为防除野燕麦危害,我们在西安市化工研究所的支持下,在城关公社西关大队四队和金渠公社河底大队三队,进行了试验。“新燕灵”药剂由北京市化工研究所试制。每立升含成品200克。在小麦拔节和孕穗期叶面喷雾,选燕麦较多的麦田作试验,分试验区和对照区。试验结果是:河底大队三队试验面积0.2亩,喷药期1月21日,每亩用药量0.6斤,加水100斤。小麦正值返青期,品种丰产3号,5月15日田间调查防治效果63.1％。城关公社西关大队四队试验面积2
In order to control the damage of wild oats, with the support of the Xi’an Institute of Chemical Industry, we carried out experiments in the four teams of the Western Border Brigade of Chengguan Commune and the third team of the river bottom brigade of Jinqu Commune. “Xin Yan Ling” pharmaceutical trial by the Beijing Institute of Chemical Technology. Per liter with 200 grams of finished products. In the wheat jointing and booting leaves foliar, wheat field more oats selected for testing, sub-test area and control area. Test results are: River Brigade three teams test area of 0.2 acres, spraying January 21, the amount of 0.6 kg per mu, add water, 100 pounds. Wheat is turning green, the variety of high yield on the 3rd, May 15 field investigation prevention and control effect of 63.1%. Chengguan commune West Gate Brigade four test area 2
