When will this year's cotton be matured? To answer this question, one must see that most of the cotton is delayed this year, at least about half a month later than usual; the second is to look at what kinds of crops such as wheat and rapeseed are grown after cotton, which can be interplanted in cotton. Using ripening technology, let cotton naturally mature. For example, the technique of ripening can be used if the cotton cultivars are urgently required to produce vegetables and other crops with higher returns. The drug used was mainly the plant growth regulator ethephon. The chemical name of ethephon is 2-chloroethyl phosphoric acid, commonly known as ripening agent. The principle of applying ethephon to cotton is that the cotton plants will release ethylene after absorbing ethephon, so that the ethylene content in the cotton bolls will increase, the activity of peroxidase will increase, the synthesis of auxin will be destroyed, and the cotton boll will transform into maturity. Ethephon production in cotton plants allows the photosynthetic products in cotton leaves to be transported in a short period of time, which promotes boll weight gain. General application of ethephon cotton, early boll 7-10 days. In order to better play the role of ethephon, the following points should be mastered in the operation technology: First, spraying time, normal years, in late September to early October, this year's cotton late, can be postponed until early October To mid-day; second, on the day of spraying, the maximum temperature is to reach 20°C or above; if it is above 20°C for several consecutive days, the effect is better; thirdly, about 80% of cotton bolls on cotton plants must reach 40 days or less. 40 days of bolls, boll weight, lint, quality will be affected; Fourth, the dosage per acre of cotton fields is 40% ethephon 100-200 ml, 50 kg against fresh water, when the temperature is high, reduce it discretionally, when the temperature is low, discretionary increase .
