Causes and Control methods of low yield of Cucumber in Autumn

After the beginning of autumn, although the temperature was still a little high, it began to slowly enter autumn. Autumn was the harvest season and a good time for vegetable planting. Cucumber is one of them, its growth cycle is relatively short, soon after planting can be sold on the market, but many growers autumn cucumber yield is extremely low, what is the reason for this? Let's learn about it together with Xiaobian.

1. Variety degradation

If long-term single cultivation of a cucumber variety, it will inevitably lead to its variety degradation, resulting in yield and quality in summer, which is inevitable. Another point is to keep seeds. When planting, we must pay attention to the method, which may also cause variety degradation. In addition, some farmers who like to follow the trend should see whether the local environment is planted or not, otherwise the yield is extremely low.

Solution: To select seeds reasonably, it is necessary to select suitable varieties according to the local climate environment, and at the same time, it is also necessary to combine factors such as market demand. It is recommended to select short-day varieties with early heat resistance, late cold resistance and high pest resistance.

2. Wangchang

A phenomenon that occurs in the growth process of many vegetables during vigorous growth, mainly caused by excessive application of nitrogen fertilizer or unreasonable planting density by farmers in the planting process, which will lead to the reduction of flower bud differentiation, easy drop of flower buds, unfavorable root growth and development, and low yield of cucumber.

Solution: According to the plant quality of cucumber, reasonably grasp the plant density, if it is greenhouse cultivation, but also pay attention to ventilation, if there is vigorous growth, you can use chemicals to control flourishing, when cucumber grows to three to four true leaves, spray 1200 times of ethephon ripening agent, can play a role in inhibiting excessive growth of melon seedlings and increasing female flowers.

3. Serious diseases and insect pests

Pests and diseases are an environment that crops are afraid of. A little carelessness will lead to the death of large areas of crops. Autumn cucumbers grow in high temperature and rainy seasons, so special attention should be paid to the invasion of pests and diseases. In addition, many pests and diseases will also cause the reduction of autumn cucumbers.

Prevention and control methods: pest outbreak should be based on prevention, common diseases are epidemic disease, gray mold, downy mildew, etc., when it occurs, it should be sprayed in time to prevent and control, serious diseases should be removed in time, and concentrated destruction. Common pests are aphids, thrips, whitefly, etc., can be hung in the field yellow plate catch insects, or use chemical insecticides, can choose 10% imidacloprid spraying.

The above is an introduction to the reasons for low yield and control methods of autumn cucumber. I hope it can help you. If you want to know more about it, please pay attention to us.
