Abstract

The invention discloses a preparation method of a special calcium fertilizer for kiwi fruit planting and belongs to the field of fertilizer preparation. The method comprises the following steps of adding quantitative calcium oxide and manganese oxide to a suspension of polysuccinimide and carrying out hydrolysis reaction to obtain a polypeptide calcium turbid liquid with biological activity; adding an acid to the polypeptide calcium turbid liquid and adjusting the pH to be 5-8 to obtain a polypeptide calcium clear liquid with the biological activity; and adding the polypeptide calcium clear liquid to the fertilizer to obtain the special calcium fertilizer for kiwi fruit planting. According to the preparation method of the special calcium fertilizer for kiwi fruit planting, calcium oxide is adopted as a calcium source and the calcium oxide releases heat when in water in a water solution system, so that acceleration of the reaction rate is facilitated; and a manganese ion is introduced to the polypeptide calcium fertilizer, a calcium ion and the manganese ion are chelated by a peptide bond on a main chain and carboxyl to generate a stable five-membered ring, so that the polypeptide calcium is endowed with the biological activity; ageing of a plant is greatly delayed by the biological activity while the plant is supplemented with the calcium; and the special calcium fertilizer plays a significant yield-increasing role.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of fertilizer preparation, and in particular relates to a method for preparing calcium fertilizer special for kiwi fruit planting. [0003] 【Background technique】 [0004] At present, calcium hydroxide, calcium oxide and other inorganic calcium are mainly used as calcium supplements for kiwifruit trees 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 th...
