Embodiment 1

[0082] (1) Preparation of compost eluent:

[0083] Weigh 200g of garbage compost, add 400ml of deionized water, stir well, soak for 24 hours, filter, the resulting solution is the compost eluate, and finally put the eluent in a brown bottle, and refrigerate at 4°C for later use;

[0084] (2) Lawn plant cultivation:

[0085] The collected plants were potted, the height of the soil substrate was 10cm, and 25 plants were evenly sown in each pot; they were mowed after one week, and the experimental treatment was carried out when the plants grew into three-leaf and one-heart stage: the treatment group was given compost eluent supply , the control group was not supplied with compost eluent; water was supplied uniformly and quantitatively every day to keep the lawn plant culture medium in a good water condition, and the positions of each culture dish were often changed to ensure consistent light. The test was carried out on a greenhouse plant culture platform at a temperature of 26°...

Embodiment 2

[0089] (1) Garbage compost comes from Tianjin Xiaodian Garbage Composting Treatment Plant, and passes through a 2mm sieve after drying. In this experiment, perennial ryegrass (Lolium ryegrass), a common lawn plant in northern my country Lolium perenne L.), obtained from Turf Plants of Tianjin Normal University. The experimental soil was taken from Tianjin Normal University, which is the soil below 30cm of the surface (to avoid too many weed seeds).

[0090] (2) Preparation of compost eluent

[0091] Weigh 400g of garbage compost, add 1200ml of deionized water, stir well and soak for 24 hours. Filter with qualitative filter paper, and the resulting solution is the compost eluent. Finally, put the eluent in a brown bottle and refrigerate at 4°C for later use.

[0092] (3) The tested grass species is perennial cool-season ryegrass ( Lolium perenne L.) was obtained from the lawn plants of Tianjin Normal University, and the collected plants were potted in plastic cups (the hei...

Embodiment 3

[0096] (1) Preparation of compost eluent:

[0097] Weigh the garbage compost, add deionized water, stir well, soak for 48 h, filter, the obtained solution is the compost eluent, and finally put the eluent in a brown bottle, and refrigerate at 4°C for later use; the garbage compost and deionized The weight to volume ratio of ionized water is 1:4.

[0098] (2) Lawn plant cultivation:

[0099] Plant the collected plants in pots with a soil substrate height of 15 cm, and sow 30 plants evenly in each pot; mow them after a week, and provide composting rinse solution when the plants grow into three-leaf one-heart stage, and uniformly ration water every day. In order to keep the lawn plant culture medium in a good water condition, the positions of the culture dishes were often changed to ensure consistent light. The test was carried out on the greenhouse plant culture platform, the temperature was 26°C, the relative humidity was 70%, and the light penetrated into the room. Natural l...

Abstract

The invention discloses a method for improving winter resistance of turf in Tianjin by adopting municipal garbage compost filtrate. The method mainly comprises the following steps: (1) preparing compost eluent, (2) cultivating lawn plants, and (3) carrying out cold hardening and sampling. The final technical effect shows that cold-hardened turf can fully resist winter in the winter environment ofnot less than 10 DEG C below zero in the outdoor balcony without being provided with a heating facility in the house of Tianjin, and the aim of storing the turf in winter is achieved. Compared with the peripheral turfgrass, the ryegrass seedlings turned green in spring next year has obvious advantages, which means that the garbage compost filtrate plays an important role in lawn plant growing andwinter resisting and plays a guiding role in applying the garbage compost filtrate to the growth of the turf in winter. The technology lays a foundation for the production of the turf all year around.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a method for improving the cold resistance and overwintering performance of turf by adopting the composting filtrate of municipal domestic garbage. Background technique [0002] In recent years, perennial ryegrass ( Lolium perenne L.) is gradually accepted by everyone because of its good cold resistance, long green period, and resistance to extensive management, and has gradually been popularized and applied. However, in Tianjin, the winter climate is relatively cold, dry and snowy, and the extreme minimum temperature is about minus 7~9°C. In spring, it is windy and rainy, and many lawns show yellowing in winter and are in a dormant state, which greatly shortens the green color of ryegrass lawns. Expect. In some poorly managed lawns, there are even two seasons of yellowing in summer and winter, making the lawn of "four seasons green" into "two seasons of yellow". ...
