The effect of temperature: flower bud formation and development of suitable temperature is 20 ~ 25 °C, higher than 27 °C or less than 15 °C prone to incomplete flower. Above 30°C, pollen increase, poor fertilization, this is an important reason for falling flowers; below 15°C, pollen formation is low, germination rate is low, and it is not conducive to fertilization and flowering. The temperature in the environment can still be properly regulated. It is necessary to understand the temperature change before the regulation, in order to carry out accurate regulation, temperature detection can use the temperature and humidity monitor to operate, it can be the temperature and humidity in the environment Real-time monitoring.
The effect of humidity: The suitable relative humidity for pollen germination is about 80%. When it is too dry, pollen cannot germinate. The stigma of pistil has poor adhesion, which is bad for pollination. When it is too wet, pollen does not rupture normally and the adhesion concentration of pistil stigma decreases. Good for fertilization. The humidity level directly affects the pollination problem. Therefore, the humidity control during this period is particularly important. The humidity level can be directly used by the temperature and humidity monitor to operate. After understanding, the appropriate increase or decrease of the humidity in the environment can be used. To promote the normal pollination of cowpea pollen.
Illumination effects: lack of light, decreased photosynthetic intensity, reduced assimilation, impaired plant growth, increased latent buds, serious flowering, lack of light in the natural environment to change, but in the greenhouse can be very quickly changed The use of photosynthetically active radiometers or photon quantifiers to measure the intensity of lateral illumination, and to control them by understanding their optimal light compensation points, can only regulate the structure of plants and change the light of plants. Irradiation area, measures taken in greenhouses and greenhouses will not be introduced one by one.
How to avoid the phenomenon of falling and falling of kidney beans
How to avoid the phenomenon of falling beans and falling beans Cowpea is a common dish on the table. In the process of planting kidney beans, the phenomenon of falling and falling out of cowpea is widespread and serious, which restricts the increase of yield and efficiency. The main reason for this problem is the temperature and humidity in the environment and the light intensity.
