Corn mechanized plant protection operations should pay attention to what problems?

(1) before the operation of the spraying machinery to check and adjust, check the drug tank and nozzle whether there is a running phenomenon, whether the connection parts are tight, whether the transmission parts are flexible, whether the pipeline is smooth, whether the spray pump pressure is normal, whether the spray volume of the nozzle spraying is consistent.

(2) according to determine the amount of field spray and nozzle flow control operating speed, generally should be controlled at about 4 km / h, uniform speed. Fast drug is not enough, slow easy to cause drug damage. To avoid heavy spraying and leakage spraying.

(3) master spraying time, sunny days and high temperatures should be avoided from 11 a.m. to 2 p.m. this time, so as to avoid high temperatures and evaporation fast to reduce the effectiveness of the drug.

(4) The direction of travel of the unit should be perpendicular to the wind or at an angle. First start from the downwind head, the wind speed is greater than 3 should stop the operation.

(5) spraying operators should wear protective clothing, protective masks and masks to prevent contact with drug poisoning. Sprayed agent place to make a mark, in order to prevent human and animal poisoning.

(6) The operation site is not allowed to drink, eat and drink, smoking; the exposed part of the human body should be avoided and direct contact with the agent. After operation, hands, feet, face, nose and mouth should be washed. Shoes, hats, gloves, masks, overalls, etc. are not allowed to bring into the residence without washing.

(7) After the end of the operation, should choose the appropriate place to clean the machinery, to prevent pollution of water.
