| 摘 要： | 在四川盆地东北部中丘区的棕紫泥旱坡地上,研究了"麦/玉/苕"旱三熟增间大豆的经济效益和土壤生态效益.结果表明:"麦/玉/苕"间种大豆结合秸杆还田耕作,在大春粮食增产或不减产基础上,经济效益显著提高;土壤容重降低、养分提高,特别是有机质、速效磷、速效钾明显增加.认为改进种植模式与发展大豆生产相结合,是提高旱坡地综合效益的良好途径.

| Abstract: | A field experiment was conducted on the arid upland and hilly land of the brown purple soil in the northeast part of Sichuan Basin to investigate the economic and soil ecological benefits of the wheat/maize/sweet potato + soybean planting pattern.The results showed that the economic benefit increased significantly without any yield loss of the summer crops in the wheat/maize/sweet potato planting pattern in combination with straw application to the soil,and soil bulk density decreased and nutrients increase... |
