The reader asked: Recently there have been many malformed melons on cucumbers, especially large-bodied melons and sharp-legged melons. How is this going to happen and how can we prevent it? The expert Wang Zaiqiang replied: The appearance of cucumber with malformed cucumber is a common phenomenon in the production process. The production of malformed melon directly affects the commodity and economic benefits of cucumber. When there are more, it will cause some loss to the farmers and there will be malformation. There are many reasons. The following are the causes and prevention of malformed melons. I hope to help everyone. First, the main reasons for the formation of Taligua melon: 1. Due to continuous cloudy rain or high temperature and drought, cucumber insemination is incomplete, and seeds are only produced at the apex of melons, which leads to a particularly enlarged pulp in the apex. 2. Because of soil acidification and salinization, the growth of cucumber plants is weak, malnutrition or excess nitrogen fertilizer, and low potassium fertilizer can also cause big cucumbers. 3. Melons in the process of expansion, such as early lack of water, and later a large number of water supply, can also form a large pot of watermelon, the recent continuous rain did not promptly rule out the field caused by stagnant water is another major reason for the appearance of large cucumber. Second, sharp mouth melon formation reasons: 1. Due to the recent continuous raining, the number of bees is low, and when cucumbers are not pollinated at flowering, the cucumbers are parthenocarpic and prone to sharp-edged melons. 2. Due to soil acidification and salinization, heavy use of chemical fertilizers again, excessive soil salinity leads to high soil solution concentration, root damage, and inversely proportional nutrient in the soil and plant nutrient, resulting in insufficient plant Nutrients, there will be sharp mouth melon. 3. Due to the early growth of plants, the supply of nitrogen fertilizers is insufficient, making the stems thin and tough. Third, prevention and control methods: 1. Based on the rational use of nitrogen, phosphorus and potassium fertilizers, Chong Shijia has fulvic acid organic fertilizer or sea-shaped double-algae fertilizer, which increases organic matter content, stimulates root growth and nutrient supply, changes the root growth environment, and reduces the number of malformed melons. 2. Reasonable watering, do not flood irrigation, so that the soil can see dry see wet, continuous drainage and fertilizer timely flood, to avoid excessive field water. 3. Fertility report agricultural nutrient solution 750 times liquid or Jintai Long top dressing 600 times liquid treasure or dougui 518 liquid fertilizer 750 times (each pot of water plus brown sugar 22), increase leaf and fruit nutrient supply.
