Preventive Measures of Apple Orchard in Low Temperature Period
- Smoke. Before the frost occurs ignite hay heap on the upper tier of the orchard / vineyard The smoke will cover the whole orchard subject to the slight breeze which will act as a blanket and prevent frost damage.
- Irrigation. Due to the specific heat capacity of water, it can regulate the alterations in temperature. Because of the increase of content in the soil moisture, the air near the ground will not immediately cool, so spraying before frost can prevent or moderate the frost.
- Ignite against frost candles. Before the frost, ensure you have purchased plenty of Crop Candle Bougies and place it between trees / Vines about 5M apart.
