There is a need for fruit wintering, whether in the subtropical or temperate planting, high and low temperature changes are more sensitive, frost and cold damage often occur in different degrees, citrus trees in the protection of freezing will consume a lot of nutrients, reduce the resistance of the tree, affect the flower bud differentiation of the year, reduce the production of the following year. Serious will also occur skins, dry water, peel oil plaque disease or direct freezing of bad fruit, deciduous fruit drop, directly resulting in economic losses.

When the temperature is below 10 degrees, there is often a low temperature fruit drop phenomenon. The fruit drop condition is related to the temperature positive and negative, the winter low temperature fruit drop period from December to early February, the peak of fruit drop in the coldest.

Many fruit farmers think that it is wrong to do enough to freeze the anti-freezing measures without covering the film. Cover film is equivalent to the fruit tree covered with a layer of quilts, is a physical insulation, just as it is cold to wear cotton-padded jacket, it is also very necessary.

So why is it necessary to say the cover film?

Citrus fruit drop, is due to low temperature caused, and AI nong cold cloth by adding special factors, with windproof and waterproof performance, in the cold winter rain weather, cold cloth for fruit trees to cover the wind and rain, cloth temperature than the outside world temperature is several degrees, that is, this several degrees of warmth, can greatly reduce the fruit drop rate of citrus.

Other than thatCold clothManufacturer Tip: To prevent citrus flowers fruit drop to take the right medicine citrus growth process often appears falling flowers fruit drop phenomenon, seriously affecting fruit sitting rate and yield, reduce farmers ' income. 1. Flowering circumcision in the flowering period from May to June, the use of ring cutting technology, with a blunt blade in the trunk smooth ring cut deep up the xylem, 1 hours later smear "to promote Kao 2nd", to protect the fruit, control summer tip pumping. 2. Spraying flowers to protect fruit fertilizer citrus flowering period is more sensitive to pesticides, the flowering period is forbidden to use drugs, so as not to cause drug damage, resulting in poor pollen. In the pre-flowering, young fruit period, fruit expansion period spray to protect fruit fertilizer, with "melon and fruit strong ling" + 0.3% urea +0.3% phosphoric acid two potassium hydrogen, improve the fruit sitting rate and fruit expansion speed. 3. It is an important way to greatly reduce the fruit drop of falling flowers by fully pollination and pollination in the flowering period of orange orchard Bee and artificial pollination. Therefore, artificial pollination or bee-making during flowering can significantly reduce the fruit drop of falling flowers. 4. Strengthen the cultivation and management of undernourishment weak tree potential, flower fruit dysplasia is easy to fruit drop flowers, but the growth of the tree is also often the result of strong branch growth potential, affecting the development of flowers. Therefore, the control of fertilizer, to prevent excessive hair tip, all have the effect of improving the rate of fruit. 5. Control the summer tip crazy artificial wipe out the summer tip, reduce the fruit nutrition competition, improve the fruit rate; in summer pruning to increase the body ventilation and light transmittance, pruning should be thin fiber branches, disease and insect branches at the same time cut off, pruning caused by the wound with "callus anticorrosive film" smear. Through pruning, improve the photosynthesis of the leaf surface, concentrate the nutrient supply flower fruit, improve the fruit sitting rate.
