Causes and prevention of watermelon hollow skin thickness

As a fruit, watermelon plays an important role in people's lives and is favored by people. However, in recent years, the decline in commercial properties due to the thickness of watermelon hollow skin has occurred frequently, causing great losses to the farmers. Hollowness of watermelon refers to the phenomenon that the melons in the melons have voids or cracks, which greatly affect the yield and quality. The hollow thick-skinned malformed watermelon is the loss of edible value when the physiological disease is more common and the yield is reduced. There are many reasons for the thick and hollow watermelon skin, which is mainly related to climate, management techniques and varieties. The prevention and control measures for watermelon thick and thick skin are introduced as follows:

Variety selection: With the market demand and scientific and technological progress, there are more and more varieties of high quality watermelons. When selecting a variety, melon farmers should first understand the characteristics of the selected varieties, and it is best to select some varieties that can resist hollow diseases. Secondly, select the varieties that are suitable for local cultivation conditions and are suitable for the current market.

Fertilizer management: Watermelon has a short growth period and a large amount of growth. Therefore, watermelon needs a large amount of fertilizer, and it is necessary to rationally coordinate the use of organic fertilizer and chemical fertilizer. Generally, organic fertilizer is the main (80%), supplemented by chemical fertilizer. Fertilization should be based on the base fertilizer, accounting for 60% to 70% of the total fertilization, supplemented by topdressing, accounting for 30% to 40% of the total fertilization. After the test, borax can prevent and treat hollow diseases, and the application of sufficient amount of boron fertilizer will facilitate the transportation of nutrients to the heart and become a thin and solid melon. Use 100 grams of borax per acre of melon, first dissolve it with a small amount of hot water and add 50 kilograms of water. Spray 1-2 times on the leaf surface before the flowering of watermelon. It can also be applied to the seed hole when planting watermelon. Use borax 1-1.5 kg. During the fruit expansion period, watermelon often ends prematurely due to lack of water and enters the mature stage. Therefore, the cells are not enriched, causing the cell wall to rupture, resulting in hollow watermelon. Generally, it should be mastered that the amount of water to be watered before fruit setting is small and the number of times is small. After the melon is depilated, increase the amount of watering and increase the number of watering, and pour it once every 3 to 5 days. The ditch irrigation can be gradually increased from small to large, and must not be rushed until the ripening of the watermelon. Heaven can stop.

Receive melons at the right time. According to the distance of the fortune, the maturity of watermelon harvesting is determined. For 7-10 days, it is advisable to harvest 7-8 mature watermelons. For 3-5 days, 8-9 mature watermelons can be harvested. 9 Long-distance transportation of mature watermelons is prone to hollowness, especially for the easy-to-open hollow sorghum varieties.
