Optimized plough layer of natural football field lawn and preparation method thereof

Abstract

The invention discloses an optimized plough layer of a natural football field lawn and a preparation method thereof. The optimized plough layer comprises the components in percentage by volume: 50%-75% of medium coarse sand or fine sand, 10%-20% of vermiculite, 10%-20% of perlite and 5%-10% of organic fertilizer. The optimized plough layer of the natural football field lawn has the advantages of being moderate in hardness, good in water retention and water permeability, moderate in horizontal traction force, good in elasticity and the like; the requirement of sports on the field surface is met, meanwhile, the normal growth requirement of lawn grass is met, and the requirements conform to or approach to the national standard; the preparation method is simple to operate, easy to implement, low in cost and suitable for actual production.

Description

technical field [0001] The invention relates to a lawn cultivation layer, in particular to a natural lawn optimization cultivation layer suitable for football fields, tennis courts, rugby fields or golf greens. Background technique [0002] The lawn bed is the overall soil on which turfgrass grows, and is the carrier and growth medium of turfgrass, including the plowing layer and the drainage layer below. The tillage layer is the site foundation of turfgrass, which affects the quality and durability of the turf. An ideal cultivation layer should have good permeability, good elasticity, good water retention and moderate fertility. It not only meets the requirements of the sports itself on the surface of the field, but also meets the requirements of the normal growth of turf grass, and a balance must be struck between the two. [0003] In the prior art, Chinese patent CN107258513A discloses a planting substrate, but the substrate is mainly peat soil. Because the peat soil it...

Problems solved by technology

[0003] In the prior art, Chinese patent CN107258513A discloses a planting substrate, but the substrate is mainly peat soil. Because the peat soil itself is relatively soft, the substrate for gardening flowers still meets the requirements, but in football fields or golf courses. The field of sports turf has high requirements on the mechanical properties of the turf itself, whether it is its own strength, horizontal traction or elasticity, etc., so the substrate cannot meet the requirements of sports turf
