In the face of cold wave, frost, how to cope with the orchard?

Fruit trees are greatly affected by the weather, in the face of such meteorological disasters as cold wave and frost, how to deal with them?

Cold wave
Cold waves are often accompanied by rain, snow or freezing frost. The severe cooling caused by the cold wave in winter has caused extensive freezing damage to the fruit trees in northern China and serious freezing damage to the fruit trees in southern China. Cold wave in spring often causes frost damage to fruit trees. Although the cold wave in autumn is not as violent as in winter and spring, it can cause frost, so that crops can not mature normally and reduce production.

Protective measure
In fruit growing areas, orchards are protected by open heating, mulching, windshields and arched sheds. For overwintering crops, in addition to selecting excellent frost resistant varieties, pre-winter management should be strengthened to improve the frost resistance of plants. In addition, the ecological conditions of farmland should be improved. For example, winter irrigation, grazing, soil loosening, suppression, manure (or soil) and other measures can be taken when winter wheat overwintering to achieve the purpose of preventing cold waves.

frost
Frost refers to the phenomenon of plant damage or even death when the temperature drops to 0 ° C or below. Frost does not necessarily occur when frost falls, but there is often frost when there is no frost. This kind of cream is also called inner cream, dark cream or killing cream. Spring frost has a certain freezing effect on the young flowers and leaves of fruit trees erupting in spring, and even causes no harvest in severe cases.

Protective measure
Due to the great impact of frost, defensive measures should be taken as early as possible in areas with frequent frost to protect the yield of fruit trees from being affected. There are three widely used preventive measures: taking measures to avoid frost, slowing the rate of cooling of plants, and improving the frost resistance of the crops themselves, which are effective not only in growing fruit trees, but also in other crops.

Fengtu agricultural weather station, it can comprehensively monitor and record temperature, humidity, wind speed, wind direction, rainfall and other important environmental parameters. By using this instrument, agricultural producers can not only get first-hand agro-meteorological data, but also help them have more time to take measures in advance to avoid losses, making agro-meteorological services more targeted and guided.
