Effect of Solar Indoor Wind Speed ​​on Plant Growth

The size of the wind speed in the solar greenhouse can directly regulate the indoor microclimate, such as reducing the temperature, removing moisture, increasing the CO2 content; the appropriate wind speed is also conducive to the photosynthetic, respiratory, and transpiration effects of the crop, and the detection of the wind speed in the greenhouse and the appropriate The regulation regulates the growth and development of plants. The wind speed in the greenhouse can be measured using a wind anemometer or wind anemometer.

Appropriate airflow velocity is conducive to the growth and development of crops, especially in the relatively closed microenvironment in the greenhouse effect is more significant. Through experiments, the optimum wind speed for the growth of muskmelon in the greenhouse is about 1.0 m.s-1, and no wind or too high wind speed is conducive to the growth of muskmelon. The appropriate wind speed is conducive to the increase of leaf area, the increase of leaf area index of the population, and can increase the photosynthetic rate of leaves, increase fruit yield and improve quality. In terms of the impact of wind speed on crop growth and development, scientists at home and abroad who have conducted experiments at the seedling stage have found that proper wind speed can make seedlings grow stronger and at the same time increase their survival rate. The survival of seedlings in an environment without wind-direction wind speed after the transplantation is relatively weak after the growth.

The wind anemometer avoids the low precision of traditional instruments for measuring the wind speed and cannot record continuously. The artificial influence on the measurement process is large. This wind anemometer has three measurement modes, manual automatic and computer-locked mode to measure, can be selected according to their own preferences, while the measurement accuracy is high, can continuously record multiple sets of data and has a preservation function. Like the computer lock mode of operation and the ability to process data: all the keys on the host failure (lock key), according to the computer set the interval automatically sampled to ensure the authenticity and continuity of the data. This avoids large errors due to data discontinuities. It is a good instrument for measuring wind speed.
