The principle of smoking to prevent frost was as follows: - Smoke could absorb long-wave radiation from the ground and radiate heat to the ground, reducing the net expenditure of heat on the ground, thus slowing down the rate of temperature drop and increasing the reverse atmospheric radiation. - When firewood burned, it released heat, which could locally heat the air near the ground and reduce the possibility of frost. - When the water vapor condensed on the smoke, it would release heat and raise the temperature. - The carbon dioxide, water vapor, and water vapor condensation in the air had a strong ability to absorb long-wave radiation from the ground. Smoke could increase the carbon dioxide content in the air and condense water vapor into fog, enhancing this absorption ability and returning more heat to the ground. The specific method of smoking: - Choose suitable materials, such as firewood, cow dung, sawn wood, waste engine oil, red phosphorous, or other dust and smoke substances that can produce a lot of smoke. - Ignite it half an hour or an hour before the frost. - Generally, when the temperature of the leaves drops to 1 ° C higher than the frost index, the smoking will begin (it can also be started when the temperature is close to 0 ° C). The lighting time should be uniformly announced. - In terms of specific operation, one could first insert a basic pile, spread a layer of dry firewood around the pile, cover it with a layer of wet firewood, and smear a thin layer of mud on the surface. Then pull out the pile, and when igniting, put the ignition material into the hole to emit a large amount of smoke. The number of smoke piles needed to be determined according to the terrain and materials. For example, in an orchard, 4 - 5 fire points could be set up for every 667 square meters of fruit trees, and each pile of materials was 15 - 20 kg, and it was located at the upwind.
