木本泥炭与减量施肥对苹果生长及土壤养分的影响

Effect of Wood Peat and Chemical Fertilizer Reduction on Young Apple Tree Growth and Soil Nutrient

试验以2年生‘望山红’苹果树为试材,设置4个处理(不施肥、普通有机肥+化肥、木本泥炭+化肥、腐植酸钾+减量20%化肥),研究木本泥炭及新型肥料对苹果生长和土壤化学性状的影响。结果表明,在施化肥的基础上增加木本泥炭和在化肥减量施用情况下增加腐殖酸钾能显著促进苹果幼树的生长和发育,促进土壤有机质的提升和土壤中磷的活化;在化肥减量施用的情况下应以腐植酸钾为主。

The experiment conducted with four treatments(no fertilizer,chicken manure compounds with chemical fertilizer,wood peat compounds with chemical fertilizer,potassium humate compounds with 20%chemical fertilizer reducing),and the two years old‘Wang Shan Hong’apple trees were taken as the material to study the effect of wood peat and its carbon based new style fertilizer on apple tree growth and soil chemical characters.The results showed that,on the basis of applying chemical fertilizer,increasing woody peat and increasing potassium humate under the condition of reduced application of chemical fertilizer can significantly promote the growth and development of young apple trees,promote the improvement of soil organic matter and the activation of phosphorus in soil;in the case of fertilizer reduction,potassium humate should be the main.
