Gibberellin is a high potency broad-spectrum plant growth regulator. It can promote the elongation of cells and stems, increase the height of plants, promote the growth of genetic dwarfing plants, promote the growth of physiological or viral dwarfing plants, break the dormancy of seeds, tubers and bulbs of certain vegetables, and increase the germination rate. , From the vernalization of vernalization and long days, to promote and induce long-day vegetable bloom in the year; To promote the growth and development of fruits, fruits and fruits, and the effects of gibberellin under low temperature, drought, low light or short days of sunshine and other adverse conditions More significant. A. Formulations and mother liquor formulations are 85% crystalline powder, 4% EC, and 10 mg tablets. Emulsifiable concentrates and tablets are readily soluble in water and can be formulated and used directly. Difficult to dissolve in water, soluble in alcohol, so when preparing, take 1g Crystal powder, into the measuring cylinder, add a small amount of alcohol or high concentration of liquor dissolved, diluted with water to 1000mL, ie about 1000mg/kg of gibberellin mother liquor, can not be heated when dispensing, the water temperature shall not exceed 50 °C, according to the required concentration Take the mother liquor. Second, the application of technology in vegetables 1. Anti-aging and preservation Before cucumbers are harvested, 25-35mg/kg can be used to prolong the storage period. Before harvesting, 25～35mg/kg melon can extend the storage period. Garlic alfalfa 40 ~ 50mg/kg 10 ~ 30min base treatment garlic garlic, can inhibit the upward transport of organic matter, preservation. 2. Flower protection, promote fruit growth tomato, 25 ~ 35mg/kg, flowering spray 1, can promote fruit set, anti-air hole fruit. Eggplant, 25 ~ 35mg/kg, flowering spray 1 time, promote fruit setting, increase production. Pepper, 20 ~ 40mg/kg, spray 1 flowering time, promote fruit setting, increase production. Watermelon, 20mg/kg, spray flowering 1 times to promote fruit set, increase production. Or young larvae spray larvae 1 time, promote the growth of young larvae, increase production. 3. Promote vegetative growth, mentioning celery in the morning, 15 to 30 days before harvesting, 35 to 50 mg/kg, and spraying once every 3 to 4 days for a total of 2 times, increasing production by more than 25%, stem and leaf hypertrophy, and 5 to 6 days in the morning. Leek, sprayed at 20mg/kg 3cm after plant height 10cm or 3 days after harvest, increased 15%. Mushrooms, 400mg/kg, when the primordium was formed, the dip blocks appeared, the fruit body increased, and the yield increased. 4. Inducing male flowers and increasing seed production When cucumbers are used for seed production, spraying 50 to 100 mg/kg gibberellin on 2 to 6 true leaves of the seedlings can reduce female flowers and increase male flowers, so that female plants become male and female. 5. Promote bolting and flowering, improve breeding coefficient of improved varieties. With 50-500 mg/kg gibberellin sprayed on the plant or dripping growth point, carrots, kale, radish, celery, Chinese cabbage and other two-year growing sunshine crops can be convulsed under short-day conditions before wintering. 6. Breaking the dormancy with 200 mg/kg gibberellin germinates at a high temperature of 30-40°C for 24 hours after germination, which can successfully break the dormancy of lettuce seeds. This method is more convenient than the folk deep well hanging method, and the germination is stable. To break the dormancy of potato tubers, a 0.5 to 2 mg/kg gibberellic acid solution was immersed in potato chips for 10 to 15 minutes, or soaked in 5 to 15 mg/kg of whole potatoes for 30 minutes, and the dormancy period of the short-cultivated varieties was lower and longer. To break the dormancy of strawberry plants, in the strawberry greenhouses to promote cultivation, semi-conductivity cultivation, 3 days after the cover shed insulation, that is, when the buds appear more than 30%, each spray 5 ~ 10mg/kg gibberellic acid solution 5mL, focus on spraying the heart leaf, Can make flowering ahead of flowering, promote growth and mature earlier. 7. Is an antagonist of paclobutrazol, chlormequat and other inhibitors Too much damage due to the use of excessive antioxidants can be used 20mg/kg GA. Third, pay attention to matters 1. Can not be mixed with alkaline substances, but can be mixed with acidic, neutral fertilizers, pesticides, mixed with urea to produce better results. The aqueous solution is easily decomposed and should not be released for a long time. 2. The use of gibberellin can only exert good results under the condition of sufficient supply of fertilizer and water, and it cannot replace fertilizer. 3. Must use the appropriate concentration and the use of the time, the concentration is too high, there will be leggy, white, until the deformity or withered, the concentration is too low, the effect is not obvious. The amount of liquid used for leafy vegetables differs depending on the size and density of the crop plants. Generally, the amount of liquid used per 667m2 is not less than 50kg.
