- 摘要:
- 利用大豆品种南豆12，在玉米套作大豆模式下，对影响玉米套作大豆复合群体产量效益的带宽比、播期、群体配置3个主要因子进行了试验研究。结果表明：以玉米窄行40 cm、宽行160 cm为玉米套作大豆最优带宽配置；在与早熟和中熟玉米套作时，6月18日是南豆12获得高产的最适播期，与迟熟玉米套作时，6月26日是南豆12获得高产的最适播期，玉米套作南豆12的适宜播种期以玉豆共生期控制在42 d以内为宜;玉米6万株·hm-2、大豆9.9万株·hm-2是玉豆两季作物双高产高效的最优复合群体配置。
- Abstract:
- We investigated the influence of field population structure,including stripe pattern,sowing date and planting density, on the yield and economic return of relay-intercropping of maize with soybean Nandou12.The results showed that yields were the highest and economic returns were the maximum when the ratio of narrow rows to wide rows for maize was 40 ∶160 cm.Under this stripe pattern,the optimum sowing date of soybean Nandou12 was June 18 and June 26 when intercropped with early- and late-mature maize,respectively.The suitable symbiotic period of maize and soybean was less than 42 days.The optimum planting density of maize and soybean were respectively 6.0×104 plants·ha-1 and 9.9×104 plants·ha-1 under the relay-intercropping condition.
