Fertilizer composition for preventing and curing kiwifruit canker and preparation method thereof

Abstract

The invention discloses a fertilizer and pesticide combination reagent for preventing and killing bacterial canker of kiwifruit and a preparation method of the fertilizer and pesticide combination reagent. The fertilizer and pesticide combination reagent is prepared from the following raw materials in parts by weight: 200 parts of agricultural amino acid water soluble powder, 40-50 parts of anhydrous zinc chloride, 45-65 parts of anhydrous manganese chloride, 40-80 parts of a ciprofloxacin active compound or a ciprofloxacin active compound, 100-200 parts of a 14% methyl chloride isothiazolinone water agent, 100-150 parts of oxine-copper active compound, 0.1 part of forchlorfenuron, 0.1 part of a 5-nitroguaiacol sodium salt active compound, 0.5 part of an alpha-pimacol active compound, 350-450 parts of molasses microbial fermentation concentrate solution, 0.2-0.25 part of sodium polyacrylate powder, 50-60 parts of No.YD-7 liquid fertilizer synergia solution, 0.1-0.2 part of industrial alcohol and the balance of deionized water to supplement the raw materials to 1200-1250 parts. The fertilizer and pesticide combination reagent disclosed by the invention is a high-density liquid product with fertilizer and pesticide effects, has good affinity for both water and plants, mainly contact and kill plant bacteria, and can also kill pathogenic fungus. A layer of compact organic pesticide and fertilizer film is formed outside a tree body when the fertilizer and pesticide combination reagent is applied in large concentration, and a sustained release function is exerted.

Description

technical field [0001] The invention relates to the technical field of novel special functional liquid fertilizers used both as fertilizers and pesticides, in particular to a fertilizer-medicine combination for preventing and curing kiwifruit canker and a preparation method thereof. Background technique [0002] Kiwifruit canker is a devastating infectious disease caused by the "Pseudomonas syringae pathogenic type of kiwifruit" bacteria. The fungus is a low-temperature and high-humidity infecting pathogen, and it begins to spread when the ten-day average temperature reaches above 0°C in spring; when the ten-day average temperature is around 10°C, the disease is very easy to spread in the event of strong wind and heavy rain, continuous rain, and frostbite in winter; When the temperature rose to about 20°C, the germs stopped doing harm. Pathogenic bacteria are spread by media such as wind and rain, insects and gardening tools, and invade and reproduce locally from the outsid...

Problems solved by technology

The disadvantage is that water is used as a carrier with poor permeability. When the climate is dry, the paste on the trunk tends to fall off in lumps, and it cannot be used for the prevention and treatment of diseases on leaves and branches.
