Problems solved by technology

However, the most important thing in the soilless cultivation of lawns is that the natural soil needs to be replaced by the substrate in the cultivation process, which consumes fertilizer and water, and the entire production process of the lawn requires that the cultivation substrate has good structure, physical and chemical properties and supporting fertilizer and water management measures. Therefore, this method still has the disadvantage of high production cost at present.

Embodiment 1

[0029] A method for substrate-free cultivation of warm-season lawns based on artificial floating beds, the specific steps are as follows:

[0030] (1) Select livestock and poultry wastewater from aquaculture without chemical pollution and ferment it. Since the background level of nutrients such as nitrogen and phosphorus in the water body is very high, it is diluted 10 times and stored in plastic turnover box 3 (inner size: 560×460× 355 (mm)), the diluted water body total nitrogen (TN) concentration is 234.9mg / L, total phosphorus (TP) concentration is 21.6mg / L, COD Cr The concentration is 584.6mg / L, and the depth of the water body in the turnover box is not less than 300mm, and then placed in a greenhouse with open surroundings, so as to facilitate normal ventilation and cooling in summer high temperature season;

[0031] (2) Select seashore paspalum (germplasm number P055) which has high value for turf use, good flooding resistance, and is suitable for growing on the surface ...

Embodiment 2

[0037] A method for substrate-free cultivation of warm-season lawns based on artificial floating beds, the specific steps are as follows:

[0038] (1) Select livestock and poultry wastewater from aquaculture without chemical pollution and ferment it, dilute it by 10 times and put it in the plastic turnover box 3 (inner size: 560×460×355 (mm)), the diluted water body TN, TP and COD Cr Concentrations are 234.9mg / L, 21.6mg / L and 584.6mg / L respectively, the depth of the water body in the turnover box is not less than 300mm, and then placed in the open greenhouse around;

[0039] (2) Select Pseudomonas japonica (germplasm number E039) which has high value for turf use, good flooding resistance, and is suitable for growing on the surface of eutrophic water bodies as the grass species for floating bed substrate-free cultivation;

[0040] (3) Make a "day"-shaped frame 1 with a PVC pipe with a diameter d of 40mm, cover the frame with a fishing net carrier 2 with an aperture of ￠15mm, an...

Abstract

The invention provides a substrate-free cultivation method of a warm-season lawn based on an artificial floating bed, and belongs to the technical field of landscaping and lawn cultivation. The methodincludes the steps: spreading grass seed stem sections of the warm-season lawn on the artificial floating bed, and culturing the grass seed stem sections in water; covering the artificial floating bed with carrier with the hole diameter of 10-20mm. The grass seed stem sections of the warm-season lawn include seashore paspalum and / or centipede grass stem sections. By the method, substrate-free cultivation of the lawn is achieved, and the grass seed stem sections can grow to form the lawn without routine management such as fertilization and irrigation.

Description

technical field [0001] The invention belongs to the technical field of landscaping and lawn cultivation and production, and in particular relates to a substrate-free cultivation method for a warm-season lawn based on an artificial floating bed. Background technique [0002] Lawns play an important role in urban greening, protecting and improving the environment, and maintaining ecological balance. At present, most of the lawn cultivation is the traditional soil cultivation mode. In the production process, there are problems such as occupying a large amount of cultivated land, destroying the surface soil structure of the original cultivated land, long cultivation period, high transportation cost, poor planting effect, and serious spread of diseases and insect pests. During its entire cultivation process, a large amount of fertilization and watering are required, and the production cost is high. In contrast, soilless lawn has the characteristics of saving land, fast aging, li...
