Problems solved by technology

Up to now, there are only a few reports on the sexual and asexual reproduction of nanchuan koboba in China. The research results all show that the seedling emergence rate is low, and the survival rate of cuttings is only about 10%, which seriously restricts the development of nanchuan koboba. Rescue protection work, therefore, it is imminent to conduct research on key technologies for the breeding of Nanchuan wood pineapple

preparation Embodiment 1

[0032] According to the ratio of chitosan quality: copper sulfate volume is 1 / 4, chitosan is added to the copper sulfate solution with an initial concentration of 15g / L, sulfuric acid is added dropwise to adjust the pH to 4-5, at 40°C, 120W ultrasonic, Oscillate under the condition of 50kHz oscillation frequency for 90min, filter and dry the filter residue with suction to obtain copper-loaded chitosan; add 10 times the volume mass fraction of the obtained copper-loaded chitosan to 2% acetic acid aqueous solution, mechanically stir until dissolved, and then Add cellulose powder with 1 times the weight of chitosan, and stir at room temperature for 2 hours to obtain a mixed solution; cast the obtained mixed solution on a glass substrate, and then dry it at 70°C, then use 2mol / L ammonia solution Soak for 10 minutes, then wash with deionization several times, and dry in vacuum at 65°C, 0.09MPa~0.1MPa for 2 hours to obtain an antibacterial film.

preparation Embodiment 2

[0034]According to the ratio of chitosan quality: copper sulfate volume is 1 / 4, chitosan is added to the copper sulfate solution with an initial concentration of 20g / L, sulfuric acid is added dropwise to adjust the pH to 4-5, at 40°C, 120W ultrasonic, Oscillate under the condition of 50kHz oscillation frequency for 90min, filter and dry the filter residue with suction to obtain copper-loaded chitosan; add 20 times of the obtained copper-loaded chitosan into 2% acetic acid aqueous solution, mechanically stir until dissolved, and then Add cellulose powder twice the weight of chitosan, stir at room temperature for 2 hours to obtain a mixed solution; tape-cast the obtained mixed solution on a glass substrate, dry it at 70°C, and wash it with 3mol / L ammonia solution Soak for 10 minutes, then wash with deionization several times, and dry in vacuum at 65°C, 0.09MPa~0.1MPa for 2 hours to obtain an antibacterial film.

preparation Embodiment 3

[0036] According to the ratio of chitosan quality: copper sulfate volume is 1 / 4, chitosan is added to the copper sulfate solution with an initial concentration of 17g / L, sulfuric acid is added dropwise to adjust the pH to 4-5, at 40°C, 120W ultrasonic wave, Oscillate under the condition of 50kHz oscillation frequency for 90min, filter and dry the filter residue with suction to obtain copper-loaded chitosan; add 15 times the volume mass fraction of the obtained copper-loaded chitosan to 2% acetic acid aqueous solution, mechanically stir until dissolved, and then Add cellulose powder 1.5 times the weight of chitosan, and stir at room temperature for 2 hours to obtain a mixed solution; cast the obtained mixed solution on a glass substrate, and then dry it at 70°C, and use 2.5mol / L ammonia Soak in aqueous solution for 10 minutes, then wash with deionization several times, and dry in vacuum at 65°C, 0.09MPa~0.1MPa for 2 hours, and then obtain an antibacterial film.

Abstract

The invention discloses a sand bed seedling culture method for Artocarpus nanchuanensis S. S.. The method comprises the steps of seed storage, sand bed preparation, seed treatment, seed sowing, management after sowing and seedling transplanting, wherein the seedling culture time is from the end of February to the early March every year or from the end of October to the early November every year. By means of the sand bed seedling culture method, in the sand bed seedling culture process of Artocarpus nanchuanensis S. S., the seed germination rate is high, the artificial propagation cost is low,a technical support is provided for the large-scale artificial propagation and cultivation of Artocarpus nanchuanensis S. S., a material guarantee is provided for the industrialization development ofArtocarpus nanchuanensis S. S. resources, and an important material basis is laid for developing the economic value of the tree species in materials, greening, health care and other aspects in the later period and cultivating Artocarpus nanchuanensis S. S. into a regional characteristic industry; meanwhile, Artocarpus nanchuanensis S. S. is subjected to seedling culture in a sand bed and then is cultured in a container bag so that the afforestation surviving rate can be ensured and the operating cost in production can be reduced; the problem that Artocarpus nanchuanensis S. S. belongs to a fleshy root system, so that the surviving rate in a bare-rooted seedling afforestation mode is low is solved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating seedlings of Nanchuan mupora in a sand bed. Background technique [0002] The 21st century is the century of life sciences, because the research, protection and sustainable use of organisms and their resources will play a key role in addressing challenges related to human survival and development. As the first producer of the ecosystem, plants are extremely important resources for the survival and development of human beings. my country is one of the countries with the richest plant species in the world. However, due to the severe impact of climate change and human activities, some important plant species are already endangered or even on the verge of extinction. It is of great significance to protect and multiply these species so that my country's rich species diversity can be passed on from generation to generation. First discovered in Nanc...
