Water retention and salt isolation grass planting medium and method using the same to plant drought resistant and salt resistant ecological grass

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...

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, the salt content of the planting substrate layer will increase due to salt return, and it will degenerate into saline soil, which is no longer suitable for the growth of turfgrass, and the turf will die under salt stress.

[0010] However, these lawn planting matrix materials do not have excellent water retention, fertilizer retention performance, and excellent salt isolation ability. Build a high-resistance, low-consumption ecological lawn with drought and salt tolerance
