How to grow cucumbers in summer and autumn? Please guide that spring cucumbers planted in some places are generally ordered from late June to early and mid-July, while the cultivation of cucumbers in summer and autumn just makes up for the supply of cucumbers in the market from mid-to-late July to early and mid-December, so they are deeply welcomed by the public and vegetable farmers have better economic benefits. in order to plant summer and autumn cucumbers, we must grasp the following links: 1. Select appropriate cucumber varieties. If the variety is not selected properly, the yield will be seriously affected. During summer and autumn, the temperature is high and there are many diseases and insect pests, so it is appropriate to choose varieties that are heat-resistant and disease-resistant. Because of the long sunshine in summer, when cucumber is cultivated under long sunshine, it is necessary to select varieties that are not sensitive to light, so as not to reduce the female flowers and reduce the yield. Cucumber is a short-day vegetable. In general, spring cucumber varieties can promote the formation of female flowers under the condition of short sunshine in spring, but if sowing in summer and autumn, under the environment of long sunshine, there will be luxuriant branches and leaves, less female flowers and more male flowers. The phenomenon that only blossoms but does not bear melons. Therefore, the general spring cucumber varieties are not suitable for summer and autumn cucumber cultivation, for this reason, summer and autumn cucumbers in Shanghai generally choose Jinyan system type cucumbers, such as cool summer cucumbers, Lvmei or Jinza No. 2, autumn cucumbers can choose Jinyan cucumbers, long type Nitraria, the Beginning of Autumn fall, and so on. 2. sow seeds at the right time. Summer cucumbers are generally sown in batches from mid-June to late June, autumn cucumbers are generally sown in early July, sowing in batches, and can be sowed until August, if the tube shed cucumbers can be sowed until late August to early September. 3. It is cultivated in protected areas such as pipe shed. The temperature in summer and autumn in Shanghai is high, there are many rainstorms and typhoons, and natural disasters are frequent. In order to ensure a high yield and bumper harvest of cucumber in summer and autumn, seedlings should be planted not only in plastic pipe shed, but also in pipe shed, covered with plastic film and well covered with sunshade net in seedling stage to improve seedling quality and lay a good foundation for high yield and high quality. 4. Strengthen the management of fertilizer and water. Because the summer and autumn cucumbers in the tube shed can not be drenched by Rain Water, the temperature is high at this time, the cucumber transpiration is exuberant, and a lot of water is needed, so it is necessary to strengthen fertilizer and water management and carry out furrow irrigation if necessary, but avoid full border flooding irrigation and drain stagnant water in time after furrow irrigation at night. Fertilizer should be applied in the harvest stage, and the method of "eating less and eating more" should be adopted, that is, the number of times of topdressing can be more, but the concentration should be lighter, and the amount of fertilizer applied each time is less, which is beneficial to the absorption of cucumber. 5. Prevent diseases and insects. The main diseases and insect pests that endanger cucumber in summer and autumn are Fusarium wilt, powdery mildew and aphids, so it is necessary to strengthen control, give priority to prevention, and use the same pesticides as spring cucumbers, so as to ensure the healthy growth of plants and improve yield, quality and economic benefits.
