Watermelon is split

Temperatures have changed greatly since entering May . The maximum temperature during the day is sometimes above 30 °C, and the night temperature is sometimes only below 10 °C, and continuous rainfall. In Baoding City and some counties and cities in Langfang City , the temperature dropped to below 10 °C on the night of May 11. On the 17th , Gu'an County in Langfang City and Zhangzhou City in Baoding City were hit by strong winds, hail and heavy rain. Such conditions such as temperature and climate, rainfall and cooling have a great impact on the growth of watermelon in the melon period, and it is inevitable that watermelon melons will appear.

 

In addition, the factors that cause watermelon cracking include: the reasons for the variety. The differences between different varieties are large, and the cultivation habits of vegetable farmers are also different. The varieties of cracked melons are all thin, crisp, and large and medium-sized varieties are easy to split. Before the melon is sitting, the soil is dry for a long time, and suddenly the water is suddenly poured into a large amount of water or it is easy to cause cracked melon. When the fruit develops at a low temperature, it grows slowly, and then rapidly expands to cause a split melon. Fertilizer application in the expanded melon period is unreasonable, a large number of partial application of nitrogen fertilizer, lack of trace elements calcium, boron, etc., the melon skin expansion is slow, and the contents rapidly expand and cause cracked melon. When using a hormone such as melon, excessive use and the like may cause cracking.

 

The current watermelon cracked melons are related to recent strong winds, rainfall, cooling, and hail. The recent continuous rainfall, cooling, and watermelon in the growing stage caused the surface toughness of the watermelon to decrease. As the weather cleared and the temperature increased, the watermelon was in a period of vigorous fruit development. The growth rate of the internal material was higher than that of the melon skin, resulting in watermelon. Split melon.

 

How to prevent cracked melon: In the selection of seeds, we must first choose watermelon varieties with high toughness, cold tolerance, drought tolerance and crack resistance. The drainage of watermelon in the open field should be done as much as possible. In case of heavy rain, the water in the melon field can be removed in time. Try to plant some high-stalk crops in the watermelon field to cool down and damp. The cultivation density of watermelon should be moderate, so that ventilation and light can be achieved. Keep an eye on the weather changes and take measures against wind, warmth and cold. Strengthen management and pay attention to the rational use of nitrogen, phosphorus and potassium.
