The plant growth regulator is not a panacea, but it plays a certain role in stimuli. That is to say, it is necessary to strengthen the comprehensive cultivation techniques and, according to the purpose of use, play its role.
Reasonable selection: According to the purpose of use, choose an effective plant growth regulator. If the growth of shoot shoots is inhibited and the flower bud differentiation is promoted, a certain concentration of B9 can be used; to ripen the fruit, a certain concentration of ethephon can be used, and a certain concentration of defoliation can be selected to control the length of the cotton. In use, it is also necessary to consider the effects of factors such as variety, plant growth status, climatic conditions and methods of use. Therefore, it should be subjected to small-scale tests before it can be widely used.
Master concentration: Since the concentration of the coherent growth regulator is low, and many agents have a dual effect (promoting growth or inhibiting growth), it is difficult to master the drug technology, and the required drug concentration must be accurately prepared according to different time and crops. , reasonable use. According to the local experiments, when the plant growth retardant is used to inhibit the growth, the small dose is applied once, so that the inhibition can be maintained frequently, the toxicity to the plant and its objective side effects can be avoided, and the absorption of the drug by the plant can be increased. .
Period of use: The appropriate period of time is determined by the type of plant growth regulator, the duration of the effect, and the purpose of use. For example, citrus aurantin in the bud differentiation stage of citrus flower will inhibit the formation of flower buds; however, the rate of citrus fruit.
Mixed with each other: Several plant growth regulators are used in combination, and the effect is more ideal as a new trend in the development of plant growth regulators in the future. However, it is necessary to understand whether there is synergy between the mixed plant growth regulators. If B9 is mixed with Bili, it can promote flower bud differentiation. Mixing with medicine Some plant growth regulators cannot be mixed with certain pesticides. For example, B9 cannot be used in combination with copper pesticides; ethylene and puromycin cannot be mixed with alkaline pesticides. When used separately, at least 5 days or more; the concentration of naphthaleneacetic acid.
