Pepper hanging sticks are used to prevent the branches from falling and breaking, thereby increasing the yield and improving the quality. For this agricultural operation, many vegetable farmers are very casual in timing and think that they can do it all at the time. The author found in the production practice: After 3 o'clock in the afternoon, it is better to hang the peppers.
After a night's breathing, the peppers have a high concentration of carbon dioxide in the shed, and the current light intensity and temperature are appropriate. Therefore, the morning is the main time for the photosynthesis of the pepper leaves. The amount of photosynthesis can account for the amount of photosynthesis in the whole day. 70%~80%. If hanging sticks are taken in the morning, the pepper leaves will change their original angle, which will reduce the area of ​​light exposure, which will affect the photosynthesis of the leaves. If the leaves turn back to the original angle for a long time, they will miss the best photosynthesis. Time is not conducive to the improvement of pepper production.
After 3 pm, with the decrease of the light intensity, the increase of ventilation, the decrease of carbon dioxide, the photosynthetic rate of the pepper leaves decreased, and the light and the product were less. After 3 o'clock, the hanging branch had little effect on the photosynthesis of the pepper, and The petiole of the pepper leaves can be turned back to its original angle in the afternoon and evening hours without affecting the photosynthesis of the leaves the next day. At the same time, pepper sticks are softer than the morning after 3pm, and they are not easily damaged when hanging branches. When suspending the branch, the lifting rope can be 25 centimeters away from the growth point of the pepper, so that the growth point of the pepper can be grown obliquely upward instead of vertically, so that the leaves do not block each other, which is beneficial to increase the light-receiving area of ​​the leaf. Promote the vegetative growth of peppers and increase yield.
