本试验于1979—1981年进行.在同质、同量和同期的条件下进行发酵试验和水稻肥效对比试验,目的在于通过提高有机肥的矿化度与有机、无机肥适当配合的途径来满足本地区双季稻早发、早熟、稳产和高产的要求.一、试验设计和方法(一)田间试验是本研究的主要组成部分.三年来,先后在上海、松江、奉贤、嘉定、南汇等县的部分社队进行多重复的双季稻肥效对比,总面积约75亩,小区面积为0.25—0.30亩.试验的基本处理类型是:1.沼肥与堆沤肥(有
The experiment was carried out from 1979 to 1981. The experiments of fermentation and rice fertilizer efficiency under the same, same and same conditions were carried out to improve the salinity of organic fertilizer and the proper combination of organic and inorganic fertilizers Pre-season, stable yield and high yield of double cropping rice in this area I. Design of experiment and method (I) Field experiment is the main part of this research, and in the past three years, it has been established in Shanghai, Songjiang, Fengxian, Jiading and Nanhui etc. A number of communes and counties in the county carried out a comparison of fertilizer efficiency of double cropping rice with a total area of about 75 mu and a plot area of 0.25-0.30 mu. The basic treatment types of the trial were:
