北京农业大学于1959年进行温室水稻栽培试验时,为了理解旱地改成水田后对土壤养分及生物学活动的影响,从土壤微生物学角度配合进行了一些重点的微生物分析。初步可看出改水田后对微生物活动的影响。现将所得资料简单介绍如下。 一、试验地概况及试验方法 温室水稻土壤原为北京农业大学试验站轻质石灰性褐色土,58年10月深翻75厘米深,各层分施厩肥共82,500斤,深翻施肥后灌大水使土壤下沉后开始按一般水稻直播栽培方式种植水稻,并用湿润灌溉方式栽
Beijing University of Agriculture in 1959 greenhouse rice cultivation experiments, in order to understand the dry land into paddy fields on soil nutrients and biological activities, from the perspective of soil microbiology to carry out some key microbiological analysis. It can be seen initially that the impact of micro-biological activities after the paddy field has been changed. Now the information is briefly described below. First, the test ground conditions and test methods Greenhouse paddy soil formerly Beijing Agricultural University Experimental Station light calcareous brown soil, in October 58 deep turning 75 cm deep, a total of 82,500 pounds of manure applied to each layer, deep turn fertilization after irrigation large After sinking the soil, the rice is planted in the normal way of direct seeding rice and planted with wet irrigation
