Problems solved by technology

Most of the current water-soluble fertilizers are liquid fertilizers, and there are relatively few solid water-soluble fertilizers, and many solid water-soluble fertilizers still have a series of problems in the product quality and manufacturing process, such as: (1) Fertilizer elements are all in an ionic state, and each nutrient component is easily antagonistic , the utilization rate of nutrients is low; (2) The product is prone to moisture absorption and caking, especially in the process of processing, storage and transportation; (3) Most solid water-soluble fertilizers have low active ingredient content, and the plant utilization rate Low, easy to cause pollution to the environment, and there are many insolubles, the dissolution rate is slow, and it is easy to block the nozzle and drip irrigation pipeline
These greatly limit the field application of water-soluble fertilizers

Abstract

The invention discloses a water-soluble fertilizer containing L-lysine and a preparation method thereof and belongs to the technical field of the fertilizer. The water-soluble fertilizer is prepared from urea, calcium superphosphate, monopotassium phosphate, fermenting freeze-dried powder, ammonium molybdate, magnesium sulfate, ferrous sulfate, sodium silicate, anti-caking agent and synergetic agent at certain weight ratio. The water-soluble fertilizer is high in water solubility, is non-caking and has comprehensive and balanced nutrient elements; various nutrition elements are free from any antagonism and fully meet the requirement for nutrition of the crops; the water-soluble fertilizer is capable of promoting the balanced absorption for the nutrition of the plant and especially has an obvious effect for increasing yield and income of the fruit and vegetable crops. Besides, according to the invention, the synergetic agent prepared from polyacrylic acid-polyglutamic acid block copolymer and L-lysine at weight ratio of 1:2 is capable of obviously increasing the use ratio of the fertilizer and the crop yield and quality can be obviously increased under the synergic effect of the synergetic agent, the anti-caking agent and the fermenting freeze-dried powder.

Description

technical field [0001] The invention relates to a water-soluble fertilizer, in particular to a water-soluble fertilizer containing L-lysine and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and chemical fertilizers are the material guarantee for the sustainable development of agriculture and the basis for increasing grain production. The practice of the world's agricultural development has proved that the application of chemical fertilizers is the fastest, most effective and most important measure to increase production. However, the irrational use of chemical fertilizers over the years has not only resulted in a large amount of waste of economy and resources, but also caused a series of environmental problems such as a large number of fertile fields with acid and alkali, cracks, and groundwater nitrate exceeding the standard. In addition, environmental problems such as excessive nitrate in vegetables, increased emis...
