How to prepare for the antifreeze in the orchard or vineyard?

Orchard Management | How to prepare for antifreeze in orchard or vineyard?

Recently, a new round of cold air will wreak havoc all over the country next week, and the fruit trees have just begun to encounter cold air when they are "out of power"! Freezing damage will reduce the yield of your fruit trees and, in severe cases, cause fruit trees to die. Are you ready to protect them? We have compiled the following cold protection measures for reference:

1. Insufficient irrigation water in winter: After one and a half months of fruit picking, dit the trenches between the rows of fruit trees, and then pass through the water. The amount of water should be infiltrated before entering the night. Before entering the winter, the fruit trees should be irrigated 1 or 2 times, so that water can be used to raise temperature, increase temperature and reduce freezing damage.

2. After the winter, the roots and grasses should be covered in time: after the winter, the wheat straw, straw, and the corn stalks are evenly covered between the rows of fruit trees, which can block the cold wind from invading the rhizome, reduce the freezing damage, and reduce the evaporation of soil water to protect the temperature. After the action, and the cover rots, it can also become an organic fertilizer for tree growth. Before covering, you can firstly soil the roots of the fruit trees by 10-20 cm, which is more effective against cold intrusion, especially for young trees, which can avoid freezing damage.

3. The tree body wrapped in straw: before entering the winter, wrapped with straw ropes on the trunk or main branches. It can not only prevent cold wind invasion, but also reduce the loss of trunk water. Before winding, it is best to immerse the entangled material in lime water for 1-2 days to disinfect and prevent the pests from invading the fruit trees.

4. Whitening: The formula of white paint is: 10 parts of quicklime, 1~2 parts of salt, 35-40 parts of water. The lime is turned off with water, slag is removed, poured into brine, and stirred evenly. Evenly whitening the trunk and main branches of the fruit tree can prevent freezing, sunburn, and killing germs, eggs and adults hidden in the trunk. It can also be used to wrap young branches with weeds and plastic film, and it can also play a role in antifreeze.

5. Orchard smoked: It should be used in the coldest night in winter. At about 11 o'clock in the cold night, in the corner of the wind orchard, use the firewood, rice husks, clam shells, sawdust, litter, etc. as fuel (note the control of the fire), smoky fire, so that the smoke covers the whole garden, and let the smoke cover the entire park.

6. Skillfully applying grass ash to increase fertilizer and increase temperature: The plant ash is rich in certain potassium, and it is applied to the orchard soil in winter, which not only looses the soil, absorbs heat and heat, reduces freezing damage, but also provides potassium, phosphorus, calcium, silicon and a variety of mineral nutrients for fruit trees. Generally, 200-300 kg of ash is applied per acre of orchard, and the soil can be applied to the soil 3 to 5 cm deep, but generally the orchard with larger saline-alkali is not suitable for application.

7. Binding the windbreak fence and setting up the wind barrier: the terrain is flat. On the northwest side of the orchard, branches and hay are used to construct a windproof fence or windshield that is about 1 meter high to protect the root neck from freezing. For small-area young orchards, sorghum and corn stalks can be used to set up wind barriers every 2 to 3 rows of saplings.

8. Protect the wound: the wound is larger, usually wrapped in a plastic film a few times in the wound of the fruit branch, pay attention to the closure when the binding is tight, this method can promote wound healing and fruit trees antifreeze, timely loosening after winter.

9. Use the antifrost candles. We are professional antifreeze candles manufacturer from China. We have our own factory and we will provide you a competitive quotation if you want an order.
