Method for safely overwintering grafted fruit trees
The fruit trees that were grafted at the beginning of the year were healed because of the wounds, and they were poor in stress resistance and susceptible to freezing injury in winter. In order to ensure safe wintering of the first grafted fruit seedlings, the following method should be adopted. 1. Fill the frozen water timely. Before the soil freezes, the seedlings trails or furrows are ploughed with furrows or artificially ditchered, followed by pouring frozen water into the ditch, and the perfusion must be filled. 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. 2. Root and neck soil. Before the freezing, the root of the grafted fruit tree seedlings is cultivated to a depth of 20 cm to prevent the roots from freezing, so as to facilitate safe wintering of the seedlings. 3. Set the cold barrier. According to the terrain of the nursery, use corn stalks before the soil is frozen to set up a windbreak every 2-3 seedbeds (or seedlings), or pile up a mound about 50 centimeters high on the northwest side of the young seedlings for wind protection. . 4 seedlings dry white. Take 5 kg of quick lime and 0.5 kg of salt, respectively, to open it with water. Mix and stir to add 0.5 kg of vegetable oil and 0.5 kg of lime sulfur to prepare a 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.
