Pesticidal controlled-release fertilizer special for eucalyptus and preparation method thereof

Abstract

The invention discloses a pesticidal controlled-release fertilizer special for eucalyptus, which is composed of the following components in parts by weight: 250-450 parts of urea, 50-150 parts of diammonium phosphate, 100-300 parts of calcium superphosphate, 100-300 parts of potassium chloride, 1-5 parts of zinc sulfate, 1-5 parts of copper sulfate, 1-5 parts of borax, 10-20 parts of sodium humate, 10-20 parts of diatomaceous earth zeolite mixture, 10-20 parts of urea-formaldehyde resin, and 10-20 parts of carbosulfan and tebufenozide pesticidal mixture. According to the invention, the carbofuran and tebufenozide mixture is added into the fertilizer special for eucalyptus for the first time; the proportions of ingredients of the mixture are initially discussed. The invention further discloses a preparation method of the pesticidal controlled-release fertilizer special for eucalyptus simultaneously. The pesticidal controlled-release fertilizer special for eucalyptus disclosed by the invention is capable of effectively preventing insect attack, increasing the yield of eucalyptus, controlling slow release of nitrogenous fertilizer and controlled release of potassium, phosphorus and medium trace elements, increasing the fertilizer utilization rate, reducing the fertilization time and reducing the labour intensity of farmers.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a special fertilizer for insecticidal and controlled-release eucalyptus, and also relates to a preparation method of the special fertilizer for insecticidal and controlled-release eucalyptus. Background technique [0002] Eucalyptus is the general term for Eucalyptus myrtle species, most of which are tall trees, native to mainland Australia and neighboring New Guinea islands, Indonesia and the Philippine Islands. Eucalyptus is the tallest tree in the world, it can grow to 100-110 meters, the highest is 156 meters, and it is currently planted in 96 countries and regions. [0003] Eucalyptus has excellent characteristics such as fast growth, straightness, and resistance to drought and barrenness. It is mainly used in the production of high-performance eucalyptus recombined wood, bamboo and eucalyptus composite materials, thick-core eucalyptus solid wood composite boards, formaldehyde-f...

AI Technical Summary

Problems solved by technology

In terms of fertilizers, due to the differences in soil and eucalyptus fertilizer requirements in various stages of production, eucalyptus fertilization has not yet formed a unified fertilization technology in terms of fertilizer nutrients, fertilizer formula, fertilization amount, fertilization time, and fertilization methods. standard

In addition, pests such as termites, cutworms, and crickets have become important obstacles to eucalyptus production, causing certain losses to the quality of eucalyptus, and a lot of manpower and material resources are invested in prevention and control every year.

[0004] The special fertilizer for eucalyptus announced in the invention patent announcement number CN100424049C only supplements nitrogen, phosphorus, potassium and medium and trace elements, but in the published patent literature for special fertilizer for eucalyptus, there is no report of the same medicine and fertilizer

Another example is the invention patent announcement number CN102584438B, which uses rumen-passed fat as the inner layer. Due to the limitations of composite materials at that time, the slow-controlled release fertilizer invented by it has a poor slow-controlled release effect compared with the current high-tech composite materials. The layer is difficult to degrade in the soil, causing white pollution
