Abstract

The invention relates to a preparation method of composite oligosaccharide fruit and vegetable root nourishing element. The preparation method comprises the following four steps: crushing a chitosan raw material, acid-dissolving chitosan powder, performing enzymolysis on a high-viscosity chitosan solution, and compositing carboxymethyl chitosan and oligosaccharide. A field trial proves that a product has the effect of promoting the growth of fruit and vegetable roots, nourishing and protecting the roots and strengthening the roots and seedlings; and the composite oligosaccharide fruit and vegetable root nourishing element has the effects of improving and restoring soil, optimizing a rhizospheric microorganism ecological system, and inhibiting the occurrence and development of soil-borne disease, and is suitable for the green-house fruit and vegetable cultivation. By applying the product disclosed by the invention, the use amount of chemical fertilizer and pesticides can be reduced, thepesticide residue pollution of an agricultural product can be reduced, and the quality and the economic benefit of the agricultural product can be improved.

Description

technical field [0001] The invention relates to a preparation method of a compound oligomeric candy and vegetable root nutrient, belonging to the technical field of bioprocessing. Background technique [0002] The soil in the farmland, especially the soil in the greenhouses of fruits and vegetables, due to the application of more chemical fertilizers and pesticides, has caused more and more phenomena such as soil acidification, compaction, and salinization, resulting in a decline in soil fertility, weak fruit and vegetable root systems, and poor stress resistance. Severe rhizosphere diseases and many dead trees have seriously affected the quality and output of fruit and vegetable products. In this case, only by reducing the application of chemical fertilizers and pesticides, increasing the application of organic fertilizers and new fertilizers for fruit and vegetable root maintenance, and creating soil that is easy for fruit and vegetable roots to grow and rhizosphere enviro...
