Corn fertilizer having pest resistance

Abstract

A corn fertilizer having pest resistance is composed of 40-45 parts of urea, 10-15 parts of potassium sulfate, 12-15 parts of calcium bicarbonate, 8-12 parts of biochar, 5-10 parts of boric acid, 2-5parts of sodium citrate, 2-8 parts of manganese sulfate, 10-20 parts of plant ash, 8-12 parts of magnesium sulfate, 3-5 parts of a sodium alginate solution, 0.5-0.8 part of a biological agent, 5-10 parts of traditional Chinese medicine extract product and 4-6 parts of a urease inhibitor. The corn fertilizer having pest resistance can provide good nutrition elements for corn, facilitates the prevention of root pests and root diseases of corn, does not cause soil hardening, and improves the soil quality; and the biochar is added into the fertilizer, so the traditional Chinese medicine extract can immersed in the pores of the biochar after undergoing ultrasonic treatment, thereby the fertilizer efficiency and the pest and disease resistance period can be prolonged, and the quality of the cornis improved. A preparation method of the fertilizer has the advantages of simplicity, easiness in implementation, and significant economic benefits. The fertilizer does not cause acid-base imbalanceafter being used; and the biological agent added to the feed increases beneficial bacteria in the soil and further increase the fertility of the soil.
