Abstract

The invention relates to the technical field of a fertilizer, in particular to a silicon fertilizer and the production technique and application thereof. The invention aims at utilizing straw as paper making raw materials to extract elements of silicon, humic acid, fulvic acid, cellulose, carbon, calcium, potassium, boron, magnesium, etc., which are beneficial to crops from waste liquid generated in paper making, and main active ingredients of extractive are utilized, a plurality of accessory ingredients are added, thereby generating a soluble fertilizer with high quality. The fertilizer parts by weight are that: 0.5 to 4 portions of soluble silicon, 0.8 to 6 portions of humic acid, 0.5 to 5 portions of fulvic acid, 0.5 to 4 portions of cellulose, 0.3 to 20 portions of phosphorus, potassium, calcium, boron and magnesium, 0.6 to 3 portions of surface active agent, 0.5 to 2 portions of synergistic agent, 1 to 3 portions of filmerformer, 2 portions of settling agent, 50 to 95 portions of pulverized fuel ash. The invention has the advantages that: raw material cost is not required by utilizing waste liquid of straw paper making as the raw materials; resources are saved, and produced fertilizer comprises a high content of silicon; the fertilizer can be completely absorbed by the crops, pertaining to an environment friendly fertilizer, which brings no secondary pollution to soil. The invention can be widely applied to paddy rice and other gramineous crops, oil crops, cash crops, fruits, sugar cane and grapes, and is endowed with a huge market potential.

Description

technical field [0001] The invention relates to the technical field of a fertilizer, in particular to a silicon fertilizer and its production process and application. Background technique [0002] As an essential nutrient element for crops, the amount of silicon fertilizer is increasing. Selected from the rural practical technology "Overview of the Application of Rice Silicon Fertilizer at Home and Abroad", it is pointed out that the application of silicon fertilizer to silicon-loving crops and silicon-deficient soils in nine provinces including Henan and Shandong has significantly increased the yield of crops: rice 10%-20%, wheat 10% %-15%, peanuts 15%-35%, soybeans 10%-20%, sugarcane 10%-25%, vegetables 10%-20% while improving product quality. Silicon fertilizer can also play a role in disease prevention, such as rice blast, leaf spot, stem rot, rust, etc. The input of 16-20 yuan per mu is only equivalent to 10%-20% of the price of other fertilizers. Reach 1:5-10. my co...
