Abstract

The invention relates to the field of plant cultivation. According to the technical scheme, a preparation method of a foam base material special for cultivation includes the following steps that (1) biomass liquefaction product resin is prepared, specifically, 1, the following raw materials in parts by weight: 100 parts of a biomass raw material, 30-90 parts of a composite liquefying agent, 15-25parts of a catalyst for liquefaction, 20-40 parts of a basic catalyst and 40-80 parts of formaldehyde are prepared, and 2, a reaction still is heated to 60DEG C, the composite liquefying agent, the biomass raw material and the catalyst for liquefaction are added and stirred at a constant speed, after the temperature is raised to 120-130DEG C, heat reaction is carried out for 10-30 minutes, the reaction is stopped and the temperature is lowered to 60DEG C, the alkaline catalyst is added to adjust the pH value to alkaline, the formaldehyde is added, the temperature is raised to 85-95DEG C, the temperature is kept for 20-30 minutes, and the reaction is stopped and the temperature is lowered to 60DEG C to obtain the biomass liquefaction product resin; and (2) the foam base material special forcultivation is prepared. The foam base material special obtained by the preparation method has an environmental-friendly characteristic.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a preparation method and a cultivation method of a special foaming matrix material for cultivation. Background technique [0002] Modern agriculture and forestry is to use certain facilities and engineering technology to change the natural environment, simulate and control plant growth environmental factors such as temperature, light, humidity, water, etc., to create the best environment that meets the growth and development requirements of plants or microorganisms.
