First, there is a clear principle of foliar leaf structure, the basic structure of the leaf blades, petioles, stipules. Leaves also includes epidermis, mesophyll, veins. Mesophyll generally divided into palisade and spongy tissue (that C3 plants and C4 plants are different). Has the effect of plant growth regulator characteristics: ① the role of a wide range of foliar series, applications and more. Plant growth regulators applied to contain virtually all the higher and lower plants farming, such as field crops, vegetables, fruit, flowers, trees, kelp, seaweed, mushroom, and through the regulation of plant photosynthesis, respiration, material to absorb and operate, signal transduction, stomatal opening and closing, osmotic regulation, regulation of physiological processes such as transpiration and control of plant growth and development of foliar fertilizer prices, and improve the interaction between plants and their environment fertilizer, enhance crop resistance inverse ability to improve crop yields foliar company, improve quality of agricultural products, according to the crop to express agronomic traits people need direction. ② the amount of small, fast, high efficiency, less residues. ③ can be internal to external traits and physiological processes of plants double regulation. ④ targeted, professional and strong. Some other means to resolve difficult issues, such as the formation of seedless fruit, control winds, control the plant type, promote ROOTING, fruit ripening and coloring, inhibit axillary bud growth, promote cotton leaf shedding. ⑤ use of plant growth regulators effect is affected by many factors, but it is difficult to achieve the best. Weather conditions, time of application, absorption dosage, application methods, application site and crop itself, running, integration and so on will affect their metabolic effects.
