Talking about cold-proof cloth

Let’s talk about the quality of the old farmer’s wish for the cold-proof cloth. After covering the citrus, we must try not to affect the normal physiological metabolism of the fruit tree (respiration and photosynthesis), so the choice of cold-proof cloth must follow the air permeability and light permeability. 、The 3 principles of heat preservation, otherwise the cover film may be counterproductive. First, why choose cold-proof cloth with good air permeability? Citrus grows all year round, unlike peaches and plums, which fall dormant in winter. Now is the critical time for the differentiation of citrus flower buds. The tree itself needs to maintain its own respiration. If the airtightness is poor, it will affect the respiration of the fruit tree. In addition, if the air permeability is not good, the temperature in the film may be too high. Second, why choose cold-proof cloth with good light transmittance? Although the fruit trees are covered with film, the fruit trees still need photosynthesis to produce organic matter for the differentiation of fruits and flower buds. The most important thing for photosynthesis is to have light, so the cold-proof cloth should be selected with good light permeability. Otherwise, citrus trees may drop fruits and leaves. Third, why choose a cold-proof cloth with good heat preservation? The purpose of our covering film is to change the small environment around the tree when the temperature in the general environment drops sharply, so as to resist the cold air and avoid the influence of frost damage. When choosing a cold-proof cloth, avoid too high or too low temperature in the film to reduce the damage to citrus due to sudden cold and heat. Therefore, the material that heats up and cools quickly is not recommended! The old farmer's wish cold-proof cloth is a new type of cold-proof cloth on the market. It is different from the ordinary market's 2000-3000 hydrostatic pressure cold-proof cloth. The old farmer's wish cold cloth has a more mature 5-layer technology, and its hydrostatic pressure can reach more than 9000.
