1. Chemical incremental method. When cucumber grows 1 to 3 true leaves, the flower buds of the leaf axils of the second to the 21st node will gradually differentiate, but it has not been determined whether it is a female or male flower. At this time, spraying ethephon is the best time. The spraying concentration of ethephon is generally 100~200 mg/L. If it is sprayed twice, 200 mg/L is effective; sprayed 3 times, 100 mg/L is effective, just spray 1-2 times. When spraying, use a sprayer to spray the front and back of the leaves at 4 pm on a sunny day.
2. Shading to control light. Cucumber is a short-day crop, and artificially shortening the light can increase the number of female flowers. Before cucumber flowers are formed, in summer, the use of black shading nets with lower shading rate can reduce the average daily temperature of the cultivation bed by 1.4℃, the average ground temperature of 5 cm by 2.1℃, and the average light intensity by 66.2%, reducing the daily sunshine hours Control within 9 hours.
3. Increase moisture and nitrogen fertilizer. The yield of cucumber planted in soil with 80% humidity is more than twice that of planting in soil with 40% humidity. It is necessary to ensure that the cucumber has sufficient water conditions, irrigate in time, and maintain a moist environment. In the early growth and development of cucumber, if sufficient nitrogen fertilizer is ensured, the number of female flowers can also be increased.
