An early spring antifreeze system and antifreeze method for Dangshansu pear fruit trees

Abstract

An early spring antifreeze system and antifreeze method for Dangshansu pear fruit trees, the antifreeze system includes a water supply system, a control system, and a water spray system. The control system includes a main control board, a control switch, multiple probes, a soil moisture monitor and an audible alarm, the control switch is used to turn on and off the water pump, and the multiple probes include the first temperature set from top to bottom under the canopy projection sensor, a second temperature sensor, and a third temperature sensor. In the method of the present invention, the water spray system is operated according to the temperature sensor and the real-time monitoring of the soil water content monitoring instrument and the change of the soil water content, and the groundwater sprayed out by the micro nozzle holes of the pipeline in the water spray system is used to adjust the ambient temperature and soil of the orchard. The water content can not only effectively prevent the frost damage of Dangshansu pear tree flowering period, but also make full use of water resources; provide an energy-saving and environmentally friendly antifreeze measure for orchards.

Description

technical field [0001] The invention relates to a plant antifreeze system and an antifreeze method thereof, in particular to an early spring antifreeze system and an antifreeze method for Dangshansu pear fruit trees. Background technique [0002] In recent years, in Dangshan County, Anhui Province, the main production area of ​​Dangshansu pear cultivation, during the early spring flowering period of Dangshansu pear, the temperature in the pear orchard often appears low temperature, and the flowering period of Dangshansu pear is easily damaged by low temperature, and the low temperature in the pear orchard often occurs at night, which is often regarded by people If neglected, it is easy to cause frost damage during the flowering period of Dangshan crisp pear. For Dangshansu pear flowers that were seriously damaged by low temperature frost, the stigma of the entire inflorescence was blackened and necrotic, and they could not be fertilized and set fruit, resulting in no product...

AI Technical Summary

Problems solved by technology

For Dangshansu pear flowers that were seriously damaged by low temperature frost, the stigma of the entire inflorescence became black and necrotic, and they could not be fertilized and set fruit, resulting in no production in the year of cultivation, which seriously damaged the economic income of fruit farmers; Moreover, there are many rust spots or frost spots on the fruit surface, which affects the commodity value of the fruit, reduces the market competitiveness of the fruit, and reduces the income of the fruit grower.

At present, in the cultivation and production of Dangshansu pear, the early spring Dangshansu pear is damaged by low temperature during the flowering period, and there is no good solution
