Problems solved by technology

Literary balsamica has strong water purification ability and strong tolerance to water pollution. It plays a very important role in the restoration and reconstruction of aquatic ecosystems. Limitations and the biological characteristics of aquatic plants themselves, the survival rate of seedlings planted in water bodies is low, and the growth condition is poor. It is impossible to quickly build underwater submerged plant communities and gradually build underwater ecosystems to achieve the ideal effect of purifying water quality.
[0003] And in the prior art, there is no particularly ideal method that can promote the growth of bitter grass seedlings

Embodiment 1

[0032] The promoting action of embodiment 1 class A microorganism system to the growth of Erythrina galerica

[0033] The Class A microbial system used in this example: according to the mass ratio of 5:3:2, take the mixed thallus of cyanobacteria and spirochete, streptomyces and beneficial bacillus to configure the Class A microbial system, and the Class A microorganism The system is placed under the light of 4000lux, the bacteria are shaken by a magnetic stirrer and inoculated every 3-4 days, and can be put into the water body for cultivating bitter grass seedlings after 12 days.

[0034] Put the bitter grass seedlings in 5 incubators respectively, the temperature of the incubators is 20-30°C, the light intensity is 2500lux, distilled water is installed in the incubators, and 0g / m 3 , 5g / m 3 , 10g / m 3 , 20g / m 3 、40g / m 3 In the Class A microbial system, 5 bitter grass seedlings were placed in each incubator, supplemented by a small amount of intermittent aeration. After 1...

Embodiment 2

[0038] The promoting action of embodiment 2 B type microbial system to the growth of Erythrina galerica

[0039] Class B microbial system used in this example: Nitrosifying bacteria and denitrifying bacteria with a mass ratio of 4:6 were prepared to form a Class B microbial system. Place the B-type microbial system under the light of 4000 lux, shake the bacteria with a magnetic stirrer and inoculate once every 3-4 days, and put it into the water body for cultivating bitter grass seedlings after 15 days.

[0040] Put the bitter grass seedlings in 5 incubators respectively, the temperature of the incubators is 20-30°C, the light intensity is 2500lux, distilled water is installed in the incubators, and 0g / m 3 , 5g / m 3 , 10g / m 3 , 20g / m 3 、40g / m 3 In the B-type microbial system, five bitter grass seedlings were placed in each incubator, supplemented by a small amount of intermittent aeration. After 12 days of cultivating the bitter grass seedlings, the growth conditions are s...

Abstract

The invention relates to the field of environmental engineering, in particular to a method for promoting the growth of bitter grass seedlings and its application. The method comprises the following steps: adding a water body containing microorganisms into an incubator, placing bitter grass seedlings in the water body containing microorganisms for cultivation, supplemented by intermittent aeration. The method of the invention is simple, increases the survival rate of the bitter weed seedlings by more than 10-30%, has low economic cost, is suitable for actual production and application, and has great significance for the rapid growth and reproduction of the bitter weed in eutrophic water bodies.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a method for promoting the growth of bitter grass seedlings and an application thereof. Background technique [0002] Vallisneria Natana, a perennial submerged plant belonging to the family Hydrochardaceae, is one of the most common submerged plants in my country. At present, the problem of eutrophication of water body is being paid more and more attention by environmental scholars all over the world. As an important part of the water ecosystem, submerged plants can absorb nutrients such as nitrogen and phosphorus in the water, and have important ecological value for maintaining the water ecosystem and controlling water eutrophication. Literary balsamica has strong water purification ability and strong tolerance to water pollution. It plays a very important role in the restoration and reconstruction of aquatic ecosystems. Limitations and the biological characteristics o...
