套种对油桐果实性状和经济效益影响

Effect of Intercropping Vernicia fordii with Medicinal Plants on its Fruit Characters and Economic Benefits

通过在油桐林下套种5种药材,分析不同套种模式下油桐果实经济性状、脂肪酸组分及含量和经济效益。结果表明:鲜果出鲜籽率麦冬>石蒜>玉竹>油桐纯林>桔梗>黄精;干籽出干仁率分别为麦冬>黄精>玉竹>石蒜>桔梗>油桐纯林;干仁出油率分别为麦冬>黄精>玉竹>石蒜>桔梗>油桐纯林;桐酸含量油桐+黄精、油桐+玉竹和油桐+桔梗模式较高;经济效益以玉竹最高,每667 m^2达到了14 100元,桔梗为11 560元,黄精为9 050元。

We intercropped Vernicia fordii with 5 medicinal plants and analyzed the fruit characters and economic benefits of different intercropping patterns.The results showed：the sequence of the seed rate of fresh fruits of different patterns was that Ophiopogon japonicas〉Lycoris radiata〉Polygonatum odoratum〉 CK〉Platycodon grandiflorus〉Polygonatum sibiricum;and that of the kernel rate of dry seed of different patterns was that Ophiopogon japonicas〉Polygonatum sibiricum 〉Polygonatum odoratum 〉Lycoris radiata 〉Platycodon grandiflorus〉CK;and that of the oil rate of dry kernel of different patterns was that Ophiopogon japonicas〉 Polygonatum sibiricum 〉Polygonatum odoratum 〉Lycoris radiata〉 Platycodon grandiflorus〉CK;and the paulownic acid from the patterns of Vernicia fordii＋Polygonatum,Vernicia fordii＋Polygonatum odoratum and Vernicia fordii＋Platycodon grandiflorus was higher than that of others.The economic benefit of the pattern of Vernicia fordii＋Polygonatum odoratum was the higest and arrived 14,100 yuan per 667 m2;and the secondly was that of Vernicia fordii＋Platycodon grandiflorus and Vernicia fordii＋Polygonatum sibiricum,which were 11,560 yuan and 9,050 yuan per 667 m^2,respectively.
