2甲4氯除草肥对胡麻的安全性试验研究

Experiment in the Effect of Herbicide-fertilizer on the Linseed

采用盆栽试验和完全随机的方法,研究了2甲4氯除草剂与肥料混用在胡麻田中的安全性,对不同浓度2甲4氯除草肥处理的胡麻及其模拟杂草的出苗数、株高、鲜重等形态指标及胡麻的硝酸还原酶、过氧化物酶(POD)活性2项生理指标进行了测定分析。结果表明:2甲4氯用量为1.125 kg/hm2时,可与肥料混用作为胡麻田良好的除草肥。

The application techniques of herbicides MCPA mixed with fertilizer in the linseed field were experimented through the completely random design. In this paper,the safety to the linseed and the contcolling effect on weeds were researehed.Morphological and physiological indicators of the linseed in different Herbicide-fertilizer densities were determined and analyzed, inluding the rate of emergence, crop height, weight, level of nitrate reductase and level of POD. The results indicated that MCPA （1.125 kg/hm^2）mixed with fertilizeras Herbicide-fertilizer in the linseed were safety.and better.
