Correctly look at the effect of light on crop roots
In the growth and development of crops, light is an important influencing factor. In the past, the effect of light on the roots of crops was relatively shallow, and there was a lack of insight into the essential role of light in the growth and development of crops. The mechanism of action of light is still unclear, and some theoretical and practical issues remain unresolved. With the continuous improvement of research methods, the research on the relationship between light and crop roots is bound to gradually deepen. 1) The direct effect of light on crop roots The predecessors only focused on the direct and indirect effects of different light levels, light hours, and light quality on crop roots. With the deep understanding of all light, the author believes that the role of invisible light such as infrared spectroscopy is not necessarily completely confined to the traditional concept of heating the soil, but its radiation sterilization effect, the profound impact on the crop root morphology and physiology , are for further study. 2) Study on the effect of light waves on crop roots The effect of sound waves on the crop's shoots has been studied for a long time, but the influence of light waves on the root system has not been reported so far. What form of wave has effect on crop roots, what effect the wave has on the root system and how much influence it has, how light (a particular kind of wave) influences the root system development of the crop, and the effect of other forms of waves (such as electromagnetic waves) on the root system. What is the difference with light waves, etc., are all frontier issues that require urgent research. 3) The establishment of an optimal model for the effect of light on crop roots In recent years, research on constructing optimal plant types for crops has been extensive and in-depth. When wheat, corn, rice, cotton and other crops establish the optimal plant type, more consideration is given to the distribution of light in the field, and little attention can be paid to the distribution of light in the root environment. However, when establishing the optimal crop type, it is necessary to consider the effect of light on the root system, such as the effect of light on the differentiation and development of crop roots and their branches, complete darkness and different light levels, and different light quality on the morphology of crop roots. The influence of the structure, the effect of light on the formation and conduction of relevant active substances in the roots of crops, the reception, identification, transmission, and response of crop roots to light signals. Fully researching the optimum model of crop roots can provide a theoretical basis and technical support for establishing a reasonable plant type and population and realizing high yield and quality of crops.
