Production process of lignin ammonium sulphonate as plant root growth regulator

Abstract

The invention relates to a production process of lignin ammonium sulphonate as a plant root growth regulator, aiming at the problems that the traditional fertilizer has low utilization ratio, causes hardening on lands and is not beneficial to plant root growth. A formula of an organic fertilizer comprises the following materials in percentage by weight: 40%-70% of added organic raw materials, 30%-45% of straw power generation plant ash, 5%-15% of attapulgites and 2%-6% of lignin ammonium sulphonate, wherein the added organic raw materials contain more than or equal to 60% of organic matters; a formula of an inorganic compound fertilizer comprises the following materials in percentage by weight: 20%-40% of urea, 20%-30% of monoammonium phosphate, 10%-30% of potassium chloride, 2%-6% of ammonium sulfate, 2%-6% of medium trace elements, 5%-15% of attapulgites and 2%-6% of lignin ammonium sulphonate, wherein the content of the potassium chloride is 60%; and a formula of an organic-inorganic compound fertilizer comprises the following materials in percentage by weight: 10%-20% of urea, 10%-20% of monoammonium phosphate, 20%-30% of ammonium chloride, 5%-15% of potassium chloride, 2%-6% of ammonium sulfate and 10%-20% of added organic raw materials with the organic matters of more than or equal to 60%, 2%-6% of medium trace elements, 2%-6% of lignin ammonium sulphonate and 2%-6% of attapulgites. The production process comprises the following steps of: blending various raw materials in a blending disc according to the formulas; and crushing, granulating, dying, screening, cooling and packaging to form fertilizer commodities according to a general production process of producing compound fertilizers.

Description

Technical field: [0001] The invention belongs to the technical field of fertilizer processing, and in particular relates to a production process of using ammonium lignosulfonate as a plant root growth conditioner. Background technique: [0002] According to the World Food and Agriculture Organization survey, about 50% of the increase in world grain production is the result of increasing chemical fertilizers. The rapid growth of population and the intensification of the contradiction between food supply and demand have made agricultural production for the purpose of pursuing crop yield increasingly dependent on chemical fertilizers. In 1995, my country's total fertilizer consumption reached about 36 million tons. In order to meet the growing population's demand for food supply and demand, chemical fertilizer application will still be one of the main measures to increase food production for a long time to come. [0003] In the past 40 years, the amount of chemical fertilizer...
