Abstract

The invention relates to a preparation method for a calcium fertilizer. The preparation method provided by the invention solves the problem that inorganic calcium fertilizers at present are low in rate of absorption and utilization, will harden soil if being used for a long time and contain toxic and harmful ions while organic calcium fertilizers are too low in effective calcium content and high in price. The preparation method comprises the steps: I, mixing a thickener with pure water to obtain a colloid; II, mixing a penetrant, nanoscale calcium carbonate and an adsorbent to obtain treated calcium carbonate; and III, mixing the treated calcium carbonate with the colloid to prepare the calcium fertilizer. The calcium fertilizer provided by the invention is the liquid calcium fertilizer which is free of any toxic and harmful ions, high in effective calcium content and good in adsorption effect of crops, and does not harden soil if being used for a long time. The raw and auxiliary materials for preparing the calcium fertilizer are non-toxic and harmless and green and environmental-friendly, so that a green agricultural planting requirement is met; a product is low and reasonable in price; the calcium fertilizer provided by the invention is simple and convenient in preparation method, free of high temperature and high pressure and free of three waste discharge in the production process, and belongs to an environmental-friendly product.

Description

A kind of preparation method of calcareous fertilisers
Technical field
The present invention relates to a kind of preparation method of calcareous fertilisers.
Background technology
The calcareous fertilisers sold in the market are divided into two large classes substantially, inorganic calcareous fertilisers and organic calcium fertilizer.Inorganic calcareous fertilisers are divided into again Gen Shi and foliage spray two class, and the main component that root executes calcareous fertilisers is mainly calcium phosphate, and it uses rear absorption rate very low, cuts life-time service and easily causes soil compaction; The main component of foliage spray is calcium chloride or nitrocalcite, due to containing to the disadvantageous chlorion of crop, nitrate ion, makes it use and is restricted.Organic calcium fertilizer mostly is foliage spray, and its main component is chelating calcium, because the active calcium ion content is too low and expensive, applies and is also restricted.
Summary of the invention
The present invention seeks to solve current inorganic calcareous fertilisers absorption rate low, long-time use can be hardened soil, and containing poisonous harmful ion, and organic calcium fertilizer exists the too low and expensive problem of the active calcium ion content, and provides a kind of preparation method of calcareous fertilisers.
A preparation method for calcareous fertilisers, carries out according to the following steps:
One, by weight (0.2 ~ 2): thickening material and pure water are placed in liquid stirrers by 100, stir 10 ~ 60min with the speed of 500 ~ 1000r/min, obtain colloid;
Two, by weight (0.01 ~ 0.05): permeate agent and nanometer grade calcium carbonate are placed in high speed mixer by 100,5 ~ 10min is stirred with the speed of 1000 ~ 3000r/min, then add sorbent material and continue stirring 5 ~ 10min, obtain the rear calcium carbonate of process;
Three, by weight (10 ~ 80): calcium carbonate after process and colloid are placed in liquid stirrers by 100, stir 10 ~ 30min, namely complete the preparation of calcareous fertilisers with the speed of 500 ~ 1000r/min;
Wherein in step 2, the grain size of nanometer grade calcium carbonate is 10 ~ 30 nanometers; The weight ratio of step 2 sorbent material and nanometer grade calcium carbonate is (0.05 ~ 1): 100.
The raw and auxiliary material that the present invention prepares calcareous fertilisers is all nontoxic, and environmental protection meets green agriculture planting requirement; The raw and auxiliary material market of preparing calcareous fertilisers is easy to get and cheap, and cost is low, and thus goods low price is reasonable; Preparation method's science of calcareous fertilisers of the present invention is easy, and without the need to High Temperature High Pressure, three-waste free discharge in production process, belongs to environmentally friendly product.
The present invention prepares gained calcareous fertilisers, is aqueous calcareous fertilisers, and not containing any poisonous and harmful ion, the active calcium ion content is high, and Crop is effective, and uses the soil that can not harden for a long time.
The present invention prepares gained calcareous fertilisers, using method is flexible, allly need calcium crop all can use, can foliage spray also can drip irrigation give fertile, and can use with other foliage fertilizer and mixed pesticide, spray cost for user saves, can also with fungicide compounding for preventing the generation of crop pest, improve output, remarkable in economical benefits.
