在毛主席革命路线指引下,在“农业学大寨”群众运动推动下,我省农业生产不断发展,涌现一批水稻高产稳产的社、队。为了研究高产稳产稻田土壤应具备的起码条件,找出一般田与高产田间土壤存在的差距,以便提供建立高产稳产稻田的土壤科学依据,我们先后调查访问13个县(市)22个公社22个大队,收集了29个县(市)55个公社58个大队土样109个。我们通过调查访问,总结群众经验,野外观察土壤环境,剖面特征和分析土壤主要理化性质等手段对高产田土壤进行研究。一、取样情况土壤化学分析取样是在上述109个样品中抽取48个,都是连续三年的高产田。这些田块实行稻——稻——麦或稻——稻——紫云英的耕作制,水稻全年亩产除二个点为1400多斤
Under the guidance of Chairman Mao’s revolutionary line and with the help of the “Dazhai Agriculture” campaign, agricultural production in our province continued to develop and a batch of high-yielding rice and clubs emerged. In order to study the minimum conditions for high and stable paddy soils to find out the gap between common field and high yielding soils in order to provide a scientific foundation for the establishment of paddy fields with high and stable yield, we investigated 22 22 communes in 13 counties The brigade collected 109 soil samples from 58 brigades of 55 communes in 29 counties (cities). We investigated the high-yielding soils by investigating and interviewing, summarizing the experiences of the masses, observing the soil environment in the field, profile characteristics and analyzing the main physico-chemical properties of the soil. First, the sampling situation Soil chemical analysis Sampling is in the above-mentioned 109 samples drawn 48, are three years of high yield field. These plots implemented rice - rice - wheat or rice - rice - milk vetch farming system, the annual output of rice except for two points to 1400 kilos
