What are the effects of sodium naphthaleneacetate? How is sodium naphthaleneacetate used? Experienced netizens are also asked to help explainSodium naphthaleneacetate is a colorless crystalline powder with excellent plant growth regulating effects, so Zhongdi Web has compiled the action principles, advantages and usage methods of sodium naphthaleneacetate. The following is a detailed list for netizens' reference.
The effects of sodium naphthaleneacetate:
Sodium naphthaleneacetate is an auxin plant regulator. It enters the plant body through leaves, young epidermis and seeds, and is transported with the nutrient flow to actively growing parts (growth points, young organs, flowers or fruits). Sodium naphthaleneacetate significantly promotes the development of root tips (rooting powder). It induces flowering, prevents flower and fruit drop, forms seedless fruits, promotes early ripening, and increases yield. At the same time, sodium naphthaleneacetate can also enhance the plant's ability to resist drought, cold, disease, salinity and alkaline conditions, and dry hot winds.
Sodium naphthaleneacetate can rapidly promote cell division and expansion (fruit swelling agent, swelling hormone), induce the formation of adventitious roots (rooting agent), and has effects such as regulating growth, promoting rooting, sprouting, flowering, preventing flower and fruit drop, forming seedless fruits, promoting early ripening, and increasing yield. At the same time, sodium naphthaleneacetate can also enhance the plant's ability to resist drought, cold, disease, salinity and alkaline conditions, and dry hot winds. Sodium naphthaleneacetate is a broad-spectrum, high-efficiency, low-toxicity plant growth regulator.
The advantages of sodium naphthaleneacetate:
Advantage one,Sodium naphthaleneacetate has a high content, is used at low concentration, is easy to control in dosage, and has no side effects. Premium sodium naphthaleneacetate is fundamentally different from ordinary sodium naphthaleneacetate. Although the total content of ordinary sodium naphthaleneacetate reaches a certain requirement, its sodium naphthaleneacetate content is still less than 60%, and some are even lower, so its effective activity is very low. Premium sodium naphthaleneacetate is close to a pure product, so an extremely low dosage can achieve an excellent effect.
Advantage two,Sodium naphthaleneacetate exists in solution in a single-molecule form and can enter the plant body through leaves, young epidermis and seeds, and be transported with nutrients to the site of action. It is convenient to use, has both oil and water solubility, and can be made into various formulations.
Advantage three,Sodium naphthaleneacetate has good fast-acting properties and good compatibility. It can be used alone or mixed with sodium nitrophenolate types, fungicides, foliar fertilizers, water-soluble flushing fertilizers, etc.
How to use sodium naphthaleneacetate
1. Preventing flower and pod drop in kidney beans and flower drop in peppers:
During the flowering and pod-setting period of kidney beans, spraying flowers with a 5-25 mg/kg naphthaleneacetic acid solution can effectively reduce flower and pod drop. For peppers, spray the flowers at the flowering stage at a concentration of 50 mg/kg, once every 7-10 days, for a total of 4-5 sprays, which can significantly increase the fruit-setting rate, promote fruit growth, and increase the number of fruits and single fruit weight.
2. Preventing hollow heart in radishes:
At 25-30 days and 35-40 days after sowing radishes, spray once each time with naphthaleneacetic acid at a concentration of 10 mg/kg, which can prevent hollow heart during the growing period; spray once more about 10 days before harvest to control hollow heart during radish storage.
3. Used for cutting propagation of vegetables:
From cucumber plants cultivated in the open field, cut side vines, each segment with 2-3 nodes, quickly dip them in a 500-fold diluted naphthaleneacetic acid solution, and after 11 days of cutting they will root, with a survival rate of up to 85%. For solanaceous vegetables, side branches or main branches can also be used, about 2-3 nodes, and the base can be quickly dipped in a 500-1000-fold diluted naphthaleneacetic acid aqueous solution, and they can root after 10-15 days.
4. Use in tomato cultivation:
(1) Soaking tomato seeds before sowing: Before raising seedlings, soak the seeds in a 5-10 mg/kg naphthaleneacetic acid solution for 10-12 hours, then rinse clean with water and sow. After the seeds soaked for germination emerge, the seedlings are neat, robust, and more cold-resistant, and the occurrence of tomato late blight can also be prevented.
(2) Use in tomato seedbeds: After tomatoes emerge, if the seedlings grow thin and weak and the leaves turn yellow, spray the whole plant once with a 5-7 mg/kg naphthaleneacetic acid solution, and the seedlings can return to normal growth. In the middle and later stages of seedling growth, when the temperature in the seedbed is 26°C-28°C, spray once with a 5-7 mg/kg naphthaleneacetic acid solution, which can prevent the occurrence of tomato early blight.
(3) Use before and after tomato transplanting: 6-7 days before tomato transplanting, spray once with a 5 mg/kg naphthaleneacetic acid solution, which can not only promote growth and strengthen the plant, but also promote early budding. After transplanting, spray once every 10-15 days with a 5 mg/kg naphthaleneacetic acid solution, for a total of 2 sprays, which can prevent the occurrence of tomato early blight and viral disease.
(4) Use during the full fruit-bearing period of tomatoes: When young tomato fruits grow to the size of an egg, spray the whole plant once with a 10 mg/kg naphthaleneacetic acid solution, and spray twice in succession, which can promote fruit expansion, thicken the fruit flesh, and increase sugar content.
(5) Use in the later stage of tomatoes: For indeterminate-growth tomatoes, in the later fruit-bearing stage, spray the whole plant once with a 10 mg/kg naphthaleneacetic acid solution, which can prevent premature plant senescence, extend the harvest period, and increase total yield.
Precautions for using sodium naphthaleneacetate:
Note one: Sodium naphthaleneacetate cannot be directly mixed or compounded with acidic pesticides or fertilizers.
Note two: Sodium naphthaleneacetate needs to be used at a reduced dosage during the crop seedling stage.
Note three: The use concentration of sodium naphthaleneacetate must not be increased at will, otherwise it will inhibit crop growth.
