Timely burial of frozen water Before the soil freezes, use a plough to open the seedbed trails or furrows or manually dig a ditch, and then pour the frozen water down along the ditch. Therefore, when the soil begins to freeze, it contributes to the soil insulation and maintains sufficient moisture in the soil to meet the water consumption of the fruit trees during the winter.
Root-neck soil is used to cultivate 20 cm high ripening roots of the grafted fruit tree seedlings before freezing to prevent freezing of the root system to facilitate safe wintering of the seedlings.
According to the topography of the nursery, use the corn stalks before the soil freezes, set up a windbreak every 2-3 seedbeds (or seedlings), or pile up about 50 centimeters of soil on the northwest side of the young seedlings. Heap wind protection.
The seedlings shall be coated with 5 kg of quicklime and 0.5 kg of salt, respectively, and they shall be opened with water. After mixing and stirring, 0.5 kg of vegetable oil and 0.5 kg of lime sulfur are added to prepare whitening agent. Before the soil is frozen, brush or sprinkle on the seedlings to make the surface of the whole plant white or gray. This can not only reflect sunlight, prevent rapid temperature changes, enhance cold resistance, but also effectively control the wintering of the pests on the trunk.
