Abstract

The invention relates to a plant functional combination for the planting in an arenaceous fluctuating zone of a reservoir area, which is characterized in that: acorus calamus seeds, a soil substrate, an organic fertilizer and a biological bonding agent are mixed and stirred in water uniformly according to a weight ratio of 1:(85-95):(5-10):(1.5-2.5), and 5 to 10 granules of the acorus calamus seeds are used as a sticky dumpling to obtain the plant functional combination, wherein the moisture content in the plant functional combination is between 40 and 65 percent, the content of N, P and organic matter in the organic fertilizer is between 10 and 20 g/kg, between 1 and 1.2 g/kg and between 35 and 60 g/kg respectively, and the biological bonding agent is prepared from starch, protein, dextrin and rosin in a ratio of (20-25):(5-10):(55-60):(10-15). The plant functional combination has the advantages that: the survival rate of plant seeds in the fluctuating zone is more than 30 percent; vegetation community of the arenaceous fluctuating zone of the reservoir area can be restored; and soil erosion is reduced.

Example Embodiment

[0016] Example 1
[0017] The present invention is a plant function complex for planting in the sandy water-leveling zone of the reservoir area, which is composed of water calamus seeds, soil matrix, organic fertilizer and biological adhesive in a weight ratio of 1:85:5:1.5. Evenly, then take 5-10 calamus seeds as a sticky mass to obtain a plant functional complex. The moisture content of the plant functional complex is 40%, and the N, P and organic matter content in the organic fertilizer are 10-20g/kg respectively , 1-1.2g/kg, 35-60g/kg, the bio-adhesive is made up of starch, protein, dextrin and rosin in a mass ratio of 23:6:57:14. The soil matrix is ​​a natural soil Let it dry, crush, and pass through a 50-mesh sieve.

Example Embodiment

[0018] Example 2
