Abstract
The invention relates to the technical field of slow-release fertilizer, in particular to slow/controlled-release fertilizer containing organic matters. The fertilizer comprises 65-80 parts of urea formaldehyde powder, 10-20 parts of Abamectin dregs and 5-15 parts of rice husk charcoal. Firstly, master batches are prepared from urea formaldehyde powder and 2/3 of Abamectin dregs, then the rest 1/3 Abamectin dregs and rice husk charcoal cover the master batches, and fertilizer granules are prepared. The slow-release fertilizer contains urea formaldehyde powder, Abamectin dregs and rice husk charcoal, is seldom released before 10 days and a little release before 20 days, reaches the high-speed release period after 20 days, still has efficiency after 70 days, is slow-release nitrogen fertilizer with an excellent slow-release effect, can be used for various grain crops, cash crops, vegetables and fruits, and provides richer nutrition for crops due to addition of Abamectin dregs and organic matters.
Description
Technical field
The present invention relates to slow release fertilizer technical field, particularly a kind of endoplasm slow-release or control-release fertilizer, also relate to the preparation method of described endoplasm slow-release or control-release fertilizer.
Background technology
Current agriculture main fertilizer is based on the chemical fertilizer of nitrogenous, phosphorus, potassium, can play the effect of supplementary respective element, have certain effect of increasing production to crop after using.But the utilization ratio of fertilizer is but in low-down level always, a large amount of nitrogen, phosphorus, potassium element, because release is improper for opportunity, can not be effectively utilized by crop and be trapped in soil, and nutritive element waste is serious, and causes environmental pollution.After soil life-time service chemical fertilizer, soil compaction is serious, and organic microbial reduces, even contaminated, causes soil quality to decline, and crop yield declines.
Using slowly/controlled releasing fertilizer is one of effective way alleviating fertile element loss, and the comparable common utilization rate of nitrogen fertilizer of usual slowly/controlled releasing fertilizer improves 10% ~ 30%, reduces rate of fertilizer application 15% ~ 20%.Owing to there is plurality of advantages, slowly/controlled releasing fertilizer has become the focus of fertilizer research in recent years, slowly/controlled releasing fertilizer in China's development rapidly, and achieve certain economic benefit and ecological benefits, compare the method for agronomic measures and biological pathway raising utilization rate of fertilizer, better effects if on raising utilization rate of fertilizer is promoted in the research and development of slowly/controlled releasing fertilizer, has larger advantage.Wherein urea aldehydes slow-release nitrogen fertilizer is developed successfully the earliest, realizes business-like slow release fertilizer at first, but still be the slow release fertilizer that in current world wide, amount of application is maximum, becomes the slow-release nitrogen fertilizer kind received much concern.
But now for organic fertilizer but do not have corresponding inhibition fertilizer or slow releasing function effect poor, and urea-formaldehyde fertilizer lacks natural biomass, cause there are relative merits separately, therefore, studying a kind of inhibition fertilizer containing organic fertilizer, is that in fertilizer field, demand is the most urgent.
Summary of the invention
In order to solve the problem that both that exist in above existing slow release fertilizer and organic fertilizer can not combine very well, this application provides a kind of containing organic and there is the endoplasm slow-release or control-release fertilizer of corrosion mitigating effect.
Present invention also provides the preparation method of described endoplasm slow-release or control-release fertilizer.
The present invention is achieved by the following measures:
A kind of endoplasm slow-release or control-release fertilizer, raw material weight proportioning is as follows:

Urea is soluble in water, pH7.5-8 is regulated by buffer system, add furfural, the mol ratio of urea and furfural is 1.9:1, feeds in raw material while stir, keep temperature of reaction system 50-55 DEG C, insulation 1h, then rises to 70 DEG C by temperature of reaction system, regulation system pH5-5.5, stirring reaction 1h, by product drying and crushing to 100-200 order and get final product.
Described endoplasm slow-release or control-release fertilizer, preferred feedstock weight proportion is as follows:
Urea aldehyde powder 70-75 part, avermectin slag 13-17 part, rice hull carbon 8-12 part.
Described endoplasm slow-release or control-release fertilizer, containing organic more than 75% in preferred avermectin slag.
Described endoplasm slow-release or control-release fertilizer, preferred rice hull carbon particle diameter is 100 orders.
Described endoplasm slow-release or control-release fertilizer, preferred feedstock weight proportion is as follows:
70 parts, urea aldehyde powder, avermectin slag 17 parts, rice hull carbon 8 parts.
Described endoplasm slow-release or control-release fertilizer, preferred feedstock weight proportion is as follows:
75 parts, urea aldehyde powder, avermectin slag 13 parts, rice hull carbon 12 parts.
Described endoplasm slow-release or control-release fertilizer, preferred feedstock weight proportion is as follows:
73 parts, urea aldehyde powder, avermectin slag 15 parts, rice hull carbon 10 parts.
The preparation method of described endoplasm slow-release or control-release fertilizer, first makes master batch by the avermectin slag of urea aldehyde powder and 2/3rds, more remaining 1/3rd avermectin slags and rice hull carbon is wrapped in outside master batch and makes fertiliser granulates.
Described preparation method, preferred master batch particle diameter is 0.8-2mm.
Described preparation method, preferred fertiliser granulates particle diameter is 1-3mm.
Beneficial effect of the present invention:
Containing urea aldehyde powder, avermectin slag, rice hull carbon in the slow-release fertilizer of the application, before 10 days, release seldom, before 20 days, burst size is also little, the high speed pay-out phase is entered after 20 days, still effective after 70 days, be a kind of slow-release nitrogen fertilizer of slow release effect excellence, can use in various food crop and cash crop and veterinary antibiotics, and due to adding of avermectin slag, add organic matter, for crop provides abundanter nutrition.
