The yellowing of plant leaves and slow growth are common phenomena in production, especially for fruit trees. There are many reasons for the yellowing of leaves, some of which are pathological and some are physiological, but they all indicate that the photosynthesis of the leaves is reduced. This affects the synthesis of chlorophyll. Today, I would like to recommend an excellent agent to everyone. After spraying, it can quickly increase the levels of various hormones in the plant body, promote the absorption of nitrogen, phosphorus, potassium and trace elements in the plant, and improve the photosynthesis capacity of the leaves. The leaves will turn from yellow to green in 3 days, and the plants can recover their healthy growth in 7 days.
1. Introduction to the agent
This drug is sodium nitrophenolate, which is a powerful cell activator. After application, it can quickly penetrate into the plant body, promote the flow of cell protoplasm, and improve cell vitality. It can significantly promote the photosynthesis capacity of plants, accelerate the rooting speed of plants, and have different promoting effects on reproduction and fruiting. It is widely used in food crops such as wheat, corn, and rice, cash crops such as peanuts, soybeans, and potatoes, vegetable crops such as cucumbers, tomatoes, eggplants, peppers, and watermelons, fruit trees such as apples, pears, bananas, kiwis, mangoes, longans, litchis, grapes, and guavas, and various Chinese medicinal materials and flowers.
Due to the advantages of high efficiency, low toxicity, no residue, wide application range, no side effects, and wide concentration range, sodium nitrophenolate has been designated by the Food and Agriculture Organization of the United Nations as a plant growth regulator recommended for green food production.
2. Main features
Sodium nitrophenolate is an exogenous regulator that can promote plant growth. It has the following main features:
(1) Extremely high activity: Sodium nitrophenolate has high activity and is used in very small amounts. In production, the content is only 1.8%, and it needs to be diluted 2000 to 4000 times to achieve good results.
(2) Wide range of applications: Sodium nitrophenolate can be widely used in almost all crops such as wheat, rice, corn, cotton, peanuts, soybeans, cucumbers, watermelons, tomatoes, eggplants, peppers, cabbages, kale, cauliflowers, apples, pears, mangoes, litchis, longans, grapes, kiwis, etc.
(3) High safety: Sodium nitrophenolate mainly promotes the protoplasm flow of cells in plants and improves cell vitality. It has no toxic side effects on crops and can be used at any time, such as the seedling stage, flowering stage, and fruiting stage.
(4) Very low cost: Sodium nitrophenolate has extremely high activity and a very low dosage per mu, with a cost of only a few cents. It is currently the lowest-cost plant growth regulator. Therefore, it is the most affordable regulator and can be used on all crops.
(5) Non-toxic and residue-free: Sodium nitrophenolate mainly enhances the physiological activity of animals, stimulates cell metabolism, improves plant immunity, and accelerates cell division and proliferation. It has the advantages of small usage, good effect, and low cost, and has no toxic side effects on humans, animals, and the environment.
3. Usage technology
(1) Use in the seedling stage: Use in the seedling stage of crops such as wheat, corn, rice, and peanuts. Spray with 4000 times of 1.8% sodium nitrophenolate solution + 200-300 times of N+P205+K20≥200g/L humic acid foliar fertilizer. It can promote root growth, make the seedlings stronger, and make the seedlings uniform, strong, and cold-resistant.
(2) Use in the flowering and fruiting period: Use in the fruiting period of vegetables such as tomatoes, cucumbers, eggplants, and peppers. Use 1500-2000 times of 3% sodium nitrate·aminoethyl ester solution per mu. Spray evenly on the whole plant, which can significantly increase the fruit setting rate and promote fruit enlargement.
(3) Restoration of growth: When apple, citrus, pear, strawberry and other fruit trees grow slowly and yellow leaves appear, use 2000-4000 times of 1.8% sodium nitrophenolate solution + 200-300 times of N+P205+K20≥200g/L humic acid foliar fertilizer, spray evenly on the leaves of the whole plant, and the leaves will turn green and resume growth in about 3 days.
(4) Elimination of pesticide damage: For crops such as wheat, corn, watermelon, soybean, and peanut, after pesticide damage occurs, 4000 times of 1.8% sodium nitrophenolate solution can be used, sprayed once every 7 days, and sprayed twice in a row, to quickly eliminate the pesticide damage.
