Abstract
The invention relates to a controlled release agent of a blended fertilizer and a production process thereof, solving the problems of low fertilizer utilization rate and incomplete nutrients of the blended fertilizer. The invention also discloses a controlled release agent containing a water retaining agent. The controlled release agent comprises the following raw components: 5-20 percent of nitrification inhibitor, 10-50 percent of colloid, 0.1-5 percent of trace elements and 10-70 percent of stuffing. The controlled release agent of the blended fertilizer specifically comprises the following components: 15 percent of thiourea, 8 percent of dicyandiamide (DCD), 10 percent of ketopyrrolidine, 25 percent of humic acid (HA), 20 percent of ethyl cellulose, 2 percent of zinc sulphate, 0.5 percent of copper sulfate, 0.4 percent of magnesium sulfate 0.1 percent of ammonium molybdate, 1 percent of borax, 0.8 percent of ferrous sulfate and 17.2 percent of zeolite. The method for producing the controlled release agent of a blended fertilizer comprises the step of: evenly mixing the thiourea, the ethyl cellulose, the HA, the zinc sulphate, the copper sulfate, the ferrous sulfate, the ammonium molybdate, the borax and the zeolite powder in stirring equipment to reach 60-80 mesh powder. The invention can be applied to blended bulk fertilizer and the production thereof and has notable advantages.
Description
(1) technical field: the present invention relates to the slow sustained release additive of a kind of Bulk Blending Fertilizer, belong to the chemical fertilizer technical field.
(2) background technology: there are a lot of problems in the chemical fertilizer that uses at present, as because of using low financial loss that causes of chemical fertilizer and plant recovery of nutrient and environmental pollution etc. in a large number, how significantly improving utilization rate of fertilizer and give full play to the effect of chemical fertilizer, is to continue in the high-efficiency agriculture development one of distinct issues at present.The invention of release and release control fertilizer and production and being applied as on agricultural address this problem new thinking and the more effective approach opened up.
Chemical fertilizer is the valuable cargo of agriculture production, the fertilizer consumption of annual China all reaches about more than 5,000 ten thousand tons (pure), but behind these incorporation of fertilizerin the soil, have greatly to be wasted, such as nitrogenous fertilizer is calculated according to Chinese Academy of Sciences's Nanjing soil, the nitrogenous fertilizer this season utilization ratio of China has only about 35%, have 65% nitrogenous fertilizer to run off in vain, these loss of nitrogenous fertilizer have number of ways, and a kind of is that the effect of the enzyme of nitrogenous fertilizer in soil is converted into NO
3 -And NH
4 +, because soil particle has negative charge, it can not adsorb NO
3 -NO
3 -Very easily be dissolved in the water, so NO
3 -Mobile more intense, its can be along with rainwater, water to pour water etc. and arrived undergroundly by leaching, enters the lake.Cause the eutrophication in lake, also had the NH in the soil
4 +Along with the rising of temperature is converted into NH
3, discharge into the atmosphere.Perhaps NH under the effect of nitrite bacteria
4 +Also can be converted into NO
3 -Lose with current.
(3) summary of the invention: the objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of stimulation crop to absorb nutritive ingredient, prevent the loss of fertilizer, improve fertilizer utilization ratio, prolong fertilizer efficiency period, realize that single fertilization does not topdress, save fertilizer, make the controlled release agent of blended fertilizer of crop yield
Purpose of the present invention can realize by following measure:
Above raw material is carried out thorough mixing at normal temperatures and pressures in proportion, and the back of sieving is even meal.
The present invention can produce following positively effect compared with the prior art: it is low to the present invention is directed to China's chemical fertilizer utilization ratio, reason developments such as phase fertilizer efficiency phase is short, controlled release agent of blended fertilizer is mixed with chemical fertilizer by a certain percentage, execute in the ground then, this controlled release agent of blended fertilizer can suppress the urease activity in the soil and suppress the activity of nitrobacteria, thereby can slow down nitrogenous fertilizer and be converted into the form that can run off, nano level zeolite is poroid material in the compound fertilizer long-acting synergist simultaneously, and it can adsorb NH
4 +, PO
4 3-, HPO
4 2-And K
+, NO
3 -Ion prevents the loss of nitrogenous fertilizer, the loss of the fixing and potash fertilizer of phosphate fertilizer, and contain HA, it is a kind of yield stimulant, can stimulate crop to absorb nutritive ingredient, prevents the loss of fertilizer.HA has the effect that stimulates plant growth, can stimulate the absorption of crop to fertilizer,
This controlled release agent of blended fertilizer has also added the needed trace element of crop simultaneously, can satisfy crop and locate absorption to macroelement, trace elements absorbed in can also increasing.G
This additive also adds the colloid with water retaining function, and this colloid can absorb the moisture volumetric expansion simultaneously in the soil, come accommodating seed to germinate and seedling period to the demand of moisture.
1, the utilization ratio that can improve nitrogenous fertilizer with the present invention reaches 60%-70%, and the fertilizer efficiency period that can make chemical fertilizer with the present invention was brought up to 90-200 days by 35-60 days.
2, can realize that single fertilization does not topdress behind use the present invention.
3, can save fertilizer with the present invention, with the fertilizer that can save 20%-30% under the equal yield line.
4, using the present invention that crop is increased production under the situation of equal rate of fertilizer application on average reaches more than 15%.
5, use the present invention in base manure, need not re-use middle trace element.
6, be suitable for the present invention and can play the effect that water conservation is kept a full stand of seedings.
