Abstract

The invention belongs to the field of fertilizers, and relates to a liquid calcium fertilizeras well as a preparation method and application thereof. The liquid calcium fertilizer is prepared from the following components by weight: 35-59 parts of calcium element, 1-2 parts of a wetting agent, 2-4 parts of a dispersant, 0.5-1 part of a surfactant, 1-3 parts of an emulsifier, 2-3 parts of an antifreezing agent, 0.5-4 parts of a thickener, 0.1-0.2 part of an antifoaming agent, and 27.3-51.8 parts of water. Calcium is suspended together in the form of micro-nano particles through an ultra-micro nano technology and a water-phase micro-suspension polymerization technology, the content of calcium in the obtained ultra-micro nano suspension liquid calcium fertilizer is high and can reach 280-612 g/L, the average particle size of the calcium is about 1.5 microns, the prepared ultra-micro nano suspension liquid calcium fertilizer can improve the dispersing performance of the ultra-micro nano suspension liquid calcium fertilizer in an aqueous solution system, and the calcium nutrition can be well and quickly supplemented for crops.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a liquid calcium fertilizer and its preparation method and application. Background technique [0002] Calcium is one of the medium nutrients necessary for the normal growth and development of plants. It is related to the physiological reactions in plants and the development of cell tissue structure. It plays an important role in the formation and maintenance of fruit quality, especially in the later stage of fruit development. The amount has an important impact on the formation of fruit quality and postharvest storage and transportation. [0003] Calcium is not only an element necessary for the growth and development of crops, but also as a second messenger of extracellular signals and intracellular physiological and biochemical reactions to participate in the regulation of fruit tree growth and development. Calcium deficiency in plants often leads to necrosis of meristema...
