Management Techniques for Large Suli Pear Trees After Transplanting

In the winter of the year of transplanting, the old scaly bark on the trunk and main branches must be thoroughly scraped off, and the scraped debris should be collected and burned. After scraping, the trunk or large branches should be coated with whitewash or sprayed with 5-degree lime sulfur mixture. For disease spots such as rot on the branches, use a knife to scrape the disease spots clean, then apply 40% asomate 50-fold solution. During the growing season, strengthen pest and disease control to preserve leaves and promote branch growth.

2. After sawing off large branches of transplanted large trees, smooth the wounds and apply 800-fold carbendazim solution for protection to prevent infection. Larger wounds should also be sealed with clay, then wrapped tightly with plastic film.

3. In the year of transplanting, keep the soil moist, strengthen fertilizer and water management, and cultivate frequently to encourage as many new branches as possible, so as to help restore normal tree growth.

4. Some transplanted large trees, due to damage from rot and dry rot, gradually die back on new small branches, but the roots do not die. Before sprouting in the second year, saw off the diseased trunk at 60 to 80 cm above the ground and top-graft Suli pear or pollinator varieties. After grafting, smear the wounds with clay, then wrap tightly with plastic film.
