Summer and autumn cucumbers have high temperature, effective accumulated temperature, rapid growth and development, and short fruiting period during the growth period, resulting in low yield and poor efficiency of cucumbers in summer and autumn. To increase the yield of summer and autumn cucumbers, there are several points in cultivation:
1. Select suitable and excellent varieties. Choose varieties with high disease resistance, good heat resistance, strong growth potential, multiple branches, and sitting late in melons, such as Xiafeng 1, Jinyan 6, Jinyan 7, and Xiong 58.

2, a reasonable fertilization. Summer cucumber cucumber melon peak in late summer, in order to provide a reasonable supply of nutrients, the previous Mushi cake fertilizer 75 kg, 20 kg of phosphate fertilizer. Combination of watering during growth, interval fertilizer once fertilizer, Mu recovery urea 10-12.5 kg. Top dressing depends on the seedling condition, weather, and soil quality, and less applied to the ground. Nitrogen, phosphorus and potassium are mixed in, and the leaves can be sprayed with trace elements such as calcium, magnesium, and copper.
3, change the cultivation style. Narrow sorghum cultivation is mainly used to facilitate water drainage. The width is 40-50cm and the height is 5-8cm.
4, spraying ethephon for treatment. Summer and autumn cucumber growth period is the high temperature and rainy season, whether live or nursery cultivation, hormone treatment should be in front of cucumber 1-3 leaves. The method is: 40% ethephon agent 5ml watered 20 kilograms, sprayed on the whole plant after 4 o'clock on sunny days.
