| Product characteristics | The main function of sodium naphthalene acetate is to promote the development of plant main roots, which is widely used in Flushing fertilization and foliar fertilizer. Sodium naphthalene acetate in promoting the formation of adventitious roots and roots of the use of technology: 1, the use of sodium naphthalene acetate on grapes: 100-200ppm sodium naphthalene acetate solution dip branches, can promote the rooting of branches, germination, plant development; 2, fruit transplanting: 100-200ppm sodium naphthalene acetate solution dipped in the root after transplanting, can promote rooting, improve the survival rate; 3, Mulberry, tea, metasequoia glyptostroboides with sodium naphthalene acetate: 10-15ppm of sodium naphthalene acetate at the base of cutting branches for 24 hours, can promote rooting. sodium a-naphthalene acetate is a broad-spectrum plant growth regulator, it has the role of endogenous auxin characteristics and physiological functions, can promote adventitious roots and root forms, accelerate the rooting of cuttings and seed root, it can promote the division and expansion of cells, promote the differentiation of buds and flower buds, accelerate the synthesis of chlorophyll, promote the expansion of fruits to prevent the fall of flowers and fruits, change the ratio of male and female flowers, and promote the growth of plant roots and leaves, increase yield, improve quality, Enhanced resistance to drought, cold, disease resistance and other resilience. high purity sodium α-naphthalene acetate belongs to auxin plant growth regulator, which has three main functions. (a) naphthalene sodium acetate can promote the formation of adventitious roots and root formation, so can be used to promote the seed root, root, but the concentration is too large to inhibit rooting. (two) sodium naphthalene acetate can promote the expansion of fruit and tuber tuber expansion, so it can be used as a filling agent. Field experiments have proved that the fruit, grape, watermelon, cucumber, tomato, pepper, eggplant, pear, apple, can greatly increase the yield, improve the quality. At the same time to promote the rapid expansion of the cells, the treated eggplant, the growth rate of a miracle change. The effect of mushrooms is particularly significant, and does not reduce the quality of the fruit. (3) sodium naphthalene acetate has the function of preventing falling flowers and fruits from falling. In addition, sodium naphthalene acetate also has general auxin functions, such as promoting growth, promoting chlorophyll synthesis, and promoting differentiation of buds and flower buds. Therefore, sodium naphthalene acetate has the effect of promoting flowering and fruit set, promoting the growth of branches and leaves, increasing yield and improving quality, and improving the resistance to drought, cold and lodging of crops. |
| high-purity sodium α-naphthalene acetate | high-purity sodium α-naphthalene acetate is over 98% pure, contains a small amount of water and does not contain other organic impurities, therefore, in its effective use concentration range will not produce any harm to crops, and ordinary alpha-naphthalene sodium acetate because it contains 20% of organic impurities, in the effective use of the concentration range of the young leaves of plants, buds, seedlings can cause harm. Light causes black spots, heavy causes death, and some organic impurities cause harm to the human body and the environment. For any plant growth regulator and pesticide, its purity is related to its effect, such as high purity alpha-naphthalene sodium acetate 5ppm(5 μg/g) has a good effect, ordinary sodium alpha-naphthalene acetate needs to reach 20ppm(20g/g) to be effective. high purity α-naphthalene sodium acetate has water and oil two soluble, so it can be separately made into dosage forms such as water agent, powder, emulsifiable concentrate, granule, etc. It is very convenient to use and the effect is very good. Because it is a single molecule in the solution, dispersed evenly, easy to be absorbed by plants, and the ordinary content of 80% can only be dissolved in oil, the use of very inconvenient. It needs to be diluted with ethanol and the like, and it exists in the state of a molecular group in the emulsifiable concentrate powder, and the dispersibility is poor, and the effect is naturally not good. high purity sodium α-naphthalene acetate can be used in combination with many plant growth regulators, such as auxin, compound sodium nitrophenolate, bactericide, fertilizer, etc. However, ordinary sodium α-naphthalene acetate has not yet been used in combination. |
