Oranges are trimmed and cleaned in time after picking
After harvesting citrus fruits, it's crucial to perform timely garden maintenance. Here are some effective management techniques:
1. **Pruning**: If the orchard is densely planted or the canopy of mandarin oranges has become closed after fruiting, it's advisable to remove the central main branch and cut away branches that block light. This helps improve air circulation, sunlight penetration, and makes it easier for pesticide and foliar fertilizer application. At the same time, clear out weeds, trim dry, diseased, or damaged branches, as well as weak, shaded, or overcrowded shoots. Remove all fallen leaves from the ground and burn them in a centralized area to eliminate pest and disease habitats. Try to retain branches that have already produced fruit. Additionally, use a "clear garden" agent to kill overwintering pests and diseases, reducing their population for the next season. The best time to apply this treatment is usually 15–20 days after fruit picking, once the trees have recovered.
2. **Orchard Cleaning**: After fruit harvest, use a specialized spray like Kezi to clean the orchard. The primary goal during winter is to target red spider mites and reduce their egg-laying activity, thereby minimizing their overwintering population. Killing even a single cricket in winter can prevent it from laying eggs, which significantly reduces the number of crickets in the following years.
**Application Method**: Mix Krypton at a 1500:1 ratio. Krypton Emulsion is a thick liquid, so two dilutions are recommended. First, mix a small amount of fresh water with Krypton, then add more water to achieve a uniform solution. For optimal results, use a clear, sun-exposed water solution and mix it with Kotel in a 1:1 ratio. Spray thoroughly on the tree canopy and surrounding areas to ensure maximum coverage.
These practices not only enhance tree health but also contribute to long-term pest control, making the orchard more productive and sustainable.
