This technology is suitable for winter wheat and rapeseed production areas.
First, technical content
1. Mechanized fertilizer. The use of top-dressing machines follows the agronomic requirements to complete operations such as trenching, fertilization, covering and repression at one time.
2. Mechanized plant protection. According to the condition of crop diseases, weeds and weeds, according to agronomic requirements, we should choose suitable plant protection equipment and chemicals, and apply pesticide or herbicide spraying to field crops.
Second, technical requirements
1. Mechanized fertilizer. 1 The top-dressing machine must have good inter-row passing performance, no obvious rooting and injury problems, covering after fertilization and repression and compaction. 2 The mechanical deep fertilization should meet the local agronomic requirements for crop cultivation, and the depth of fertilization should be greater than 6 cm; the implement should have a device that can adjust the amount of fertilizer, and there should be no broken bar during operation, and the broken bar rate of row fertilizer is less than 3%, and the fertilization position is accurate. Rate ≥ 70%, single-season work piece or fault repair does not exceed 1 time/piece (piece, group).
2. Mechanized plant protection. 1 Select the medicine according to agronomic requirements and spray at the designated plot in the appropriate proportion, application period and application amount. 2 The application of the spraying machine should be based on different spraying targets to select the spraying machine and matching spraying parts; the multi-headed spraying machine should pay attention to adjusting the consistency of the nozzle, the spraying amount and the spraying direction, and control the spraying amount. 3 When spraying, the walking speed should be uniform, and the adjacent journey should be closely connected with the ridge so as to prevent the heavy spray from leaking and spray evenly.
3. Grass damage prevention. According to the dominant species of crops weeds and the control time, choose the appropriate equipment, herbicides, and strictly in accordance with the provisions of the control object, the use of time, the use of dose and application methods.
Third, pay attention to matters
1. Pay attention to safety operations when performing plant protection operations to prevent possible hazards. Efficient, low-toxicity, low-residue pesticides and advanced and reliable application machinery should be selected and rational application methods should be adopted. There must be no leakage of the agent from the implement.
2. In mechanical plant protection operations, especially when using backpack-type plant protection equipment, the operating hand and related personnel must wear protective equipment, pay attention to the wind direction, and prevent personnel from inhaling pesticides to cause poisoning.
3. Spray work should avoid heavy winds, heavy rain, and heavy dew. When the wind power is greater than three, it must not be used.
4. After spraying or spraying herbicides every day, properly handle the remaining liquid and thoroughly clean the spraying equipment. The equipment is stored in a ventilated and dry place.
5. During the use and storage of plant protection machinery, care should be taken to prevent incidents that endanger humans and animals and pollute the environment.
