Problems solved by technology

[0004] At present, the calcium fertilizers produced in China mainly include inorganic mixed calcium fertilizer and organic liquid calcium fertilizer. Fixation directly affects the absorption of calcium and the content of calcium in the product; the other is the method of spraying organic liquid calcium fertilizer on the leaves. Although spraying outside the root is the most economical and effective method of fertilization, the calcium agent sprayed is simple. , The formula is single, which is often not conducive to promoting the absorption of calcium, and the utilization rate and safety of calcium sprayed are low

Abstract

The invention provides a calcium-rich organic liquid fertilizer which comprises the following compositions: 20-40% of a chelated calcium solution, 10-30% of a chelated iron solution, 10-20% of a urea solution, and 20-30% of water. The invention further provides a preparation method for the calcium-rich organic liquid fertilizer. According to the calcium-rich organic liquid fertilizer, provided by the invention, the calcium-rich organic liquid fertilizer added with iron and nitrogen is prepared by adopting the preparation method based on certain improvement and aiming at the problems and defects existing in the prior art, the paddy rice yield is greatly improved, the absorption and utilization of calcium and other elements are facilitated, the content of organic calcium in rice is increased, the rice quality is improved, and besides, the calcium-rich organic liquid fertilizer has the advantages of safety, non-pollution, relatively simple preparation method, low cost and the like.

Description

technical field [0001] The invention belongs to the field of organic liquid calcium fertilizer, in particular to a calcium-rich organic liquid fertilizer for rice production and a preparation method thereof. Background technique [0002] Calcium is known as the "life element" of the human body. It is the most abundant inorganic element in the human body, with a total amount of more than 1kg. Calcium is very important to the human body, not only related to bone health, but also may be related to high blood pressure, premenstrual tension syndrome and so on. Calcium ions can maintain the biological potential on both sides of the cell membrane, maintain normal nerve conduction function, maintain normal muscle contraction and relaxation function and nerve-muscle conduction function, and the action mechanism of some hormones are all expressed through calcium ions. [0003] From August to December 2002, led by the Ministry of Health, the Ministry of Science and Technology and the ...
