Gibberellin is a widespread plant hormone. The chemical structure is a diterpenoid acid and is derived from a tetracyclic skeleton. There are at least 38 gibberellin species used in agricultural production, which can stimulate the growth of leaves and shoots and increase yield. It is used for potato, tomato, rice, wheat, cotton, soybean, tobacco, fruit trees and other crops to promote its growth, germination, flowering and fruiting; it can stimulate fruit growth and increase seed setting rate, and it can be used for rice, cotton, vegetables, fruits, green fertilizer Has a significant increase in production. , And then dilute the water to the required concentration, spray three times in the flowering period (each time interval of 7 days). An aqueous solution of 10-15 ppm is usually used on fruit trees. (ppm is the percentage of weight, which means "parts per million", such as 1 ppm is part per million. Features; Its effect on crops is 100% effective, lasting, more efficient, more stable, safer. Spraying at the seedling stage can develop root systems and prevent diseases. It can significantly promote the growth of plant stems and leaves, such as Spraying in the period can also make the nutrition balanced and help the growth of the crop. Spraying in the flowering period can protect the flowers and fruits, and can also enlarge the fruit. Bell rate and can effectively relieve crop diseases Gibberellin is suitable for the following crops: cotton, tomato, potato, fruit tree, rice, wheat, soybean, tobacco, etc., to promote its growth, germination, flowering and fruiting; it can stimulate fruit growth, improve seed setting rate, Fruit, rice, green manure, etc. have a significant yield increase effect. Main uses Used as a plant growth regulator for fruit trees, potatoes, tomatoes, rice, wheat, cotton, soybeans, tobacco, etc., to promote its growth, germination, flowering, and fruiting.
