Antifreezing system for Dangshan crisp pear tree in early spring and antifreezing method thereof

Abstract

The invention provides an antifreezing system for a Dangshan crisp pear tree in early spring and an antifreezing method thereof. The antifreezing system comprises a water supply system, a control system and a water spray system, wherein the control system comprises a main control panel, a control switch, a plurality of probe heads, a soil water content monitor and an audible alarm; the control switch is used for opening and closing of a water pump; and the plurality of the probe heads comprise a first temperature sensor, a second temperature sensor and a third temperature sensor which are arranged under the projection of a tree crown from top to bottom. With the method provided by the invention, the water spray system is operated according to changes of air temperature and soil water content which are monitored by temperature sensors and the soil water content monitor in real time; the environmental temperature and the soil water content of an orchard are controlled through underground water micro-sprayed from micro-spray pores of pipelines of the water spray system; thus, freezing injury of the Dangshan crisp pear tree in a flower season can be effectively prevented; meanwhile, water resource is fully utilized; and an energy-saving and environment-friendly antifreezing measure is provided for the orchard.

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
