What is gibberellin? How to use gibberellin? Do netizens who know about gibberellin help introduce that gibberellin is a broad-spectrum plant growth regulator, which can promote crop cell elongation, leaf enlargement, parthenocarpy (seedless), and fruit growth. Gibberellin can break seed dormancy and change the ratio of female and male flowers of crops, which can affect the flowering time of crops and reduce the shedding of crop flowers and fruits. Therefore, the farming network collates the use of gibberellin in common crops and crops, which are listed in detail below for netizens' reference. The effect of gibberellin on rice: because there are serious problems in hybrid rice seed production, which is not conducive to cross-pollination of rice, thus reducing seed setting rate and affecting seed production, but the use of gibberellin can effectively solve these problems. The method of using gibberellin in rice: 15 grams of gibberellin 10 per mu of rice was sprayed twice. When the first spraying time was 10% of rice heading, 3 grams of gibberellin per mu was sprayed with water; the second time was sprayed the next day with 6 grams of gibberellin per mu with 6 grams of water; and the third time was sprayed the next day with gibberellin 4 grams per mu with 6 grams of water. Spraying gibberellin on fruit trees can improve the fruit setting rate of fruit trees. The method of applying gibberellin to citrus trees: spraying the whole fruit tree with 50 grams of gibberellin and 1000 kilograms of water after blooming; spraying the same concentration of gibberellin again every 20 days can reduce the physiological fruit drop of citrus trees. When spraying, we should pay attention to the concentration should not be too high, otherwise it will affect the citrus color and fruit. The method of applying gibberellin to jujube trees: in the early flowering stage of jujube trees, spray 15 grams of gibberellin with 1000 kg of water and spray on the crown of jujube trees. Spraying gibberellin on vegetable crops can promote crop vegetative growth, increase yield and go on the market ahead of time. The method of using gibberellin in celery: 15 and 30 days before celery harvest, 20 grams of gibberellin and 1000 kilograms of water were sprayed twice. The method of using gibberellin for lettuce: when the lettuce grows to 14 leaves, spray gibberellin 10ml 20g with water 1000 kg. The method of using gibberellin for leek: 2 to 3 days after the leek harvest, spray with gibberellin 10ml 20g in water 1000 kg. Gibberellin can break the dormancy of potato, the method is as follows: soak the potato seed potato pieces in a solution of 1000 kg of water and 0.5ml of gibberellin for 15 minutes, for example, if the dormancy period of potato variety is short, the gibberellin concentration is lower; after soaking, the seed potato is removed and placed in a cool place to dry, do not expose in the sun, and then sow. Soaking with gibberellin can promote the germination of seed potato and make its emergence early and neatly. The method of using gibberellin in strawberries: spraying 10 grams of gibberellin with 1000 kilograms of water in the early bud of strawberries can prevent strawberries from dormancy and promote strawberries to blossom and bear fruit. Precautions for the use of gibberellin: 1. Because gibberellin powder is insoluble in water, it needs to be dissolved with a small amount of ethanol or wine before use. 2. Gibberellin can be mixed with acidic pesticides, but not with alkaline pesticides. 3. The preparation (dissolution) of gibberellin solution should not be kept for too long, so as not to affect the efficacy. 4, gibberellin can not be heated, once the temperature exceeds 60 degrees, it will lose its effect. 5. The physiological activity of gibberellin is very strong, and the concentration is generally low, so we must strictly grasp the concentration and the amount of liquid when using it. 6. short-term "chlorosis" will occur after the use of gibberellin, so the management of fertilizer and water should be strengthened after the use of gibberellin.
