Description

A kind of water conservation urea fertilizer and preparation method thereof

Technical field

The present invention relates generally to a kind of technical field of fertilizer, particularly a kind of water conservation urea fertilizer and preparation method thereof.

Background technology

China's agricultural planting amount is large, life-time service chemical fertilizer, and chemical fertilizer plays an important role in China's agriculture production as the factor of determination of farming volume increase.At present, China has become maximum in the world chemical fertilizers production state and country of consumption, but life-time service can make soil aggregate be destroyed, easily cause soil compaction, soil property hardening, adopt soil redeposition can make to prevent that soil from weathering, reducing soil water evaporation or excessively transpiration, save irrigation water and promoting the effects such as plant health growth.

Summary of the invention

The present invention aims to provide a kind of water conservation urea fertilizer and preparation method thereof.

The present invention is achieved by the following technical solutions:

The present invention is made by the raw material of following weight part: cow dung 40-50, stalk 30-40, Pericarppium arachidis hypogaeae 20-25, urea 60-70, vinylformic acid 8-14, primary ammonium phosphate 11-16, Potassium Persulphate 0.8-1.2, Sodium Selenite 0.9-1.1, N, N '-methylene-bisacrylamide 0.5-0.8, soil redeposition 10-15, EM microbial inoculum 1-2, water are appropriate.

Soil redeposition is made by the raw material of following weight part: wilkinite 110-120, alcohol ester 12 3-4, nanometer jade powder 3-4, oil foot 9-12, xitix 2-3, xanthan gum 2-3, epoxyoleic acid butyl ester 2-3, Sodium Selenite 4-5, zinc sulfate 8-9, magnesium sulfate 6-7, cuttlefish bone meal 5-6, tuber of stemona 10-12, water are appropriate; Preparation method is ground into powder by the tuber of stemona, adds suitable quantity of water with wilkinite, alcohol ester 12, nanometer jade powder, oil foot, xitix, xanthan gum, is heated to 70-80 ℃, grind 1-2 hour, concentrated, dry, add other remaining component, mix, granulation, obtains.

The preparation method of water conservation urea fertilizer is as follows:

(1) be added to the water together with soil redeposition, cow dung after stalk, peanut hull meal are broken into, high-speed stirring is after 30 minutes, then adds urea, Secondary ammonium phosphate, vinylformic acid to be heated to while stirring urea fusing, cooling standby;

(2) other remaining components are added in above-mentioned material, after stirring, fermentation 14-18 days, after having fermented, drying-granulating.

Beneficial effect of the present invention:

The water retention property of the water-maintaining fertilizer by method gained of the present invention is good, and biological and chemical good stability, simultaneously take natural cow dung as base-material, has retained effective nutritive ingredient of cow dung, has expanded effective utilization of resource, and can significantly reduce costs.The soil redeposition that the present invention adds in addition can effectively improve soil physico-chemical property and soil nutrient status promotes plant to produce active influence for the absorption of nutrient and moisture and to soil microorganisms.

Embodiment

The present invention is made by the raw material of following weight part (kg): cow dung 40-50, stalk 30-40, Pericarppium arachidis hypogaeae 20-25, urea 60-70, vinylformic acid 8-14, primary ammonium phosphate 11-16, Potassium Persulphate 0.8-1.2, Sodium Selenite 0.9-1.1, N, N '-methylene-bisacrylamide 0.5-0.8, soil redeposition 10-15, EM microbial inoculum 1-2, water are appropriate.
