Anti-cold tips for fruit trees in winter are extremely effective

In winter, the cold, long-lasting cold often causes a lot of damage to the agricultural industry, including farming and livestock. For fruit trees, if there are no measures to protect the tree against the cold, it can cause the tree to decrease in yield and die. To protect crops in winter, people should apply measures against cold for fruit trees timely and properly.

1. Apply measures to care for fruit trees properly in the cold season

If the fruit trees are not cared for properly on cold, freezing, cold days, the tree will be very vulnerable, creating conditions for pests and diseases to attack, causing reduced yield and death of the tree. To combat cold for fruit trees in the winter, people need to apply appropriate care including:

  • In order to limit the condition of plants being weakened in the cold season, growers can use straw, hay, nylon, … cabinets around the base of the tree to keep the plants warm. Apply straw 1-2cm high, about 30-40cm wide on top to keep warm and limit weed growth.

  • For seedling gardens, people use white plastic bags or white newspapers to cover the surface of the beds to limit the cold wind.

  • For trees that have been damaged by the cold but can still be restored, people will whitewash the stumps and root cabinets. At the same time, water, care and fertilize properly for the tree to recover quickly.

2. Supplementing nutrients for plants

To limit the condition of the tree weakening in winter, people add enough nutrients to the tree. For fruit trees that have budded, people water them enough to keep them moist.

Fertilize fruit trees early, around the beginning of February. People fertilize a balanced amount of nitrogen, phosphorus, and potassium in the ratio 1:1: 1. Potassium fertilizer has the effect of reducing the viscosity of the primary substance. of cells to facilitate physiological and biochemical processes in fruit trees. From there, it helps the tree to function properly, increase its ability to absorb nutrients and enhance its resistance to cold.

If the fruit tree has dark green leaves, it is a sign of excess nitrogen. At this time, people stop fertilizing nitrogen, add potassium and super phosphorus to balance. Can spray more potassium Multi-K through the leaves 1-2 times. Timely addition of potassium through leaves, especially in cold weather conditions, when the temperature drops below 10 degrees Celsius, making it difficult to absorb nutrients and water of the roots is the way to fight cold for plants to eat. effective efficiency.

For branches that have not yet sprouted buds, people should thinly prune branches, overhanging branches, and branches affected by pests and diseases to keep the canopy open. It is possible to use a specialized growth agent for fruit trees to spray the tree. Spray on the bud stage 2 times, 10 days apart each time, 3 – 5 days before flowering and when the tree sets fruit. In the young fruit stage, spray one more time with a concentration of 10 ml/20 liters of water on an area of ​​300m2 of foliage. Growth substances will help the plant to set more fruits, large fruits, early ripening fruit 10-15 days before the crop, increasing the value of the product.

3. Prevention of pests and diseases in the cold season

In cold, wet weather conditions, it will create conditions for pests to attack. Therefore, in the measures to combat cold for fruit trees, priority should be given to the control of pests and diseases.

One of the diseases that often appear during this period is late blight, leaf spot disease, which mainly harms litchi, longan, mango, oranges, tangerines, grapefruits… To prevent these diseases, people use them. specific intravitreal drugs, such as: Aliette 80WP; Ridomil Gold 72%; Alpine 80WP, Ricide 72WP with a concentration of 0.2%, spray 2-3 times. Conduct spraying before blooming 5-7 days, spray 15-20 days apart/time. If it rains after 4-6 hours, people do not need to spray again. Intravitreal drugs usually have a lasting effect after 15 – 20 days of spraying.

To combat cold for fruit trees and help them recover quickly, farmers can combine some fertilizers with growth regulators to increase cold tolerance, helping to increase fertilizer absorption in poor conditions. cold weather. Combine fertilizers Brassinolide 0.15% SP + Potassium Hydrogen Phosphate (MKP, KH2PO4) + Compound Sodium Nitrophenolate 98%TC to water plants.

Applying the right anti-cold measures for fruit trees will help plants grow in the winter. In the spring, the tree will sprout, budding fruit with high yield and stable quality.
