Example Embodiment

[0025] Example

[0026] Using the present invention, wild Leymus chinensis seedlings were tested and demonstrated at the Da'an Alkali Land Ecological Experiment Station of the Chinese Academy of Sciences (Honggangzi Township, Daan City, Jilin Province, China) in 2003 according to the following methods, which proved that the present invention has significant effects.

[0027] Tillering seedlings of Leymus chinensis roots with a seedling height of 10-15 cm were used as transplanted seedlings. Choose a pH of 10.36 saline-alkali wasteland (bright-board alkali patch plot), and see Table 1 for the physical and chemical properties of the soil. Use a disc harrow to level it. Imitate the paddy field method to raise the ridge and level it with water. Planting Leymus chinensis seedlings after 1 day of settlement. The cultivation density is 10cm×30cm and the hole spacing is 20cm×30cm. The number of cutting seedlings per hole is 1-5 plants in five ways. Keep a 1-3cm water layer or keep the soi...

Abstract

A method for restoring and recultivating the vegetation of Aneurolepidium Chinese on the soda-type saline-alkaline land includes choosing the seedlings of Aneurolepidium chinese, plough by 5-15 cm in depth, flood irrigation, leveling, making ridges or beds, transplanting by a certain density, and irrigation.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to the planting technology of forage grass, in particular to a method for restoring and rebuilding Leymus chinensis vegetation in soda saline-alkali land. Background technique [0002] Leymus chinensis belongs to rhizome-type perennial grasses and is the king of grasses. It is widely distributed in the eastern part of the Eurasian steppe region, and is mainly distributed in the northeast and eastern Inner Mongolia in China. Leymus chinensis is the dominant species of grassland in this area of ​​China. It has high nutritional value, wide adaptability, strong stress resistance, and ecological persistence of cold tolerance, drought tolerance, and salt-alkali tolerance. It is an excellent forage grass for desertification and alkali control. Leymus chinensis is also a dominant industry in China. The market potential of Leymus chinensis hay at home and abroad is huge, and the see...
