Silicon fertilizer containing amino acids for retaining water and loosening soil and preparation method thereof

Abstract

The invention relates to a silicon fertilizer containing amino acids for retaining water and loosening soil and a preparation method thereof, and the silicon fertilizer is prepared by the following raw materials: 65%-85% of bentonite containing 25%-35% of silicon dioxide and 15%-35% of amino powder of amino acids containing 20%-40% of amino acids. The preparation method of the silicon fertilizer containing the amino acids for retaining water and loosening soil comprises the following steps: weighing the bentonite and the amino acid powder by weight, smashing the bentonite to 90-110 meshes, then mixing the two to lead the pH value to 3.5-8.0 and preparing the amino acid silicon fertilizer with 20%-30% of silicon dioxide, 5%-8% of amino acids and fineness of 90-110 meshes. The amino acids can enhance the absorption role of SiO2 in the bentonite to other substances and promote plant growth, and the bentonite can retain the water absorbed by the amino acids and lead the water absorbed by the amino acids to be difficult to lose, so that the bentonite and the amino acid powder can react mutually, the water-retaining role achieves the best state, and the silicon fertilizer is conductive to enhancing the resistance of crops to pests and diseases, thereby improving the seed-setting rate and simultaneously realizing the roles of retaining water, loosening the soil and preventing compaction.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a silicon fertilizer containing amino acid and a preparation method of the fertilizer. Background technique [0002] Silicon fertilizer is a slightly alkaline or neutral mineral fertilizer containing active silicon. Silicon is an indispensable medium element for plant growth, and its role is second only to nitrogen, phosphorus, and potassium, ranking fourth. Silicon fertilizer is beneficial to improve the photosynthesis of crops, enhance the resistance of crops to diseases and insect pests, improve the lodging resistance of crops by about 80%, prevent the rot and premature aging of crop root systems, and improve the stress resistance of crops, such as drought resistance, dry hot wind resistance, and Low temperature, etc., enhance pollen vigor and activate phosphorus in the soil, thereby increasing the seed setting rate. At present, silicon fertilizer is mainly...

Problems solved by technology

The invention title applied by Nippon Steel Co., Ltd. is "Silicon Fertilizer and Its Manufacturing Method", the announcement number is CN1195709C, and the announcement date is April 6, 2005. It discloses a silicon fertilizer made from slag, which can improve crop yield. Lodging resistance, pest resistance, drought resistance, promotion of photosynthesis, promotion of root growth and development, promotion of effective use of soil nutrients, but because most of the silicon is CaSiO 3 Exist, it is difficult to dissolve in water, the fertilizer effect is slow, CaSiO 3 CaCO is formed after decomposition in the soil 3 It is easy to cause soil compaction, and the manufacturing process of the present invention is complicated and the cost is high

Another kind is to be raw material with water glass, as the title of invention " production method of high-efficiency silicon chemical fertilizer " that applicant Nanjing Agricultural University applied for, patent announcement number CN1021042C, announcement date on June 2, 1993, is to be a kind of water glass as The raw material is separated from water by high-speed centrifugation, and the spray is dried by hot air. In the manufacturing process, the main component is a mixture of anhydrous sodium perdisilicate and sodium metasilicate. However, due to the high production cost and complicated production process of water glass, it has not been widely used.
