Tree insect pest preventing and controlling process method

Abstract

A method for preventing and curing pests of trees belongs to the technical field of a method for processing trees, which comprises the following preparations and the process for preventing and curing trees, firstly, the process for preparation is that biomass gasification oil tar is reacted with NaOH or KOH for 30-80 minutes and is added with H2O to be diluted to make trees preventing and curing process preparation, and the weight ratio of biomass gasification oil tar: NaOH:H2O is 1:10.-0.4:0.5-2.0, and the weight ratio of biomass gasification oil tar:KOH:H2O is 1:0.1-0.5:0.1-2.0, and the biomass gasification oil tar is bamboo oil tar or wooden oil tar or grass oil tar, secondly, the trees preventing and curing process is that the preparations prevent and cure pests of trees by adopting ways of tree trunk injection or tree root irrigation or stems and leaves spray or essential positions coating, the method for preventing and curing pests of trees has the advantages of low manufacturing cost, excellent disinfecting effect, and little environmental affect.

Description

technical field [0001] The invention belongs to the technical field of tree treatment methods, in particular to a tree disease and pest control treatment method. Background technique [0002] Biomass gasification tar is a dark brown oily substance condensed at room temperature from the gas collected after pyrolysis of plant materials and their processing residues. It mainly includes bamboo tar, wood tar and grass tar. Bamboo tar is the residue of bamboo processing By-products obtained by high-temperature pyrolysis, wood tar is a by-product obtained by high-temperature pyrolysis of wood processing residues and husks, and grass tar is obtained by high-temperature pyrolysis of herbs, crop straws and crop husks by-products. At present, in the process of processing bamboo, wood and straw into corresponding bamboo charcoal, charcoal and peat, due to the use of modern machinery for efficient production, the by-product-tar produced in the production process has not found its use an...

Problems solved by technology

Judging from the situation of eradication and treatment in various places over the years, a lot of manpower, material resources and financial resources have been invested, but the actual situation is not ideal. The main measures taken are to clean up diseased and dead trees, and the method adopted is to generally carry out large-scale clearcutting

The effect of this method is unsatisfactory, and there are many disadvantages: first, it is difficult to control the quality of clear felling, the cutting pile is high, and the branches are not cleaned thoroughly, leaving hidden dangers; Large numbers of trees descending and circulating everywhere, making quarantine lockdown very difficult

Injection of imported and domestic nematicides has a certain effect in the prevention and control of nematodes, but the workload is heavy and the cost is high. According to the injection cost of 30-50 yuan per pine tree, the cost is high, and it is impossible to promote the application on a large scale.

From the point of view of ecological control, transforming the stand structure is theoretically a fundamental way. Disease-resistant tree species can play a certain role in disease control, but the cultivation of disease-resistant tree species takes a long time and cannot be popularized in the short term.
