preparation example Construction

[0024] The preparation method of the above-mentioned silicon-containing fertilizer is based on the production process of urea, and the urea production system can be slightly modified. In the past, the urea production system included a urea synthesis system, a urea evaporation system and a urea granulation system in series. The specific process of the above-mentioned urea production system for the preparation of silicon-containing fertilizers is as follows:

[0025] 1) the NH 3 and CO 2 Input in proportion to the urea synthesis system for synthesis to obtain urea aqueous solution;

[0026] 2) Prepare a silicic acid aqueous solution with a mass concentration of 60% to 80%, and add it to the above-mentioned urea aqueous solution in proportion to obtain a silicon-containing urea aqueous solution;

[0027] 3) Inputting the silicon-containing urea aqueous solution into the urea evaporation system for evaporation to obtain silicon-containing urine;

[0028] 4) After the synergist ...

Embodiment 1

[0050] The silicon-containing fertilizers in Examples 1 to 3 were respectively carried out in Liaozhong, Panjin, Huludao and other places for large-scale demonstration tests. The results showed that the crop areas where the above-mentioned silicon-containing fertilizers were used as base fertilizers showed lodging resistance, disease and insect resistance, etc. Stress resistance, can improve crop quality, wherein, the fertilizer in embodiment 1 can increase yield 20~25%, the fertilizer in embodiment 2 and embodiment 3 can improve yield 15~20%, and test observation uses above-mentioned silicon-containing After fertilization, the soil structure is significantly improved and the nutrient content of the soil is increased.

Abstract

The invention discloses a silicon-containing fertilizer and a preparation method and application thereof. The silicon-containing fertilizer is prepared from the following ingredients in parts by weight: 3-5% of silicon, 0.05-2% of synergist and the balance of urea. The preparation method for the silicon-containing fertilizer comprises the following steps: inputting NH3 and CO2 into a urea synthesis system at a ratio to be synthesized so as to obtain urea aqueous solution; preparing silicic acid aqueous solution of which the mass concentration is 60-80%, adding into the urea aqueous solution ata ratio to obtain silicon-containing urea aqueous solution; inputting the silicon-containing urea aqueous solution into a urea evaporation system to be evaporated to obtain silicon-containing urine;dissolving the synergist into the silicon-containing urine at a ratio, and carrying out granulation on a urea granulation system to obtain a finished product. The silicon-contained fertilizer can be used as base fertilizer and additional fertilizer or can be used as a nitrogen source to be prepared into blended fertilizer.

Description

technical field [0001] The disclosure of the invention relates to the technical field of fertilizers, in particular to a silicon-containing fertilizer and its preparation method and application. Background technique [0002] Silicon fertilizer is a good quality fertilizer, health fertilizer and plant regulating fertilizer, and it is a new type of multifunctional fertilizer that other chemical fertilizers cannot match. Silicon fertilizer can be used not only as a fertilizer to provide nutrients, but also as a soil conditioner to improve the soil. In addition, silicon fertilizer also has the functions of disease prevention, insect prevention and attenuation. Silicon fertilizer will become an efficient and high-quality fertilizer for the development of green ecological agriculture due to its outstanding advantages such as non-toxic, tasteless, no deterioration, no loss, and no pollution. [0003] At present, there are two main forms of silicon fertilizer; one is soluble solid...
