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
