A Summary of the Latest Precautions for Pruning and Sucker Removal in Vegetables
In the era when greenhouse vegetables are popular, more and more growers are now carrying out greenhouse operations, and greenhouse vegetables also have their drawbacks: when crops are planted too densely, they are highly susceptible to pests and diseases. Therefore, timely pruning and sucker removal are needed to ensure good air permeability, and there are also some points to note when pruning and removing suckers from vegetables. Let's take a look together.
1. Avoid pruning and sucker removal on cloudy days
Vegetable pruning should be done on sunny days; sucker removal on sunny days helps wounds heal. If pruning and sucker removal are done on cloudy or rainy days, the wounds are difficult to heal, and pathogens will take the opportunity to invade, entering the stems through the wounds and causing stem rot to occur on a large scale. Each time you remove suckers, choose around 12 noon on a sunny day. Do not remove suckers in the early morning when there is heavy dew, so as to avoid wound infection and disease, and do not remove suckers in the evening, so as to avoid wounds being unable to heal, and because humidity is high at night, it is extremely easy to contract disease. Before removing suckers, pay attention to the weather forecast and leave enough time for wounds to heal.
2. Do not prune or remove suckers within 1-2 days of watering
After vegetables are watered, the plants have a relatively high water content at this time. If pruning and sucker removal are carried out, the wounds will be relatively large and not easy to heal. Therefore, pruning and sucker removal should be carried out on a sunny morning 2-3 days after watering, and pruning and sucker removal must not be carried out within one to two days of watering.
3. Sucker removal during the fruiting period
In the early fruiting stage of vegetables, try not to remove all the large suckers; for a period they form a certain leaf and branch area, which is what promotes root development and plant growth, and flower bud differentiation will also be better. If suckers are removed too early, the fruit on the first cluster will not grow large, and green-shouldered fruit, premature plant senescence and other conditions are extremely likely to occur, which will have a serious impact on yield and quality.
4. Prevent pests and diseases
After pruning and sucker removal, various wounds, large and small, will appear on the plants. In a greenhouse environment, the air does not circulate, which gives pathogens an opportunity to invade.
