Plant growth regulators have important functions such as regulating the growth of flower plants, preventing leggy, promoting rooting, cultivating strong seedlings, controlling sex differentiation, preventing flowering and falling fruit, enhancing resistance, and keeping freshness. However, different plant growth regulators are different in their methods of use, depending on the type of pesticide, the application target, the purpose of use, the growth status of the plants, and the climatic conditions. Therefore, reasonable selection should be made in practice. Seed dressing method and seed coating method are mainly used for seed treatment. When the seeds are treated with fungicides, insecticides, trace fertilizers, etc., plant growth regulators may be appropriately added. The method of seed dressing is to mix the medicine and the seed and mix it, so that the seed surface is stained with the medicine, such as spraying the medicine onto the seed with a sprayer, and stirring evenly to sow. Seed coating method is a special type of seed coating agent, wrapped in the outside of the seed, the formation of a certain thickness of the film, in addition to the promotion of seed germination, but also to achieve control of pests and diseases, increase mineral nutrients, regulate plant growth purposes . Immersion method is often used to promote cutting rooting, seed treatment, storage and preservation, such as the woody cuttings with leaves, placed in 5 to 10 ml / liter of butyric acid, soaked for 12 to 24 hours, directly into the seedbed. Alternatively, the naphthalene acetic acid and the talc powder may be uniformly mixed by 1 gram to 1000 grams, and the lower part of the insert may be soaked with fresh water, and then a little powder may be placed on the seed bed. The spray method is formulated as required to spray the plants in corresponding concentration, and the droplets are required to be fine and uniform, and the wetness of the sprayed parts is taken as the degree. In order to make the agent easy to adhere to the surface of the plant, a little emulsifier such as washing powder or surfactant and other auxiliary agents may be added to the agent to increase the adhesion of the agent. Spray as much as possible on the upper middle leaves of the plants. Watering method The plant growth regulator is formulated as an aqueous solution, which is directly irrigated in the soil or mixed with fertilizers, so that the root can be fully absorbed. For potted flowers, the amount of solution required depends on the size of the plants and pots, typically between 200 and 300 ml for a 9 to 12 cm diameter basin. In order to promote plant flowering and control plant stem and branch elongation and growth, 0.1% to 0.3% succinamic acid and CMC solution can be used for irrigation. When smearing with lanolin, the lanolin containing the drug is applied directly to the treated area. Most of the lanolin is applied to the wound, which is conducive to rooting and budding. High-altitude bead cutting and painting method can be used for breeding of rare and difficult rooting flowers. The method is to cut the twigs on the shoots to expose the phloem, smear lanolin containing the auxin in the incision, keep it moist with moss, and wrap it with a film to prevent the water from evaporating.
