The invention relates to the field of a floor production process, in particular to a method for making an impregnated paper laminated highly wear-resistant grass-wood composite floor, which comprises the following steps: (1) separating grass into fiber by using fiber separating equipment, mixing the fiber and wood fiber according to the ratio of 1:1-2, adding 8-12% (weight percentage) of urea-formaldehyde resin adhesive and 0-2% (weight percentage) of curing agents, and then carrying out pavement and hot pressing to form grass-wood composite boards; (2) pressing and sticking a decorating layer on the grass-wood composite boards; (3) dividing; (4) maintaining; and (5) slotting. The grass comprises rice straw, Pennisetum alopecuroides or Pennisetum purpureum and the like. The method has the beneficial effects that on the one hand, the grass-wood composite boards made by mixing the grass fiber and the wood fiber can be directly used for producing floor substrates by using urea formaldehyde resin; and on the other hand, the processability of the product can be greatly improved, and the function of aldehyde reduction of the grass fiber can reduce free formaldehyde release of the floor so that the purpose of environmental safety can be achieved.

The invention belongs to the field of crop fertilizer, in particular relates to synergistic ecological fertilizer special for radix astragali and a preparation method of the synergistic ecological fertilizer. The synergistic ecological fertilizer special for the radix astragali is prepared from the following components by a certain weight proportion: sorghum halepense stalks, Chinese pennisetum, palm leaves, wormcast, a starter culture, charcoal, amino-bentonite, phosphorite powder, urea, potassium sulphate, microelements, fructo-oligosaccharide and jasmonic acid methyl ester. The ecological fertilized provided by the invention takes natural organic matters as main materials, green and environmental protection is achieved, crops can be promoted to rapidly grow, meanwhile the fructo-oligosaccharide and the jasmonic acid methyl ester are added in the mixed fertilizer, a secondary metabolism process of the radix astragali is promoted, the content of astragalus polysaccharide is increased, and the quality of the radix astragali is improved. The synergistic ecological fertilizer is reasonable in formula, and overall and balanced in nutrition, the utilization rate of fertilizer effect can be obviously improved, the yield and quality of the radix astragali can be greatly improved, the soil environment can be improved by long-term application of the ecological fertilizer, the capacities of fertilizer conservation and fertilizer supply and the buffer capacity of the soil can be enhanced, the occurrence of damage by disease and insect can be reduced, and the economic benefit of the radix astragali can be improved.
