preparation example Construction

[0029] Preferably, the preparation method of the nutrient solution comprises: after mixing calcium nitrate, boric acid, biotin, choline, gibberellin and water in a weight ratio of 1:(500-1500), to obtain the first mixture; The mixture is mixed with water according to the weight ratio of 1:(200-800) to obtain the second mixture; after mixing the first mixture and the second mixture, the pH value is adjusted to 5.5-6.5 to obtain a nutrient solution.

[0030] Preferably, in root-promoting culture, the nutrient solution is sprayed in the form of spray; the spraying method is: spray the nutrient solution twice a day; liquid.

[0031] Preferably, during the colonization process, the sterilized plants are colonized in the colonization cup, the lower half of the colonization cup is filled with a substrate, and the filling amount of the substrate accounts for 1 / 2-2 / 3 of the volume of the colonization cup.

[0032]Preferably, the disinfectant is made of the following raw material compo...

Embodiment 1

[0036] At the beginning of May, select a Dendrobium officinale plant that is robust, free from diseases and insect pests, has 3 root systems and the length of each root system is 3 mm as the mother plant, rinses and intercepts 2 / 5 of the root amount; soaks the root-cut Dendrobium officinale plant Take it out after 200s in the disinfectant; the disinfectant is composed of 3 parts by weight of potassium permanganate aqueous solution with a mass percent concentration of 0.1%, 5 parts by weight of an aqueous solution of sodium hypochlorite with a mass percent concentration of 0.02%, and 1 part by weight of chlorothalonil , and in specific preparation: after mixing each raw material component and water according to a mass ratio of 1:1000, adjust the pH value to 6.0 to obtain a disinfectant. The sterilized Dendrobium officinale plant is planted in a planting cup filled with a matrix, the filling amount of the matrix accounts for 1 / 2 of the volume of the planting cup, and the matrix c...

Embodiment 2

[0038] At the beginning of June, select a Dendrobium officinale plant that is robust, free from diseases and insect pests, has 2 root systems and the length of each root system is 5mm as the mother plant, rinses and intercepts 3 / 5 of the root amount; soak the root-cut Dendrobium officinale plant Take it out after 500s in the disinfectant; the disinfectant is composed of 3 parts by weight of potassium permanganate aqueous solution with a mass percent concentration of 0.2%, 8 parts by weight of an aqueous sodium hypochlorite solution with a mass percent concentration of 0.01, and 2 parts by weight of chlorothalonil. And in specific preparation: after mixing each raw material component and water according to the mass ratio of 1:500, adjust the pH value to 7.0 to obtain the disinfectant. The sterilized Dendrobium officinale plant is planted in a planting cup filled with a matrix, the filling amount of the matrix accounts for 2 / 3 of the volume of the planting cup, and the matrix con...

Abstract

The invention relates to a plant hydroponic culture method. The method includes steps: stock plant selection, to be more specific, flushing to clean a stock plant, cutting roots, and sterilizing the plant subjected to root cutting; planting, to be more specific, planting the sterilized plant into a matrix; root promoting culture, to be more specific, subjecting the plant planted in the matrix to root promoting culture under appropriate temperature and relative humidity and preset illumination conditions, wherein in a root promoting culture process, nutrient solution is sprayed, and when root system quantity of the plant is larger than or equal to eight, and the length of each root system is larger than or equal to 5cm, root promoting culture is stopped. By the plant hydroponic culture method, utilization of expensive intelligent culture systems in a traditional hydroponic culture process is avoided. In addition, the plant hydroponic culture method is simple and feasible, the plant survival rate can be increased remarkably, production cost in a culture process can be reduced while plant root promoting time is shortened, and accordingly the plant hydroponic culture method is remarkably improved both in terms of cost and economy.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a plant hydroponic method. Background technique [0002] Soilless cultivation technology is one of the most advanced and capital-intensive production methods widely used in protected agriculture in the world, and has thus become one of the main directions of research and development of protected horticulture in the world in the past century. Among them, soilless hydroponics cultivation technology is a newest cultivation method researched along with the development of greenhouse production. Specifically, nutrient hydroponics is a new type of plant soilless cultivation method, also known as hydroponics and hydroponics. It induces and domesticates ordinary plants that grow in the soil for a long time through biological, chemical and physical technical means. , cultivate, and transform it into a new generation of high-tech biotechnology means that can grow and devel...
