Studies on Safety Aspects and Performance of Herbicides on Different Ecosystem Type Millet [Setaria Italia (L.) Beauv]

This test uses a single factor randomized block design pot experiment , two sets of pilot programs to develop a soil treatment and foliar treatment , planted 34 varieties of millet , two soil -applied herbicides Prometryne , speed - entry and three the foliar treatment herbicides Glutenins Ning received toremifene , 2,4- D of millet security and weed control effect . Determination of morphological, physiological and biochemical parameters , the resistance difference between the comparison of different ecotypes millet varieties by cluster analysis . The results show that : the five herbicides on most of the millet plant height , leaf area has a certain extent , only a handful of millet varieties role in promoting ( red five card ) . Different herbicides on physiological indices of the same kind of millet there is a difference . Most of millet have of prometryn ( 0.07g/m2 ) , a certain amount of resistance , the prometryn pharmaceutical treatment , most of the millet POD activity increased soluble sugar content increased , transpiration rate , stomatal conductance improved to some extent . 2,4-D (0.07ml/m2) on most millet POD activity has been suppressed , and the photosynthetic rate . The most millet application speed closing ( 0.015g/m2 ) in SOD activity decreased , the transpiration rate , stomatal conductance increased . The glutenin ning ( 0.05g/m2 , ) the most millet photosynthetic rate . The five herbicide early in the growth inhibition of millet chlorophyll content . With a herbicide physiological indices of different ecological types of millet varieties are different , their cluster analysis , clustering results each four categories.
