Embodiment 1

[0036] A foliar fertilizer for preventing and treating manganese poisoning in sugarcane, comprising a first material and a second material, the mass ratio of the first material to the second material is 2.5:1; wherein, the first material includes the following raw materials 3 kilograms of sodium metasilicate, 1.5 kilograms of urea, 10 kilograms of water; the second material includes the third material and the fourth material of equal weight; the third material includes: 150 grams of sodium silicate, 50000 grams of water , 2000 grams of alcohol and 7.5 grams of trimethylammonium bromide; the fourth material includes ferrous sulfate heptahydrate, citric acid, sulfuric acid and water, and the ferrous sulfate heptahydrate and citric acid in the fourth material , The weight ratio of sulfuric acid to water is 5:1:1:30. Described sulfuric acid is sulfuric acid solution (solute is water), and the concentration of sulfuric acid solution is 10mol / L.

Abstract

The invention relates to the technical field of agricultural production, and particularly discloses a silicon-containing composition, a foliar fertilizer for preventing and treating manganese toxicityof sugarcane, a preparation method and an application. The silicon-containing composition comprises the following raw materials: sodium silicate, water, alcohol, trimethyl ammonium bromide, ferrous sulfate heptahydrate, citric acid, sulfuric acid, sodium metasilicate and urea. The silicon-containing composition provided by the invention has a very remarkable effect of overcoming the manganese toxicity of sugarcane seedlings; through reasonable compatibility of various raw materials, the prepared silicon-containing composition can be used as a foliar fertilizer, the manganese content of sugarcane seedlings can be reduced, the manganese toxicity symptom of sugarcane is rapidly reduced, the yellowing rate of seedlings is reduced; meanwhile, the number of sugarcane seedlings and the survivalrate of manganese toxicity sugarcane seedlings are increased, and the yield of sugarcane stems is remarkably increased. The preparation method provided by the invention is suitable for industrial production, and solves the problem that no foliar fertilizer is sprayed to prevent and treat manganese toxicity of sugarcane in the existing method for preventing and treating manganese toxicity of plants.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a silicon-containing composition, a foliar fertilizer for preventing and controlling sugarcane manganese poisoning, a preparation method and an application. Background technique [0002] With the continuous development of agricultural production technology, in the process of plant growth and development, it is usually necessary to apply fertilizers to allow plants to absorb various nutrients necessary to improve the growth and development of plants. Among them, manganese, as an important nutrient element, usually exists in the form of minerals in soil. However, if plants absorb too much manganese, manganese toxicity will occur, and then physiological metabolic disorders and poisoning phenomena such as growth and development will be hindered. Especially for strong acidic soil and poorly drained soil, manganese poisoning is easy to occur, and long-term large-scale ...
