Spring tube fruit tree freeze protection
Spring peaches, apricots, apples, pears are in the bud stage, flowering period or young fruit period. At this time, if it is chilled, it will probably result in reduced production or even no harvest. The author reminded farmers that the relevant measures for prevention and control of freezing injury must be followed up in a timely manner: Whitening agent made of lime, sulfur powder, etc. is used to coat the trunk with straw or straw rope, plastic film wrapped around the main trunk, and main branch. Use crop stalks, weeds to cover the entire root plate of fruit trees or earthen the root plate to increase temperature and humidity. Irrigate with water or spray water to keep the ground temperature relatively stable. Smoke is ignited at night with sawdust, stalks or weeds to slow the cooling and cooling of the ground and increase the amount of heat in the air. Use targeted prevention measures against fruit trees that have been frozen. One is trimming at the right time. Pruning branches according to frost conditions promotes new shoots. Fruit trees with severe frostbite and loss of vitality should be dug up and replanted in time. The second is the timely prevention of pests and diseases. Frozen trees are debilitating and have poor resistance. They can easily cause resin and rot diseases in summer and autumn. Fruit trees should be disinfected with medicinal agents. The third is to strengthen soil fertilizer management. To apply special fertilizer for fruit trees, with spraying foliar fertilizer. In addition, we must cultivate loose soil and raise soil temperature.
