How to use ethephon, a plant growth regulator? Ethephon is a broad-spectrum organophosphorus low-toxic plant growth regulator that promotes ripening, which can enter the plant through leaves, bark, fruits and seeds, and then transmit to the active parts and release ethylene. It can promote fruit ripening and coloring, promote leaf and fruit shedding, dwarf plants, change the ratio of female and male flowers, induce crop male sterility and so on. Ethephon sold in the market is also known as Total Harvest, Gao Xin, Guoyan, Fast ripening, ripening, Qingshu, early Sweet Red, Guoguang, Laiya, Zhuangbiao, Prosperity, prosperous production, High Autumn. Ethephon can be widely used in tomato, cucumber, pumpkin, melon, tobacco, cotton, rice, corn, wheat, sugar beet, sugar cane, apple, pear, grape, peach, persimmon, banana, pineapple, rubber and other plants. The main results are as follows: 1. The green fruit of tomato near maturity can be sprayed with 40% water agent 800Me 1000 times liquid, which can promote fruit ripening and change color earlier. 2. Cucumber and pumpkin can increase female flower and yield by spraying 40% water agent 2000Mel 3000 times at the fourth leaf stage of seedlings. 3. Muskmelon can promote the formation of bisexual flowers and increase the yield by spraying 40% water agent 800 times at the third leaf stage of seedlings. 4. During the harvest period of tobacco, 40% water agent 1000Mel 1200 times liquid is sprayed, which can accelerate ripening and improve the quality of tobacco leaves. 5. During the boll opening period of 70% Mel 80% cotton, 40% water agent 300 Mel 500 times liquid is sprayed, which can promote boll boll opening and increase cotton yield. 6. The rice can regulate growth, dwarf and strengthen seedlings and increase yield by spraying 40% water agent 600 / 800 times at the seedling 5-Mel 6-leaf stage (15 Mel 20 days before transplanting). 7. During the small trumpet period, corn was sprayed with 40% water agent 10 ml / mu and 30 kg water / mu, which could regulate the growth and increase the yield. 8. Spraying 500 / 700 times of 40% water agent from booting stage to heading stage can lead to male sterility (mostly used in breeding). 9. The sugar beet can increase sugar content and yield by spraying the whole plant with 40% water agent 800 times liquid for 40 days before harvest. 10. The sugarcane was sprayed once with 40% water agent 500 times solution 35 days before harvest, which could increase the sugar content and improve the quality. 11. In the early stage of rapid shoot growth of young trees, spraying 40% water agent 200 Mel 400 times solution can inhibit the vigorous growth of new shoots, increase the proportion of short branches, promote flower bud differentiation, dwarf the crown, and bear fruit earlier. Spraying the fruit with 1000 times of 40% water 30 days before fruit harvest can promote sugar conversion, early coloring and other ripening effects. 12. The pear was sprayed with 5000 times solution of 40% water for 30 days before harvest, which could promote fruit ripening. 13. In the initial stage of berry ripening, the grape can promote fruit coloring and early ripening by spraying 1000 Mel 2000 times solution once, but when the concentration is high, it is easy to cause fruit drop. 14. Spraying peach fruit with 5000 times of 40% water in the middle stage of hard core can ripen 3 Mel 4 days earlier, and the coloring is early and neat, but the fruit is soft. 15. After persimmon harvest, spray the fruit with 40% water agent 500 times liquid, which can promote the fruit to change color and accelerate ripening. 16. After the banana harvest, spray the fruit with 40% water agent 500 times liquid, which can promote the fruit softening and increase the sweetness. 17. Pineapple can promote flowering by spraying 40% water agent 500 times liquid 15 days before flowering. Spraying with 40% water agent 500 times liquid for 2 weeks before ripening can promote ripening and the mature period is neat. 18. During the cutting period of more than 15-year-old trees, the lower part of the cutting line of the tree is scraped off 4 cm of dead skin, and then 40% water agent 5mi 10-fold solution is applied, which can increase the secretion of latex. 20 hours after application, the secretion of latex increases sharply, and the efficacy can last 45 days and 90 days. It is suggested that ethephon is strongly acidic and can not be mixed with alkaline substances or diluted with alkaline water. The dosage should be increased at low temperature and decreased at high temperature. The drug has a strong irritating effect on the skin and eyes, so pay attention to safety protection when using it.
