Non-woven Fabric Cold Protection Application Method

Non-woven fabrics are now in the early winter season, in the face of all kinds of "cold winter" speculation, how should seedling producers and garden managers do a good job of "preventing frost damage", and what landscaping cold cloth materials are available? Plant cold and frost protection, which is one of the contents of natural disaster prevention and control, is no exception. A set of scientific and reasonable seedling cold protection plan is a prerequisite to ensure that plants are protected from frost damage or reduce frost damage loss. Physical cold protection essentials: 1. Plant protection experts said that the main body of the green cold protection cloth is the cold protection of plants. Pay attention to cold damage above zero degrees Celsius, frost damage below zero degrees Celsius, and sudden and unexpected frost damage in early autumn and late spring. There are many ways to prevent cold and frost in garden plants, both physical and chemical. 2. For marginal plants, newly transplanted plants, weakened plants and plants introduced from high temperature areas or exotic areas, early protection should be used, and cold cloth or cotton quilt should be used. 3. For woody plants, especially trees, it is necessary to protect the "rhizosphere" (that is, the base of the trunk below 30 cm on the surface where the trunk connects with the main root). The "rhizosphere" of plants is like the human heart, if the rhizosphere is frozen, it will be difficult for the plant to slow down. Jiang Sandeng also said that the antifreeze of the rhizosphere is the top priority, which can be mainly cultivated and sealed, taking into account other shielding technologies to protect. 4. Trees in public places such as corridors, forest belts, street trees, and embankment trees (mainly newly planted trees in the past 5 years) should be generally "painted white" or wrapped in grass ropes, cotton canvas cloths, green non-woven fabrics, etc. before winter. 5. The cold protection of ground cover plants, to water fertilizer before wintering, to promote growth, increase nutrition as the main countermeasure, outdoor potted plants should be moved into the greenhouse or greenhouse in time. For cuttings, building a small arch before winter can have both cold protection and seedling cultivation. In addition, irrigation of "frozen water" is also one of the main measures to prevent cold. Experts remind that the timing of freezing water must be mastered, and before winter, the timing of green soil "freezing at night and daytime" is suitable.
