摘    要:利用3种不同油菜枯含量、4种不同施用量的有机肥与复合肥配比,在烟苗移栽前进行塘施,对烟株根际土壤定期取样,检测土壤样品的pH值动态变化.结果表明,在不同土质条件下,只施复合肥的根际土壤pH值随烟株生长而发生降升变化;不同油菜枯含量的有机肥与复合肥配施后,对烟株根际土壤的pH值具有微调作用,其中,以50%油菜桔含量的有机肥对土壤pH值的调节作用较明显;有机肥配施量从300~1200kg/hm2的4个不同配比对土壤pH值都具有微调作用,以有机肥配施量为600~1200kg/hm2时,对烟株根际土壤的pH值具有较明显的调节作用.

关 键 词:有机肥  复合肥  烟草  土壤  pH值

Abstract:The combination of compound chemical fertilizer and organic manure,which had three contents of rape oil cake and four dosages,were applied in soil before tobacco planting.The rhizosphere soil around tobacco root system were taken to analyze the variation trend of pH value during the whole growth period of tobacco plants.The results of pH examination indicated that the pH values were rising or reducing with the growth of tobacco plants while the compound chemical fertilizer was only used in different types o...
Keywords:Organic manure  Compound chemical fertilizer  Tobacco  Soil pH value
