Abstract

The invention discloses a preparation method of a special calcium fertilizer for a germination period of an apple tree, and belongs to the field of fertilizer preparation. The preparation method comprises the following steps: adding quantitative amounts of calcium oxide and manganese oxide into a suspension of polysuccinimide, and performing a hydrolysis reaction to obtain a polypeptide calcium suspension with bioactivity; adding acid into the polypeptide calcium suspension, adjusting pH to 5-8 to obtain clarified polypeptide calcium solution with bioactivity; adding the clarified polypeptide calcium solution into a fertilizer to obtain the special calcium fertilizer for the germination period of the apple tree. According to the preparation method of the special calcium fertilizer for the germination period of the apple tree, the calcium oxide is used as a calcium source, and the calcium oxide encounters water in an aqueous solution system to release heat, so that increase in the reaction speed rate is facilitated; manganese ions are introduced onto a polypeptide calcium fertilizer, and calcium and manganese ions are chelated by peptide bonds and carboxyl groups on a main chain to produce a stable five-membered ring, so that the polypeptide calcium is endowed with bioactivity, and the bioactivity greatly delays aging of a plant while the plant is supplemented with calcium so as to play a significant yield-increasing effect.

Description

【Technical field】 [0001] 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. 【Background technique】 [0002] 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. [0003] This calcium fertilizer is a kind of bioactive calcium. Bioactive calcium refers to organic calcium derived from biology. It is pure natural rather than artificially synt...
