Abstract

Abstract: Through the field plot test for monocropping corn, monocropping potatoes and corn intercropping potato, collection of corn in different development stages of the three （elongation stage, bell stage, tasseling stage） of root and soil, and determine the organic acid and total sugar in root exudates. And soil aggregate status, analysis of root characteristics and root exudates on soil aggregates. The results showed that the root length, root volume and root surface area of intercropping maize were significantly higher than those of monoculture maize（P<0.05）. The total sugar and organic acid secreted by maize roots increased with the growth stage. Intercropping significantly increased the total sugar and organic acid secreted by maize roots （P<0.05）. At tasseling stage, the water stable aggregate content（R_0.25） of>0.25 mm in intercropping maize was significantly increased by 8.17% compared with that of monoculture maize（P<0.05）. The geometric mean diameter（GMD） of aggregate was significantly increased by 12.24%（P<0.05）, and the fractal dimension（D） was significantly decreased by 1.09%. The percentage of aggregate destruction（PAD） was significantly reduced by 26.08%. The total sugar and organic acid secreted by the root system of maize were significantly correlated with R_0.25, GMD, D and PAD（P<0.01）. Therefore, maize intercropping potato can change the characteristics of maize root system, increase the total sugar content and total organic acid content secreted by maize root system, and then improve the stability of soil aggregates.

Key words: maize, different planting patterns, red soil of sloping cultivated land, soil aggregate
