摘要
以玉竹和大豆为试材,在玉竹出苗后,每隔15d采挖1次,测定玉竹不同生长时期的产量,研究玉竹的产量积累规律以确定其最佳采收期;在样地床边间作大豆,比较玉竹单作和玉竹与大豆间作二者之间的经济效益,为规模化种植提供参考。结果表明:在9月末至10月初,玉竹的产量积累达到最大值,所以该时间段为玉竹最佳采收期;玉竹与大豆间作所获得的经济效益显著高于玉竹单作的经济效益,生产上应推广玉竹与大豆间作栽培模式。
The yields of Polygonatum odoratum at different growth stages were tested with Polygonatum odoratum and Glycine max as materials.The Polygonatum odoratum was dredged every 15 days after emergencing.The ideal harvest time of Polygonatum odoratum was determined by studying the regular pattern of Polygonatum odoratumproduction accumulation.The reference for the large-scale cultivation was provided by comparing economic benefits of Polygonatum odoratum monoculture with those of Polygonatum odoratum and Glycine max intercropping which was planted at Polygonatum odoratum plots bedside.The results showed that maximum accumulation yields of Polygonatum odoratum was from the end of September to early October and the Polygonatum odoratum best harvest time was identified during this period.Economic benefits of Polygonatum odoratum and Glycine max intercropping was higher than those of Polygonatum odoratum monoculture,therefore,Polygonatum odoratum and Glycine max intercropping mode should be popularized energetically in the production process.
