Problems solved by technology

However, the existing planting matrix materials do not have the function of isolating saline soil and planting matrix, or binding Na+
Due to the high groundwater level in coastal tidal salt land, in the rainy season with heavy rainfall or when drainage is not timely, Na+ in the original saline soil at the bottom of the lawn will move back to the upper layer as the groundwater level rises. Improvement by guest soil method In the overgrown lawn planting substrate layer, t

Example Embodiment

[0052] Example 1 Use the planting substrate material and process of the present invention to build a water-saving and drought-resistant lawn

[0053] (1) Remove trees, shrubs and herbaceous plants on the ground of lawn construction, and clean up bricks, stones and construction waste that affect the construction of lawn construction and the normal growth and development of lawns;

[0054] (2) Remove the surface soil with a thickness of about 30cm, level the ground, and make a flat ground base;

[0055] (3) Stack the eradicated surface soil uniformly, seal it with agricultural film, and fumigate with brominated benzene to kill pests, weeds and other harmful biological sources;

[0056] (4) Mix bentonite and coarse river sand according to the volume ratio of 75:25, and evenly lay it on the ground base with a thickness of 10cm, and then use a 200kg iron roller for proper suppression to form a smooth water-retaining and salt-retaining layer;

[0057] (5) Mix harmlessly treated pastoral soil,...

Abstract

The invention discloses a water retention and salt isolation grass planting medium and method using the same to plant drought resistant and salt resistant ecological grass. The grass planting medium comprises a water retention medium; the water retention medium is prepared from, by volume, 50%-55% of farm soil, 30%-40% of vermiculite, 10%-20% of peat soil, 5%-8% of bentonite, totally 100%; a water retention salt isolation layer material is prepared from, by mass, 75%-85% of bentonite and 15%-25% of coarse river sand, totally 100%. The water retention and salt isolation grass planting medium has dual water retention capacity, and has the advantages of being high in water storage amount and long in water retention aging, the salt isolation effect is remarkable, wetland grass can be prevented from returning salt, and the grass salt resistance capacity is extremely remarkably improved.

Description

technical field [0001] The invention belongs to the field of lawn planting, and relates to a water-retaining and salt-isolated lawn planting substrate and a method for using it to build a drought-resistant and salt-resistant ecological lawn. Background technique [0002] The lawn has various functions such as greening, beautifying the environment, inhibiting bacterial reproduction, absorbing particles and toxic and harmful gases in the air, purifying the air, increasing humidity, and improving the microclimate. Therefore, it is widely used in landscaping, sports venues, and family indoor greening and beautification etc. [0003] In the process of lawn production and planting, the lawn planting substrate is inseparable. The lawn planting substrate plays the role of water retention, fertilizer preservation, provision of nutrients, and fixing the root system of the lawn, providing a place for the growth and development of the lawn. High-quality lawn planting substrate can prod...
