Chinese silvergrass propagation method at Yellow River Delta region in autumn

Abstract

The invention relates to the field of plant propagation, and mainly provides a method for large-scale asexual propagation of field Chinese silvergrass through stem cutting at the Yellow River Delta region in autumn. The method comprises the following steps of land selection and land preparation, selection and treatment of cutting slips, placement of seedling raising paper cylinders, cutting of thecutting slips, earthing, watering, secondary earthing and film covering. The method has the advantages that (1) Chinese silvergrass propagation can be carried out at the Yellow River Delta region inautumn; (2) the labor can be reduced, the land is saved, and the energy sources are saved; (3) the Chinese silvergrass propagation coefficient is greatly increased, the large-scale and standardized propagation is performed, and a propagation method is provided for the large-scale and standardized production of Miscanthus in the Yellow River Delta saline-alkali area.

Description

technical field [0001] The invention belongs to the field of plant propagation, and in particular relates to a stem segment cutting propagation method of miscanthus in the Yellow River Delta region in autumn. Background technique [0002] Miscanthus is a perennial C4 tall herbaceous plant of Poaceae. It has the characteristics of high biomass yield, excellent biomass yield, low planting cost, and strong adaptability. It is considered to be a biomass energy plant with great development potential. Its young The leaves can be used as livestock feed, and the plants have the functions of greening and beautifying and improving saline-alkali soil, and can have a good ecological effect on the saline-alkali marginal land in the Yellow River Delta region. [0003] The following problems exist in the propagation of Miscanthus in autumn in the Yellow River Delta region: (1) Due to its biological properties, the growth temperature of Miscanthus must be above 10°C. The autumn temperature...

Problems solved by technology

(2) Miscanthus has a well-developed root system, and the root system is entangled in the traditional field seedling cultivation method. It is not only labor-intensive to transplant and plant, but also there is a phenomenon of slow seedlings after transplanting, and the growth period after transplanting is long.

(3) Miscanthus multiplication should be propagated by underground stem divisions, which has a low reproduction coefficient and high work intensity
