JN-EP84 เรื่องยากแต่อยากให้รู้: สภาพอากาศ และค่า VPD ชาวสวนต้องใส่ใจ ปรับการให้น้ำตามสภาพอากาศ

Difficult but a learning experience: Weather and VPD values. Gardeners must pay attention and adjust watering according to the weather. Difficult but a learning experience. If you want to understand plants and the changing weather conditions, durian farmers must pay attention to VPD values ​​and adjust watering accordingly. Many egg-laying chicken farmers know that eggs tend to be small in the summer because the hens eat less. A female zoology friend of the guard explained that stress from the weather affects hens' body processes, and you can tell by observing their behavior. Plants like durians are also stressed. It's called environmental stress. Too hot or too cold, for example, flowers fall off. Too cold, leaves fall off. Plant physiologists have all studied this. This year, many gardens we visited, both in the video and in the non-video, experienced difficulty flowering and stunted flowering. This is because weather stress disrupts normal plant processes. For example, when the weather is hot, plants close their stomata to reduce excessive water loss. However, this behavior also affects flowering and fruit production. When plant processes are abnormal, what should happen doesn't happen. This is the nature of plants, responding to stimuli such as heat and dryness. What's difficult to explain is the difference in leaf pressure compared to the pressure in the air. Plant physiologists and physicists have used a formula to explain how when atmospheric pressure changes, the plant's transpiration rate changes, affecting respiration and photosynthesis, and ultimately, the tree's processes. The result is that when the weather is too hot, the flowers will fall and the flowers will turn red. When the weather is too cold, the leaves will fall, because the tree's processes are affected. The solution to climate change can be achieved by manipulating the climate in the garden, a process known as microclimate control. Many methods can be used to adjust the climate in the garden, such as increasing humidity, watering at the right time, or changing sprinkler heads. Another approach is to intercrop, planting plants around the garden as a buffer, absorbing excess heat, or releasing moisture for the durian trees. These are difficult and challenging to visualize, but we can't study and learn together. Let's learn together. A difficult lesson, but we can't learn it without learning it. It's like a subject with a builder: you have to learn this first before you can move on to the next. The next subject, after this course, is understanding what VPD is? Designing a garden watering system. Climate change. Durian trees are difficult to flower. Gardeners need to pay attention to VPD values. Adjusting watering according to weather conditions.
