施用沼气肥效果好不好?应不应大力发展?它在农村肥源建设中应当摆在何位置?只有试验对比的结果,才是最有说服力的。1981年辽宁锦州地区北镇县曹屯公社农科站,对施用沼气肥和农家肥进行了小区试验。每小区为27.5米~2,每种处理重复两次,各种肥料对比基数为亩施肥5000斤,进行单因子试验。试验用各种肥料的成分如表1。不施肥土壤成分含量即为试验地试验前状况。由表1可知试验前试验地土壤肥力中等。
Should the application of biogas fertilizer be effective? Should it be vigorously developed? Where should it be placed in the construction of rural fertilizer sources? Only the results of the experimental comparison are the most convincing. In 1981, Jinzhou County, Liaoning Province, North Town Cao Tuen commune Agricultural Station, the use of biogas fertilizer and farmyard manure community test. Each plot is 27.5 meters ~ 2, each treatment repeated twice, a variety of fertilizer base contrast fertilizer 5000 kg, for single factor test. Test with a variety of fertilizer ingredients in Table 1. The content of non-fertilizing soil is tested before the test conditions. Table 1 shows that before the test soil fertility test medium.
