Plant root growth promoting agent

Abstract

The invention discloses a plant root growth promoting agent and belongs to the field of biochemical engineering. The method comprises the following steps: preparing a mycelium seed solution of a mushroom acid-resistant mutant; performing fermental cultivation on the mushroom mycelium, and producing a culture; precipitating or centrifuging the culture, and obtaining the supernatant; separating lentinan from the supernatant, or directly separating the lentinan from the mushroom; measuring composition and structure of sugar; and treating the plant root, stem, leaves or seeds through means of spraying, daubing and soaking or adding coating components by using 0.000001-100 mass percent of lentinan (containing neutral polysaccharides and acidic polysaccharides), so that an effect of promoting growth of the plant root system is achieved. The growth promoting agent is an edible mushroom fermented product and is safe and reliable to animals and plants. According to the growth promoting agent, vigorous growth of the plant root system can be effectively promoted, and the growth promoting agent has slight influence on other organs of plants, is not inhibited by high concentration of substances and is obviously superior to plant hormones or growth regulators. The product can be widely applied to the fields of agriculture and forestry, foods, environment and the like.

Description

technical field [0001] A plant root growth promoter. The product belongs to the field of biochemical industry. The lentinan produced by submerged culture of Lentinus edodes hyphae can effectively promote the vigorous growth of plant roots, and is not inhibited by its high concentration, which is obviously better than other plant hormones or growth regulators. The invention can be widely used in the fields of agriculture, forestry, food and environment to promote root growth of plants. Background technique [0002] Lentinan has a variety of beneficial effects on animals and plants. It is generally extracted from fruiting bodies, which has a long growth cycle and high separation costs. The use of acid-resistant mycelium to implement deep open culture can produce lentinan on a large scale; the advantage of low cost makes the use of lentinan in agriculture and other fields possible. The plant root system is a key organ for plant growth, and cultivation measures have been used...
