Abstract

The invention provides a macroelement water-soluble fertilizer which comprises the following components in parts by weight: 30-40 parts of urea, 20-30 parts of monopotassium phosphate, 4-6 parts of chelated trace elements, 1-3 parts of amino acid, 3-5 parts of a penetrant and 15-20 parts of a film-forming agent, and the film-forming agent comprises vegetable protein, sodium alginate and carboxymethyl chitosan. The macroelement water-soluble fertilizer prepared by the invention has the effects of preventing rain wash and promoting plant growth.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a large-element water-soluble fertilizer. Background technique [0002] A large amount of water-soluble fertilizer is a multi-element water-soluble fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by plants, and its absorption and utilization rate is relatively high. Soil cultivation, soaking seeds and dipping roots, etc. When a large amount of water-soluble fertilizer is used as a foliar fertilizer, it should not rain within 3-4 hours after spraying the foliage. If it rains, the nutrients are easily washed away by the rain, and it needs to be re-sprayed after the rain stops, which will cause fertilizer and Human waste. In the prior art, a binder is often added to increase the viscosity of the foliar fertilizer so that it can better adhere to the plant surface and reduce rain erosion. However, t...
