During summer cultivation, vegetables are exposed to high temperatures, strong sunlight, and intense evaporation, with minimal day-night temperature differences. This can lead to imbalances in vegetative and reproductive growth, weak flower bud differentiation, poor fruit development, and challenges with fruit setting. In greenhouses, temperatures can exceed 40°C
During the growth period, vegetables for summer cultivation are in an environment with high temperature, strong light, high evaporation, and small temperature difference between day and night. At this time, the respiratory metabolism is strong, and it is easy to have problems such as nutrient growth and reproductive growth imbalance, weak flower bud differentiation, poor fruit development, and difficulty in fruit setting.
In the greenhouse, the high temperature and strong light, above 40℃, and even the ground temperature may be high, which is not conducive to the growth of the root system. After many roots are pulled out, there may not be enough capillary roots, and the main root is not inserted deep. For example, in the case of cucumbers, there will be many spring roots, which grow in circles. These situations are all issues to be considered for summer cultivation.
Therefore, the first thing to do for summer cultivation is to maintain the root system. For root maintenance, I remind you that you can choose a fertilizer that can be applied to nourish the roots, such as humic acid, amino acids, seaweed fertilizer, chitin, and biological bacteria. If you encounter particularly harsh environmental conditions, such as severe damage or harm to the root system, you can use a special rooting agent for flushing. But don't become dependent on it. We should try to use root and soil nourishing products to nourish the root system.
In the hot season, crops may grow vigorously, so when watering and fertilizing, water frequently and adjust the growth of plants.
If you want the plants to grow fast, use balanced or high-nitrogen products. If you don't want them to grow fast, you can choose high-phosphorus products if you have the conditions, or use some growth-regulating products, including potassium dihydrogen phosphate, and products such as growth enhancer and dwarfing. When you use these products, the first time should be light, and the second time can be slightly heavier. It is very important to regulate the growth and supplement sufficient nutrition.

In addition, during field management, the weather is hot and insect pests will cause more harm, so early prevention is necessary.
It is recommended that you use insect-proof nets, and all insect pest agents can be sprayed. However, avoid the hottest sunny days and the hottest time periods to avoid pesticide damage, and be sure to take precautions in advance. At this time, the normal growth of crops can be guaranteed, allowing vegetables to safely survive the summer.
