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 Composting Plant, which is coarsely screened and dried to constant weight for later use. Weigh 400g of compost dried after coarse sieving, put it into a large funnel, measure 400ml of tap water to filter, and collect the filtrate. Repeatedly measure twice 400ml of tap water to continue filtering the compost, and collect the filtrate each time. The filtrates collected three times were mixed and stored in the refrigerator. The compost slag after filtering three times was put into an oven at 105°C and dried to constant weight.

[0084] (2) Take ryegrass seeds with full and uniform grains, and sow them respectively in petri dishes covered with two layers of filter paper and 50g of treated compost dregs, 1g per dish, and place the petri dishes with seeds in the laboratory For germination, water once a day in the morning and evening, and change the position of each petri dish frequently to ensure consistent light. During t...

Embodiment 2

[0088] The compost comes from Xiaodian Garbage Composting Treatment Plant in Tianjin, and it is coarsely screened and dried to constant weight for later use. Weigh 400g of compost dried after coarse sieving, put it into a large funnel, measure 400ml of tap water to filter, and collect the filtrate. Repeatedly measure twice 400ml of tap water to continue filtering the compost, and collect the filtrate each time. The filtrates collected three times were mixed and stored in the refrigerator. The compost slag after filtering three times was put into an oven at 105°C and dried to constant weight. The planting time is November 18, 2008.

[0089] The seed germination time was November 22, 2008. Since the tenth day after the seed germination, 5ml of compost eluent was poured into the culture dish in which the ryegrass seedlings were cultivated on each filter paper every day. 40 days after the seeds germinated, they were moved into the light incubator. The initial set temperature wa...

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 is achieved.

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 for improving the cold resistance and overwintering performance of turf by adopting municipal solid waste composting dregs. Background technique [0002] Urban lawn is an important part of 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 and green spaces are getting higher and higher. The quantity and quality of lawn is an important symbol of urban greening level. The amount of green area p...
