A kind of Miscanthus planting method in arid area

Abstract

The invention provides a large-scale Chinese silvergrass planting method adopted in a drought area. The large-scale Chinese silvergrass planting method adopted in the drought area is used for improving the survival rate and the transplanting survival rate at a seedling stage and comprises seedling raising and transplantation. Silvergrass seed seedling raising is performed in land the in middle ten days of the April, the daytime temperature is controlled to be 25-35 DEG C, the night temperature is controlled to be 15-25 DEG C, the humidity is controlled to be 60%-80%, and 700-1000 seedlings are cultivated per square meter. Silvergrass seedling transplantation in the land is performed from the mid-to-end of the June to the mid-to-end of the July. The large-scale Chinese silvergrass planting method is used in the extensive drought area with the climatic conditions which are not beneficial to silvergrass growing, the transplantation speed of silvergrass seedlings is improved, and large-area silvergrass planting and large-scale silvergrass popularization in the drought area are achieved, high-quality raw materials are provided for development of biomass energy source and material industry, and the effects of conserving water and soil and improving soil in ecologically vulnerable areas are played.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, and relates to a large-scale planting technology of biomass energy crop miscanthus (Miscanthus) in arid areas. Background technique [0002] Miscanthus (Miscanthus) is a perennial herb of the Poaceae family, with high biomass yield and rich cellulose content, which can be used for refining fuel ethanol and other bio-based products. Miscanthus is rich in species and widely distributed in China, and is regarded as the most suitable energy crop for large-scale planting and production in northern China; Miscanthus has a well-developed root system, which helps to maintain water and soil and improve soil; it has strong stress resistance and is less dependent on water and fertilizers , suitable for production on arid and barren marginal land, without competing for land with grain; easy to harvest and store, suitable for large-scale planting. [0003] However, it is not conducive to the growth...

Problems solved by technology

[0003] However, it is not conducive to the growth of Miscanthus in arid areas. The problems in practice are that the emergence of Miscanthus is slow, the survival rate and seedling quality are poor, and the survival rate of transplanting is low.
