The invention provides a method for rapidly propagating and growing
pennisetum hydridum on municipal
sludge. According to the method disclosed by the invention, stems of naturally grown
pennisetum hydridum are horizontally pressed on
sludge, and tillering nodes of the
pennisetum hydridum are covered with
sludge; and after the tillering nodes root and sprout, the contact between the stems and a parent is
cut off. According to the invention, tolerance of the pennisetum hydridum to harmful substances in the sludge is enhanced, the pennisetum hydridum can be directly and rapidly grown on the toxicsludge, the
survival rate of the pennisetum hydridum in the sludge is greatly improved, the
survival rate of 100% can be realized, and the
reproduction and
growth speed of the pennisetum hydridum canbe accelerated. Meanwhile, efficiency of
drying sludge by the pennisetum hydridum is remarkably improved, and the
biomass of the pennisetum hydridum is greatly improved. Seedlings do not need to
breed in advance, so that cost is low;
plant treatment does not consume energy; the sludge is decomposed,
nutrient substances in the sludge are less lost, and the treated sludge can be continuously used as a
fertilizer, or can be incinerated and buried, so that selectivity is high. The method is easy to apply and popularize and has a good prospect.
