Cucumber should generally be a round bar shape that is relatively uniform from top to bottom, but in production, there are often malformed melons such as sharp beaks, big bellies, slender waists, and curved melons. This not only affects the yield, but also seriously reduces the quality of the goods and causes extreme problems for the farmers. loss. The causes and prevention methods are summarized as follows: The reasons for the different types of malformed melons are not the same. In general, the lack of light during the growing period of the cucumber, the night temperature is high, the temperature difference between day and night is small, the irrigation water is often more and less frequent, easy to appear thin waist melon. Plants grow too profusely, causing melons and locusts to grow out of tune, or melon pods to get sick. The lack of nutrition during the growing period of the cucumber, the weak growth of the plant, or the serious harm caused by the worms, downy mildew and other pests, can easily grow into sharp-edged melons. During the growing period of cucumber, the temperature is high, the moisture is large, the plant grows more vigorously, the melon strip grows faster, or in the flowering stage of the cucumber, the temperature is low, the rainy weather, the ground temperature is low, etc., resulting in poor pollination, the apex of pollination first enlargement, lack of nutrition, or moisture Insufficient, uneven development of ovules, melon seed formation at the top, melons grow thicker, and melon seeds in the lower part of the seedless or seedless, melons grow thin, become a big pot cucumber. Cucumbers encounter low temperatures during the flower bud differentiation period, often forming ovary or four ovary locules, and it is easy to form short malformed melon balls. Malformed melons should take corresponding measures depending on the reasons for their formation. During the growing period of cucumber, especially in the period of squashing, cucumber can not be regarded as fertilizer and fertilizer, and a large amount of fertilizer and water can be applied, causing “running and runningâ€. Take the spring cucumber in the greenhouse as an example. After starting to harvest the melon, I will chase a fecal diluted body with about 2,500 kilograms per mu. I will chase the fertilizer once every 10 days or so. It is best to use chemical fertilizer and manure alternately and topically, between each top dressing. Fill the water once. Formula fertilization techniques should be used, or spraying potassium dihydrogen phosphate, N:P:K ratio 5:2:6, to give suitable temperature in the cucumber seedling stage, especially before two true leaves, when the temperature difference between day and night is required, The night temperature should not be lower than 10 ~ 12 °C, so as not to form a deformed ovary grow into a malformed melon. Temperature difference between day and night during the cucumber fruiting period also needs to be larger. During the melon period, the daytime temperature should not exceed 30°C. The night temperature requirement is: 16-18°C in the middle of the night and 13-15°C in the middle of the night. Strengthen the ventilation management to prevent over 30°C. °C high temperature, to ensure normal fertilization and fertilization, so that the thickness of the melon strip growth uniform. Good prevention and control of pests and diseases, especially prevention and control of cucumber downy mildew, the specific method is in the early stages of cucumber growth, we must always pay attention to the discovery of "central diseased plants," timely removal of diseased leaves, to prevent the spread of the spread, and at the same time pay close attention to spray 40% B Phosphorus and aluminum 300 times, or 2000 times the toxic venom, spray every 5 to 7 days, and even spray 3 to 4 times to control the spread of the disease. Keeping the healthy growth of melons, the melons can be significantly reduced.
