Embodiment Construction

[0034] Based on the implementation of those skilled in the art, the technical solution of the present invention will be further described:

[0035] A container seedling raising method in a red sand field is mainly carried out in the arid desert steppe area where the annual precipitation in Lanzhou is below 300mm. Its steps include:

[0036] 1. Harvesting, net planting and storage of seeds

[0037] The harvest time of red sand seeds is from mid-October to mid-November every year, that is, after the fruit naturally cracks and before it falls, the standard is that the peel naturally cracks and the reddish-brown seed hair is exposed. After the collected seeds are fully dried, the leaves are first removed using a mesh sieve with an aperture of 2mm, and then the peel is removed with a mesh sieve with an aperture of 3mm, so that the purity of the seeds reaches more than 70%, and then they are stored in bags at room temperature;

[0038] 2. Selection of container:

[0039] The red ...

Abstract

The invention relates to a method for cultivating red sand seedling in container, comprising following steps: (1) choosing container; (2) preparing nutrient soil; (3) sowing in container; (4) covering for protection; (5) cultivation managing. The invention speeds up the artificial restoring process for desert and desert steppe, greatly shortens natural restore and restoring period, and possesses great ecological and social benefit.

Description

technical field [0001] The invention belongs to the technical field of crops, and in particular relates to a method for cultivating red sand seedlings in field containers. Background technique [0002] Red sand is a super-xerophytic saline small shrub belonging to Tamarix family Red sand. It has the characteristics of drought resistance, cold resistance, salt and alkali resistance, barren resistance and long growth life. The fruit is a capsule, the seed is spindle-shaped, 3-4mm long and 0.5 -1.0mm, fine and full coat. [0003] Red sand is mainly distributed in deserts and semi-desert areas in Northwest China and Inner Mongolia provinces with an annual precipitation of 60-300mm and an altitude of 500-3200m. , Qaidam Basin, Gashun Gobi, west to the edge of Junggar and Tarim Basin. It mainly grows in deserts, semi-desert piedmont alluvial plains, mountain hills, denuded hills, piedmont gravel and gravel alluvial fans, Gobi, etc. The soil is generally gray-brown desert soil, ...
