Wheat to promote weak to strong so good spraying effect

Stainless steel spiral nozzle for atomizing spray gun

In many nozzles, atomizing spray gun silicon carbide spiral nozzle is a great feature. With the continuous small spiral body, the slurry through the spiral line tangent and bump, constantly changing direction, spray into a thin sheet of concentric shaft cone, and the liquid from the nozzle cavity into the outlet of the channel are not hindered. The atomizing spray gun system still has high absorption power at low working pressure, and is approved by the system.

Technical Key Points of Forestry Science and Technology Disaster Relief and Mitigation in Response to Severe Drought

Spring is the key period for most tree species to blossom, sow and start a new round of seedling growth cycle. Excessive drought will adversely affect the normal physiological process and flower bud differentiation of trees or seedlings, as well as the smooth emergence of seeds after sowing, which will lead to the decline of the yield and quality of forest seeds and seedlings, and affect the smooth development of forestry production. According to the weather and drought, soil moisture, combined with forest and species conditions, scientific analysis and effective measures can greatly reduce the harm caused by extreme drought and minimize the loss.

Popular Science Knowledge: Precautions for Safe Operation of Agricultural Machinery

Plant protection machinery 1. The operator must understand the knowledge of the use of machinery and the nature of the agent, and master the measures to prevent poisoning and rescue methods. 2. The operator must wear protective equipment before operation. After operation, all body parts and protective equipment in contact with drugs must be washed with soap and water. 3. If the wound is not healed, lactating women, pregnant women, children and other personnel who are not suitable for operation shall not watch in the operation field. 4. The medicine box, pipeline and interface of the working machine shall not leak, and the working pressure shall not exceed the specified value during operation. The pressure in the box shall be removed before troubleshooting and disassembly of joints and nozzles.

Wheat to promote weak to strong so good spraying effect

If weeds are not treated in autumn in time before winter, chemical weeding can be carried out as early as possible from the period of winter wheat turning green to rising. The temperature fluctuates greatly in early spring, so clear weather should be selected for chemical weeding in wheat fields, and a boom sprayer should be used for chemical weeding from 10 am to 4 pm. Reasonable selection of boom sprayer, the use of boom sprayer for prevention and control operations, so as to achieve uniform spraying, no leakage of spray, no heavy spray, to prevent pesticide damage; The overlap of the handover line shall not be more than 3% of the working width, and the same crop in the same plot shall be completed within 3 days. It is not suitable to operate under the conditions of wind force exceeding level 3, heavy dew, rain and temperature above 30 ℃.
