Antifreezing method for pear trees in flowering stage

Abstract

The invention relates to an antifreezing method for pear trees in a flowering stage. The antifreezing method for pear trees in the flowering stage particularly comprises the following steps: (2) heat insulation of pear trees, (2) heat insulation of soil, and (3) artificial pollination. According to experiments, by the antifreezing method for pear trees in the flowering stage, the fruit setting rate of the pear trees is guaranteed effectively. Compared with the prior art, the antifreezing method for pear trees in the flowering stage has the characteristics that the fruit setting rate of the pear trees is even increased by more than seven percentage points, and the effect is remarkable. Meanwhile, compared with trunk whitewashing and smoking antifreezing, the antifreezing method for pear trees in the flowering stage is simple to operate, is safe and reliable, does not cause any potential safety hazards, and is worthy of being popularized and used widely.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and in particular relates to an antifreeze method for pear tree flowering. Background technique [0002] In the process of pear tree cultivation, the flowering period is an important period that determines the fruit setting rate and fruit quality of pear trees. Among them, antifreezing during the flowering period of pear trees is of great significance for preserving flowers and fruits. Pear trees bloom early, and the flowers are neat. Frost during the flowering period will cause great losses, and there may even be a possibility of failure. Therefore, pear trees must be well protected against frost during the flowering period. [0003] The commonly used antifreeze measures during the flowering period include watering during the flowering period, whitening the trunk, and fumigation for antifreezing. Among them, quicklime is often used for whitening the trunk, which may easily cause excessive calc...

Problems solved by technology

[0003] The commonly used antifreeze measures during the flowering period include watering during the flowering period, whitening the trunk, and fumigation for antifreezing. Among them, quicklime is often used for whitening the trunk, which may easily cause excessive calcium ion concentration in the soil and affect the fruit setting of pear trees, while fumigation prevents frost. It uses smoke to reduce the radiative evaporation of soil heat. At the same time, smoke particles can absorb moisture, condense water vapor into liquid and release heat, and increase the temperature. However, smoke can easily cause air pollution, and there are fire hazards. It is actually risky to use it for soil insulation. huge
