A kind of method of propagation of miscanthus in autumn in the Yellow River Delta

Abstract

The invention relates to the field of plant propagation, and mainly provides a method for large-scale vegetative propagation of Miscanthus in the field by cutting stems in autumn in the Yellow River Delta region. The method comprises the following steps: selecting and preparing the soil, selecting and processing cuttings, placing seedling raising paper tubes, cutting cuttings, covering with soil, watering, covering with soil for a second time, and covering with film. The characteristics of the present invention are: (1) Miscanthus can be propagated in the Yellow River Delta region in autumn; (2) It can reduce labor, save land, and save energy; (3) It can greatly improve the reproduction coefficient of Miscanthus, and carry out large-scale and standardized propagation. It provides a breeding method for the large-scale and standardized production of Miscanthus in the saline-alkali area of ​​the Yellow River Delta.

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
