摘 要:为了探讨小麦与豆科作物的间复种高效种植模式,本试验在河西绿洲灌区,通过田间试验研究了小麦间作大豆、小麦复种毛叶苕子等5个种植模式。结果表明,以复种毛叶苕子压青处理小麦产量最高,为7175kg·hm-2;间作、复种豆科作物的处理经济效益均高于单作小麦,以小麦间作大豆根茬处理经济效益最高,为23142元·hm-2,较单作小麦增值45.6%。毛叶苕子压青处理能显著提升土壤养分含量,土壤碱解氮、速效磷、速效钾和有机质含量分别提升了3.5、0.4、12.2 mg·kg-1和2.4g·kg-1,具有较好的经济与生态效益。研究结果表明小麦间作、复种绿肥作物种植模式具有较高的经济效益,为当地绿肥作物生产提供实践指导。In order to study the effects of planting patterns about wheat inter-cropping and multiple cropping of leguminous crops. In Gansu Hexi oasis irrigation area,5 cropping pattern of wheat inter-cropping Glycine max,wheat multiple cropping Vicia villosa Roth. etc. was studied by field experiment. The results showed that: The multiple cropping Vicia Villosa Roth tillage processing the highest of wheat yield was 7175 kg·hm^- 2; intercropping and multiple cropping of leguminous crops were higher than that of wheat benefit,Wheat intercropping Glycine max the highest economic benefit,is 23142 yuan·hm^- 2,compared to sole cropping wheat added 45. 6%. Hairy Vicia villosa Roth green manure treatment could significantly improved the soil nutrient content,soil alkali hydrolyzable nitrogen,available phosphorus,available potassium and organic matter content were promoted 3. 5,0. 4,12. 2 mg·kg^- 1and 2. 4 g·kg^- 1,the economic and ecological benefits is better. The results for the wheat inter-cropping and multiple cropping had higher economic benefits,for the local produced the green manure provided the theoretical.
