Embodiment 1

[0028] The embodiment of the present invention is a pot experiment carried out in an outdoor field. The sludge is taken from a sludge composting plant in Dongguan City, Guangdong Province. The sludge has been piled up for half a year and has become anaerobic. The sludge is black in color and has a foul smell. More toxic to plants.

[0029] (1) Put the sludge into a black nutrition bag with a specification of 28mm×30mm, each nutrition bag contains 6kg of sludge, and do the following three treatments (three repetitions for each treatment).

[0030] Treatment 1: Blank treatment (CK), no emperor bamboo grass planted;

[0031] Treatment 2: Seedling cultivation and transplanting treatment, plant and cultivate one-month-old Huangzhucao seedlings in a nutrient bag of about 0.25kg substrate. The seedlings must have two tiller nodes, and each nutrition bag is planted with two well-growing Huangzhucao. , transplanted with substrate;

[0032] Treatment 3: Siamese branch pressing improve...

Embodiment 2

[0047] In order to further study the necessity of conjoined bamboo-grass treatment by conjoined pressing, a further study of this embodiment was carried out.

[0048] Cut off the well-growing royal bamboo grass with tiller joints at 10 to 20 cm above the ground, place it horizontally on a nutrition bag containing 6 kg of sludge, and cover the tiller joints of the royal bamboo grass with sludge, set up three parallel, Observe whether the emperor bamboo grass can survive. At the same time, set a blank treatment, that is, use nutrient bags to pack 6kg of sludge, do not plant emperor bamboo grass, and set up three parallels to compare the effect of this treatment on sludge drying.

[0049] The results of the experiment found that if the roebusta was cut off and a whole plant was placed horizontally and planted on the sludge, the roebush could not survive, and all tiller nodes did not take root and germinate. In the third week of the experiment, the roebush completely withered, and...

Abstract

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.

Description

technical field [0001] The invention belongs to the intersecting field of waste treatment and utilization and plant cultivation technology, and particularly relates to a method for rapidly propagating and growing royal bamboo grass on municipal sludge. Background technique [0002] There are many municipal sewage treatment plants in our country, the sludge output is large, and the proportion of safe utilization is low. Moreover, in general, the content of fine sand is large and the content of organic matter is low, which leads to low calorific value of sludge, which is not conducive to incineration treatment. Adopt current heat drying method, cost is high. Therefore, it is very necessary to adopt an environment-friendly ecological method to dry and stabilize municipal sludge. [0003] Fresh sludge from urban sewage treatment plants generally contains about 80% water, which is phytotoxic and affects seed germination and plant growth. The team of inventors found that direct...
