The author found that some farmers' friends would leave the crops that had been sprayed with ethephon, which is not advisable.
Ethephon is a widely used plant growth regulator that is easily absorbed by plants and can enter the stems, leaves, flowers and fruit cells of plants. After ethephon enters the plant cells, ethylene is gradually released by decomposition, which regulates the growth, development and metabolism of the plant. It can increase effective tillering, make plants short, prevent lodging, increase female flowers, promote early fruit ripening of crops, and early results. As a result, some farmers used ethephon to spray peppers, tomatoes, watermelons, melons, and melons to promote early maturity and redness. Spray cucumbers, pumpkins, watermelons and other melons, increase the amount of female flowers, promote early fruiting, and more melons, morning market. Spray wheat and rapeseed to increase the effective tillering, so that the plants are short and strong and prevent lodging.
Undoubtedly, spraying ethephon can increase the yield of crops, but it can be planted with the seeds of sprayed ethephon seeds, especially with ethephon directly sprayed on the fruits of peppers, tomatoes, watermelon, melon, melon and other crops for ripening. Seed seeding is harmful. This is because the use of ethephon ripening shortens the natural maturity of the crop itself, so that the fruit that has not reached the maturity stage stops growing prematurely, resulting in imperfect embryo development and affecting the germination rate. According to experiments, the germination rate of naturally mature crop seeds is generally above 90%, while the germination rate of crops sprayed with ethephon is only 30% to 40%, and the highest is not more than 50%. Therefore, any crop that has been sprayed with ethephon, especially the seeds that are sprayed on the fruit, can no longer be planted, so as not to affect the production in the coming year.
