The present invention provides a method for intercropping and cultivating konjak by a northern high-stem plant, which is characterized by comprising the following steps: A, intercropping and cultivating the konjak in a forest land or a corn field, applying 1 to 2 tons of decomposed organic fertilizer for each mu, then spreading 100 jins of calcined lime over each mu to sterilize the soil, and turning over and flattening the field; B, sterilizing konjak seeds; C, adopting ridge culture and oblique culture to intercrop 3 to 5 rows of konjak at a konjak ridge height of 20 to 30 centimeters, a ridge surface width of 20 to 25 centimeters and a forest belt of 3 to 5 meters, or intercropping 1 to 2 rows of konjak in a corn row, and inclining the seeds for 45 degrees facing the sun; and D, performing grading seeding, wherein the planting density uses 6 to 8 times diameter of the konjak seed as a row space and 4 to 5 times diameter of the konjak seed as a plant space, and covers 15 to 20 centimeters of soil. By adopting the technical scheme of the present invention, the increment amplitude of intercropping the konjak in the forest land is 3 to 7 times that of the primary seeds, the per mu yield reaches more than 1,500 kilograms, the utilization efficiency of the forest land is improved by over 20 percent, the economic benefit in each mu is increased by more than 2,000 yuan, and the utilization path of the forest land is effectively broadened.

The invention relates to a method for preparing a biomass adhesive from alfalfa meal. The method comprises the following steps of: weighing the alfalfa meal, soaking the alfalfa meal into water, adding ethanol, stirring uniformly and filtering; adjusting the pH of the filtrate, then heating the filtrate, preserving the heat, cooling to room temperature, filtering, and drying filter cakes; weighing the filter cakes, putting the filter cakes into a three-necked bottle filled with distilled water, adding sodium dodecyl benzene sulfonate, heating for a period of time, dripping NaOH, adjusting the pH of the solution to 9, adding poly(phenyl methylene isocyanate), and reacting, thus obtaining the biomass adhesive. By adopting the method, the biomass adhesive with good adhesive property is prepared from the meal raw material of alfalfa with wide planting area, high yield and reproducibility, a deep processing product of the alfalfa with industrialized value is obtained, the additional value is improved, meanwhile, the obtained adhesive does not contain the components such as formaldehyde and aromatic hydrocarbon harmful to human bodies, the cost is low, the process is simple, and the adhesive can be applied in the fields of wood veneers, shaving boards, fiber board and the like.
