Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 As shown, it is a schematic diagram of the process flow of the present invention. The method for making lawn bricks by using crop straws includes the following steps: A1, crushing straws; A2, sieving and screening the crushed straw debris; A3, feeding the straw particles obtained by screening Add rooting powder, nutrient, water-retaining agent and clay; A4, add binder to the mixture that step A3 obtains; A5, stir; A6, put into mould, pressure molding; A7, implant grass seed, sowing amount It is 160-800g per square meter of lawn bricks, depending on different varieties. Preferably, the straw is wheat or corn straw. Preferably, the particle size range of the straw particles screened is 2-5 mm. Preferably, the water retaining agent is water moss. Preferably, the dosage of the water-retaining agent is 80-100g per squar...

Abstract
The invention discloses a method for manufacturing meadow tiles by crop straws, which comprises the following steps: A1. pulverizing the straws; A2. sieving the pulverized straw scraps by a screen; A3. adding rooting powder, nutritional agents, water preserving agents and clay into the straw grains obtained after the sieving; A4. adding bonding agents into the mixture obtained in the step A3; A5.carrying out stirring; A6. loading the materials into a mold to be pressed and formed; and A7. planting grass seeds with the seeding amount of 160 to 800 g for each square meter of the meadow tile. The meadow tiles produced by the method can be paved in places with the greening requirements, then, grass or bush can grow from the meadow tiles, the meadow tiles are used as carriers of the nutrient and the moisture of the grass or the bush, finally, the meadow tiles become rotten to be merged into the soil, and the invention has the advantages of environment protection and convenient use for the construction by greening workers.
Description
technical field [0001] The invention relates to the field of utilization of agricultural waste, in particular to a method for making lawn bricks from crop straws. Background technique [0002] With the growth of industrial development and the improvement of living standards, the amount of solid waste continues to rise at an alarming rate. In this case, if a large-scale resource recovery system can be established, the use of raw materials will be reduced, and the amount of waste emissions, transportation and treatment will be reduced. This can protect and prolong the life of native resources, reduce costs, reduce environmental pollution, maintain ecological balance, and have significant social and economic benefits. Therefore, the technical development of solid waste recycling is a very meaningful work. [0003] At present, in countries all over the world, especially in developing countries, most of the crop stalks are not used and are discarded. Even if some are partially ...
