Abstract:

In order to resolve the poor efficacy or phytotoxicity problems in promotion of the herbicide monosulfuron plus propazine 44% WP, adopting four factors four levels and three factors two levels orthogonal test by Duncan's new multiple range method for statistics and analysis, herbicide dose, sprinkler irrigation water volume, quality of soil preparation, soil moisture content such impact factors of comparative trials carry on research the monosulfuron plus propazine 44% WP about prevention and control weeds and millet yield influence. Results show that: seven experiment factors on the monosulfuron plus propazine 44% WP reference prevention and control weeds have important influence effect, among them, herbicide dose, sprinkler irrigation water volume, quality of soil preparation , soil moisture content or influence the most important factors of millet yield. According to yield and economic benefit, determine the monosulfuron plus propazine 44% WP economic, safe, effective prevention and control techniques of weeds in field of optimization scheme: The monosulfuron plus propazine 44% WP dose was 1800 g/hm2. Before after planting seedlings in soil treatment, plough rake land have to tightly don't loose. Soil moisture to achieve 15%. Spraying herbicide did not carry on spray irrigation, 45 days high in the effect duration control weeds in millet field, especially dicotyledonous weeds.
