Water-retaining fertilizer and production method thereof

Abstract

The invention discloses water-retaining fertilizer and a production method of the water-retaining fertilizer. The water-retaining fertilizer is composed of bio-organic fertilizer, water-retenting agent, potassium sulfate, ammonium bicarbonate and calcium superphosphate. According to the main production process, drum skin, corn, grass carbon and cattle and sheep dung are firstly mixed, after the drum skin, the corn, the grass carbon and the cattle and sheep dung are evenly stirred, a composite micro-ecology microbial agent is introduced in the drum skin, the corn, the grass carbon and the cattle and sheep dung, then, warm water is added for adjusting humidity, and anaerobic fermentation is performed in a closed environment to form bio-organic fertilizer; the drum skin, the corn, the grass carbon and the cattle and sheep dung are sequentially added into a stirrer to be stirred, and finished products are formed through granulation, drying, screening, measuring and packaging. The production method is simple in technology and reasonable in component ratio. After the water-retaining fertilizer is used, the problems that because the use amount of the water-retaining agent is small, the water-retaining agent is difficult to apply, and application is uneven are solved, the functions of the fertilizer are fully played, and the yield of crops is increased. The water-retaining fertilizer can serve as fertilizer for farmland water-conserving ancillary facilities having been implemented and base fertilizer for crops in western arid areas, vegetable greenhouses and forest planting plants.

Description

technical field [0001] The invention relates to a fertilizer and a production method thereof, in particular to a fertilizer and a production method thereof, which have the functions of water retention, fertilizer retention, ground temperature regulation and soil improvement, and can effectively increase the yield of agricultural products. Background technique [0002] Agriculture is a major contributor to water use, water scarcity and water conservation. According to statistics, the annual agricultural water consumption accounts for more than 70% of the country's total water consumption, of which 90% is irrigation water. On the one hand, the country's annual agricultural irrigation water shortage is 30 billion m 3 On the other hand, due to the traditional method of flooding irrigation in the national agriculture, the utilization rate of water is as low as 40-45%, and more than 2,000 m of water is lost or volatilized in vain. 3 water. In addition, in the western part of ...
