Embodiment Construction
[0014] The present invention distributes points in the Picardia area of northern France to carry out a series of experimental research on high-yield cultivation techniques. Through the research on Miscanthus biological characteristics and high-yield cultivation technology, its high-yield cultivation method is realized as follows:
[0015] Do a good job of soil preparation and ridge work before winter. The distance between ridges is 480 cm, and the ridges are straight. Planting began in late March, with a planting density of 20,000 plants / ha. The furrows were plowed with plows on ridges. The distance between the furrows was 80 cm, and the depth of the furrows was 20 cm. The massive stems were planted at a distance of 60 cm, and the soil was restored to preserve moisture. .
[0016] After the tuberous stem survives and emerges, loosen the soil and weed, so that the soil is loose and free of weeds. A combination of artificial weeding and chemical weeding is adopted, and chemi...

This invention discloses a method for culturing Chinese silvergrass with high yield, relating to the technical field of the plant cultivation. The method comprises the steps of: preparing soil before winter, removing weed on the soil to be used for planting the Chinese silvergrass, ploughing up, making ridge and preserving soil moisture in time; planting at proper time from March to April with planting density of 2 plants per sq.m.; culturing during the same year, loosing soil and hoeing weed in time after blocky stem growing with sprouts; preventing cold and frozen weather, spraying ethephonto promote dormancy during November and December, at the time, using hay, or / and polyethylene film, or / and a ridging method to cover to ensure hibernation; fertilizing and irrigating until the secondyear; and late harvesting at proper time. The method for culturing Chinese silvergrass with high production is initiative, and has the remarkable characteristics that the method is suitable for planting blocky stems or other organ and tissue culturing materials, can achieve high yield in large area, has the average yield of the Chinese silvergrass of one ton per hectare in the first year, 11.3 tons in the second year and 20.7 tons in the third year; and can be generalized widely.
Description
technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a biomass energy plant Miscanthus ( Miscanthus x giganteus ) high-yield breeding method. Background technique [0002] Miscanthus ( Miscanthus x giganteus ) original species are produced in various places in the north and south of China. It is a perennial herbaceous plant of Gramineae and belongs to the parent plant of sugarcane. It can reach a height of 4 meters and grow in clusters. Most of the leaves are basal, flat and up to 1 meter long. Terminal racemes, scattered room-like spikes around the main axis, clusters of filamentous hairs on spikelets, red inflorescences formed in autumn. Hi sunny and moist sandy loam. Miscanthus can adapt to various types of soil and has good drought resistance. It only consumes 400 mm of water to produce 15 tons of dry matter per hectare. Miscanthus has high photosynthetic efficiency, and the dry matter yield is as high as 30 tons...
