Problems solved by technology

[0007] The purpose of the present invention is to overcome the fact that chemical fertilizers in the prior art have great harm to the soil and the environment, and at the same time, the effect of using arbuscular mycorrhizal fungi alone is not good, and the root system of plants cannot be developed more when used alone, resulting in the inability to grow in the soil. The problem of absorbing sufficient nutrients for growth provides a method that avoids the use of chemical fertilizers and enables the synergistic combination of arbuscular mycorrhizal fungi and S-induced antibiotics to stimulate effective growth of plant roots and make them from A synergistic composition comprising arbuscular mycorrhizal fungus and S-attractin for further strengthening the ability to absorb nutrients in the soil and improving the growth effect of plants and the method for regulating plant growth

Abstract

The invention relates to the field of agricultural chemicals, in particular to a synergistic interaction composition containing arbuscular mycorrhizal fungi and S-abscisic acid and a method for regualting plant growth with the synergistic interaction composition. The composition comprises components which exist in the synergistically-effective quantity and are used as active components of (1) thearbuscular mycorrhizal fungi and (2) a plant growth regulating agent namely the S-abscisic acid. The composition overcomes the defects that a chemical fertilizer has serious damage to soil and environment, is poor in effects when the arbuscular mycorrhizal fungi are separately used, and the immunity of crops for various adverse weather and medicine damage, drought and flood disaster and the like cannot be effectively improved. The composition has the following beneficial effects that (1) the arbuscular mycorrhizal fungi and the S-abscisic acid are in synergistic interaction and combination, sothat the root system growth of plants is vigorous, the yield of the crops is further increased, the capacity of the crops for resisting damage and adverse weather can be reinforced; (2) the composition is long in action time and free from environment pollution; (3) the culturing and preparing method is simple, and the activity is high; and (4) the synergistic interaction composition is simple inthe application method.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a synergistic composition comprising arbuscular mycorrhizal fungi and S-induced antibiotics and a method for regulating plant growth. Background technique [0002] Mycorrhizae are a common plant symbiosis phenomenon in nature, which is a combination of mycorrhizal fungal hyphae in soil and vegetative roots of higher plants. The symbiotic fungi obtain the necessary carbohydrates and other nutrients from the plants, and the plants also obtain the required nutrients and water from the fungi, so as to achieve a high degree of unity of mutual benefit and mutual exchange. It not only has the characteristics of general plant roots, but also has the characteristics of obligate fungi. [0003] For the influence of plant physiological traits, mycorrhizal fungi can promote the absorption and utilization of N, P, K and some trace elements by plants, improve the nutritional status of plants, and si...
