Occurrence characteristics, mostly in the heart of the fruit and its fruit surface, sometimes the fruit surface performance is very obvious, the fruit peel was water-like, transparent wax, the internal space of the diseased fruit cells filled with sugar and water stains, disease The texture inside the fruit is harder and translucent, or spotted. The diseased fruit has a specific sweet taste, and there are more lesions near the top of the fruit or in the vicinity of the condyle.
Water heart disease is caused by sugar accumulation, calcium, and nitrogen imbalances that disrupt the normal habits of fruit, postponed harvesting of fruit, early fruiting of the tree, direct exposure of the canopy to sunlight, and sunburn symptoms. And in the regions where the temperature difference between day and night is relatively large during the near-mature period, fruits are susceptible to disease. The occurrence of large fruits is more frequent than that of small fruits. Usually, high-nitrogen and low-calcium fertilizers will increase the incidence of fruit. Different varieties, different disease resistance.
Prevention and control technology: strengthen cultivation management, increase organic, inorganic, biological bacteria fertilizer (Longfei three yuan), implement formula fertilization, avoid single application of ammonium nitrogen fertilizer, pay attention to farming protection, work pruning, clever fruit, adjust leaf fruit proportion.
The tree is supplemented with nutrients by: Stadkop+ calcium lactate or calcium lactate.
Through practice, this is an effective way to solve the disease.
