Autumn cucumbers are generally planted in July, and can be harvested by the end of October. The yield per mu can exceed 10,000 kg, and the economic benefits are considerable. The main reason for planting good autumn cucumbers is as follows: First, the selection of good varieties At present, the autumn cucumber variety is mainly Zhongnong No.8, the variety of this variety is high, the yield per mu is over 10,000 kg, and the commodity is good. In addition, Jinqing No. 4 and Jinyou No. 4 are also suitable for autumn cucumber cultivation. Second, timely seeding Autumn cucumber sowing period It is suitable for mid-July, and the flowering result period is after mid-August, and the temperature difference between day and night is gradually increased, which is beneficial to the growth of cucumber and high yield. The seeding method can be carried out by seed. Third, Shi foot base fertilizer Autumn cucumber should be planted in the sandy loam field where fertilizer, water retention and irrigation are convenient. Before planting, the farmer applied more than 1,500 kilograms of farmer's soil and ploughed into the soil. After using 45% of the 45% compound fertilizer , the seeds can not be contacted with the compound fertilizer. The width is 1.4 meters, two rows are planted, and the plant spacing is about 30 centimeters. Two seeds per sowing, the soil is 0.5 cm. Four or four management After emergence, the surface can be sprayed with 40% chlorpyrifos 150 ml to prevent the tiger from harming. In the 2~4 leaf stage of the seedlings, four strains of ethephon solution were sprayed every four plants to promote the increase of the number of female flowers. At the 4th leaf stage, the seedlings are planted, and each plant is planted in a timely manner. After the first batch of cucumbers were harvested, 30 kg of urea per mu was applied. In case of drought, it should be timely flooded, and irrigation should be carried out in the middle of the night. It is forbidden to irrigate at noon high temperature to prevent dead seedlings. Five, disease prevention and control Prevention of pests and diseases should be carried out before cucumber harvesting. The disease can be treated with 58% metalaxyl manganese zinc, 50% nail cream copper, 10% guaran 500 times liquid; insect pests can be controlled by 10% imidacloprid, 40% chlorpyrifos 800 times liquid and other pollution-free pesticides. No pesticides can be used after cucumber is picked.
