The world's new plant growth material, DA-6, is a substitute for plant growth regulators such as gibberellins, nitro compounds, naphthalenes, and adenines. It has been called a plant growth regulator by botanists and agricultural scientists worldwide. Revolution. DA-6 was first discovered by American scientists in the early 1990s. It is the most highly respected compound in the international academic community and has high biological activity. It has been proved by domestic and foreign experiments that DA-6 is a newly discovered and highly effective plant growth material, and it has significant yield-increasing, stress-resistance, disease-resistance, quality-improving and premature-maturing effects on various crops. DA-6 is non-toxic, has no side effects, no residue, and has good compatibility with the ecological environment. This is not available for other plant growth promoters. It can be compounded with various elements and can also be used with fungicides. Enhance the plant's disease resistance and increase the bactericidal effect; this feature is also unmatched by other plant growth regulators. Because of its many advantages mentioned above, it has attracted more and more attention from people. DA-6 has become the most popular new type of plant growth promoter recently researched and developed to obtain broad application and promotion. It can enhance crop cold resistance and drought resistance. Anti-mite, anti-mite, lodging resistance, disease resistance, anti-drug resistance and other stress resistance, can increase production by 25-60%, early maturity 5-20 days, can improve the product of protein, amino acids, vitamins, sugar, carotene and other nutrients The content. Improve the quality of the products, make the fruit products color well, the appearance of the fruit is beautiful, the taste is good, the commodity is improved, and the growth period of the vegetables is extended. First, the functional characteristics of DA-6 (1) broad-spectrum: can be used for a variety of economic crops and food crops and crop growth and development of the entire life cycle. (2) Non-toxic, non-pollution, no residue. DA-6 is a carboxylester that has no toxic effects on humans and animals and does not remain in nature. (3) High efficiency: With less dosage, the efficacy and fertilizer efficiency can be significantly improved, and the use of pesticides and fertilizers can be reduced. (4) It can improve the quality of crops and increase production. Has special detoxification effects. (5) To promote photosynthesis, DA-6 can increase the chlorophyll content. After three days of application, the leaves grow thick green, transform, increase the photosynthetic rate, increase the absorption of CO2 by plants, adjust the C/N ratio of plants, strengthen the leaves and The resistance of the plants to the overall growth of the plants is significantly better than other plant growth regulators. (6) Regulation can be performed at low temperatures, and other plant growth regulators do not have significant regulation at low temperatures, thus limiting their use in plastic greenhouses and winter crops. DA-6 at low temperatures, as long as the plant has a growth phenomenon, DA-6 has both regulatory effects, so it can be widely used in plastic greenhouses and winter crops. (7) Strong stability, aromatic ring compounds are flammable, DA-6 powder is non-flammable, non-explosive, according to the general chemical storage and transportation, there is no hidden trouble in storage and use. (8) With remission, plant growth regulators such as aromatic ring compounds, adenine, and auxin have a fast effect, but the effect quickly disappears. DA-6 has a slow-release effect. It is quickly absorbed and stored by plants. Some of them work quickly and the other slowly. Therefore, after application of DA-6, it will be effective in three days, and the plant growth can be seen in 7-10 days. The effective period can last 20-30 days. (9) DA-6 itself is not a plant hormone, but after plant absorption, it can regulate the activity and reasonable balance of auxin, cytokinin, gibberellin, abscisic acid, ethylene, etc. In the desired direction, generally using DA-6 in the early stages, plants will speed up vegetative growth, and DA-6 in the middle and later stages will increase flowering, fruit set and fruit ripening. This is a property that aromatic ring compounds and other plant growth regulators do not have. (10) The use of a wide range of concentrations, DA-6 has a wide range of use concentration, that is, from 1-100PPm (μg/g) have a good regulatory effect on plants, different concentrations of its role with different time peaks and The effect of increasing production was not found to have side effects and phytotoxicity. Second, DA-6 application technology (a) DA-6 original powder alone can be made directly into liquid and powder, the concentration can be formulated according to need, easy to operate, does not require special processes and equipment. When DA-6 is used alone, the best effect is 10-15PPm (μg/g). (B) Compound application (combined with fertilizers, fungicides, insecticides and herbicides, with the best effect of 10PPm (μg/g)) 1. With compound fertilizer application, DA-6 can be used directly The use of complex elements, with good compatibility. It does not require additives such as organic solvents and additives and is very stable and can be stored for long periods of time. And can increase the plant's ability to assimilate, accelerate plant absorption and utilization of fertilizers, increase fertilizer efficiency by more than 30%, and reduce fertilizer use. 2. For compounding with fungicides, DA-6 is a neutral substance that can be compounded with various fungicides. Both have obvious synergistic effects, can increase efficiency by more than 30%, and reduce the dosage by 10-30%. Experiments have shown that DA-6 has inhibitory and preventive effects on various plant diseases caused by fungi, bacteria, viruses, and the like. 3. In combination with insecticides, DA-6 is a neutral substance that can be used with a variety of insecticides. It can increase plant growth and enhance plant resistance to insects, and DA-6 itself has repellent use against molluscs. After compounding with DA-6 and insecticide, the insecticide increases yield and achieves double effect. 4. It can be used as herbicide antidote. It has been proved by experiment that DA-6 has detoxification effect for most herbicides. 5. When used together with herbicides, it can effectively prevent the poisoning of crops without reducing the effect of herbicides and enable the safe use of herbicides. For poisoned crops, DA-6 can be used for detoxification, allowing crops to quickly return to life and reduce economic losses.
Imported Premium Plasticizer
Plasticizer is widely used in industrial production of polymer materials, also known as plasticizer. Any substance added to a polymer material that increases the plasticity of the polymer is called a plasticizer. Plasticizer can improve the performance of polymer materials, reduce production costs and increase production benefits. [1] is a kind of important additives, chemical products as additives commonly used in plastics, concrete, mortar, the material such as cement, gypsum, cosmetic and detergent, especially in PVC plastic products, in order to increase the plasticity of the plastic and improve the strength of the plastic, you need to add phthalic acid ester, sometimes its content can be up to 50% of the products. Weakened the effect of plasticizer mainly resin molecular valence bond between time, increase the mobility of the resin molecular bonds, reducing resin molecular crystalline, increase the plasticity resin molecules, enhanced the flexibility, easy to machining, can legally used for industrial purposes, widely exists in food packaging, cosmetics, medical equipment, water and environment. Such as plastic wrap, food packaging, toys and so on.
