First, the causes of fruit cracking
Fruit cracking is often triggered by environmental stress during the later stages of fruit development. High temperatures, intense sunlight, and dry soil can cause the fruit's skin to harden prematurely. When a sudden increase in rainfall or moisture occurs, the pericarp (outer layer) and pulp tissues grow at different rates, leading to an imbalance that increases internal turgor pressure. This pressure can cause the fruit to crack. In summer, when hot and dry conditions are followed by heavy rain or flooding, fruit cracking becomes more common.Second, prevention measures
1. Choose varieties that are resistant to cracking and have lush foliage, such as Maofen 802, Zhongshu No. 6, Zhongza No. 9, 2402, and others. These varieties are less likely to develop cracks under stressful conditions. 2. Improve field management by increasing organic fertilizer application to enhance soil structure and water retention. Water the plants regularly, especially during the fruiting stage, keeping the topsoil consistently moist. Avoid overwatering or letting the soil become too dry before heavy rain. After rain, ensure proper drainage to prevent waterlogging. Prune the plants timely to maintain a dense canopy, which helps protect fruits from direct sunlight. Harvest fruits before the rainy season to reduce the risk of cracking. 3. Apply drought and water retention agents. These products help the soil retain moisture for longer periods. When the soil is wet, they absorb and store water, releasing it gradually when dry. This keeps the roots hydrated and reduces the chances of fruit cracking. 4. Use fruit bags during the early growth stage. These bags protect the fruit from sun exposure, rain, and pests, significantly reducing the likelihood of cracking. You can use kraft paper or even apple bags for tomato fruit bagging. 5. Spray a solution of 0.1–0.3% calcium chloride on the fruit. This treatment strengthens the fruit's cell walls, making it more resistant to cracking under sudden changes in moisture levels. By implementing these strategies, growers can effectively reduce fruit cracking and improve overall yield and quality.Thyroid Pack,Sterile Thyroid Pack,Disposable Thyroid Pack,Disposable Thyroid Surgical Pack
