc sulfate, 0.01-0.02 part of sodium selenite, 0.007-0.009 part of a rot promoter and 205-215 parts of water, wherein the rot promoter is prepared by mixing the following raw materials: iron phosphate, magnesium nitrate, ammonium sulfate, potassium sulfite and ammonium hydrogen phosphate. The formula of the base fertilizer provides sufficient nutrient elements, can achieve the effects of improving the survival rate of rice, preventing diseases, saving fertilizers, improving the yield, increasing selenium content in rice and improving the nutritive value of the product, is applicable to large-scale systematic planting and can increase the yield and income for farmer households.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of agricultural planting, in particular to a selenium-rich and disease-preventing base fertilizer for rice and a preparation method thereof. [0003] 【Background technique】 [0004] Selenium is an essential trace mineral nutrient for the human body. The "Daily Dietary Nutrition Supply" revised by the Chinese Nutrition Society in October 1998 listed selenium as one of the 15 daily dietary nutrients. The appropriate daily intake of selenium is 50-250μg. The total content of selenium in the human body is 6-20mg, 70% of the human body lacks selenium element. Once the human body lacks selenium element, it will easily lead to the decline of immunity and cause various diseases, such as cardiovascular disease, liver disease, cataract, Pancreatic diseases, diabetes, reproductive system diseases, etc. Since there is no organ in the human body that can store selenium for a long time, the selenium needed by the huma...

Problems solved by technology

In the process of planting, the quality of plant growth has an important relationship with whether the fertilizer is scientific or not. If it is not managed properly, it may cause the flood of plant diseases and affect the yield and quality of crops. At present, there are few studies on selenium-rich disease-preventing fertilizers for rice. When fertilizing, the type of fertilization is only determined according to the general planting experience. Once a disease occurs, pesticides will be used indiscriminately, which will eventually endanger people's health; Meet the needs of the market
