Cotton ripening was
The use of ethephon to ripen cotton is an indispensable measure to increase production in late-maturing cotton fields. The correct use of ethephon to promote the bolls of bolls can make cotton bolls boil early for 7 to 10 days, increase production by 6.4% to 10.2%, and increase income by more than 100 yuan per mu. Accurately grasp the technical points when ripening cotton.
First, the need for ripening cotton fields: greed green, late maturing, post-growth, intercropping cotton fields and summer sowing cotton fields. Cotton fields that are normal for growth and development and have a tendency to premature aging should not be used, otherwise they will inevitably cause premature withering of the cotton, leading to a reduction in yield. Generally, no seedlings are used for seed breeding, otherwise the seed germination rate will be reduced.
Second, spraying time: timely spraying ethephon is the key to ripening cotton. Premature use will cause early defoliation of cotton plants, reduce the weight of bolls, poor fiber development, quality decline, yield reduction; use too late will not be ripening effect. Ethylene must be decomposed and released in an environment above 20°C to release ethylene, and dry high-temperature weather is beneficial to improve the efficacy. Generally, 20 days before frost, 80% of Qingling bells sit for 40-45 days, and spray at the highest temperature above 20°C. Specific time, Shandong Province is generally in mid-October.
Third, to grasp the amount of drugs: the ripening effect of ethephon under certain conditions depends on the amount of the drug per unit area, the greater the amount of drug, the earlier the cracking of cotton bolls, the amount of medication is too large, will affect the yield and quality of cotton. General mu with 40% ethephon agent 100 ~ 150 g is appropriate, such as cotton plants tall, dense growth can increase the dosage.
Fourth, to master the use of drug technology: In order to improve the effect of medication, and strive to uniform the cotton plant drug, especially to ensure that the cotton bolls all drug. Therefore, it is required to increase the dosage of liquid medicine when spraying, and the amount of medicine liquid per acre should not be less than 50 kg. After the medicine is applied, it should be re-sprayed if it rains within 6 hours.
