For cold hardened species such as white wax, thousand-headed oysters, and sycamore, after the autumn planting, measures such as cold watering, rooting, rooting, tying up grass ropes, wind barriers, etc. can be taken. Measures such as irrigation before the cold and soil cultivation in the rhizome must be carried out for all trees planted in the autumn. The whitening, the tying of the rope, and the wind barrier can be determined according to the cold resistance of the plants, the winter temperature conditions, and the microclimate environment. One of these can also be used interchangeably.
Film coating method
For less hardy species can be taken to cover film. Arbors: should be wrapped with straw rope first, and then cover the film, and then use the thickening of the agricultural cover from the top to the roots. The top must be tightly sealed. The plastic film must be wide and it must not cling to the trunk. It is surrounded by bamboo sticks. After the roots are filled with frozen water, roots and stems, etc., they can be covered with rice straw, wheat straw, corn stover, sawdust, etc., and finally covered with plastic film. Shrubs: The shrubs are of lower height and are less affected by wind force. The roots and crowns of nursery stocks can use two flexible bamboo sticks (about 3 cm in width). The two ends are sharpened and intercalated around the plants. The dome is about 15 centimeters from the crown of the plant, about 10 centimeters from the side of the plant, and 4 to 6 centimeters deep into the soil, and then covers the agricultural film. After the cover of the agricultural film is covered, cover it with soil again. Matters needing attention: film coating time and film removal time should be subject to weather conditions. Filming time is best when the initial frost, the film should be uncovered after the temperature is basically stable, the tree began to sprout. In sunny weather in winter, it is appropriate to remove the membrane for ventilation and supplement oxygen. In the snow, the accumulated snow on the roof should be cleaned in time to facilitate the plants to receive the light.
