Detailed Explanation of the Latest Post-Harvest Management Points for Shatang Mandarin

Each year as the New Year approaches, it is time to harvest and market Shatang mandarins, and now that the New Year has passed, the Shatang mandarins have already been harvested, so it is time to begin post-harvest orchard management, which is related to next year's yield. So how should Shatang mandarins be managed after harvest? Let us find out together.

1. Spraying to clean the orchard

In a low-temperature environment, the growth of pests and diseases is not favored; at this time the pests and diseases have poor vitality and mostly gather together, making them convenient to control, and the effect is also the best. Before overwintering there are many pests and diseases, and according to the occurrence of these pests and diseases, effective pesticides should be selected for reproduction; overwintering pests and diseases have strong stress resistance, so pesticides with strong killing power and quick, long-lasting effect should be used. According to the variety of Shatang mandarin, tree age, climatic conditions and the occurrence of pests and diseases, select the appropriate pesticide, spray it in suitable weather, and spray the branches and leaves evenly; at the same time, combine it with foliar fertilizer spraying to quickly maintain nutrients and restore tree vigor.

2. Shaping and pruning

After the first spraying and before spring budding, the plants should be pruned; during pruning, diseased and insect-damaged branches and leaves as well as diseased fruit should be pruned away together, and at the same time the area around the orchard should be thoroughly cleaned; after sweeping the ground clean, take everything out of the orchard and burn it to eliminate overwintering sites for pests and diseases and reduce sources of pests and diseases. After pruning, promptly apply a healing agent to seal the wounds and protect them from invasion by pathogens. Weeds and parasitic plants should be comprehensively removed, and large-branch pruning techniques should be adopted to lower the height of the canopy, thin out overly dense or crossing large branches, and create a tree shape with good ventilation and light penetration and three-dimensional fruiting.

3. Topdressing

The winter fertilizer applied before and after fruit harvest is also called postpartum fertilizer; it can help the plants restore tree vigor as quickly as possible, has an excellent leaf-preserving effect, and can also extend leaf lifespan to avoid early defoliation and ensure stable and high yields the following year. After fruit harvest, combine spraying to clean the orchard and spray foliar fertilizer to supplement nutrients to the plants; this can improve the plants' stress resistance and promote flower bud differentiation. The winter fertilizer is mainly organic fertilizer, matched with an appropriate amount of compound fertilizer and micronutrient fertilizer; it can raise ground temperature, help the root system overwinter smoothly, and at the same time help the accumulation of plant nutrients, which is beneficial to flower bud differentiation the following year. After fruit harvest, apply quick-acting water-soluble fertilizer by drenching, mainly water-soluble fertilizer rich in humic acid, amino acids and high-grade nutrients, and apply it by drenching 1-2 times before flowering.
