Because if it is later, the temperature will be lower and the survival rate of cucumber will be low. Plant it in August at the latest. Before the cucumber seeds are unearthed, the temperature should be controlled at about 25-30℃, and the temperature at night should be kept at about 16-20℃ as far as possible. The whole growth period of cucumber takes 80-90 days. If it is planted too late, the yield of cucumber will be affected by natural disasters such as cooling and frost in the fruiting period, and even the harvest will fail, which will not only waste human and financial resources, but also lose one crop.

Planting can be done by raising seedlings first or directly. Because of the high temperature in summer and fast germination, it can be planted directly. Apply base fertilizer before planting, and then prepare the soil. Generally, the base fertilizer is mainly fully decomposed farmyard manure. After applying base fertilizer, deeply plough the soil to make a border. The frame is10cm high, 60cm wide and 70cm wide. Planting two rows in the border, sowing 2-3 seeds in each hole, and covering the soil with a thickness of 65438.

Pest control of autumn cucumber

Autumn cucumber is susceptible to downy mildew, epidemic disease, aphids, thrips and other diseases and insect pests. Implement the policy of combining prevention with control, eliminate the root causes of diseases and pests through physical and chemical prevention, and prevent the spread of germs. In the early stage of pest occurrence, early detection and early control should be achieved. It should be noted that don't spray any pesticides after picking cucumbers.

On the one hand, autumn cucumber planting should pay attention to variety selection, on the other hand, it should pay more attention to pest control, because August is the hottest time and the period of high incidence of pests and diseases, and it is even more troublesome to plant autumn cucumber at this time.
