为了研究以化学方法防除棉田杂草的效果,我们于一九六一至一九六三年在阿塞拜疆棉作科学研究所中央试验站所属的沙姆霍尔斯克、卡苏姆一伊斯马伊洛夫斯克和萨此拉巴德斯克生产管理处进行了研究。除莠剂在苜蓿地中分两个时期使用:秋季翻耕前和棉花苗期。 秋季翻耕前使用的除莠剂是2.4-D,用量为每公顷有效成分2公斤。十月底用拖拉机牵引喷雾,十一月中旬翻耕,深度28—30厘米。对照区系先浅耕6—8厘米,而后翻耕28—30厘米。
In order to study the chemical control of weeds in cotton fields, we investigated the effects of weeds in cotton fields from 1961 to 1963 at Shams Horsk, Kashmir-Ismayi, a central experimental station of the Cotton Research Institute of Azerbaijan Lovesk and Sara Rabbinsk Production Management conducted a study. Herbicide use in alfalfa in two periods: before the autumn tillage and cotton seedlings. The herbicide used before autumn tillage was 2.4-D in an amount of 2 kg per hectare of active ingredient. By the end of October tractor spray, mid-tillage in mid-November, the depth of 28-30 cm. The control area first shallowly plowed 6-8 cm, then plow 28-30 cm.
