Light Quantum Meters Help Improve Plant Utilization of Light Energy

Illumination is very important for plants, and its effect on plants is to use light energy to convert inorganic matter into organic matter, which is needed for its own growth, that is, the photosynthesis of plants. Photosynthesis of plants is its most important physiological activity, and it is a process of all organic matter. Therefore, if sufficient sunlight can be provided at the stage where plants need sunlight, the growth and yield of plants will be greatly promoted. Plants grow well and the plants must make full use of the light to produce more organic matter. By using an optical quantum meter to measure the light intensity of the crop environment, and to appropriately adjust the plant's demand, the effect of increasing production can be achieved. The method of photoquantification has been experimentally verified and can promote the growth of plants.

Carnation is an evergreen subshrub of the family Caryophyllaceae. It is like sunshine, high dryness, ventilation, cool and dry environment. Its stems and leaves are delicate, the flowers are graceful, beautiful and aromatic, with high ornamental value, long single flowering period, resistant to bottle insertion. It is mainly used for cutting flowers and is one of the traditional four fresh cut flowers. What about the demand for light intensity in carnations? By using a photosynthetic active radiometer to control the growth environment of a carnation, the need for light intensity is understood. Through the analysis of photosynthetically active radiometers, the demand for light intensity of carnations in different growth practices is different. In the early stage of vegetative growth of carnations, strong illumination must be given. If necessary, electric illumination can be increased, which is beneficial to plants. Robust growth enhances the lodging resistance of the plant during late vegetative growth. In the late and late stages of vegetative growth, strong light favors the emergence of lateral buds. Light intensity is one aspect. In addition, rainfall is also a factor that affects the use of light energy in carnations. Rainfall can be measured by a rain recorder.

The light intensity also affected the growth of plants with carnations. With the decrease of the light intensity, the carnation plants became shorter, the number of lateral buds was less and less, and the plants were thinner and thinner, and the leaf width was reduced. Loss of lodging resistance. Therefore, for the carnation to have this robust plant, as well as the beautiful flowers, it is necessary to use the light quantum meter for detection and control during the growth process. Quantum photometers are now widely used in agricultural and forestry research and production departments for the measurement of photosynthetically active radiation.
