在欧洲、澳洲及世界其他部分已广泛应用2—氯乙基三甲基氯化氨(CCC)作为小麦防倒化学药剂,从而获得增产。据报导,CCC对小麦及一些作物有调节生长的作用。主要是使茎杆矮壮,减少因倒伏所造成的危害,另外一些对产量的有利影响是延长叶子的衰老过程,改善植物水分供应能力等。本文为美国密西西比州的田间试验结果,主要讨论CCC的施用时期,施用量,以及在目前施氮水平不断提高,氮肥超过100公斤/公顷的情况下CCC对小麦的作用等问题。试验分别于1968—1972年进行,采用拉丁方或随机区组设计,品种为“科克尔65—
2-Chloroethyltrimethylammonium chloride (CCC) has been widely used as a chemical anti-dumping agent in wheat in Europe, Australia and other parts of the world to increase production. It has been reported that CCC plays a role in regulating the growth of wheat and some crops. Mainly to make stalks stout to reduce the harm caused by lodging, and some of the beneficial effects on the yield is to extend the leaf aging process, improve the plant’s water supply capacity. This article is a field experiment in Mississippi, USA, focusing on the timing of CCC application, the amount of CCC applied, and the role of CCC on wheat under current N application rates of more than 100 kg / ha. Tests were carried out in 1968-1972, using Latin square or random block design, the variety is "Corkel 65-
