Problems solved by technology

However, many construction units do not pay much attention to this issue due to cost considerations. The fundamental reasons are: (1) In places with high slopes or water shortages, watering and maintenance are more difficult. Due to the high slope, it is difficult for the pump to pump to the required level Height; (2) The cost of pulling water from a long distance is very hi...

Embodiment

[0045] After spraying greening on a high-speed slope in the north, the maintenance measures adopted are as follows (combined with the above specific implementation methods):

[0046] 1. Watering: Before the emergence of plant seeds, water once a day in the morning and evening (7 am and 5:30 pm) (the water pressure during watering is 1.8 atmospheres). After the plant seeds emerge, the frequency of watering can be gradually reduced. When the grass seedlings grow to 5-6cm or 2-3 leaves, remove the non-woven fabric; the slope plants will be transferred to conventional management after they become lawns.

[0047] 2. Fertilization: when the slope lawn and other plants grow to 4~5 leaves, top-dress with high-quality commercially available compound fertilizer, 10g / m each time 2 about.

[0048] 3. Prevention and control of diseases and insect pests: When young plants such as lawns are prone to brown spot and pythium wilt, especially in high-temperature seasons, broad-spectrum fungici...

Abstract

The invention relates to a slope maintenance method. The slope maintenance method comprises the following steps of (1) fixing non-woven fabrics on a slope sown with seeds, and performing watering maintenance on the slope; wetting soil with the depth of 12-18cm during maintenance for the first time; keeping a surface layer, with the depth of 6-7cm, of the soil moist after 18-20 days; and removing the non-woven fabrics when the heights of vegetations on the surface of the slope are 5-10cm, watering the vegetations three times every week, wetting the soil with the depth of 1-2cm every time, and guaranteeing that the total watering time is not less than 30 days; (2) performing topdressing according to N:P:K=1-2.5:0.5-1.5:15-20g/m(2) during seedling stage of the vegetations on the slope, and performing topdressing according to N:P:K=8-12:6-8:4-6g/m(2) after seedling; and (3) spraying broad-spectrum agents during seedling stage of the vegetations on the slope. By using the slope maintenance method, field experiences are combined with experiments; a feasible solution is provided for solving the problem that later maintenance is difficult in a slope spraying technology; and the slope maintenance method facilitates greening of the domestic slope engineering.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a method for maintaining slopes. Background technique [0002] As the country strengthens the management of geological disasters and dangerous slopes, human beings’ requirements for the living environment continue to increase. Some slopes with potential safety hazards will be stabilized after treatment, but the vegetation will be severely damaged. , The soil will be exposed in large quantities, forming strong visual pollution, which is not in harmony with human requirements for the environment. Now spraying greening technology has become a routine means of slope ecological restoration. Compared with the previous greening scheme, the soil and vegetation cannot be fixed on the bare rock, and the vegetation planted in the soil layer after slope cutting is not easy to survive due to the damage of nutrition and environment. Therefore, spraying slope protection technology is...
