How to use naphthalene acetic acid
How to use naphthalene acetic acid: a comprehensive analysis
NAA (Naphthaleneacetic Acid, NAA) is a chemical substance commonly used in plant growth regulation, which is widely used in agriculture, horticulture and other fields. As a synthetic plant hormone, naphthalene acetic acid can effectively promote the growth and development of plants, especially in the root development, flower and fruit development and stress resistance of plants. How to use naphthalene acetic acid in order to achieve the best results? This article will introduce the use of naphthalene acetic acid, application areas and precautions.
1. NAPHTHAETIC ACID BASIC CHARACTERISTICS
Naphthalene acetic acid is an auxin compound, mainly used to stimulate the growth of plants. It affects the cell division and expansion of plants, thereby promoting the growth of roots, the luxuriant foliage of plants and the formation of fruits. Compared with natural auxin, naphthalene acetic acid has stronger stability and longer lasting effect, so it has been widely used in agricultural production.
2. How to use naphthalene acetic acid to promote plant growth
When using naphthalene acetic acid, the appropriate concentration and application method should be determined according to the needs of different plants. In general, naphthalene acetic acid can be applied by foliar spraying, root dipping, watering, etc.
-
Foliar spray method: Dissolve naphthalene acetic acid in water, usually at a concentration of 10-50 mg/L, and spray it evenly on the leaves of plants with a sprayer. This method is suitable for promoting flowering and fruit formation in plants, especially in fruit trees and vegetables.
-
Dip root method: the naphthalene acetic acid solution soak plant roots to promote root growth and improve plant resistance. The soaking time is usually 30-60 minutes, and the concentration is generally 50-100 mg/L.
-
Irrigation method: adding an appropriate amount of naphthalene acetic acid solution to the soil of the plant can effectively stimulate the root growth of the plant. This method is often used for crops and fruit trees grown in large areas.
3. Naphthalene acetic acid application field
Horticulture: In horticultural cultivation, NAA is often used to promote the development of flowers and fruit trees. It can not only help increase the fruit setting rate of fruits, but also increase the flowering length of flowers and make horticultural crops more beautiful.
Agricultural production: In agriculture, naphthalene acetic acid is used to promote the growth and development of crops, especially for fruit trees. It can effectively improve the fruit setting rate of fruit trees and help to ripen and increase the yield of fruit.
Plant Breeding: NAA can also be used to promote sexual and asexual reproduction in plants. In the breeding process, it can improve the germination rate of seeds and the growth rate of seedlings, and help the breeding work to be more efficient.
4. How to correctly use naphthalene acetic acid to avoid side effects
Although naphthalene acetic acid has many advantages, improper use may also cause some side effects, such as inhibiting the normal growth of plants or causing plant diseases. Therefore, the use of naphthalene acetic acid should follow the following principles:
-
Control concentration: different plants have different sensitivity to naphthalene acetic acid, too high concentration may lead to plant wilting, yellowing and other symptoms. In general, the concentration is controlled within a suitable range and the dosage recommended by the instructions is followed.
-
Use time: Avoid use in extreme weather conditions, such as high temperature or heavy rain. Excessive use of naphthylacetic acid should be avoided during flowering and fruit setting in plants, so as not to affect flowering and fruit development.
-
Frequency of use: The frequency of use of naphthalene acetic acid should also be appropriate. Over-frequent use may lead to uneven growth of plants, so the number of uses should be reasonably arranged according to the needs of plants.
5. How to use naphthalene acetic acid for plant disease control
Naphthylacetic acid can not only promote plant growth, but also enhance the resistance of plants to help plants resist diseases and insect pests. Through the rational use of naphthalene acetic acid, the immunity of plants can be enhanced, which can better adapt to the changes of the external environment and reduce the occurrence of diseases.
How to use naphthalene acetic acid needs to choose the appropriate application method and concentration according to the needs of different crops. In agriculture and horticulture, the rational use of NAA can significantly improve the yield and quality of crops and promote the healthy growth of plants.
Conclusion
NAA, as an efficient plant growth regulator, has been widely used in agricultural production. Understanding how to use naphthalene acetic acid and mastering its application skills is one of the important ways to improve crop yield and quality. In the process of use, reasonable control of the concentration and timing of use can avoid unnecessary side effects and ensure the healthy growth of plants.
