Problems solved by technology

Relatively speaking, the fumigation method is widely used in frost prevention, but it also has certain limitations. For example, the fumigation method has a better preventive effect in a relatively closed area. In the prevention of large-scale vineyards, the effect is better. At the same time, the fumigation method is greatly affected by the wind, and a slight blow will cause the smoke to not completely cover the crops, and the fumigation can only increase the surface temperature by 1-2 degrees, which is not effective for strong low-temperature freezing damage good preventative effect
Irrigation can increase the thermal energy and thermal conductivity of the soil; at the same time increase air humidity and reduce radiative cooling, but it can only increase the ground temperature by about 1 degree, and water resources are limited, so it is impossible to irrigate at the same time
Covering with straw curtains, films, etc., has a good frost prevention effect, but due to the high cost of materials and labor, it can only be applied to small areas

Embodiment 1

[0019] A kind of grape frost prevention method, this method comprises the following steps:

[0020] 1. Prepare frost prevention materials: collect and store the waste wood used for lighting fires and the smoke materials used for fuming in advance, and manage them in a unified manner so that they can be uniformly deployed during frost prevention. The waste wood is hard and fire-resistant. Abandoned wood, smoked material is a mixture of straw, hay, sheep manure and fallen leaves.

[0021] 2. Make aerosol: dry the sawdust and sieve it, then mix the sawdust, ammonium nitrate, sulfur powder and waste diesel evenly, and the weight percentage of each raw material is 55% of sawdust, 25% of Powder 15%, waste diesel oil 5%, mix evenly and store in boxes or bags. The size of the aerosol is 25cmX15cmX30cm.

[0022] 3. Temperature detection: strengthen the frost forecasting work with the local meteorological department, and at the same time use a temperature monitor to detect the temperat...

Abstract

The invention discloses a grape frost preventing method. The method comprises the following steps that frost preventing materials are prepared; a smoke agent is manufactured; the temperature is detected; frost preventing arrangement is carried out; frost is prevented. According to the grape frost preventing method, the temperature of a grape orchard is raised with the main measure of lighting open fire for raising the temperature with the cooperation of smoking, different temperature raising measures are adopted in different temperature stages, the open fire lighting temperate raising and smoking temperature raising are matched, the limitation brought to the grape industrial development by frost is overcome, and the defect of a single measure adopted in the prior art is overcome. By means of the grape frost preventing method, frost invasion is effectively prevented, the preventing effect on low-temperature late frost damage is especially obvious, and the yield of grapes is ensured. Materials are easy to obtain, cost is low, and good application prospects and use value are achieved.

Description

technical field [0001] The invention belongs to the technical field of viticulture, and in particular relates to a method for preventing grape frost. Background technique [0002] "Frost" is a disastrous weather phenomenon, which means that during the growing season, the soil surface temperature at night or the air temperature near the plant canopy drops to 0°C or below in a short period of time, and the temperature on the plant surface drops rapidly, causing grapes Young parts are injured, water in the plant freezes, metabolic processes are disrupted, cells are squeezed by ice and cause damage. When frost occurs, the plants are harmed by the low temperature, not by the frost alone. A late frost is a frost that occurs during the transition from a cold season to a warm season. From the case analysis of late frost, it can be concluded that late frost is a short-term low-temperature disaster that occurs when the weather is clear at night after an obvious precipitation process...
