Abstract

The invention relates to a preparation method of a composite oligosaccharide soil-remediating agent. The preparation method comprises the following steps: 1, preparing trimmed waste fruit tree branches, and carrying out natural air-drying; 2, crushing the air-dried waste fruit tree branches, wherein the diameters of crushed particles are in a range of 0.25-1 mm; 3, sieving the waste fruit tree branches crushed in the step 2; 4, putting fine powder obtained after screening in the step 2 into a tubular carbonization furnace for pyrolysis so as to prepare biochar, wherein a pyrolysis temperatureis selected to be 300-600 DEG C; 5, cooling the biochar prepared in the step 4 to room temperature, spraying an aqueous oligosaccharide solution containing a coupling agent according to a mass ratio of oligosaccharide to biochar of 1: 8000-12000, and carrying out uniform mixing; and 6, drying a mixture prepared in the step 5 to prepare the composite oligosaccharide soil-remediating agent. The composite oligosaccharide soil-remediating agent prepared by adopting the preparation method opens up a new utilization way for a large amount of forest and fruit branch wastes, and has very wide application prospects and high market value.

Description

technical field [0001] The invention relates to the field of agricultural preparations, in particular to a method for manufacturing a composite oligosaccharide soil repair agent. Background technique [0002] my country is a big fruit producing country with a long history of fruit tree cultivation and abundant resources. In recent years, with the rapid development of the fruit industry, the pruning of fruit tree branches has also increased year by year, reaching about 46.5 million tons per year. The traditional processing methods for fruit tree branches are mainly stacking and burning, and stacking takes up a lot of land, and burning causes environmental pollution and wastes valuable biological resources. Therefore, how to turn waste into wealth, rationally utilize this huge waste resource, realize resource utilization and open up a new channel to help farmers increase income has undoubtedly become an important problem that needs to be solved urgently. [0003] In recent y...
