Pay attention to the following points in the fall and winter law:
Autumn and winter law Tong water and fertilizer management. In order to enhance the lignification strength of the seedlings, stop watering before entering the autumn. From October to November, the water can be sprayed with a new high-fat film to protect the sputum, and the winter water will be flooded before the end of November to facilitate safe wintering. Dig 3 to 4 deep 50 cm to 100 cm points outside the canopy of the tree, and apply fertilized fertilizers such as horse manure and broken grass to increase the ground temperature. Decomposition of organic fertilizers releases heat and increases soil fertility. Spraying hibernation in time before hibernation can catalyze the massive replication of hibernating factors and rapidly produce hibernating compounds, so that the overwintering plants can sleep well as early as possible, and accumulate enough energy for the healthy growth of plants in the coming year.
Autumn and winter law Tong plastic shaping. Pruning can be carried out in autumn and winter when the leaves of the leaves are frozen, the soil is frozen, and the tree is dormant until the spring sap flows. The wound caused by pruning should be applied in time to prevent the anti-corrosion film, and protect the wound from healing tissue growth and prevent infection from wounds.
Autumn and winter law Tong cold measures. The plastic trunk can be used to wrap the trunk tightly, and then wrapped with straw rope, which is both moisturizing and cold-proof, and then the root of the tree is covered with a plastic film to keep the survival rate of the next year. Whitening the trunk can reduce the damage caused by the temperature difference between the sun and the bark of the sun, and eliminate the wintering pests in the gap of the bark of the paulownia. The whole plant sprays the tree guard general, which can not only protect the temperature of the tree itself, but also disinfect the smothering type to eliminate the bacteria and reduce the occurrence of frost damage.
