32.5% Herbs and Ethephon 1. Product Name: Early Mature 2. Toxicity: low toxicity 3. Registered crops: cotton 4. Using technology (1) Effect of 32.5% Herbs and Ethephon on cotton bolls After spraying 32.5% of the grass and ethephon in cotton, the main leaves of the cotton leaf were wilted and dried, and the ventilation and light transmission conditions were improved to promote the boll opening and bolling. The boll opening rate at 5d, 10d, 20d and 30d after treatment was 18.2%~25.5%, 32.7%~39.2%, 55.3%~58.8%, 89.3%~91.8%, and the concentrated boll opening period was 15~20d after medicine. In the ethephon treatment area applied at the same time, the boll opening rate at 5d, 10d, 20d and 30d after the treatment was 15.8%, 26.3%, 42.6%, 77.2%, and the concentrated boll opening period was 20~25d after the medicine. The boll opening period of 32.5% Herbs and Ethephon was 5~10d earlier than Ethephon, 10~15d earlier than the control, and 5d later than 100. There was no significant difference between the different amounts of 32.5% paraquat and ethephon. (2) Effect of 32.5% Herbs and Ethephon on the residual blue bell rate and cotton yield After spraying 32.5% of paraquat and ethephon, the cotton not only has the effect of promoting early bolls on mature cotton bolls, but also has the effect of prematurely cracking and bollging due to the shrinkage of bolls and shells due to the shrinkage of bolls. The residual green bell rate of 32.5% paraquat and ethephon treatment was 5.5%~6.4%, which was 26.5~27.4 percentage points lower than the control residual blue bell rate of 32.9%, and 9.3~10.2 percentage points lower than the ethephon residual blue bell rate of 15.8%. There is no significant difference between the two and the hundred. After spraying 32.5% of paraquat and ethephon in cotton, the yield of bolls was effectively improved by significantly increasing the boll opening rate and reducing the number of residual blue bells. The yield of sub-cotton of 32.5%, 100mL and 120mL per 667m2 was 261.6kg, 260.4kg and 258.8kg, respectively, which was 38.3%, 37.6% and 38.6% higher than the control 189.2kg, respectively. 234.6kg increased production by 11.5%, 11.0%, 10.4%, reaching a very significant level. Compared with Baidu, 32.5% of Herbs and Ethephon is 1.1~2.0% higher than the residual blue bell. The yield of harvested cotton is 1.6%~2.7% lower than that of Baidu, and the difference is significant. (3) Effect of 32.5% Herbs and Ethephon on cotton quality The boll weight of cotton sprayed with 32.5% paraquat and ethephon was 4.5~4.6, the litter was 37.1%~37.3%, and the fiber length was 29.9~30.7mm. There was no significant difference compared with the control and ethephon. (4) Effect of spraying 32.5% paraquat and ethephon on the cotton wool pollution After spraying 32.5% of paraquat and ethephon in cotton, the leaves of the medicine were wilted and dried, and the pollution green of the broken leaves of cottonseed was 0.9%~1.1%, which was 1.8~2.0 percentage points lower than the pollution rate of 2.9%.
