摘 要:以麻花艽为试材,将麻花艽与青海传统农作物小麦、油菜、蚕豆套种,观察不同套种作物对麻花艽出苗数、保苗数、生物量及有效成分含量的影响,以期为麻花艽栽培套种提供科学依据。结果表明:与小麦套种的麻花艽出苗数、保苗数高,而与蚕豆、油菜套种的麻花艽出苗数、保苗数低;小麦播种量在18kg/667m2、油菜保苗1.2万株/667m2、蚕豆保苗1.7万株/667m2时,套种作物产量高、麻花艽出苗数多,根长更长、根茎粗更粗、单株根鲜重和根干重更重。故青海农业区种植麻花艽时,应以小麦、青稞等禾谷类作物作为套种的首选作物。Taking Gentiana strarninea as material, the effect of different intercrops wheat, rape and broad bean on the emergence number,seedling survival number, biomass and active ingredient content of Gentiana strarnine were studied in order to provide scientific basis for intercrops with Gentiana straminea. The results showed that Gentiana stramine intercropped with wheat enjoyed higher emergence number and seedling survival number compared with those intercropped with rape and broad bean. Moreover, when wheat was planted with the seeding quantity of 18 kg/667m2 , rape and broad bean with the preserving seedling of 12 000/667m2 and 17 000/667m2 respectively, the intercrops presented higher yields and Gentiana straminea had larger emergence number,longer roots, thicker rhizome, heavier single fresh weight and dry weight. Recommendations Qinghai agricultural areas that grain crops like wheat and highland barley should be chosen as the preferred intercrops with Gentiana straminea.
