Abstract

The invention provides a PopuIus euphratica Oliv cultivation method comprising the following steps: 1, seed collection; 2, seed pretreatment; 3, seed threshing; 4, seed retreatment; 5, seedling bed preparation; 6, sowing; 7, post-sowing management; 8, seedling stage management: watering and fertilization, weeding and thinning seedlings, insect disease control, nursery stock transplanting and overwintering protection; 9, nursery stock outplanting. The PopuIus euphratica Oliv seeds processed by the method can improve the germination capacity, and seed processing cost can be saved, thus solving the problems of slow seed germination and untidiness of seedling emergences; seedling growing difficult conditions by a conventional method can be simplified in seed breeding, the process is fast, and seed seedling growing popularization can be performed in production.

Description

Technical field [0001] The invention relates to the technical field of methods for raising seedlings of Populus euphratica, in particular to a method for cultivating Populus euphratica. Background technique [0002] Populus euphratica (PopuIus euphratica Oliv), also known as Populus heterophylla and Populus euphratica, is the only tree species in the populaceae family that can grow naturally in deserts and Gobi areas. It is located in Anxi, Dunhuang, Yumen, Jinta, Jiuquan and Gaotai in Gansu Province. Counties (cities) such as Minqin and Minqin have natural Populus euphratica forests. The trunk of Populus euphratica is straight, the bark is gray-brown, and the branches are smooth, yellow-brown, with stripes, cylindrical or slightly square. The leaf shape is changeable. The leaves of seedlings and saplings resemble willow leaves. The upper part of the crown of large trees is mostly oval-lanceolate, and the middle and lower parts are triangular or kidney-shaped, with thick serrate...
