The results showed that barnyard grass shoots are primary uptake situs for amides herbicides.Acetochlor is a more effective herbicide for barnyard grass shoots than for butachlor and mefenacet.Mefenacet is only especially effect for barnyard grass.

采用小杯法和盆栽法对 3种酰胺类除草剂的除草活性进行试验 ,结果表明 ,稗草幼芽是吸收酰胺类除草剂的主要部位 ,稗草幼苗对乙草胺更敏感。苯噻草胺仅对稗草有特效

The effect of biological activation of barnyard-grass on security of the rice at 1.5-leaf stage were studied when three Amides Herbicides of Butachlor,Metolachlor and Acetochlor were combined with urea through potted experiment and analysis in laboratory in the paper,respectively.The result showed that the activity of barnyard-grass inhibition enhanced notably when they were combined with urea.The mixtures of co-toxicity coefficient rose to 146.1,116.7 and 132.6,respectively.In addition,this effect increased...

The effect of biological activation of barnyard-grass on security of the rice at 1.5-leaf stage were studied when three Amides Herbicides of Butachlor,Metolachlor and Acetochlor were combined with urea through potted experiment and analysis in laboratory in the paper,respectively.The result showed that the activity of barnyard-grass inhibition enhanced notably when they were combined with urea.The mixtures of co-toxicity coefficient rose to 146.1,116.7 and 132.6,respectively.In addition,this effect increased with the dosage of three Amides Herbicides.Further more,urea can strengthened their security on the rice at 1.5-leaf stage.Its activity of rice inhibition growth of the co-toxicity coefficient was 79.1,87.5 and 67.2,respectively.

采用室内盆栽法,将3种酰胺类除草剂丁草胺、乙草胺、异丙甲草胺与尿素混用后,对抑制稗草的生物活性和1叶1心期水稻的安全性进行了研究。结果表明尿素与这3种酰胺类除草剂混用可显著提高除草剂的抑稗活性,混用后的共毒系数分别为146.1、116.7、132.6,其抑稗活性随除草剂剂量的增加趋于明显,混用后对1叶1心期水稻的安全性也显著提高,混用对水稻生长抑制共毒系数分别为79.1、87.5、67.2。

The effect of effectiveness in field of herbicides,fertilizer efficiency and the utilization ratio of nitrogen of the urea,security and agricultural properties of the rice were studied when three amides herbicides of butachlor,metolachlor and acetochlor were combined with urea through plot experiment and demonstration experimental small areas as well as laboratory analysis determination in the paper respectively.The results showed that three amides herbicides were combined with urea in the plot experiment...

The effect of effectiveness in field of herbicides,fertilizer efficiency and the utilization ratio of nitrogen of the urea,security and agricultural properties of the rice were studied when three amides herbicides of butachlor,metolachlor and acetochlor were combined with urea through plot experiment and demonstration experimental small areas as well as laboratory analysis determination in the paper respectively.The results showed that three amides herbicides were combined with urea in the plot experiment might be excellent weed control for as its stable and entirely weed-killing performance.During the rice-growing period,the total weed-killing percentage was stable over 85% and 90% in fresh weight.The mixtures could inhibit above-growth in seedling stage and stimulate rice growth during adult addition,all agricultural properties of the rice are higher obviously while reaping,the rice yield increase 13.9%,11.4% and 10.5% reparately.The utilization ratio of nitrogen of the urea increase 3.2%,6.2% and 2.2%.Further more the herbicides mixed with wea delayed trend the release time in the soil of urea and the residual effects period of herbicides more than 50 days.

通过田间小区对比试验和盆栽试验研究了3种酰胺类除草剂丁草胺、乙草胺、异丙甲草胺单用及与尿素混用对除草剂药效、尿素肥效和水稻产量性状的影响。结果表明,这3种酰胺类除草剂与尿素混用对稻田各类杂草的株防效、鲜重防效都略高于除草剂单用。对水稻的生长表现为“前控后促”的趋势,水稻收获时的各项经济性状指标都优于除草剂单用,可以提高水稻的安全性和氮素的吸收利用率,且在一定程度上延缓了尿素在土壤中的释放及延长了农药的持效期。
