为了研究幼龄苹果(Malus pumila)×大豆(Glycine max)间作系统中土壤水分、养分的空间分布特征及其对大豆生长和产量的影响,选取晋西黄土地区具有典型代表性的幼龄苹果×大豆间作模式作为研究对象,对苹果×大豆间作系统及大豆单作系统(对照)的土壤水分、养分含量进行了定位监测。结果表明:(1)在垂直方向上,土壤水分含量随着土壤深度的增加而逐渐增加,土壤养分含量随着土壤深度的增加而逐渐减小;(2)在水平方向上,随着与树行距离的增加,土壤水分含量呈现递增的分布特征,土壤养分含量呈现高低高的分布特征;(3)与大豆单作系统相比,间作系统的土壤水分、养分含量出现不同程度的降低,整体上均表现为负效应;(4)苹果×大豆间作系统中苹果树与大豆间的土壤水分、养分竞争对大豆植株生长发育造成了较大影响,土壤水分含量、速效磷含量和全氮含量是影响大豆产量的主要因素,影响的主要区域在苹果树行两侧1.5 m的范围内;(5)建议采取适当的调控和管理措施缓解种间水肥竞争提高大豆的产量,以获取更多的经济收益。
為瞭研究幼齡蘋果(Malus pumila)×大豆(Glycine max)間作繫統中土壤水分、養分的空間分佈特徵及其對大豆生長和產量的影響,選取晉西黃土地區具有典型代錶性的幼齡蘋果×大豆間作模式作為研究對象,對蘋果×大豆間作繫統及大豆單作繫統(對照)的土壤水分、養分含量進行瞭定位鑑測。結果錶明:(1)在垂直方嚮上,土壤水分含量隨著土壤深度的增加而逐漸增加,土壤養分含量隨著土壤深度的增加而逐漸減小;(2)在水平方嚮上,隨著與樹行距離的增加,土壤水分含量呈現遞增的分佈特徵,土壤養分含量呈現高低高的分佈特徵;(3)與大豆單作繫統相比,間作繫統的土壤水分、養分含量齣現不同程度的降低,整體上均錶現為負效應;(4)蘋果×大豆間作繫統中蘋果樹與大豆間的土壤水分、養分競爭對大豆植株生長髮育造成瞭較大影響,土壤水分含量、速效燐含量和全氮含量是影響大豆產量的主要因素,影響的主要區域在蘋果樹行兩側1.5 m的範圍內;(5)建議採取適噹的調控和管理措施緩解種間水肥競爭提高大豆的產量,以穫取更多的經濟收益。

In order to investigate the spatial distribution characteristics of soil moisture and soil nutrients in young apple (Malus pumila)-soybean (Glycine max) intercropping system and its influence on soybean growth and yield, young apple-soybean intercropping pattern which was typical and representative in loess region of west Shanxi Province was studied and soil moisture and soil nutrients in apple-soybean intercropping system and soybean monoculture system were monitored separately for comparison. The results showed that: (1) in vertical direction, with the increase of soil depth, soil moisture increased while soil nutrients decreased; (2) in horizontal direction, with the increase of distance between crops and trees, soil moisture increased while the distribution of soil nutrients was high-low-high; (3) compared with soybean monoculture system, soil moisture and soil nutrients in intercropping system were both lower. It had negative effect in general; (4) the competition for soil moisture and soil nutrients between apple tree and soybean in apple-soybean intercropping system had a great influence on soybean growth. Soil moisture content, available phosphorus content and total nitrogen content were main factors influencing soybean yield and the range of main influence scope were 1.5 m from the apple tree; (5) in order to achieve more economic benefits, appropriate regulation and management measures should be taken to alleviate competition for soil moisture and soil nutrients between species and to increase soybean yield.
