Promote fruit ripening
Experiments have shown that fruit produces ethylene during natural maturation. Ethylene can regulate a series of activities such as enzyme, nucleic acid and respiratory metabolism in fruits, and promote fruit ripening. When ethephon solution infiltrates into the plant, ethylene is released at different rates depending on the pH of the cells, which accelerates fruit ripening.
Tomato treatment method is the conversion of the fruits of the red fruit has not turned red, the concentration of 2000 to 4000 mg / liter, can mature 4 to 6 days earlier, but more laborious. If echinacea is sprayed on the plants prior to transformation, red ripening can be carried out 5 to 6 days earlier, but the concentration should be lower, preferably 500 to 1000 mg/l, otherwise yellow leaves and fallen leaves will be easily caused.
In the case of discoloration of the pericarp of the pepper, the use of ethephon at a concentration of between 1,000 and 4,000 mg/l impregnates fruit, which can accelerate fruit ripening and color transformation. 1000 mg/l ethephon can also be used to ripen in the field, but it is easy to cause defoliation.
For watermelon, ejaculating 300 to 500 mg/L of ethephon before the fruit is fully grown and unripened can make the fruit mature 5 to 7 days earlier. Since the watermelon has a large fruit, only the fruit is sprayed when spraying, and generally it does not cause Phytotoxicity. Promote female flower differentiation
Melon vegetable crops are different plants of male and female plants. In the process of male and female flower differentiation, in addition to the main factors of gene expression in cultivars, different hormone levels will affect gender differentiation. Melon vegetables in the undifferentiated flower buds using ethephon treatment can significantly increase the number of female flowers, generally 150 mg / l ethephon in the cucumber 1 to 5 leaves, pumpkin 1 to 4 leaves, melon 2 leaves in the foliar spray 1 ~ 3 times. Cucumber 1 to 3 leaves when sprayed 50 ~ 250 mg / l ethephon 1 ~ 3 times, can play a role in killing males, used for cucumber seed production in the field.
Promote dwarfing of plants
Spraying 240 to 960 mg/l ethephon at 1 to 4 leaves such as cabbage, celery, carrot, radish, eggplant, tomato, and squash will cause the plant to grow slowly and then stop growing. Break the plant's dormancy
Ethephon has the effect of breaking the dormancy and promoting germination. For example, soaking the potatoes with 50-200 mg/L ethephon can increase the number of buds and treat ginger, which can promote sprouting and increase branching.
At present, ethephon on the market is mostly water-based, and there are many manufacturers. In production, special attention must be paid to checking the concentration of products produced by different manufacturers. Spraying must be strictly diluted as required.
