Embodiment 1

[0022] Embodiment 1 (referring to the corresponding raw materials and parts by weight of Embodiment 1 in Table 2): Pour 345 parts of biogas slurry concentrates into the mixing tank, add 10 parts of suspending agent, stir for 5 minutes, leave standstill for 5 hours, and stir while stirring Add 110 parts of urea, 195 parts of ammonium polyphosphate, 280 parts of KCI, 5 parts of borax, 10 parts of ZnSO 4 ·7H 2 O, finally slowly add 45 parts of fulvic acid, stir well and serve.

[0023] All the remaining examples 2-7 are made with reference to the corresponding raw materials and parts by weight of Example 2-7 in Table 2, and are made in the same way as in Implementation 1, except that the stirring time of adding suspending agent in the biogas slurry concentrate is 5-10 minutes and it is considered uniform The degree of selection, the standing time is within 5-10 hours, depending on the suspension situation. Among the seven examples, examples 1, 2, and 3 are preferred.

Abstract

The invention relates to a maize fulvic acid polyelement composite liquid base fertilizer taking concentrated biogas slurry as a base solution, which is prepared from the following raw materials in portion by weight: 195 to 200 portions of ammonium polyphosphate, 110 to 115 portions of urea, 280 to 285 portions of potassium chloride, 5 to 6 portions of borax, 10 to 11 portions of heptahydrate zinc sulphate, 10 to 12 portions of suspending agent, 345 to 321 portions of the concentrated biogas slurry and 45 to 50 portions of fulvic acid. The liquid base fertilizer contains 352 to 368 g/L of macroelement, 53 to 57 g/L of the fulvic acid, and 11 to 21 g/L of water-insoluble matters; and the pH value of the fertilizer subjected to dilution by 250 times is 6.2 to 6.5. The production of the fertilizer comprises the following steps: comprehensive analysis of soil agricultural-chemistry characteristics, maize fertilization experiment, calculation of fertilizer proportion, selection of raw materials, material preparation, and mixing and preparation; and water is used for diluting the fertilizer by 200 times, and hole application is performed on the diluted fertilizer when hole sowing is performed on maize seeds at the same time, or the fertilizer is applied at a dosage of 65 kilogram/mu when water is irrigated to field. The fertilizer has no secondary pollution, and has reasonable and even application; and the invention provides a base fertilizer containing the macroelement, microelement and fulvic acid active substances to promote the growth and production increase of maize.

Description

technical field [0001] The invention relates to a fertilizer, which is a fulvic acid multi-component compound liquid base fertilizer which takes biogas slurry concentrate as base liquid and its production and use method. Background technique [0002] Biogas slurry is the organic residue after anaerobic fermentation of plant stalks, human and animal manure and other raw materials in the biogas tank to produce biogas. It is a high-quality organic fertilizer. It is directly applied to the field for a long period of time. Serious pollution; and in order to reduce transportation costs, such direct application is often concentrated in the nearby biogas tanks, resulting in uneven fertilizer supply; biogas slurry is directly applied as a liquid fertilizer, and its macroelements, trace elements and other beneficial components The low content and unreasonable ratio cannot meet the actual needs of crop nutrient balance, which is not only unfavorable for crop growth but also causes wast...
