[0005]1. The fertilizer period is short and the fertilizer utilization rate is low;
[0007]3. Single organic fertilizer has low nutrients and poor fertilizer efficiency;
[0008]4. The organic-inorganic compound fertilizer has poor fertilizer efficiency due to low content;
[0009]5. General fertilizers do not contain medium and trace elements to improve crop yield and quality or are incomplete;
[0010]6. Although some fertilizers can increase production, the oil yield has been maintained below 40%, which is difficult to increase

Abstract
The invention discloses a long-term biological slow-release fertilizer special for peanut and a preparation method thereof, belonging to the technical field of special fertilizer for crops. A urea-formaldehydecoated urea, a urea-coated Rhizobium inoculant composition, potassiumsulfate, calciummagnesiumphosphate, monoammonium phosphate, humic acid, ferroussulfate, zincsulfate, EDTA chelated manganese, borax, and molybdic acid are used as raw materials, the raw materials are mixed and stirred for 6-8 minutes until fully and evenly mixed, and then the raw materials are weighted and packaged to obtain finished products. Compared with the prior art, only once application of the fertilizer is needed, thus the fertilizer is conveniently applied, moreover peanuts are improved in yield and quality, so that the peanut specific long-term biological slow-release fertilizer and the preparation method thereof are worth popularizing.
Description
technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a special long-acting slow-release fertilizer for peanuts. Background technique [0002] Peanut is a leguminous crop, rich in fat and protein, widely used, and has a high status in the national economy. At present, a large number of peanuts are used to extract oil. Peanut oil has clear color, fragrant smell and delicious taste. It is a comparative Easily digestible cooking oil. Peanut oil contains more than 80% unsaturated fatty acids (including 41.2% oleic acid and 37.6% linoleic acid). In addition, it also contains 19.9% of saturated fatty acids such as palmitic acid, stearic acid and arachidic acid. The fatty acid composition of peanut oil is relatively good, which is easy for human body to digest and absorb. [0003] At present, the average yield of peanuts in my country is about 3000kg / ha, and its potential for increasing yield is relatively large, an...
