Abstract

The invention discloses a preparation method of calcium fertilizer specially used in apple tree germination period, and belongs to the field of fertilizer preparation. The preparation method comprises following steps: certain amounts of calcium oxide and manganese oxide are added into a polysuccinimide suspension solution for hydrolysis so as to obtain a polypeptide calcium suspension liquid with biological activity; an acid is added into the polypeptide calcium suspension liquid so as to adjust pH value to 5 to 8 and obtain a polypeptide calcium clarified solution with biological activity; and the polypeptide calcium clarified solution is added into a fertilizer so as to obtain the calcium fertilizer specially used in apple tree germination period. According to the preparation method, calcium oxide is taken as a calcium source, and contact of calcium oxide with water in an aqueous solution is capable of releasing heat energy, and increasing reaction speed; manganese ions are introduced into the polypeptide calcium fertilizer, so that chelating of calcium and manganese ions by peptide bonds and carboxyl on main chains is realized, stable five-membered rings are generated, and polypeptide calcium is provided with biological activity; in calcium supply of plants, the biological activity is capable of delaying aging of plants greatly, and yield is increased greatly.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of fertilizer preparation, and in particular relates to a method for preparing a special calcium fertilizer for the germination stage of apple trees. [0003] 【Background technique】 [0004] Calcium supplements for apple trees are mainly calcium hydroxide, calcium oxide and other inorganic calcium in the market. Although inorganic calcium is cheap, its effect is poor, it is difficult for plants to absorb, and long-term application causes soil pH to increase. A large amount of inorganic calcium is lost with water and soil, enriched in rivers and lakes, causing pollution. Therefore, there is an urgent need in the market for a special calcium fertilizer for the germination period that is easy to absorb, good in effect, and does not pollute the soil. [0005] This calcium fertilizer is a kind of bioactive calcium. Bioactive calcium refers to organic calcium derived from biology. It is pure natural rather than ar...
