摘　　要：磁化肥是以发电厂废物粉煤灰为主要原料,填加一定量氮肥、磷肥及其他添加剂,经磁化后制成一种新型物理化学肥料。我们用不同类型的磁化肥,采用不同的施用量在棉花上做基肥试验,经1年和3个团场试验证明,磁化肥C—NP和C—P系列4个品种作基肥可以促进棉花生长发育,提高棉花产量与质量,转化增加土壤养分,为后作提供一定土壤肥力,与对照相比增产2.1％～8.21％,经济效益每亩增收15元～36.98元,马克隆值、单纤强力成熟系数均高于对熙。C—NP和C—P系列相比,C—NP系列磁化肥好于C—P系列。在中等肥力土壤中施C—NP系列磁化肥80kg作基肥可获110kg产量,比对照增产6.47％～8.21％,每亩增收26元～36.98元。Magnetized fertilizer is a new type of physicochemical one whch is made of coal ash from heat power plant as the main raw materials,and a certain amount of nitrogenous fertilizer.Phosphate fetiliz-er and other additives.We and farm scientific stuff did basal fertilizer trials on cotton with various types of magnetized fertilizer and different application rates in three state farms of shihezi region for one year. The results proved that they promote growth of cotton,improve yield and quality of cotton,and soil nutrient,and supply a certain of soil fertilizer for next crop,When four kinds of magnetized fertilizer with C-NP and C-P series were conducted as application of basal fertilizer, Compared with control. It increased 2. 1-8. 21 % in yield and 15-36, 98 yuans in economic benefit per mu. At the same time,it also was higher than control in aspects of value, single fibre intensity and mature coefficient, In addition, C-NP series was better than C-P one. When C-NP series of magnetized fertilizer was applied to middle fertility of soil,It gave yield of 110kg,increasing 6. 47-8. 21% in yield and 26-36. 98 yuans in income per mu in contrast to control.
