Abstract:
Taking Gentiana straminea 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 straminewere 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.
