Process for producing plant root growth regulator by cow dropping

Abstract

The invention provides a process for producing a plant root growth regulator by cow dropping, belongs to the technical field of fertilizer processing and application, and aims to solve the technical problems that: the production for maturing cow dropping by bacteria needs long time and more areas, the fertilizer has small effect to plant root growth, the utilization rates of nitrogen, phosphor and kalium in the fertilizer are low, more than 50 percent of nutrient flows into a river along with rainwater to form eutrophication, the water body is polluted, and coal and phosphate ore are wasted. The technical scheme adopted by the process comprises the following steps: uniformly mixing the cow dropping and ammonium sulfite; adding nitrogen to adjust the PH value of the mixture; and allowing a sulfonation reaction at a certain temperature to change the physicochemical property of lignin compounds in the mixture. The plant root growth regulator promotes plant root growth when being added into a fertilizer. The plant root growth regulator has the main usage that: when being used in the fertilizer, ammonium lignosulfonate promotes the plant root growth, and improves the utilization rate of nitrogen, phosphor and kalium through a developed root system, so that the fertilizing usage is reduced, the coal and phosphate ore resources are saved, pollution of nitrogen, phosphor and kalium which are lost along with water to pollute the water body environment is reduced, and the additional value of the cow dropping is improved.

Description

Technical Field: [0001] The technology belongs to the field of agricultural fertilizer processing and application. Ammonium sulfite is used to sulfonate lignin in cow manure, change its physical and chemical properties, and add it to fertilizer to promote the growth of plant roots. Background technique: [0002] At present, the utilization rate of ammonia nitrogen of inorganic fertilizers in the market is about 30%, the utilization rate of phosphorus is 15-20%, and more than 50% will cause pollution when water flows into rivers, and waste coal and phosphate resources. The cow dung on the market is uniformly mixed by adding micro-bacteria to the cow dung, adjusting its carbon, nitrogen ratio and moisture, and using the mature rot process to produce organic fertilizer. The mature time takes 25 to 30 days in winter and 15 to 25 days in summer. , The time period is long, the efficiency is low, and the site area is large; the fertilizer produced can improve the soil, but has little ef...
