氯甲嗪是我国七十年代蓬勃兴起的硝化抑制剂主要研制产品之一。在多种旱作物和水稻上做过许多田间试验,得到不少有益结果。为进一步探求其对水稻氮素利用率的作用和有效施用条件,1980年在苏南吴江县和武进县进行了田间N~(16)微区试验和田间小区试验。试验用药剂氯甲嗪由安徽省蚌埠市化工研究所提供。处理和方法: 试验设在吴江县农科所和武进县运村公社、奔牛公社。土壤均为发育在黄土状母质
Chlormetrine is one of the main developed products of nitrification inhibitor which is booming in our country in seventies. Many field trials have been conducted on many types of dry crops and rice and many beneficial results have been obtained. In order to further explore its effect on nitrogen utilization rate and effective application conditions of rice, N 16 micro-field experiments and field plot experiments were conducted in Wujiang and Wujin counties of southern Jiangsu in 1980. Chlormetrizine was supplied by Bengbu Chemical Institute of Anhui Province. Treatment and methods: The experiment was located in Wujiang County Agricultural Institute and Wujin County Yuncun commune, Benniu commune. Soil are developed in loess-shaped parent material
