在现代化的农业中,化学除莠是综合农业技术措施之一。近年来,在防除棉田杂草方面,找到了许多有效的除莠剂,例如防除棉田一年生杂草的基鸟隆和莫鸟隆,防除多年生杂草的达拉彭和阿米罗特尼阿左拉等,都有良好的效果。上述四种除莠剂于1959—60年在苏联主要棉区已进行了生产试验,试验结果证明其效果良好。 基鸟隆[3—(3,4—二苯基)—1,1—二甲基脲]为白色粉末,在水中的溶解度很低(25℃时,一公升水中可溶解42毫克),是一种稳定的化学药剂。使用时一般将粉剂加水,制成混悬液,在棉花播种前或与播种
In modern agriculture, chemical herbicide is one of the integrated agricultural technology measures. In recent years, we have found a number of effective herbicides against weeds in cotton fields, such as Alocasan and Moenlong against annual weeds in cotton fields, and dallapen and amirotinib on perennial weeds Pull, etc., have good results. The above four herbicides were tested in production in the main Soviet cotton fields in 1959-60, and the results showed that the four herbicides were effective. Chiron [3- (3,4-diphenyl) -1,1-dimethylurea] is a white powder with a very low solubility in water (42 mg dissolved in one liter of water at 25 ° C) and is A stable chemical. The powder is usually used to add water, made of suspension, cotton sowing or planting
