Taking Xanthoceras sorbifolia Bunge and Ulmus pumila L. seeds as material, the germination test of the direct seeding afforestation and nutritive bowl seedlings cultivation technology were studied. By monitoring the germination of the two species'seeds under the conditions of different water and salt, the drought and salt resistance level of germination will be revealed. It can provide the theory basis for finding the soil water and salt qualification fitting X. sorbifolia and U. pumila direct seeding. The ...
