Abstract
The invention provides a coating agent chemical fertilizer which is prepared from the following materials in parts by weight: 1 part of a coating agent, 500-900 parts of chemical fertilizer particles and 20-60 parts of a film-forming agent. The invention further provides a preparation method of the coating agent chemical fertilizer. The preparation method comprises the steps of heating the coating agent to 150-200 DEG C, and spraying the coating agent to the chemical fertilizer particles; 2, uniformly mixing the sprayed chemical fertilizer particles with the film-forming agent; 3, cooling, screening and packaging. According to the method, the obtained coating agent chemical fertilizer can be released in a controlled slow manner and has the effect of preventing disease and pest damage.
Description
Technical field
The present invention relates to agricultural fertilizer production technical field, particularly a kind of Drug coating chemical fertilizer and production method.
Background technology
For agriculture production, fertilising and dispenser are essential links, difference and insect pest phase due to vegetative period in the first phase growth of crop are different, fertilising often will be carried out repeatedly with dispenser, but the fertilizer of executing or medicine are all not absorbed by crops, and some impact due to environment is volatilized or runs off, and has caused the waste of resource, also indirectly make production cost improve, and repeatedly fertilising topdress spoiled soil contaminate environment not only return farm crop cause a large amount of diseases and serious agriculture residual.
In addition, domestic except carrying out mechanization production in some large-scale production farms, other are much produced in semi-mechanization in addition, in these areas, farm crop produce the income that can not meet family completely, a lot of people do manual work outside, management for farm crop in field can only be the control that just can do some fertilizer and debug evil in sowing, thisly can not meet the management crop mode that various vegetative period, fertilizer appended and tend to make the output of crop greatly to decline, and fertilising and dispenser can not once complete, peasant's workload and working time have so greatly been increased, therefore produce a kind of controlled, the medicine of slowly-releasing, fertile integrated fertilizer becomes inevitable.
The present invention proposes a kind of Drug coating chemical fertilizer, this chemical fertilizer can have the effect of controlled release, slowly-releasing, in the process of season plant growth, only need to use one time fertilizer, without again topdressing, but also can play pest-resistant effect, to various pests such as the mole cricket of damage to crops, grub, wireworm, cutworms, all can play control action kou.
Summary of the invention
The invention provides a kind of Drug coating chemical fertilizer, can meet the effect of control, slowly-releasing and the prevention and elimination of disease and pests of fertilizer simultaneously.
Technical scheme of the present invention is achieved in that
A Drug coating chemical fertilizer, is made by the material that comprises following weight parts: 1 part of Drug coating, 500～900 parts of chemical fertilizer granules, 20～60 parts of membrane-forming agents.
As further technical scheme, described Drug coating chemical fertilizer is made by the material that comprises following weight parts: 1 part of Drug coating, 800 parts of chemical fertilizer granules, 40 parts of membrane-forming agents.
As further technical scheme, described Drug coating chemical fertilizer also comprises 10～20 parts of anti-caking agent.
As further technical scheme, described Drug coating is alphacypermethrin suspension agent.
As further technical scheme, described chemical fertilizer granule is compound fertilizer granule.
As further technical scheme, described Drug coating chemical fertilizers production method, by following steps, made:
Step 1: Drug coating is heated to 150～200 ℃, and is sprayed chemical fertilizer granule;
Step 2: add membrane-forming agent to mix the chemical fertilizer granule after spray;
Step 3: cooling, screening, packs and get final product.
As further technical scheme, described screening is to sieve out the particle that particle diameter is 2.8～4.0mm.
As further technical scheme, in described step 2, before adding membrane-forming agent, first add anti-caking agent to mix.
Beneficial effect of the present invention and design:
A kind of Drug coating chemical fertilizer that the present invention proposes not only can play the effect of control, slowly-releasing, can also prevent and treat the disease and pest of crop, can greatly reduce farming time and labour intensity; Design for by thering is insect protected, the Drug coating of controlling worm effect is wrapped in the surface of chemical fertilizer granule in the mode of spray, add again afterwards membrane-forming agent, adding the chemical fertilizer granule outside of Drug coating to form a film with controlled release, slow releasing function, at this fertilizer, apply behind soil, the film that outermost layer plays controlled release, slowly-releasing can make Drug coating and chemical fertilizer in film be discharged slowly, and then can make one season crop only use fertilizer one time, and can use no longer in addition pesticide, and then greatly reduce farming time and labour intensity; Another embodiment of the invention is before adding membrane-forming agent, first to add anti-caking agent, then adds membrane-forming agent, can prevent from directly adding membrane-forming agent adhesion, can facilitate follow-up screening work.
