1. Cold proof: waterproof and cold proof to prevent frost.
2. Waterproof and air permeability: prevent the high temperature in the
film from causing sunfruit; it is conducive to flower bud
differentiation and reducing the probability of large and small years;
it is impervious to water, frost, snow and freezing rain; under high
temperature, the shed is naturally ventilated and ventilated without
burning the tip or fruit.
3. Promote coloring: bright color, good appearance, good fruit coloring, low yellowing rate.
4. Reduce the shrinkage rate of Citrus in the mature stage, reduce the
fruit drop, and reduce the average fruit drop rate by more than 30%;
5、沙糖橘留树不摘，能保持果品新鲜，错开集中上市，减轻采摘、运输、贮藏等压力。（如：广西沙糖桔正常气候为11-12月份成熟，如果采用了树冠盖防寒布避雨避寒栽培可延长至 1～3 月份采收，有利于错锋上市。）
5. It can keep the fruit fresh, stagger and concentrate on the market,
and reduce the pressure of picking, transportation and storage. (for
example, the normal climate of Guangxi orange is mature from November to
December. If the tree canopy cold cloth is used to avoid rain and cold,
the harvest can be extended to January to March, which is conducive to
the listing of staggered front.)

6. No shed, save time and labor, reduce cost, reduce the probability of
freezing in the shed under low temperature, and maximize the quality of
fruits in low temperature areas.
7. Green environmental protection products: made of degradable polymer, new concept of environmental protection agriculture.
