Embodiment 1

[0046] (1) First remove all kinds of wood, plastic, glass, metal and other sundries, then dry at 105°C to constant weight, and sieve compost with a particle size of 1700nm. Compost with a particle size of 1700nm was crushed at 24000 rpm for 3 minutes, 6 minutes, and 9 minutes to prepare compost with different particle sizes. The particle sizes of the obtained compost after treatment are 300nm, 240nm and 100nm, respectively. For the convenience of expression in the text, in order of compost particle size from large to small, the above three particle size composts are referred to as: compost 4, compost 5 and compost 6. , 1700nm particle size compost as a control (CK). Perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea L.) seeds with plump and uniform grains were selected as experimental materials. Among them, the organic matter content in the compost is 22.00%, and the bulk density is 0.79g.cm -3 , pH value 7.62, porosity 67.98%, saturated water conten...

Embodiment 2

[0051] Others are the same as example 1. The 300nm, 240nm and 100nm particle size composts were rinsed with distilled water at a weight fraction ratio of 15:1, each treatment was repeated 3 times, and the rinse solution collected after the rinse was used as a spray solution;

[0052] (3) adopt diameter 7cm, high 10cm plastic basin, be every basin 150g soil (loam soil) by lawn substrate, sow lawn plant (ryegrass or tall fescue) 0.5g / pot, at the initial stage of sowing, every basin fully waters, To ensure the smooth germination of seeds and the initial growth of seedlings, after two weeks, spray compost 6 according to the stress level of 55% of the field water capacity, and then weigh and spray compost 6 every one to two days to maintain the stress range; the experiment lasted 60 days , and then cut off the lawn plants at the same root, and measure each index. The content of ryegrass stems and leaves was the highest when spraying compost 6, which was 24.2% higher than that of t...

Embodiment 3

[0055] Others are the same as example 1. The 300nm, 240nm and 100nm particle size composts were rinsed with distilled water at a weight fraction ratio of 15:1, each treatment was repeated 3 times, and the rinse solution collected after the rinse was used as a spray solution;

[0056] (3) adopt diameter 7cm, the plastic pot of high 10cm, be every pot 150g soil (loam) by lawn substrate, sow tall fescue plant 0.5g / pot, at the early stage of sowing, every pot fully waters, guarantees that seed can germinate smoothly and The seedlings grow at the initial stage, and after two weeks, spray compost 5 according to the stress level of 55% of the field water capacity, and then weigh and spray compost 5 every one to two days to maintain the stress range; the experiment lasts for 60 days, and then the tall fescue roots Cut out and measure. When compost 5 was sprayed, tall fescue's absorption of a large number of elements could be most promoted, and the content of calcium, potassium, and ...

Abstract

The invention relates to a method for promoting the mineral nutrition absorption of a lawn by using the extract of fine refuse composts. The method comprises the following steps of: pre-processing refuse composts; crushing the compost having the grain size of 1,700 nm at a rotating speed of 24,000 rpm to prepare refuse fine fertilizers having the different grain sizes of 300nm, 240nm and 100nm; showering the refuse composts having the different grain sizes by using distilled water in a weight part ratio of 15: 1, and collecting leacheate as foliage spraying liquid; spraying the leacheate into a lawn base material which contains 150 grams of soil and 0.5 gram of lawn plant in each pot to ensure the smooth sprouting of seeds and the primary growth of seedlings, spraying the leacheate according to a stressed degree of 55 to 65 percent based on the water-holding capacity of a field after two weeks, and weighing and spraying every one or two days to keep the stressed degree; and continuously performing the experiment for 60 days and then detecting all indexes. Experiment results show that the foliage spraying of the extract of the composts having different grain sizes is favorable for the mineral element absorption of the lawn plants.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to the reasonable use of composting of municipal domestic garbage. More specifically, it is a method for improving the mineral nutrient absorption of lawn plants by adopting fine garbage compost extract. Background technique [0002] Lawns play an important role in urban greening, environmental protection and ecological balance. The planting and maintenance of turfgrass requires a lot of water; the large demand for irrigation water makes the maintenance cost of turfgrass extremely high. develop. [0003] In general, the increase of plant mineral nutrition is beneficial to the water saving of plants. Therefore, the method of improving plant mineral nutrition has important practical significance for water saving. The traditional water-saving methods of lawns are through the selection of drought-resistant varieties, the economical irrigation amount of lawns and the sel...
