AI Technical Summary

Problems solved by technology

Not only is the process long, but also requires 5-6 times as much water as a solvent for complexation. If the product is a liquid, it is very inconvenient to store, transport, and use. If it is made into a solid powder, it needs to remove a large amount of water, which consumes a lot of energy.
The obtained product is a single complexing agent complex, and the stability of the complex is poor, which is not conducive to plant absorption

Abstract

The invention provides a nutrient balance agent, the components include 10-45% of complexed boron, 40-80% of complexed iron, zinc, manganese and molybdenum, and 5-20% of complexed copper by weight percentage. Among them, the complexed boron is hydroxyl ammonia organic complexed boron, the complexed iron, zinc, manganese and molybdenum are EDTA complexed mixtures, and the complexed copper is mixed amino acid complexed copper. Its production process is to prepare complexed boron, complexed iron, zinc, manganese, molybdenum mixture and complexed copper respectively, and then mix them evenly in proportion, dry at 90°C until the water content is less than 2%, and crush to 40-60 To obtain the present invention. When used, the dosage is small, the complex has high stability, the effect of increasing production is remarkable, and it is beneficial to the protection of the ecological environment. Its production process is solid-solid catalytic complexation, the operation is greatly simplified, the amount of solvent is greatly reduced, and the energy consumption is low.

Description

technical field [0001] The invention relates to a fertilizer and a production method thereof, in particular to a nutrient balancer and a production process thereof. Background technique [0002] Trace elements are indispensable and important elements to promote plant growth, iron, zinc, manganese, molybdenum are all important enzymes [0003] One of the components is involved in the metabolism of carbohydrates and promotes nutrient absorption. Boron is beneficial to the growth of plant roots. These elements can form water-insoluble precipitates with phosphate radicals, which greatly affect the absorption of crops. Chinese patent 200510094167 discloses a competitive complexation production method of a high-concentration trace element foliar fertilizer. The complexing agent is EDTA, which is produced in a two-step process. First, EDTA is complexed with magnesium, manganese, and zinc, and then with iron and copper. replacement. Not only is the process long, but the complexati...
