Barbecue
Wire Mesh refers to the use of metal mesh processing, used in
hotels, restaurants, barbecue shops, picnic, camping, military, tourism and
other activities of pasta, meat, fish barbecue, and steaming, smoked and other
appliances. The main features of the barbecue grill netting are high
temperature resistance, no deformation, no rust, non-toxic, tasteless and easy
to use. In addition, our company can design and produce according to the
customer's shape and style.
Classification: According to the shape is divided into: round flat barbecue grill
mesh, round concave Barbecue Wire Mesh, square plane barbecue net, square
concave bbq mesh
According to the material is divided into: galvanized iron
wire barbecue grill netting, galvanized steel wire barbecue mesh, stainless
steel barbecue net.
Material: Disposable material: Galvanized redrawing wire
Disposable mesh edge material: tin plated iron sheet
(also known as tinplate)
Repeatedly use barbecue mesh material: medium carbon
steel wire, stainless steel 304.
Surface
treatment: Zinc plating, electrolysis, polishing, chrome plating,
nickel plating, copper plating and other processes.

First, the cause of deterioration
One is to re-apply fertilizer, causing soil compaction. Second, the salinization is aggravated. The third is to neglect the application of micro-fertilizer, which leads to various deficiency syndromes in the process of vegetable growth. Fourth, the continuous cropping is serious and the farming is extensive. Years of continuous cropping will cause accumulation of pathogens and eggs in the soil, and it is easy to induce various diseases of vegetables.
Second, governance countermeasures
1. Rotation: It is not suitable for a variety of vegetables in the field. It can be used for rotation and other types of vegetables, such as melons and onions, which can reduce the occurrence of pests and diseases. Note that certain leguminous vegetables should be arranged in the rotation to increase the nitrogen content of the soil by means of nitrogen fixation by symbiotic rhizobium; some mustard, peas, etc. can be arranged in the rotation to absorb phosphorus and potassium which cannot be utilized by ordinary vegetables. Some of them have been re-transformed into the soil with available ecology, which has improved the nutritional status of phosphorus for the sorghum vegetables.
2, rational farming: with the application of organic fertilizer, and gradually deepen the tillage layer. Winter ploughing can be used to promote soil ripening in summer and autumn, ensuring loose soil layer and improving soil fertility.
3, application of organic fertilizer, and application of micro-fertilizer: multi-application of organic fertilizer, under the action of microorganisms, the formation of an organic colloidal humus to improve soil agglomerate structure, enhance permeability and water retention and heat storage capacity, ease soil Salinization, combined with the fertilizer characteristics of different vegetables, reasonable formula, scientific application of micro-fertilizer. For basic fertilizer application, zinc fertilizer (zinc sulfate) can be applied for 1-1.5 kg per mu, boron fertilizer (borax) is generally applied 0.3-0.5 kg per mu, and molybdenum fertilizer (ammonium molybdate) is generally 0.1-0.2 kg per mu. Wait. For root dressing, zinc sulfate can be used in 0.05%-0.2%, borax can be used in 0.1%-0.25%, and ammonium molybdate can be used in 0.02%-0.05% to meet the demand for trace elements in vegetables.
4. Actively promote micro-ecological fertilizers: Micro-ecological fertilizers are environmentally-friendly fertilizers, which can improve soil aggregate structure and have comprehensive nutritional characteristics. Cao Dihuan

At present, the problem of soil environment deterioration is common in old vegetable fields, causing serious diseases and insect pests, and the decline in vegetable quality and market competitiveness. The reasons and treatment measures are as follows:
