Abstract:

In order to explore the safe application dosage of effective herbicide under the condition of field UAV (unmanned aerial vehicle) spray control, the effects of different herbicide treatment levels on the growth of wheat variety ‘Yumai 49’ under the condition of field UAV spray control were simulated by field plot experiment and constant spray method. The results showed that under the herbicide treatment with the recommended dosage, 2 times dosage and 4 times dosage, the chlorophyll content, N content and photosynthetic rate of flag leaves of wheat, plant height and leaf rust disease index significantly decreased. The chlorophyll content and N content of flag leaves had no decrease but increased when 3.6% disulfonate-meiodarone WDG 2 times dosage and 15% acetylide WP 4 times dosage were applied. The yield of the plot test at the recommended dosage and the multiple times dosage showed an increase, but when the dosage reached 4 times, the yield decreased significantly.

Key words: herbicide, Yumai 49, constant spray method, field UAV, growth effect
