1, 2, 4-D, anti-fallin, naphthaleneacetic acid 2,4-D is marketed as an injection, each concentration of water is 400-500 grams is 15-20 mg / kg. Use this concentration of 2,4-D to coat the flower stalks from 9:00 am to 3:00 pm on the day of tomato flowering to prevent the tomatoes from falling. Generally, after 2-3 days of use, the stalk begins to thicken, the ovary expands, and the fruit is thickened. Increase the sugar content. 20-40 mg / kg of liquid medicine 蘸 eggplant flower handle, conducive to fruit preservation, early maturity.
The anti-falling market is sold as a water agent, and 25% of the anti-fallin 1 ml is 50 mg/kg of water at a concentration of 500 g. When half of the flowers of the tomatoes are open, the flowers are sprayed with 10-50 mg/kg of anti-falling pigments to prevent the flowers from falling off and improve the quality and yield. Be careful not to spray on the tender tips and leaves, and the concentration will become smaller with increasing temperature to avoid phytotoxicity. Use 50 mg/kg for 20 °C or less, 25 mg/kg for 20 °C-30 °C, and 10 mg/kg for 30 °C or more.
Naphthaleneacetic acid Take the original powder 2.5 mg and add 500 g of water to stir and dissolve. The solution concentration is 50 mg/kg. Using this concentration of naphthaleneacetic acid to spray the fruit in the flowering and bud stage of the pepper can increase the fruit setting rate, single fruit weight and fruit weight per plant, and increase yield.
2, gibberellin to take the original powder 5-10 mg dissolved in 95% alcohol and then add 500 grams of water, the solution concentration is 10-20 mg / kg. The celery plant is sprayed in the field with a solution of 10-20 mg/kg, the plant height is increased, the number of leaves is increased, and the petiole is thickened, which can be harvested one month earlier. For coriander and spinach with fast growth and short growth period, the effect is more obvious, and the yield increase can reach 10%-90%. The mixture was sprayed with 100 mg/kg of chemical solution plus 0.5% urea at the flowering stage of green beans, and the number of flowers was doubled, and the pods were increased by 4 times. The solution of 100-500 mg/kg is sprayed 1-2 days after the flowering of the cucumber, so that the melon grows fast and is not easy to turn the melon. Spray the strawberry with 10 mg/kg of liquid medicine, and spray it once a week for 3 times to increase the yield.
3, pure fresh product 2.5 grams, add triethanolammonium into the beaker, alcohol lamp heat on a small fire, stir until dissolved, add water 1000 ml solution concentration is 2500 mg / kg. Spraying onions and garlic with 2500 mg/kg of fresh green can inhibit the sprouting of fresh stems. 2-3 weeks before potato harvesting, 2500 mg/kg of liquid is sprayed in the field to prevent the potato chips from germination during storage. Spraying the leaves with a solution of 250-500 mg/kg 4-14 days before carrot and cabbage harvesting can extend the harvesting period and supply period.
4, 50% of chlormequat 50 ml of chlormequat dissolved in 50 kg of water, the concentration of the solution is 500 mg / kg. Each kilometer of seedbed is watered with 1 kg of liquid medicine, which can cultivate strong seedlings, make the plant dwarf and thick, compact plant type, and the leaves are dark green. Watering the camphor plant with 500 mg/kg of liquid medicine can make the plant body short and strong, and provide strong seedlings for planting in the greenhouse in winter.
5, than the long-term take 1 g, add a small amount of hot water to dissolve, add water to 500 ml, the solution concentration is 2000 mg / kg. The cucumber and tomato plants were sprayed with this liquid to control the length of the plant. After 5-6 days of treatment, the internodes were short and thick. After 2-3 weeks, the inhibition disappeared and growth continued.
