The malformed cucumbers affect quality and economic benefits, and many farmers are also very distressed and actively seek solutions. According to Zhu Qingshan, senior agronomist of the Agriculture and Forestry Bureau of Beichen District, Tianjin, there are four types of malformed cucumbers. One, tipped melon. The main reason for the occurrence of pointed squash is that the cucumber is weak in parthenogenesis and the female flowers in the flowering stage are not fertilized, resulting in malnutrition at the tip of the fruit. Prevention measures create good pollination conditions during the flowering period of cucumbers, such as bee feeding and artificial pollination. In addition, in the early stage of plant growth, the supply of nitrogen fertilizers is insufficient, making the plant stems thin and tough, and it also produces tipped melons. The control measures include the application of fertilizers with high nitrogen content such as urea. Second, Daduguagua. The main reasons for the formation are: 1. The insemination of female flowers in cucumber is incomplete. Only seeds are produced at the apex of the melon, which leads to a particularly enlarged pulp in the apex. Control measures to create a good flowering conditions. 2, plant potassium deficiency and excessive nitrogen fertilizer. Control measures include applying potassium nitrate, turfgrass, etc., or applying 0.3% potassium dihydrogen phosphate solution to spray the leaves of plants. 3, cucumber lack of water in the early growth, and a large number of water supply in the later period. Control measures provide a balanced supply of water throughout the growing season, keeping the soil wet. Third, bending melon. The main reasons for the formation are: 1. During the growth of cucumbers, the crooked melons are affected by factors such as high temperature, high humidity, and adverse weather. The prevention measures are to take a toothpick and tie it on the cucumber vines that produce the curved melon parts. After pouring water again, the melon strips can be straightened the next day. At this time, the fine toothpick will be pulled out and the cucumbers can still grow normally. 2, cucumber in the growth process, blocked by foreign objects and can not normally stretch, resulting in malformation bending. The prevention and control measures are cucumbers sitting on melons and removing foreign substances that block the growth of cucumbers so that the cucumbers can normally elongate. Fourth, the beak waist melon. The female flower of cucumber is not completely pollinated, and it easily develops into a beaked kidney melon. After the cucumber is pollinated, the nutrient supply in the plant is insufficient, dry matter accumulation is less, and it is easy to form bee loincloth. Prevention measures to strengthen nutrition, especially in the fruit setting period, to increase the supply of fertilizer and water, to ensure adequate accumulation of nutrients.
