The management of late-maturing red Fuji apple from fruit ripening to winter pre-shearing period not only relates to the quality of apple in the year, but also the level of commodity rate, and it plays a key role in the growth and development of fruit trees in the coming year. Therefore, the following management work should be done. 1. Tied insect traps Red-and-white spiders that cause damage to fruit trees such as red-and-white spiders, blackfly whitefly, and leaf roller moth, crawling down the trunk in the form of larvae or adults before the onset of winter, and latent wintering in cracks in roots and roots. After the outbreak of spring in the following year, it climbs along the trunk and climbs up the parasite hazard. Using the habit of pests, it can trap the insect trap on the trunk, which has a strong temptation to pests. 2, timely removal of bags in addition to bags as early as possible, the fruit surface back from the poor green, dark color, thick skin, poor appearance quality; bags in addition to the evening, the color is light, low sugar content, timely removal of bags in order to obtain high quality bagged fruit. Generally, the growth time of the apple in the bag is 90-100 days, and the bag can be removed 15-30 days before the normal harvest of the fruit. The Fuji apple has a sugar content of 12% or more, and the fruit surface is more than 70% green to remove the bag. 3. Put a reflective silver film under the canopy immediately after removing the bag to increase the light and promote coloring. The retroreflective film laying during this period can effectively increase the reflection intensity by 60%-70%, significantly increase the coloring degree of the pods in the fruit trees, increase the sugar content of the fruits, and remove the film within 1-2 days before fruit harvesting. Prepare for the next year. 4. The surface of freshly-picked and freshly-picked fruit is relatively young and has poor adaptability to the outside world. Insects and insect pests are easy to invade. At this time, an appropriate amount of bactericidal agent and calcium supplement should be sprayed, and agricultural anti-120 agent should be sprayed with 150 times. Dasheng M-45 68.75%, DuPont Yi Bao 1200-1500 times or 70% thiophanate-methyl 1000 times, calcium can use Stir calcium, CA2000 calcium treasure and so on. 5, picking leaves and turning fruit timely removal of fruit around the shading leaves, paste fruit leaves, yellow leaves, leaflets, thin leaves, picking the total amount of leaves accounted for 15% -20% of the total amount of the ideal light transmittance of 30% is better When the fruit light receiving surface meets the requirements, gently turn the fruit and color it on the other side. If necessary, fix it with tape. 6. After clearing the fruit trees in clear gardens, the leaves, weeds, rotten fruits, etc. of these overwintering pests should be promptly cleaned up, buried deeply or burned, and the old rough skin and rot should be scraped and burned. Then spray lime sulfur mixture, agricultural anti-120 and other fungicides, the pest eradication in the initial stage.
