The latest cucumber tip rot causes and control methods

Cucumber is cultivated in greenhouse in winter and spring, especially in winter, because of the low temperature, the absorption capacity of cucumber root system is weakened, and the problem of rotting tip is very easy to occur, which seriously hinders the production of cucumber. So what happened to the rotten tip of the cucumber? Is there any way to solve it? Let's get to know it with the editor.

First, the reason for the rotten tip of cucumber

There are many reasons for cucumber rot, most of which are caused by improper management and diseases, among which the management methods include high planting density, continuous cropping for many years, partial application of nitrogen fertilizer, insufficient maturity of organic fertilizer, poor ventilation, high humidity, poor drainage, lack of light and so on. The main diseases are scab, vine blight, bacterial edge blight, their symptoms are different, but they all have one thing in common, that is, they will cause cucumber rot. Therefore, for the causes of rotten tip of cucumber, we should take targeted control measures to promote the healthy growth of cucumber and improve the yield and quality.

II. Prevention and control methods

1. Protect and strengthen the seedlings

After the cucumber seedlings are planted, the new high-fat membrane should be sprayed in time, which can effectively prevent the aboveground water from evaporating, the seedling water will not transpirate, isolate the harm of diseases and insect pests, shorten the slow seedling stage, and promote the seedlings to be strong. After slowing down the seedlings, the measures of temperature control and water control can be taken to promote the root system to tie down, enhance the root absorption capacity and cultivate strong seedlings.

2. Paddle hoe

After buckling the film, you can lift both sides of the plastic film near the main stem, and then draw a hoe many times in the shed. The hoe is from shallow to deep, and the shallow root system should be cut off consciously to promote its deep penetration. Enhance the absorption of roots and the cold resistance of plants. If you hoe deeply at the beginning, it will hurt the root system, not only will not cause the root system to root down, but may also cause plant death.

3. Spraying

In the initial treatment of cucumber rotten tip, while spraying growth regulators and nutrient solution, some pesticide fungicides and new high-fat membrane should be added to prevent bacteria from invading directly from the wound and causing greater losses due to the spread of bacteria.

4. Root irrigation with micro-fertilizer

Timely irrigation with root application and micro-fertilizer can induce plants to absorb, digest and release nitrogen, phosphorus, potassium and various trace elements in soil, improve the positive energy of fruit development and improve the ability of freezing resistance.

The above is the introduction of the causes and control methods of cucumber rot. I hope it can help you. If you want to know more about it, please follow us.
