Causes and Control methods of low yield of Autumn Cucumber

After the Beginning of Autumn, although the temperature is still a little high, but also slowly began to enter the autumn, autumn is not only the harvest season, but also a good time for vegetable cultivation. Cucumber is one of them, its growth cycle is relatively short, it can be sold on the market soon after planting, but the yield of autumn cucumber of many growers is very low, what is the reason for this? Let's get to know it with the editor.

1. Variety degradation

If a single cucumber variety is planted for a long time, it is bound to lead to the degradation of the cucumber variety, resulting in summer yield and quality, which is inevitable. Another point is to keep your own seeds, and you must pay attention to the methods when planting, which may also lead to the degradation of varieties. Other farmers who like to follow the trend depend on whether they are planted in the local environment, otherwise the yield is also very low.

The solution: to select seeds reasonably, to select suitable varieties according to the local climate and environment, and to combine the market demand and other factors, it is suggested to select short-day varieties with heat resistance in the early stage, cold resistance in the later stage and high resistance to diseases and insect pests.

2. Flourish and grow

A phenomenon that occurs during the growth of many vegetables is mainly caused by excessive application of nitrogen fertilizer or unreasonable planting density in the process of growing. These will lead to the reduction of flower bud differentiation, flower buds easy to fall, root growth and development, low yield and other problems.

Solution: it is necessary to reasonably grasp the plant density according to the plant quality of cucumber, and if it is cultivated in the greenhouse, we should also pay attention to ventilation. If there is vigorous growth, chemicals can be used to control the growth of cucumber. Spraying 1200 times ethephon ripening agent can inhibit the growth of melon seedlings and increase the number of female flowers.

3. Serious diseases and insect pests

Diseases and insect pests are an environment that crops are afraid of. A little carelessness can lead to the death of a large area of crops. Autumn cucumbers should pay special attention to the invasion of diseases and insect pests because they grow in the high-temperature and rainy season. In addition, many diseases and insect pests will also cause the reduction of autumn cucumbers.

Prevention and control methods: the occurrence of diseases and insect pests should be based on prevention, and the common diseases are blight, gray mildew, downy mildew and so on. when they occur, they should be sprayed in time to prevent and cure, and the more serious diseases should be removed in time and destroyed. Common pests are aphids, thrips, Bemisia Tabaci, etc., you can hang the yellow board in the field to catch insects, or use chemicals to kill insects, you can choose 10% imidacloprid spray.
