Problems solved by technology

However, spring is the season with the largest demand for turf, and lawn companies often have to choose to plant turf in advance to meet the needs of spring, which not only increases the cost, but also takes up resources
At the same time, production cannot be carried out throughout the winter, causing time to be idle

Embodiment 1

[0083] (1) The compost comes from Tianjin Xiaodian Garbage Compost Treatment Plant, and it is dried to constant weight after coarse screening. Weigh 400g of the dried compost after coarse sieve, put it into a large funnel, measure 400ml tap water and filter, and collect the filtrate. Repeatedly measure twice 400ml of tap water to continue to filter the compost, and collect the filtrate of each time. Mix the filtrate collected three times and store in the refrigerator. Put the compost dregs after three filtrations into an oven at 105°C and bake to constant weight.

[0084] (2) Take ryegrass seeds with full and uniform grains, and sown them in a petri dish with two layers of filter paper and 50g of compost slag after treatment, 1g per dish, and place the seeded petri dish in the laboratory For germination, water once a day in the morning and evening. Change the position of each petri dish frequently to ensure consistent light. During the cultivation period, the average temperat...

Embodiment 2

[0088] The compost comes from Tianjin Xiaodian Garbage Compost Treatment Plant, which is dried to constant weight after coarse screening. Weigh 400g of the dried compost after coarse sieve, put it into a large funnel, measure 400ml tap water and filter, and collect the filtrate. Repeatedly measure twice 400ml of tap water to continue to filter the compost, and collect the filtrate of each time. Mix the filtrate collected three times and store in the refrigerator. Put the compost dregs after three filtrations into an oven at 105°C and bake to constant weight. The planting time is November 18, 2008.

[0089] The seed germination time was November 22, 2008. Starting from the tenth day after the seed germination, 5ml of compost leaching solution was poured into each filter paper culture dish of ryegrass seedlings every day. 40 days after germination, the seeds are moved to a light incubator, the initial set temperature is 12℃, and the temperature is lowered sequentially every day....

Abstract

The invention discloses a method for improving winter resistance of turf by adopting household garbage compost offscourings. The ryegrass seedlings cultivated by compost and cold-hardened in cold environment with gradually decreased temperature have no obvious difference from the seedlings in the control group in indexes such as protective enzyme, proline and conductivity, but are slightly shorter. The aboveground biomass of the cold-hardened ryegrass seedlings cultivated by compost offscourings is reduced by 26.74% compared with that of the seedlings in the control group and is reduced by 23.21% compared with that of the seedlings with relatively poorer matix nutrition in the filter paper group. The final technical effect shows that the cold-hardened turf can fully resist winter in the winter environment of not less than 10 DEG C below zero in the outdoor balcony without being provided with a heating facility, and the aim of storing the turf in winter and producing all year around isachieved.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection and relates to a method for urban lawn plants to withstand severe cold. More specifically, it is a method of using municipal solid waste compost dregs to improve the cold and wintering resistance of turf. Background technique [0002] Urban lawn is an important part of the urban greening system. Urban lawns not only play an irreplaceable role in greening, beautifying, sports and leisure venues, but also have great significance in maintaining the balance of the urban ecological environment and regulating the construction of ecological functions. With the continuous improvement of people's living standards and the continuous improvement of urban infrastructure construction, the requirements for urban lawns are getting higher and higher. The quantity and quality of lawns are important indicators of the level of urban greening. The amount of green area per capita in a city has become an...
