Abstract
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...
Examples
Embodiment
[0026] Adopt the present invention to utilize wild Leymus chinensis seedlings in 2003 in Chinese Academy of Sciences Da'an Alkaline Land Ecological Experiment Station (Honggangzi Township, Da'an City, Jilin Province, China) soda saline-alkali wasteland to carry out test demonstration according to the following method, prove that the present invention is effective.
[0027] The tillering seedlings of Leymus chinensis rhizomes with a seedling height of 10-15 cm are used as transplanted seedlings. Select a saline-alkali wasteland with a pH of 10.36 (a bare-alkali-spotted plot), see Table 1 for the physical and chemical properties of the soil, and level it with a disc harrow. Imitate paddy fields to raise ridges and level them with water. After settling for 1 day, plant Leymus chinensis seedlings. The cultivation density hole spacing is 10cm×30cm, and 20cm×30cm. The number of cutting seedlings per hole is 1-5 in five ways. Keep a 1-3cm water layer or keep the soil moist for 1-3...
