1, check the lesions and cure. On the basis of annual curettage, do a good job in the autumn scraping. In summer, new lesions were removed in time, and ulcers were completely scraped off in the fall. When scraping a lesion, it must be scraped into a good phloem. The wound was shuttle-shaped, with smooth edges, and scraped between yellow and green. The scraped bark must be burned and coated with bactericide. Such as: 2% sodium humate 30 times, 30 times the United States, Formamide, 70% thiophanate-methyl WP 30 times. In order to prevent long-term exposure of xylem after scraping, it can be coated with coal tar bituminous paint.

2. Apply basal fertiliser to fruit trees in a timely manner to supplement the tree nutrient consumed by the tree due to the result. Maintain a good tree vigor. In order to improve the resistance to rot disease.

3, do a good job in field cleaning, timely removal of litter and diseased branches, reduce the initial infection source of bacteria.

4, timely cut off the diseased branches in winter cut. Protect large wounds in time and reduce the chance of germ invasion.

5, in early spring on the tree (before germination) spray 5 degrees of lime sulfur, the main spray trunk, dry, main branch base. The site of attack is focused on spraying.

6. In the orchards that are more serious in rot disease, heavy scraping of the skin was carried out in June and July, scraping 0.5 to 0.8 mm, showing yellow-green inter-phase. Scrape the bark and clean it. After 10 days, it can be coated and protected.

7. Grasp the top-dressing work before germination, rapid growth of new shoots, fruit enlargement, flower bud physiology, morphological differentiation, increase organic fertilizer, thinning and fruit thinning, reasonably burden yield, and increase tree resistance.

8, for the larger lesions, the spring can be used late budding apple varieties of annual branches, in order to improve the tree's nutrient transport channels, thereby restoring the tree vigor.

Saury

It takes at least 2 months for Pacific saury to be directly sold or processed.How to effectively maintain the nutritional value and flavor of saury has also become a research hotspot. At present, the easiest and most effective way to store saury is freezing. The lower the freezing temperature is, the more beneficial it is to maintain the quality of saury. It can only be stored for 180 days at -20°C, and -30°C is the suitable temperature for freezing saury.
