Problems solved by technology
The main means of calcium supplementation is the intake of calcium supplementation agents. The main component of calcium tablets currently available on the market is calcium carbonate. According to the results of static in vitro artificial gastrointestinal simulation tests, the bioavailability of calcium in calcium tablets is not high, which is lower than that of high calcium tablets. Calcium plant materials and calcium-rich animal materials, and one of the main causes of calcium deficiency in the elderly is calcium absorption barriers. Therefore, the development of high-calcium materials with higher bioavailability is of great significance to solve the problem of calcium deficiency

[0039] The preparation method of the above-mentioned calcium-enriched nutritional agent comprises the following steps:
[0040] 1) After the calcium source is pulverized, it is then superfinely pulverized into a powder with a particle size of less than 50 μm, and the proportion of nano-scale is 5~20wt%;
[0041] 2) Grind borax, molybdenum sulfide, humic acid and attapulgite powder until the particle size is less than 100 μm, and set aside;
[0042] 3) Mix the calcium source, borax, molybdenum sulfide, humic acid and attapulgite powder obtained according to steps 1) and 2), add fertilizer binder, and granulate on a disc granulator to obtain the product.
[0043] The method for cultivating calcium-enriched black cabbage with the above-mentioned calcium-rich nutrient is as follows: after the black cabbage is transplanted, the calcium-rich nutrient is applied.

Abstract
The invention discloses a calcium-rich nutrient, a preparation method thereof and a method for culturing calcium-rich Chinese flat cabbage. The calcium-rich nutrient is prepared from the following components in parts by mass: 10-20 parts of calcium source, 0.4-2.0 parts of borax, 0.2-1.2 parts of molybdenum sulfide, 0.5-2.5 parts of humic acid, 2-20 parts of attapulgite powder and 0.2-0.8 part of fertilizer binding agent. The preparation method comprises the following steps: smashing the calcium source, performing superfine grinding on the smashed calcium source to obtain powder which is less than 50mum in particle diameter, wherein nano-scale powder accounts for 5-20 percent by weight; smashing the borax, the molybdenum sulfide, the humic acid and the attapulgite powder respectively till the particle diameter is less than 100mum for later use; uniformly mixing the calcium source, the borax, the molybdenum sulfide and the attapulgite powder treated above, adding the fertilizer binding agent, granulesting on a disc granulestor till the particle diameter is 5-10mm. According to the method for culturing the calcium-rich Chinese flat cabbage, the calcium-rich nutrient is added timely after transplanting survival of the Chinese flat cabbage in order to harvest the calcium-rich Chinese flat cabbage finally.
Description
technical field [0001] The invention belongs to the technical field of agricultural fertilizers and agronomy, and in particular relates to a calcium-enriched nutrient, a preparation method thereof and a method for cultivating calcium-enriched black cabbage. Background technique [0002] Calcium is one of the most important elements in the human body. It is an indispensable ion for various physiological activities of the body. It participates in all life activities and maintains the normal physiological functions of cells. It accounts for 1.7~2.1% of the body weight. Most of the physiological activities of the human body are related to calcium, and the balance of calcium metabolism plays a vital role in maintaining life activities. From young children to the elderly, calcium nutrition metabolism imbalance may occur in all age groups of human beings. The research on human calcium nutrition balance has a very important impact on improving human health. Children and the elderly...
