Tips for growing vegetables in high temperatures (countermeasures to the impact of high temperatures on vegetable growth)

We all know that high temperatures in summer have a great impact on crop planting, but in what specific aspects? It is believed that high temperatures in summer can cause several major harms to crops: drought and disease, so we need to deal with them from several aspects.

Take good measures to cool down and prevent heatstroke

Different crops have different requirements for temperature, but the reaction brought about by high temperature is the same, that is, water evaporates faster and crops grow faster. Therefore, the first thing to do at this time is to cool down and prevent heatstroke.

Pruning crop branches and leaves in time can speed up air circulation between crops, promote the upward growth of crops, and reduce the temperature in the park.

Secondly, for greenhouse growers, they should cover the greenhouse in time to avoid long-term direct sunlight which will cause the temperature inside the greenhouse to rise sharply. At the same time, they should spray water in time to keep the soil moist.

Because high temperature and strong light will cause the plants to lose water and wilt, affecting their growth. If the water supply does not keep up, the plants may die.

Clean up the park

Many people ignore the fact that summer is a season with a high incidence of diseases and insect pests, especially under high temperature and high humidity conditions, which can induce many diseases. Therefore, in addition to cooling down and preventing heatstroke, the park must also be managed well.

On the one hand, it is necessary to clean up the dead branches and fallen leaves in the park in time to reduce the spread of diseases and pests; on the other hand, it is necessary to do a good job in flood prevention to avoid root waterlogging and root rot caused by heavy rainfall.

Do a good job of fertilizing and topdressing

Summer is also the time when crops grow rapidly. At this time, don’t forget to apply fertilizer in time. Many people don’t understand why top dressing is needed at this time.

Because this is often the season for crop picking and ripening, topdressing can provide nutrients for fruit ripening and improve the quality of fruit trees.

On the other hand, timely topdressing can enhance the stress resistance of crops, avoid the emergence and spread of pests and diseases, and reduce the economic losses caused by pests and diseases in the park.

Finally, the management of vegetable plantations in summer must also focus on crop quality, soil fertility, etc. In addition to preventing high temperatures, we must also do a good job of preventing waterlogging and pests.
