Strict drug use standard, scientific compounding liquid Soybean Soybean pre-emergence chemical weeding formula is: 48% chlorhexidine EC 70 ml 39% acetochlor EC 100 ml ten 70% fensulfuron soluble powder 2 g, water 30 kilograms, can spray one acre. When preparing mixed pesticides, first add the pesticides into the appliance according to the standard, then dilute the powder pesticides into mother liquor with a little water, add the equipment, and finally add the quantitative water. Do not add the water to the appliance before adding the liquid to prevent water. The medicine is not fully dissolved and the spraying is uneven, and the medicine is inferior.
Spray at the right time to ensure sufficient water. Soybean can not be sprayed immediately after spraying to prevent drought.
The spring breeze affects the efficacy, but it can't be too late. The correct method is: the plots with good sensation are sprayed 3 to 4 days after the sowing, and the plots with poor grievances are sprayed 4 to 5 days before the seedlings are unearthed. In the spring season, the general year is windy and rainy, and the soil is poor. Therefore, when applying pre-emergence weeding technology, we must pay attention to the sufficient amount of water. Take the air-jet sprayer pulled by the agricultural small four-wheel tractor as an example. Its weight is 175~200 kg, equipped with high-pressure nozzle, and the forward speed is the second-speed throttle, so that each tank can be sprayed with 6-7 mu to ensure the mu The amount of water is 30~35 kg. At the same time, depending on the soil moisture and climatic conditions, it is possible to refill the water at any time, 20~30 kg per mu to improve the efficacy.
Magnetic rail lighting is a flexible and adjustable LED track lighting system, which is achieved by installing magnetic rails and lamps on the ceiling or wall. The system consists of a magnetic rail, a light fixture and a power supply.
Rails are usually made of aluminum and have built-in magnetic bars that can be easily installed on areas that require lighting. The magnetic rail luminaire is connected to the magnetic rail by magnetic force, so that it can move and position freely along the track. This design makes the installation and adjustment of the lamps very simple, and the layout and location of the lighting can be changed at any time according to the need.
The magnetic lighting system has a variety of lamp types to choose from, such as spot lights, down lights, wall washers, etc., suitable for different lighting needs. Lamps can be flexibly angled to illuminate specific areas or objects while providing accurate directional lighting effects.
In addition to flexibility and adjustment, LED track lighting also has the advantages of high efficiency and energy saving. It uses high performance light sources such as LED to provide bright and uniform lighting effects while saving energy and reducing energy consumption.
Track lighting design is widely used in commercial spaces, exhibition halls, galleries and offices, and is also commonly used in home decoration. The advantage is that it can customize the lighting scheme according to different needs, creating the ideal lighting effect and atmosphere.
