摘要:
以晋西黄土区具有代表性的苹果（Malus pumila）—花生、苹果—大豆两种果农间作模式为研究对象，对苹果—农作物间作系统中土壤水分的时空分布特征和水分效应（EM）情况进行分析，旨在为该地区间作系统水分分布模型的建立，水分生态特征的分析等提供一定的基础资料。研究表明：（1）苹果—农作物间作系统土壤含水量在不同物候期变化显著。（2）苹果—农作物间作系统中果树对作物产生的影响程度与二者之间的距离有关，离树体越近，土壤含水量越小。二维分布等值线图直观性强，对于描述间作系统土壤水分分布情况具有良好效果。（3）土壤水分效应表明果树对作物存在竞争。当土壤层次取0—40 cm时，苹果—花生和苹果—大豆间作的土壤水分效应分别为-10.54%和-12.81%；当土壤层次取0—100 cm时，其土壤水分效应分别为-11.20%和-16.83%。研究结果可为该地区土地资源合理利用和农林复合经营的可持续发展提供科学依据。
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.
