Problems solved by technology

Rock wool is mainly imported, fine vermiculite, peat and perlite are unevenly distributed in China and resources are limited, carbonized rice husks are small and processing is relatively troublesome, and local resources such as sawdust, cottonseed husks and fine sand are insufficient and there are many ways to use them , the cost of organic fertilizer is high
Since the source of materials is limited by region and cost, from the perspective of long-term production development, these substrates do not meet the needs of local large-scale vegetable seedling cultivation. Therefore, it is necessary to develop a substrate suitable for local large-scale vegetable seedling cultivation
[0003] Chestnut shells and peanut shells are plant shells, which are generally difficult to use and are usually disposed of by incineration, but incineration will produce a lot of smoke and pollute the air
The biggest problem in chicken farms and pig farms is the disposal of chicken manure and pig manure. Usually, chestnut shells and peanut shells are discarded in a certain area, which not only wastes resources, but also causes the unpleasant smell of chicken manure and pig manure Cause air pollution, but also easy to breed bacteria, flies, etc.
If the slag ash discarded after power generation in thermal power plants is not utilized, it will not only occupy land resources for storage, but also cause serious environmental pollution

Abstract

The invention discloses a vegetable plug seedling composite substrate and a preparation method thereof. The substrate comprises the following components in percentage by volume: 60-80 percent of chestnut shell and/or peanut shell composting product, 10-20 percent of thoroughly decomposed chicken manure and/or pig manure and 10-30 percent of furnace slag ash and/or perlite. The preparation method comprises the following steps: treating chestnut shell and/or peanut shell and chicken manure and/or pig manure by piling and covering a film for decomposing; smashing waste furnace ash slag and sieving; fully and uniformly mixing the obtained chestnut shell and/or peanut shell composting product, the thoroughly decomposed chicken manure and/or pig manure and the furnace slag ash and/or perlite to obtain the composite substrate. In the composite substrate, the waste chestnut shell and/or peanut shell, chicken manure and/or pig manure and furnace slag ash and/or perlite are taken as raw materials which are readily available, so that waste is turned into wealth, resources are saved, and the local environmental pollution is lowered; more importantly, the composite substrate is lower in cost than the conventional substrate but higher in nutrition than the conventional composite substrate, and has a good seedling effect.

Description

technical field [0001] The invention relates to a vegetable plug seedling-raising composite substrate and a preparation method thereof, in particular to a plug-tray seedling-raising composite substrate suitable for solanaceous plants, such as eggplant, pepper, tomato and potato, and belongs to the technical field of vegetable plug seedling-raising substrates. Background technique [0002] At present, the seedling substrates of Solanaceae and melon vegetables mainly include rock wool, fine vermiculite, peat (peat), perlite, sawdust, carbonized rice husk, cotton seed husk, fine sand and organic fertilizer, etc. It can be used singly, or several of them can be used in combination. Rock wool is mainly imported, fine vermiculite, peat and perlite are unevenly distributed in China and resources are limited, carbonized rice husks are small and processing is relatively troublesome, and local resources such as sawdust, cottonseed husks and fine sand are insufficient and there are man...
