Problems solved by technology

[0004] Traditional topdressing only topdresses nitrogen fertilizers such as urea, which can easily lead to low fertilizer utilization efficiency and environmental pollution; crops are greedy for greenery and late maturity, stalks are fragile and easy to lodging, and the ability to resist stress is reduced.

Abstract

The invention discloses multielement topdressing fertilizer containing amino acid. The multielement topdressing fertilizer comprises main raw materials and plant nutrition synergistic agents composed of polyglutamic acid and compound sodium nitrophenolate. The main raw materials comprise, by mass, 8%-15% of potassium chloride, 8%-14% of ammonium sulfate, 25%-35% of powdery urea, 2%-6% of amino acid, 0.5%-1.6% of heptahydrate, 35%-45% of ammonium chloride and 3%-8% of macromolecule bonding agents. According to the multielement topdressing fertilizer containing the amino acid, a scientific formula is adopted according to the law that crops need much nitrogen and potassium fertilizer in the topdressing period, the amino acid, medium trace elements and other nutritious substance are added, the root systems of the crops can be promoted to be developed, stalks are made thick and strong, the ability of adversity tolerance is remarkably improved, and the multielement topdressing fertilizer is the preferred fertilizer for producing green agricultural products. The invention further provides a preparing method of the topdressing fertilizer.

Description

technical field [0001] The invention relates to an amino acid-containing multi-element topdressing fertilizer, which belongs to the technical field of fertilizer making. The invention also relates to a preparation method of the topdressing fertilizer. Background technique [0002] The mid-to-late growth period of crops is a very vigorous growth period. There are many types and quantities of nutrients that need to be absorbed, and there is not much base fertilizer applied during planting, so topdressing is urgently needed. Now farmers topdressing, most of them are nitrogen fertilizers, and some topdressing potassium fertilizers, but it can't meet the various needs of potassium, nitrogen, zinc, boron, sulfur, phosphorus, etc. needed by economic crops at this time, and what farmers topdress High nitrogen and low potassium are not suitable for crop absorption at this time, and at the same time, there is a lack of other nutrients necessary for crops at this time. [0003] Moder...
