The herbicide should be selected according to the type of weeds in the corn field. Attention should be paid to the following matters during use:
(1) Strictly control the period of medication. Post-emergence weed control is generally safe at the 3 to 5 leaf stage of maize.
(2) Do not arbitrarily increase the dose. According to the specific conditions of weeds and corn fields to determine a reasonable amount.
(3) Improve spray technology. When spraying, pay attention to sensitive crops such as beans and cotton, pay attention to the direction of the wind, avoid the herbicides from drifting and produce phytotoxicity, spray the drugs in a pour-out manner, and spray uniformly; do not spray without spraying; when using paraquat or other antibiotics To protect the sprinkler head.
(4) Pay attention to the weather conditions during application. It is not applied on rainy days and hot noon days; amide herbicides are easy to produce phytotoxicity on rainy days and high humidity.
(5) Measures should be taken promptly after the occurrence of phytotoxicity in corn. If corn leaves exhibit yellowing or whitening symptoms, they should be immediately watered in sufficient quantities to reduce the relative concentration of the drug in the crops; removing the heavy leaves from the victim to avoid conduction; topdressing quick-acting fertilizers to promote rapid seedling growth; Spray antidote (920, etc.).
Laser rangefinder module, which has two application, one is mainly designed for long distance range finder, another is for secondary development industrial Laser Distance Sensor, which support ttl/usb/rs232/rs485 adapter output data.
