磁处理土壤对小麦生长的影响

Effect of Magnetized Soil on Wheat Growth

研究了不同磁极化强度处理土壤对小麦生长的影响。结果表明:磁处理土壤上生长的小麦在苗期的 长势和收获期的生物学性状明显好于在未处理土壤上生长的小麦,尤以低量施肥条件下磁处理土壤对小麦 生长影响显著。苗期以100 mT处理效果较好,苗干重低肥条件下较对照增加8.8％。正常施肥时增加 13.30％。3种强度磁处理之间对小麦生物学性状影响差异不显著,但与对照差异显著(P<0.05)。磁处理土 壤提高了作物苗期、收获期对氮、磷、钾养分的吸收能力,苗期两种施肥量对磷吸收影响较大;收获期以常规施 肥对氮吸收影响较大。

The effects of soil magnetization on wheat growth were studied. The results show that growth and biological characters of wheat planted in magnetized soil during seedling and harvest stages are better than those of wheat growing in untreated soil, and the effects of low fertilizer application are more evident than those of conventional fertilizer application. Suitable magnetic field intensity of 100 mT during seedling stage has significant effects on growth of wheat, the dry weight of which increased by 8.8% under low fertilizer application compared with the control and by 13.30% under conventional fertilizer application . Magnetization of three intensities show no significant effects on biological characters of wheat, but the difference is significant compared with the control ( P < 0.05). Magnetized soil increases soil's capacity of absorbing nitrogen, phosphorus and potassium. Among the three main nutrients, the effect of two fertilizer applications on phosphorus absorption during seedling stage is greater, and the effect of conventional fertilizer application on nitrogen absorption at harvest stage is the greatest
