What are the effects of sodium naphthalene acetate?

What are the effects of sodium naphthalene acetate? How to use sodium naphthalene acetate? Experienced netizens are also invited to help introduce sodium naphthalene acetate, a colorless crystalline powder with excellent plant growth regulation effect, so the farming network has sorted out the action principle, advantages and usage of sodium naphthalene acetate. The following is listed in detail for netizens' reference. The role of sodium naphthalene acetate: sodium naphthalene acetate is a plant regulator of auxin, which enters the plant through leaves, tender epidermis and seeds, and is transported to the vigorous growth parts (growth point, young organs, flowers or fruits) with the nutrient flow. Sodium naphthalene acetate obviously promotes the tip development of root system (rooting powder). It can induce flowering, prevent falling flowers and fruits, form seedless fruits, promote early ripening and increase production. At the same time, sodium naphthalene acetate can also enhance the ability of plants to resist drought, cold, disease, salt and alkali, dry and hot wind. Sodium naphthalene acetate can rapidly promote cell division and expansion (fruit expanding agent, dilatonin) and induce adventitious roots (rooting agent). It can regulate growth, promote rooting, sprout, blossom, prevent falling flowers and fruits, form seedless fruits, promote prematurity and increase production. At the same time, sodium naphthalene acetate can also enhance the ability of plants to resist drought, cold, disease, salt and alkali, dry and hot wind. Sodium naphthalene acetate is a broad-spectrum, high-efficiency and low-toxic plant growth conditioner. The advantages of sodium naphthalene acetate: excellent point 1, high content of sodium naphthalene acetate, low concentration, easy to control dose, no side effects. There is an essential difference between fine sodium naphthalene acetate and sodium naphthalene acetate. Although the total content of sodium naphthalene acetate meets certain requirements, the content of sodium naphthalene acetate is less than 60%, and some are even lower, so its effective activity is very low. The fine sodium naphthalene acetate is close to the pure product, so an excellent effect can be achieved with a very low dose. Second, sodium naphthalene acetate exists as a single molecule in the solution, which can enter the plant through leaves, tender epidermis and seeds, and flow to the active site with nutrition. Easy to use, with oil and water solubility, can be made into a variety of dosage forms. Excellent point 3, sodium naphthalene acetate has good quick effect and good compatibility, which can be used alone or mixed with compound sodium nitrate, fungicides, leaf fertilizer, flushing fertilization and so on. The use of sodium naphthalene acetate 1. Prevention and control of bean pod shedding, pepper falling: bean blossom and pod stage, spraying with 525 mg / kg naphthalene acetic acid solution can effectively reduce flower drop and pod drop. Spraying pepper at flowering stage with the concentration of 50 mg / kg, spraying once every 7 days and 10 days for a total of 4 times could significantly increase the fruit setting rate, promote fruit growth, and increase the number of fruit and the weight of single fruit. 2. Control the heart of radish bran: spraying 10 mg / kg naphthylacetic acid once at 25 and 35 days after radish sowing can prevent the heart of radish bran during the growing period, and spraying it again about 10 days before harvest can control the heart of radish during storage. 3. Used for cutting propagation of vegetables: lateral vines were cut from cucumber plants cultivated in the open field, and each segment was 2-3 nodes, then quickly dipped in 500 times diluted naphthalene acetic acid solution, rooting after cutting for 11 days, and the survival rate reached 85%. Eggplant fruit vegetables can be used side branches or main branches can also be about 2-3 nodes, quickly dipped in 500-1000 times diluted naphthalene acetic acid aqueous solution at the base, and can take root after 10-15 days. 4. Use in tomato planting: soak the seeds of ⑴ tomato before sowing: soak the seeds with 5 mg / kg naphthalene acetic acid for 10 hours before raising seedlings, then rinse the seeds with clean water. After the emergence of the seeds, the seedlings are neat, robust, cold-resistant and can prevent the occurrence of tomato blight. ⑵, the use of tomato seedling bed: after tomato emergence, if the growth of tomato seedlings is weak and the leaves turn yellow, the seedlings can return to normal growth by spraying the whole plant with 5-7 mg / kg naphthylacetic acid once. When the seedling enters the middle and later stage, when the temperature in the seedling bed is 26 ℃ ~ 28 ℃, spraying 5-7 mg / kg naphthylacetic acid once can prevent the occurrence of tomato early blight. The use of ⑶ and tomato before and after planting: spraying 5 mg / kg naphthylacetic acid once 6-7 days before planting can not only promote the growth and sturdiness of plants, but also promote the early budding of plants. Spraying 5 mg / kg naphthalene acetic acid once every 10-15 days after planting can prevent the occurrence of tomato early blight and virus disease. ⑷, used in the full fruit period of tomato: when the young fruit of tomato grows to the size of egg, the whole plant is sprayed with 10 mg / kg naphthylacetic acid solution for 2 times, which can promote the fruit expansion, thicken the pulp and increase the sugar content. ⑸, used in the later stage of tomato: infinite growth type tomato, spraying the whole plant with 10 mg / kg naphthylacetic acid once can prevent premature senescence, prolong the harvest time and increase the total yield. Points for attention in the use of sodium naphthalene acetate: first, sodium naphthalene acetate can not be directly mixed with acid pesticides and fertilizers. Note that sodium naphthalene acetate needs to be reduced in the crop seedling stage. Note that the concentration of sodium naphthalene acetate should not be increased at will, otherwise it will inhibit the growth of crops. What are the functions of plant auxin? what are the dilatins?
