specific Embodiment approach 1

[0013] Specific embodiment one: the preparation method of present embodiment calcium fertilizer, carry out according to the following steps:

[0014] 1. Put the thickener and pure water in a liquid mixer according to the weight ratio (0.2~2):100, and stir at a speed of 500~1000r / min for 10~60min to obtain a colloid;

[0015] 2. According to the weight ratio (0.01-0.05): 100, put the penetrant and nano-scale calcium carbonate in a high-speed mixer, stir at a speed of 1000-3000r / min for 5-10min, then add the adsorbent and continue stirring for 5-10min , to obtain processed calcium carbonate;

[0016] Three, according to weight ratio (10~80): 100 place processed calcium carbonate and colloid in liquid mixer, stir 10~30min with the speed of 500~1000r / min, promptly finish the preparation of calcium fertilizer;

[0017] Wherein the particle size of the nano-scale calcium carbonate in the step 2 is 10-30 nanometers; the weight ratio of the adsorbent to the nano-scale calcium carbona...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment is different from Embodiment 1 in that the thickener in step 1 is one or a mixture of xanthan gum, carrageenan, gum arabic, and guar gum. Other steps and parameters are the same as those in Embodiment 1.

[0021] In this embodiment, when the thickener is a mixture, various substances are mixed in an equal weight ratio.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in Step 1, the thickener and purified water are placed in a liquid mixer at a weight ratio of 1:100. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

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

technical field [0001] The invention relates to a preparation method of calcium fertilizer. Background technique [0002] The calcium fertilizers currently on the market are basically divided into two categories, inorganic calcium fertilizers and organic calcium fertilizers. Inorganic calcium fertilizer is divided into two types: root application and foliage spraying. The main component of root application calcium fertilizer is calcium phosphate, which has a low absorption and utilization rate after use, and long-term use will easily cause soil compaction; the main component of foliar spraying It is calcium chloride or calcium nitrate, but its use is restricted because it contains chloride ions and nitrate ions that are harmful to crops. Most of the organic calcium fertilizers are sprayed on the leaves, and its main component is chelated calcium. Because the effective calcium content is too low and the price is high, its popularization and application are also limited. Co...
