摘　　要：粉煤灰磁化肥在大豆上试验表明：粉煤灰磁化肥在大豆上一般用量为４９ｋｇ／６６７ｍ２左右。粉煤灰磁化月巴比对照增产２５．９％，增产２３．７ｋｇ／６６７ｍ２，比当地农民习惯施肥措施增产 １５． ２％，增产 １５． ２ｋｇ／６６７ｍ２；比等量 Ｎ，Ｐ，Ｋ混合肥增产 ４． ５％，增产４． ９ｋｇ／６６７ｍ２，比未磁化粉煤灰复混肥已增产 ２· ４％，增产 ２· ８ｋｇ／６６７ｍ２。最高产量施用粉煤灰磁化肥为 ６６．４ｋｇ／６６７ｍ２。大豆产量为 １３０．３ｋｇ／６６７ｍ２；最佳产量施用粉煤灰磁化肥为 ４９ｋｇ／６６７ｍ２，大豆产量为 １２７．１８ｋｇ／６６７ｍ２。The magnetized fly-ash compound fertilizer is a new type fertilizer one. Experimental study on effect of this fertilizer on soybean root nodule formation and yield on Shajiang black soils in Nanyang county was conducted. Application rate of magnetized fly-ash compound fertilizer on soybean was 49kg/667m2 Soybean yield was 1 14. 9kg/667m2 by applying magnetized fly-ash compound fertilizer. It was 23. 7kg or 25. 9% higher than the CK's; 15. 2kg/667m2 or 15. 2% higher than farmer's traditional fertilization practices'; and 4. 9kg/667m2 or 4. 5% higher than the same amount of NPK compound fertilizer' s; and 2. 8kg/667m2 or 2. 5 % higher than the non-magnetized fly-ash compound fertilize r' s. The soybean maximum yield came to be 130. 3kg/667m2 with applying 66. 4kg/667m2 of magnetized fly-ash compound fertilizer. The optimum amount of application was 49kg/ 667m2 of magnetized fly-ash compound fertilizer which derived 127. 18kg/667m2 soybean yield. The result shown that the magnetized fly-ash compound fertilizer have notable effect on improvement of soybean root-nodule formation and economic properties.
