Abstract

The invention discloses a preparation method of a bioactive polypeptide calcium fertilizer, belonging to the field of fertilizer preparation. The preparation method comprises the following steps: adding certain amounts of calcium oxide and manganese oxide into a polysuccinimide suspension, and carrying out hydrolysis reaction to obtain a bioactive polypeptide calcium suspension; adding acid into the polypeptide calcium suspension to regulate the pH value to 5-8, thereby obtaining a bioactive polypeptide calcium clear solution; and adding the bioactive polypeptide calcium clear solution into a fertilizer to obtain the bioactive polypeptide calcium fertilizer. According to the preparation method, the calcium oxide used as a calcium source contacts water in the water solution system to release heat, thereby being beneficial to increase of the reaction rate; and by introducing manganese ions into the polypeptide calcium fertilizer, the calcium and manganese ions are chelated by the peptide bond and carboxyl group on the main chain to generate a stable five-element ring, thereby endowing the polypeptide calcium with bioactivity, greatly postponing the aging of plants due to the bioactivity on the premise of supplementing calcium to the plants, and having obvious yield increase effect.

Description

technical field [0001] The invention belongs to the field of fertilizer preparation, and in particular relates to a preparation method of bioactive polypeptide calcium fertilizer. Background technique [0002] With the development of reform and opening up, agriculture has achieved continuous high yields for many years under the extensive use of various chemical fertilizers (urea, compound fertilizers, etc.), ensuring the stability of my country's grain. However, with the successive years of high agricultural yields, various metal elements in the soil have been consumed in large quantities, resulting in the degradation of soil fertility, especially the lack of calcium, which has seriously threatened my country's food security. [0003] At present, the agricultural calcium supplements in the market are mainly inorganic calcium such as calcium hydroxide and calcium oxide. Although inorganic calcium is cheap, its effect is poor, it is difficult for plants to absorb, and long-te...
