Abstract

Taking three pear orchard soils with different fertilization treatments as the research objects, the dry sieving and wet sieving method were used, the effects of different fertilization treatments on the weight distribution ratio and stability of soil aggregates in pear orchards in the 0-60 cm soil layer were stuided, in order to provide reference for the rational fertilization of soil in Korla pear orchard.The results showed that, under the dry sieving conditions, compared with CK,NPK+BIO treatment significantly increased the of 0-20 cm, 20-40 cm and 40-60 cm soil layers ＞2 mm、0.25-2 mm aggregate content（P＜0.05）,the increase by 62.00%、59.98%（0-20 cm）,12.15%、22.71%（20-40 cm） and 22.40%、29.61%（40-60 cm）;significantly reduce the content of 0.053-0.25 mm and ＜0.053 mm components（P＜0.05）,the decrease by 35.98%、43.86%,48.70%、67.65% and 40.63%、33.16%,the content of DR_0.25 accounts for 70.87%,78.87% and 75.61% of the total quantity.Under the wet sieving conditions, NPK+BIO treatment significantly increased the of 0-20 cm and 20-40 cm soil layers＞2 mm、0.25-2 mm aggregate content（P＜0.05）,the increase by 47.56%、 6.15%（0-20 cm） and 28.43%、6.43%（20-40 cm）,significantly reduce the content of 0.053-0.25 mm the micro-aggregates（P＜0.05）,the reduction by 27.70% and 15.77%,the content of WR_0.25 accounted for 60.41% and 58.75% of the total quantity.In the 0-20 cm soil layer ＞2 mm mechanically stable aggregates content showed an extremely significant positive correlation with the DR_0.25 and MWD,＞2 mm water stable aggregates content showed an significant positive correlation with the MWD,GMD and WR_0.25.Compared with the control（CK）,chemical fertilizer combined with bio-organic fertilizer（NPK+BIO） could increase the content of soil macro aggregates and effective measure to improve the soil structure of pear orchards.
