- Abstract:
- Targeting two typical fruit-crop intercropping models, i.e. apple(Malus pumila)-peanut and apple-soybean in the Loess Plateau of western Shanxi Province as test sites, the spatiotemporal distribution and effect(EM) of soil moisture in apple-crop were studied in order to provide the basic references for constructing the model of soil moisture distribution and analyzing the water ecological characteristics of fruit-crop intercropping in this region. The results showed that: (1) the soil moisture variation of apple-crop intercropping was very significant in different phonological stages; (2) the influence degree of apple trees on crops related to the distance between apple trees and crops in apple-crop intercropping system, and the soil moisture decreased with the decreasing distance from apple tree rows, two dimensional distribution of contour map presents a very strong visual impression, it obtained good results in terms of expressing the spatial structural characters; (3) the values of soil moisture effect showed that it existed moisture competition between crops and trees in apple-crop intercropping system, the values of EM in apple-peanut and apple-soybean intercropping system were -10.54% and -12.81% in layer of 0—40 cm, respectively, while those were -11.20% and -16.83% in layer of 0—100 cm, respectively. This study could provide a scientific basis for land resource rational utilization and agroforestry management for sustainable development in this region.
