Has the effect of plant growth regulator characteristics: ① the role of a wide range of application areas and more. Plant growth regulators applied to contain virtually all the higher and lower plants planting foliar series, such as field crops, vegetables, fruit, flowers, trees, kelp, seaweed, mushroom, etc., and by regulating plant photosynthesis, respiration, physical absorption and operation, signal transduction, stomatal opening and closing, osmotic regulation, regulation of physiological processes such as transpiration and control of plant growth and development, improving the interaction between plants and the environment, and enhance the resilience of crops, increase crop yields and improve the quality of agricultural agent fertilizer, crop agronomic traits by people expressing needs 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. Yemianpenfei usually valid only for 12 to 15 days, to be continuously for more than 2 or 3 times foliar spraying will affect the long-term root growth, impair physiological functions of root, it should be on the basis of soil fertilization, the foliar spray fat as a rapid nutrition and supplementary measures to apply.
