研究了固氮菌（Ａｌｃａｌｉｇｅｎｓｆａｅｃａｌｉｓ）和磷细菌（Ｂａｃｉｌｌｕｓｍａｇａｔｈｅｒｕｍｐｈｏｓｐｈａｔｉｃｕｍ）同时存在于土壤中相互促进其生长和增强生理活性的过程。并研制出解磷固氮复合细菌肥料。用该菌肥接种小麦，产量增加１０％－１７．９％，平均增产１３．２％，每亩增产小麦３０．４２ｋｇ。分析了产量构成因子，结果表明，接种的比不接种每平方米增加穗数１０．１个，每穗粒子增加１．８２，千粒重增加０．９７ｇ。 The process that both Alcaligensfaecalis and Bacillus maggotumphosphaticum coexist in the soil to promote their growth and enhance their physiological activities was studied. And developed a phosphorus-fixing nitrogen compound bacterial fertilizer. Inoculation of wheat with the fungus fertilizer, the output increased by 10% -17.9%, an average increase of 13.2% yield of wheat per acre 30.42kg. The results showed that the number of spikelets per spike was 10.1, the number of spikelets per spike was 1.82, and the grain weight was increased by 0.97g.
