摘要
磁混肥与等量纯养分或磁灰相比，能显著提高小麦产量；每盆施磁混肥７．４ｇ，产量最高。在一定范围内，随着磁混肥用量的增加，种子粗蛋白含量、小麦硝酸还原酶活性和叶绿素含量增加，而过氧化氢酶活性降低。
In a pot experiment,normal fertillzers(NPK and microelements)and pre-magnetized coal fly-ash were applied separately or in combination to wheat.Magnetic mixture fertilizer(normalfertilizers in combination with pre-magnetized coal fly-ash)significantly raised grain yield comparedwith the other two treatments,The rate of 7.4y/pot(diameter being 20 cm)gave the highest yield.With increasing rates,the crude protein in the seed and n itrate reductase activity and chlorophyllincreased and catalase activity dec reased.
