Study Of Security And Effect Of Herbicides On Millet

In this article ,we had two millet Varieties in the experiment.It studied that the effect of safty and the effect of medicine in different three herbicides MaiGuNing , PuCaoJing and YiA .1 .The effect of the shape index and content factor of yield with different concentration in herbicides on millet:In the beginning of growth,it has effect on plant high,but to the autumn,different concentration of herbicides had changed normal lever;the concentration of MaiGuNing from 450 to 675g/hm2 ,it has lower with the cncentration increased;the different herbicides had promoting effctives on the spike weight and per 1000 grain weight in normal,but with the concentration differrentation,the result was not2.The effect of chorophyl content in different concentration of herbicides :it has determined the chorophyl content in Jiontng,YiA has the promotion of chorophyl content in Dungu millet and the comfortable content was 1500ml/hm2 ;the effect of MaiGuNing was not markedness;The content of chorophyl A and total chorophyl on Jingu21 millet has the trend of prophase raised and anaphase lower with the increased of YiA concentration ,but on the contrary, the chorophyl content has changed first high then lower with the increased concentration of MaiGuNing.In Booting,the Dungu millet has reduced on different concentration of herbicides,but the Jingu21 has raised at the same time,it has sensitivity to MaiGuNing.3.The effect of different concentration of herbicides on the millet:the concentration of YiA 750 ml/hm2 and 1500 have the obviousely inhabition on the Fat of Dungu millet;the effect has not significant of the Fat on Dungu millet with MaiGuNing (treatment of soil in the before germination);When the concentration of PuCaoJing herbicides is 1500g/hm2,it has restrained the content of Fat on Dungu millet;Becides the used of herbicides can bate the accumulation of the amylum.4.The effect of germination quoiety on millet in different concentration herbicides:all of the treatment,the germination quoiety had depressed.In the treatment of Dungu millet,MaiGuNing Which germination has lager than YiA and PuCaoJing's the effect of medicine;the resistance of Jingu21 millet has stronger than Dungu millet,In the speed and orderness of Jingu21 were slowly than Dungu,but germination has more orderness than Dungu.5.The studied of preventation effect on different concentration on milletrthe treatment of effection on which can restrain purslane and reduced amaranth or other weeds were good on YiA and the pro-germination of MaiGuNing milletthere were obviousely reduced effectives of restrain weeds with the concentration of PuCaoJing raising,the effect of weeds was unstablity.
