Instant chelated solid water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses instant chelated solid water-soluble fertilizer and a preparation method thereof and belongs to the technical field of fertilizer. The fertilizer is prepared from the followingcomponents: 50 to 80 parts of urea, 10 to 20 parts of potassium sulfate, 1 to 10 parts of manganese sulfate, 1 to 10 parts of ammonium molybdate, 3 to 5 parts of boric acid, 20 to 40 parts of fermented lyophilized powder, 20 to 40 parts of potassium dihydrogen phosphate, 1 to 10 parts of sodium carboxymethyl cellulose, 1 to 5 parts of garlic polysaccharide, 5 to 10 parts of a chelating agent, 5 to 10 parts of an anti-caking agent and 1 to 4 parts of a synergist. According to the instant chelated solid water-soluble fertilizer disclosed by the invention, the anti-caking agent, the chelating agent and the synergist are added and have a common effect with other nutrients; all the nutrients have no antagonistic effect and balanced supplementation of various nutrient elements needed by tomatoes is realized; the fertilizer can be rapidly dissolved and balanced absorption of plants on the nutrients is promoted; the instant chelated solid water-soluble fertilizer has a remarkable production and yield increasing effect on the tomatoes.

Description

technical field [0001] The invention relates to a water-soluble fertilizer, in particular to an instant chelating solid water-soluble fertilizer and a preparation method thereof. Background technique [0002] Tomato is also known as tomato and foreign persimmon. The fruit is rich in nutrition and has a special flavor. It can be eaten raw, cooked, processed into tomato sauce, juice or canned as a whole fruit. Tomato is one of the most widely cultivated fruit vegetables in the world. The United States, the Soviet Union, Italy and China are the main producing countries. In countries in Europe and America, China and Japan, there are large-scale greenhouses, plastic greenhouses and other protected facilities for cultivation. It is widely planted all over China, and the cultivated area is still expanding. At present, due to the single type of fertilizer and unreasonable farming system, the nutrient elements in the soil and crops are extremely unbalanced, which has seriously l...

Problems solved by technology

However, there are still a series of problems in the product quality and manufacturing process of existing water-soluble fertilizers, such as: (1) There are many types of water-soluble fertilizers on the market, but most of them are single large, medium or trace element compounds, which are not targeted and nutritious. It is not comprehensive enough, and there is no special water-soluble fertilizer for tomatoes; (2) The fertilizer elements are all in an ionic state, and the nutrients are easy to antagonize, and the utilization rate of nutrients is low; (3) The product is prone to moisture absorption and caking, especially during processing. Caking is more likely to occur during storage and transportation; (4) Most solid water-soluble fertilizers have low active ingredient content, low plant utilization rate, and easy to pollute the environment, and there are more insoluble substances, and the dissolution rate is slow, which is easy to block nozzles and drip irrigation pipeline

These greatly limit the field application of water-soluble fertilizers
