Experimental Study on Application of Fly Ash in the Dump reclamation of agriculture
LIU Shan-lin
Abstract：In the study of dump agricultural reclamation,fly ash was used to improve soil of dump land ,and the millet was selected as the crops for field trials.Analysis on the physical and chemical properties of soil ap-plied after row of fly ash,measured on the millet plant height,ear length,kernel number per spike,1000 grain weight,Yield per mu.The determination results show that,after applying fly ash,soil properties were improved,increased the content of organic matter and available nutrients,nutrient in soil,cation exchange ca-pacity increased,reduce the content of calcium carbonate.When fly ash soil,increase plant height in favor of millet,the amount of fly ash applied effect on plant height was not obvious;fly ash has little effect on the spike length and 1000 grain weight;fly ash applied amount bigger,particle number per ear,yield is high.Fly ash,farm manure,chemical fertilizer and applied into the soil,improve soil fertility and crop growth condi-tions and the effect is more obvious;fly ash used in moderation will not cause heavy metal pollution in soil.
