Problems solved by technology

Copper preparations are generally used for kiwifruit canker, and the copper ion content is above 100ppm. If copper preparations are used for root irrigation and base fertilizer, while inhibiting pathogenic bacteria, it will also kill beneficial bacteria and inhibit plant growth. Excessive copper ion content in water may cause environmental pollution

Abstract

The invention provides a zirconium-containing nano slow-release anti-ulcer fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer production. The fertilizer comprises the following components in parts by weight: 50-60 parts of zirconium-containing nano soil material, 5-15 parts of zeolite powder, 0.005-0.01 part of copper sulfate, 0.001-0.005 part of ammonium molybdate, 0.1-0.2 part of zinc sulfate, 1.5-3.0 parts of vitamin C, 16-20 parts of organic matter, 0.005-0.01 part of bacillus subtilis, 5-10 parts of urea, 15-20 parts of monoammonium phosphate, 15-20 parts of potassium sulfate and 15-20 parts of water. In the invention, zirconium elements which are beneficial to human bodies and kiwi fruits and have little influence on soil environment are selected according to the difference of the cell structures of pseudomonas syringae, bacillus subtilis and kiwi fruits and the tolerance of the pseudomonas syringae, bacillus subtilis and kiwi fruits to zirconium elements, and the novel fertilizer of zirconium-containing nano soil material can be prepared by the technological measures of chelating, compounding with a nano structure slow-release material and the like, so that the growth of kiwi fruits can be promoted, the quality of kiwi fruits can be improved, and pathogenic bacteria such as pseudomonas syringae can be effectively killed.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a zirconium-containing nano slow-release anti-canker disease fertilizer and a preparation method thereof. Background technique [0002] Kiwifruit canker is a devastating disease caused by Pseudomonas syringae, and its incidence rate ranks first among the top ten bacterial plant diseases. The canker caused by it has broken out in various kiwifruit producing countries and has a tendency to spread all over the world. It has caused huge economic losses to agricultural production in various countries and seriously threatened the safe production of kiwifruit in my country and the world. [0003] At present, there are mainly biological and chemical means for the treatment of kiwifruit canker, but there are certain limitations. [0004] In fact, many beneficial bacteria and their secondary products have a strong killing and inhibiting effect on Pseudomonas syringae, but it ...
