Problems solved by technology

However, usually these products can only provide nitrogen, phosphorus, and potassium, but cannot provide rich organic matter for improving soil and regulating plant growth. During fertigation, farmers will also separately topdress organic fertilizer after retting and multi-stage filtration
Most of the organic-inorganic compound fertilizers on the market have poor solubility and a lot of residue, which can easily block the irrigation and fertigation system

Abstract

The invention relates to a water-soluble high-concentration organic-inorganic compound fertilizer for trickle and sprinkling irrigation and a preparation method thereof, belongs to the technical field of integration of water and fertilizer and high concentration organic-inorganic compound fertilizers. The fertilizer comprises the following components in percentage by weight: 35-70% of urea or 40-70% of modified nitramine, 5-40% of water-soluble phosphatic fertilizer, 0-35% of water-soluble potassic fertilizer, 20-40% of water-soluble organic matters, 0.05-0.1% of a water-soluble fertilizer synergist, 0.1-10% of water-soluble chelating medium trace elements and 0.1-10% of a plant growth adjustor. Nitrogen, phosphorus and potassium account for 30-50% of the prepared water-soluble high-concentration organic-inorganic compound fertilizer for trickle and sprinkling irrigation and the organic matters account for 15-25% of the prepared water-soluble high-concentration organic-inorganic compound fertilizer for trickle and sprinkling irrigation. The water-soluble high-concentration organic-inorganic compound fertilizer is good in solubility, can be matched with trickle and sprinkling irrigation equipment and achieves integration of water and fertilizer; the utilization ratios of nitrogen, phosphorus and potassium and trace elements are high, and the fertilizer has the advantages of improving the soil environment, adjusting crop growth, enhancing stress resistance of the crop, and improving the quality of crops.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer and a preparation method thereof, in particular to a water-soluble high-concentration organic-inorganic compound fertilizer for drip irrigation and a preparation method thereof, which belongs to the technology of water-fertilizer integration and high-concentration organic-inorganic compound fertilizer field. Background technique [0002] Water and fertilizer integration technology refers to the comprehensive regulation and integrated management of water and nutrients in farmland, using fertilizer to transfer water, using water to promote fertilizer, and comprehensively improving the efficiency of water and fertilizer use, including application modes such as flushing, showering, sprinkler irrigation, and drip irrigation. Low-level methods such as flushing and showering use a lot of water, and the utilization rate of water and fertilizer is low. The unused fertilizer penetrates into the so...
