【摘要】 粉煤灰磁化肥在水稻土上对水稻作物试验结果表明：粉煤灰磁化肥在水稻土上一般用量为９２６ｋｇ／ｈｍ２左右．粉煤灰磁化肥比对照增产２７．７％，增产１９７７．８ｋｇ／ｈｍ２；比当地农民习惯施肥增产１０．６％，增产８７０ｋｇ／ｈｍ２；　比未磁化粉煤灰复混肥增产５．９％，增产５０７　ｋｇ／ｈｍ２．最高产量施用粉煤灰磁化肥为１１６９　ｋｇ／ｈｍ２，水稻产量为９２５３　ｋｇ／ｈｍ２；最佳产量施用粉煤灰磁化肥为９２６　ｋｇ／ｈｍ２，水稻产量为９１３１　ｋｇ／ｈｍ２．粉煤灰磁化复混肥在改善水稻生物学及经济性状，提高叶绿素含量和光合速率方面有显著的效应．更多还原

【Abstract】 The magnetized fly-ash compound fertilizer is a new type of fertilizer. Experimental studies for the effect of this fertilizer on rice yields in Xinyang city and Gushi county was conducted. Application rate of the magnetized fly-ash compound fertilizer on rice was 953.4 kg/hm2. The rice yield was 1978 kg/hm2 or 27.7% higher than that of the CK, 870 kg/hm2 or 10.6% higher than that of farmer’s traditional fertilization practices, and 507 kg/hm2 or 5.9% higher than that of the non- magnetized fly-ash compound fertilizer treatment.更多还原
