摘要
试验选用大同地区种植面积较大的3个板蓝根品种大叶板蓝根、小叶板蓝根、太空板蓝根,按照3∶1、4∶1、5∶1的比例套种玉米,收获时测定板蓝根和玉米籽粒产量,分析经济效益。结果表明,以山西大叶板蓝根品种按照4∶1套种玉米经济效益最高,极显著高于其他2个板蓝根套种玉米模式;3个板蓝根品种套种玉米经济效益均极显著高于单种板蓝根模式。
Three varieties of Isatis indigotica with large planting area in Datong were selected in this experiment. The yield of Isatis indigotica,Isatis indigotica and Isatis indigotica were measured at the ratio of 3∶1,4∶1,5∶1,and the total economic benefit was analyzed. The results showed that the economic benefit of maize interplanted with Shanxi Big Leaf Isatis Root was the highest according to 4∶1,which was significantly higher than that of maize interplanted with other Isatis Root. The economic benefit of maize interplanted with different Isatis Root varieties was significantly higher than that of single Isatis Root varieties.
