First, double coverage: in the greenhouse to cover the film or add a small arch. Covering the film can increase the surface soil temperature by 2°C. Adding a small arch can keep the temperature of the vegetable growing environment above 15°C.
2. Disinfection of garden soil: Use 3-5 grams of carbendazim or methane bromide per square meter of bed soil to kill pathogens in the soil and prevent the occurrence of soil-borne diseases.
Third, to improve the way of membrane: Use bamboo wire to replace bamboo scaffolding membrane, use plastic rope instead of bamboo sticks as climbing objects, can reduce the degree of shading, and increase photosynthetic efficiency.
Fourth, improve the way of irrigation: the use of drip irrigation or submerged under the film, can make the relative humidity of the air within the shed reduced by more than 10%.
Fifth, the use of non-dropping film: the shed will not condense water droplets, light transmittance of up to 98%. If you use a general film, you can apply metronidazole or daily cleaning on the film to eliminate water droplets on the film and enhance light.
6. Scraping wood ash: The cedar is often sprinkled with haywood ash, which can prevent the occurrence of damping-off disease, blight and other diseases, and promote the healthy growth of vegetables.
VII. Increasing CO2: Combustion of biogas in the shed increases the temperature of the shed and adds carbon dioxide gas.
8. Set the light curtain: Set a light curtain on the rear wall of the booth and the vertical floor at the bottom to enhance the light in the low light area and increase the ground temperature by 2°C to 3°C.
Nine, the application of growth regulators: the correct use of exogenous plant growth hormone can promote plant growth and prevent flowering and fruit drop.
X. Ingenious application of drugs: The use of dust, smoke and other methods of spraying, neither the spray application of the law of the humidity increased defects, but also simple and easy, and stable and lasting efficacy.
JRT usb interface distance sensor board adds a USB port to a Laser Distance Sensor, inexpensive laser distance measurement sensors, allowing customers directly using GBeacon-2.3-Fx.exe software to control the rangefinder sensor. Usb laser distance sensors are the the most popular model devices, it works by measuring the phase of an visible-red laser beam that reflects on the target. Usually, customers would like to choose CH341SER.EXE version to test.
