摘要
通过田间试验研究了小麦蚕豆间作条件下,两种作物对氮的吸收利用。结果表明,在小麦蚕豆间作的整个生育期内,作物的氮吸收量呈单峰曲线变化,小麦、蚕豆对氮的最大需求高峰分别在开花期和拔节期。与单作相比,小麦蚕豆间作具有明显的氮养分吸收优势。
The field experiments were conducted to study the nitrogen uptake and utilization of wheat and broad bean under the condition of two crops intercropping. The results showed that the N uptake curve of crops was a single peak during the whole growth stage, the N maximum uptake stages of wheat and broad bean were anthesis and jointing stage separately. Comparison to monocropping, intercropping had siginificant N uptake advantage.
