Cucumbers producing short fruit affects their market appeal; how can this be prevented and controlled?

    When cucumbers produce short fruit, it affects their market appeal. So how should short fruit in cucumbers be prevented and controlled? Green Food Network summarizes and analyzes the causes of short fruit in cucumbers and the corresponding solutions as follows:

Cucumber

    Improper node position for fruit retention:If the node position for retaining the first fruit on the lower part of the cucumber plant is too low, the cucumber will not grow long. The best position for retaining the first cucumber fruit is near the seventh leaf. If the fruit is retained too early, the cucumbers at the bottom are prone to growing into short fruit.

    Solutions:Retain fruit at the appropriate node position, and the root fruit should be removed at the right time.

    Root damage:If the root system is too shallow, or the roots are damaged and grow poorly, the fruit will also struggle to grow large. When the weather is sunny, water evaporates quickly in the greenhouse, and watering too frequently prevents the cucumber roots from growing deep, which affects the expansion of the cucumber fruit; after cucumbers are transplanted, covering with plastic film too early also prevents the roots from growing deep and can easily lead to short fruit. In addition, applying too much compound fertilizer or improper farming operations can cause root burn and root damage in cucumbers, so the roots cannot absorb enough nutrients to supply fruit growth, which also prevents the fruit from growing long.

    Solutions:Control the frequency of watering to promote deep root growth. When the weather is sunny, it is advisable to water cucumbers once every 12-15 days. Combined with the application of root-growing and root-protecting fertilizers, increase the application of biological bacterial fertilizer to improve the rhizosphere environment, promote the damaged roots to grow new roots as quickly as possible, and deliver nutrients to the fruit.

    Excessive application of inhibitors:In the early stage of cucumber growth, greenhouse temperatures are high and prices are low. To delay the cucumber harvest time, many vegetable growers apply large amounts of growth inhibitors, such as paclobutrazol and high concentrations of atonik, to inhibit plant growth. As a result, because of excessive inhibitor application, the cucumbers become short and thick.

    Solutions:Spray regulators that promote plant growth to help the cucumbers recover their growth as quickly as possible.
