Problems solved by technology

With the deepening of the research, in subsequent further experiments, it was found that in an alkaline environment, the osmotic pressure of domestic waste composting is relatively high, and various salts, heavy metals, minerals, and even organic matter in the composting matrix are relatively high. When domestic waste compost is used as the main material, when preparing turf cultivation substrate or applying it to turf plants as a base fertilizer for turf plants, it is easy to cause the turf plants to absorb water, which makes the turf plants grow slowly under high osmotic pressure. As a result, the plant height, freshness and Indexes such as weight and chlorophyll content decreased, which affected the ornamental quality and normal growth of lawn plants

Embodiment 1

[0042] (1) Put 500g of garbage compost with a particle size of 1.8mm in a large funnel covered with filter paper in advance, and use 1000ml of HCl+CaCl with a pH value of 6 2The solution was rinsed, and each treatment was repeated twice; until the solution in each funnel no longer leaked downward. Finally rinse once with clear water, and the compost after rinsing is used as the substrate for cultivating lawn plants.

[0043] (2) Take a flowerpot with air holes at the bottom, put 4kg of substrate after washing into it, sow 25g of ryegrass plants on the surface of the flowerpot, grow under natural light, and the indoor temperature and relative humidity are 21°C and 39% respectively Sprinkle appropriate amount of water every day to keep the water holding capacity of the substrate at 60-65%, measure the plant height every 20d, measure the plant height once every 20d after germination, and measure the total chlorophyll content after the last mowing to be 7.95 (mg· g-1) for the con...

Embodiment 2

[0045] Source of raw materials: Same as above.

[0046] (1) Put 1500g of garbage compost with a particle size of 1.2mm in a large funnel covered with filter paper in advance, rinse with 3000ml of HCl+CaCl2 solution with a pH value of 6; finally rinse once with water, and repeat twice for each treatment ; until the solution in each funnel no longer leaks downwards. The compost after rinsing is used as the substrate for cultivating lawn plants.

[0047] (2) Get a flowerpot with air holes at the bottom, put 4kg of matrix after washing into it, sow 30g of tall fescue on the surface of the flowerpot, grow under natural light, and the indoor temperature and relative humidity are 21°C and 39% respectively Sprinkle appropriate amount of water every day to keep the water holding capacity of the substrate at 60-65%, measure the plant height every 20d, measure the plant height once every 20d after germination, and measure the total chlorophyll content after the last mowing to be 7.85 (m...

Embodiment 3

[0049] (1) Put 500g of garbage compost with a particle size of 3mm in a large funnel covered with filter paper in advance, and use 1500ml of HCl+CaCl with a pH value of 6 2 The solution was rinsed; each treatment was repeated twice; finally, the solution was rinsed once with water until the solution in each funnel no longer leaked downward. The compost after rinsing is used as the substrate for cultivating lawn plants.

[0050] (2) Get the flower pot that air hole is arranged at the bottom, pack into matrix 5kg, sow tall fescue plant 35g on the surface of flower pot, grow under natural light, indoor temperature and relative humidity are respectively 26 ℃ and 39%, every day Spray an appropriate amount of water to keep the water holding capacity of the substrate at 65%, measure the plant height every 20 days, measure the plant height every 20 days after germination, and measure the total chlorophyll content after the last cutting to be 8.12 (mg·g-1) The control was 7.23 (mg·g-1...

Abstract

The invention relates to a method adopting a leacheate to reduce the osmotic pressure of garbage composts with different particle diameters, comprising: repeatedly leaching the treated garbage composts with particle diameters of 0.8 to 1.6mm or 3mm< particle diameter of compost>1.6mm by an HCl+CaCl2 solution with a pH value of 4 to 6.5 for one to two times, then leaching the composts by clear water, thereby reducing the osmotic pressure of the garbage composts. The leached composts can serve as a matrix for breeding lawn plants, and experiments verify that: the leaching method of the invention can effectively reduce the osmotic pressure of domestic garbage composts, and can also enhance the growing ability of the lawn plants on the garbage compost matrix, and the technique provides data support for the field production in the future.

Description

technical field [0001] The invention belongs to the technical field of urban environmental protection and relates to a method for reducing the osmotic pressure of garbage composting with different particle sizes by using eluent. Background technique [0002] At present, there have been a large number of relevant research reports on the establishment of domestic waste composting lawns. For example, adding domestic waste compost to the soil can significantly promote the growth of stems and roots of ryegrass, increase the biomass, improve the color and uniformity of leaves, and improve the density and quality of lawns, etc. In addition, studies have shown that the turf cultivation substrate was prepared with domestic waste compost as the main material, and it proved that the compost preparation substrate has good performance in the plant density, plant height, root growth, green period and greenness of turf plants. . But the household waste compost used at present all is to a...
