Abstract

The invention discloses a fertilizer for enhancing plant disease resistance and a production process thereof, and belongs to the technical field of fertilizer preparation, the fertilizer comprises the following raw materials: urea, potassium dihydrogen phosphate, potassium nitrate, slow-release polyglutamic acid, an organic chelating agent, trace elements and a microbial agent. The preparation method comprises the following steps: 1, uniformly mixing urea, monopotassium phosphate, a potassium nitrate organic chelating agent and trace elements, heating to 60-80 DEG C, adding slow-release polyglutamic acid, and stirring and mixing to obtain a fertilizer base material; and 2, cooling the fertilizer base material to room temperature, adding the microbial agent, stirring and mixing to form loose particles, thereby obtaining the fertilizer for enhancing plant disease resistance. The technical problems that a common fertilizer is poor in effect, low in disease and pest resistance and short in fertilizer efficiency are solved, and the slow-release polyglutamic acid, the microbial agent and the microelements have a synergistic effect, so that the yield of crops and the resistance to germs and pests can be improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a fertilizer for enhancing plant disease resistance and a production process thereof. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the growth rate of plants. However, in recent years, due to the large-scale application of inorganic fertilizers and the lack of organic fertilizers, the soil is agglomerated, the air hole capacity is poor, and the plant roots are few and Poor pricking ability, unbalanced nutrients, and low resistance to diseases and insect pests limit the increase in crop production. Ordinary chemical fertilizers cannot effectively prevent crop diseases, and have no obvious repelling effect on various pests. After the application of ordinary chemical fertilizers, crop seeds germinate slowly, grow slowly, and have low ability to resist diseases and insect p...
