Intercropping can result in large yield increases compared to mono-cropped systems. It is used extensively in China and could be an option for sustainable land-use in Australia. Belowground interactions between intercropped crop species may be important for the yield increase, but they are poorly understood, especially with regard to nutrient availability and soil biology. We will combine the field experience in intercropping systems of the Chinese scientists with the expertise of the Australian scientists in plant nutrition and rhizosphere ecology to characterise chemical and biological interactions in the rhizosphere governing nutrient availability and the competitive ability of intercropped species.

与单作系统相比，间作可导致产量大幅增加。它在中国被广泛使用，并可能成为澳大利亚可持续土地利用的一种选择。间作作物物种之间的地下相互作用可能对产量增加很重要，但人们对它们的了解很少，特别是在养分供应和土壤生物学方面。我们将联合收割机结合中国科学家在间作系统方面的田间经验和澳大利亚科学家在植物营养和根际生态学方面的专门知识，研究根际化学和生物相互作用对间作物种养分有效性和竞争能力的影响。
