花生施用粉煤灰磁化复合肥效应方程及肥效研究

粉煤灰磁化复合肥是一种新型肥料，为春对花生根瘤形成和产量的影响，在汝南县砂姜黑土上进行了试验，粉煤灰磁化肥在花生上一般用量的８４０ｋｇ／ｈｍ＾２左右，粉煤灰磁化肥比对照增产２４．５％，增产７２９ｋｇ／ｈｍ＾２，比当地农民习惯施肥增产６．９％，增产２４０ｋｇ／ｈｍ＾２；比等量Ｎ，Ｐ，Ｋ混合肥增产４．７％，增产１６５ｋｇ／ｈｍ＾２，比未磁花粉煤灰复混肥增产３．３％，增产１２０ｋｇ／ｈｍ＾２。最高产量为

Study on Mathematical Modeling and Effect of Supply of Magnetized Fly- ash Compound Fertilizer on Peanut

The magnetized fly-ash compound fertilizer is a new type one, to research it's effect on peanut root nodule forming and output , we have an experiment on Shajiang black soils in Runan county. Supply of magnetized fly-ash compound fertilizer was 840kg/hm 2 on peanut. The peanut yield was 3699kg/hm 2 with supply of magnetized fly-ash compound fertilizer, 729 kg or 16.6% higher than the CK; 240kg/hm 2 or 6.9% higher than farmer's traditional fertilization practices; 165 kg/hm 2 or 4.7% higher than the same NPK compound fertilizer; 120 kg/hm 2 or 3.3% higher than the fly-ash compound fertilizer. The peanut maximum yield is 3886kg/hm 2 with 1057kg/hm 2 supply of magnetized fly-ash compound fertilizer. The peanut optimized yield is 3840kg/hm 2 with 842kg/hm 2 supply of magnetized fly-ash compound fertilizer. The result showed that the magnetized fly-ash compound fertilizer have notable effect in improvement peanut root-nodule forming and economic properties.
