Looking at the New Industry Opportunities Behind Lawn Growth Regulator

Plant growth regulators can affect multiple stages of plant growth and development. In actual production, plant growth regulators play specific roles including induction of callus, rapid propagation and detoxification, promotion of seed germination, regulation of seed dormancy, promotion of rooting, Regulate growth, regulate plant type, regulate flower bud differentiation, regulate floral nature, induce seedless fruit, preserve flowers and fruit, thin flowers and fruit, regulate fruit maturity, prevent fruit cracking, strengthen seedlings and seedlings, prevent lodging, improve stress resistance, and improve Crop quality, increase yield, storage and preservation, etc.The application effect of plant growth regulators is related to the specific application technology. For example, the use of auxin regulators at low concentrations can promote crop growth, while high concentrations can inhibit plant growth.Plant growth regulators have a wide range of applications, which can be divided into the following 6 areas:It is applied to field crops, such as rice, wheat, corn, rape, peanut, soybean, sweet potato, cotton and potato.Applied to vegetables, such as melons, beans, cabbage, cabbage, fungi, solanaceous fruits, onions and garlic, root vegetables, green leafy vegetables, etc.Applied to fruit trees, such as apples, cherries, grapes, bananas, citrus, ginkgo, peach, pear, etc.Used in forestry, such as fir, pine, eucalyptus, camellia, poplar, rubber tree, etc.Applied to special plants, such as aromatic plants, medicinal plants, sweet sorghum, sugar beet, sugar cane, tobacco, tea trees, etc.Applied to ornamental plants, such as herbal flowers, succulents, woody plants, etc.

Plant growth regulators are the product of comprehensive development of various scientific technologies such as organic synthesis, microanalysis, plant physiology and biochemistry, and modern agriculture, forestry and horticulture. In the 1920s and 1930s, traces of natural plant hormones such as ethylene, 3-indole acetic acid and gibberellin were found in plants, which have the effect of controlling growth and development. In the 1940s, research on synthetic analogues began, and 2,4-D, amine fresh ester (DA-6), chlorpyrifos, sodium nitrophenolate, α-naphthylacetic acid, and bud-dan were gradually developed. Promote use and form a category of pesticides (see table). More than 30 years of artificial plant growth regulators have been synthesized, but due to the complicated application technology, their development is not as rapid as pesticides, fungicides and herbicides, and the application scale is also small. However, from the perspective of the needs of agricultural modernization, plant growth regulators have great potential for development, and there has been a trend of accelerated development in the 1980s. China has been producing and applying plant growth regulators since the 1950s.For the target plant, the plant growth regulator is an exogenous non-nutritive chemical that is usually transported to the site of action in the plant and promotes or inhibits certain aspects of its life process at very low concentrations. To meet the needs of human development. Each plant growth regulator has a specific use, and the application technology requirements are quite strict, and specific effects can be exerted on the target plant only under specific application conditions (including external factors). Frequent changes in concentration result in opposite results, such as a promotion at low concentrations and inhibition at high concentrations. Plant growth regulators have many uses, depending on the variety and target plant. For example: control germination and dormancy; promote rooting; promote cell elongation and division; control lateral buds or tillers; control plant type (short-strong anti-fall); control flowering or sex ratio, induce no fruit; flower thinning, control fruit drop Control the shape or maturity of the fruit; enhance stress resistance (resistance, drought resistance, salt tolerance, antifreeze); enhance the ability to absorb fertilizer; increase sugar or change acidity; improve flavor and color; promote latex or resin secretion; Or evasive (for easy mechanical harvesting); preservation and so on. Some plant growth regulators are herbicides used at high concentrations, and some herbicides have growth regulation at low concentrations.

1 Wide range of applications, many applications. Plant growth regulators can be applied to almost all high and low plants in the crop industry, such as field crops, vegetables, fruit trees, flowers, trees, kelp, seaweed, edible fungi, etc., and regulate the photosynthesis, respiration, Material absorption and operation, signal transduction, stomatal opening and closing, osmotic adjustment, transpiration and other physiological processes regulate the growth and development of plants, improve the interaction between plants and the environment, enhance the resilience of crops, and increase crop yields. Improve the quality of agricultural products, so that the expression of crop agronomic traits develops in the direction of people's needs.2 Small dosage, fast speed, high efficiency, less residual toxicity, most crops only need to be sprayed once every one season.3 Can regulate the external traits of plants and internal physiological processes.4 Targeted and professional. It can solve problems that are difficult to solve by other means, such as forming seedless fruits, controlling windy winds, controlling plant type, promoting rooting of cuttings, ripening and coloring of fruits, inhibiting growth of axillary buds, and promoting cotton leaf detachment.5 The use effect of plant growth regulators is affected by many factors, and it is difficult to achieve the best. The climatic conditions, the time of application, the amount of drug used, the method of application, the site of application, and the absorption, operation, integration and metabolism of the crop itself will affect its effects.
