There are ways to increase cucumber production in summer

1. When spraying ethephon cucumber to grow 1 to 3 true leaves, the flower buds of leaves 2 to 21 are gradually differentiated. When the female flower or male flower has not yet been differentiated, spraying ethephon can increase the amount of female flowers. The concentration of ethephon sprayed was 100-200 ppm. Spraying 1 to 2 times, when sprayed, it is best to select it at 4 o'clock in the sunny afternoon. It is necessary to spray the front and back of the blade, and spray after spraying should be sprayed. In the middle and late stages of cucumber growth, it can be sprayed 3 to 5 times with 0.3% potassium dihydrogen phosphate and 3000 to 4000 times 802 mixture to prevent premature aging.

2, shade control light method cucumber is short-day crops, artificially shortened light can increase the number of female flowers. Before the formation of cucumber flowers, a black shading net with low light transmittance was used to cover. The daily average temperature of the cultivated bed could be reduced by 1.4°C, the average temperature of the 5cm can be lowered by 2.1°C, and the light intensity can be reduced by 66.2% on average. The daily sunshine time can be controlled at 9 Within a few hours, there are no shade nets, and shades can be used on the scaffolds with straws, black paper, etc.

3. Increasing the water and fertilizer method The cucumber seed is more than 1 times higher in the soil with a humidity of 80% than in a soil with a humidity of 40%. Therefore, it is necessary to ensure that the cucumber has sufficient water during the growth process, so that it can be poured in time. Water, maintain a moist environment. In addition, in the early growth and development of cucumber, the supply of sufficient amount of nitrogen fertilizer can also increase the number of female flower differentiation, but also to strengthen the prevention and treatment of pests and diseases.
