Problems solved by technology

This patent has the following disadvantages: (1) The material is first dried to a moisture content of ≤10%. When mass-produced, a large amount of electric energy will be consumed and the production cost will be increased.
Regardless of the use of electric energy or coal pyrolysis, it is a kind of energy consumption, which will eventually directly or indirectly cause harm to the environment
(3) After the second pyrolysis, it needs to be soaked in water for desalination. The overall steps are somewhat cumbersome, which will increase manpower and material resources. If it is used as a vegetable seedling substrate, the cost will be very high.

Embodiment 1

[0023] Embodiment 1: the preparation of vegetable seedling raising substrate

[0024] First, the landscaping waste is crushed into particles with an average particle size of 1 to 5 mm by a pulverizer, and the basic physical and chemical properties of the landscaping waste and two auxiliary materials, tea dregs and pig manure, such as pH, carbon-nitrogen mass ratio, and water content are tested and analyzed respectively. Properties, mix landscaping waste (20kg), tea leaves (10kg), and pig manure (10kg) evenly, adjust the moisture content to 60%, and the carbon-to-nitrogen mass ratio to be 30, and carry out forced-air aerobic composting;

[0025] Carry out aerobic composting in an aerobic composting reactor with a heap size of 80L (insulation measures are added in winter), forced interval ventilation and oxygen supply, and a ventilation rate of 250L / H. The ventilation mode is 10 minutes on, 50 minutes off, and lasts for 30 days , and in the first 15 days of composting, turn the ...

Embodiment 2

[0027] Embodiment 2: the cultivation comparative test of different seedling-raising substrates

[0028] The vegetable seedling raising substrate, peat, and garden soil (ground through a 2mm sieve) prepared in Example 1 are combined in pairs, and the two materials are mixed evenly in a volume ratio of 1:1 in each combination to form Example 1. Substrate+peat, embodiment 1 substrate+garden soil, three kinds of mixed substrates of peat+garden soil, and embodiment 1 substrate, peat charcoal, garden soil three kinds of simple substrates, a total of 6 kinds of cultivation substrates carry out comparative test of green vegetable seedling cultivation (Table 1) .

[0029]Put the 6 kinds of substrates in plastic seedling trays with 50 holes respectively, and put two cabbage seeds in each hole, water all the cultivation substrates thoroughly and cover them for heat preservation. Observe the growth status of the cabbage seeds every morning. figure 1 Show, through 15 days' seedling raisi...

Abstract

A provided vegetable seedling-growing matrix is prepared from garden greening waste, tea residue and pig manure. A preparation method of the vegetable seedling-growing matrix comprises: firstly crushing garden greening waste; then uniformly mixing crushed garden greening waste, tea residue and pig manure according to a weight ratio of 4-6:2:2, adjusting the water content to be 55%-65% and the carbon-nitrogen mass ratio of 25-30, and performing forced ventilation for aerobic composting; and obtaining the vegetable seedling-growing matrix after the composting process is finished. The vegetable seedling-growing matrix has the advantages of being low in cost, wide in source, less in compositions kinds, easily available in material, stable in properties, environment-friendly, efficient, easy to survive and the like.

Description

(1) Technical field [0001] The invention relates to a vegetable seedling-raising substrate and a preparation method thereof, in particular to a soilless vegetable seedling-raising substrate material mainly prepared by composting landscaping waste. (2) Background technology [0002] Industrialized seedling cultivation is an important part of modern agriculture. With the increasing population of human society, the traditional vegetable planting methods are becoming more and more incapable. People pay more attention to the research on finding rapid seedling substrates. At present, the most used seedling substrate materials are Peat, rock wool, vermiculite, perlite, gravel, ceramsite, etc. The ideal cultivation substrate recognized in the world is peat and rock wool. But peat and rock wool are non-renewable resources. Extensive mining not only destroys the ecological environment of the soil, but also depletes natural resources such as peat. Therefore, the development of a new...
