In the summer and autumn seasons, when temperatures soar, it's not just humans who suffer from heat-related issues—crops are also vulnerable to "heat stroke," a condition known as high-temperature heat damage. This phenomenon can hinder crop growth, reduce yields, and even cause irreversible damage to plant organs. To mitigate these effects, several effective measures can be taken.
First, water cooling is one of the most common and effective methods. Timely irrigation helps lower the temperature in the field by 1–3°C, which can protect sensitive parts of the plant such as
Flowers And Leaves. For example, during the early rice filling stage, if temperatures reach around 35°C, immediate irrigation followed by night drainage can prevent "heat cooking" of the grains. Some regions use a method of watering in the morning, deep irrigation during the day, and evening drainage, which has proven more effective than single irrigation, reducing heat stress by 5.8–8.1%. Sprinkling water directly onto the stems and leaves of dry crops using sprayers or irrigation systems can also provide cooling, typically lowering temperatures by about 1°C.
Second, artificial pollination plays a crucial role during hot and dry periods. High temperatures often weaken natural pollination processes, especially in cross-pollinated crops like corn and sorghum. By manually assisting with pollination, farmers can significantly improve fertilization rates, increasing them by 5–8% compared to natural pollination.
Third, foliar feeding is another important strategy. During high temperatures, applying diluted solutions of urea, human or animal urine, potassium dihydrogen phosphate, or calcium superphosphate and ash leachings multiple times can help cool the plants while providing essential nutrients. However, it's important to adjust the concentration and increase water usage to avoid leaf burn.
Finally, proper agricultural management is key. Optimizing fertilizer application can enhance the plant’s resilience to heat stress. For instance, spraying sweet peppers with a 30 ppm chlorophenoxyacetic acid solution can help control flower drop caused by high temperatures. Tomatoes treated with B9 (2000–3000 ppm), zinc sulfate (0.1%), or copper sulfate solutions show improved heat resistance and better protection against cracking and sunburn. Using 2,4-D for fruiting can also help prevent blossom drop and promote ovary development. In vegetable farming, using shade nets or plastic greenhouses during the summer and autumn can reduce temperatures by up to 4–6°C, while also protecting crops from heavy rain, hail, and pests.
By implementing these strategies, farmers can effectively reduce the impact of high temperatures on their crops, ensuring better yields and healthier plants.

In 1892, French missionary father Tian Daneng preached in Dali, Yunnan Province, China. In order to drink coffee, he taught local villagers to grow and drink coffee. Up to now, coffee has been planted in Yunnan Province of China for more than 100 years, with an area of 120000 mu. Most of the varieties planted in Yunnan are ccatimor, with an altitude of 1000-1500m, The coffee produced in Yunnan has a balanced taste, rich nut and citrus flavor, some of which are very sweet, with obvious taste of chocolate, toffee and maple sugar. It is one of the high-quality coffee producing areas. Our coffee is produced at the junction of Puer and Burma - the Myitkyina original jungle beans at 1500-1750, with a rich flavor, high aroma and high sweetness. The 2019 international coffee cup Masters Tournament (China finals) is sponsored by beans.
