Embodiment 1

[0022] Arabidopsis floating cultivation method: refer to the accompanying drawings, which are shown in the figure: 1-foam floating board 2-open container 3-planting hole 4-nylon

[0023] The lower surface of the prepared planting hole is coated with a foam floating plate of 40 mesh nylon mesh and floated in an open container filled with nutrient solution, and Arabidopsis (Arabidopsis Tharliana) seeds are sown on the sand buried in the planting hole. Above, the seeds undergo imbibition and germinate on the third day after sowing. They are cultivated at 25°C, 4000 lux light (10 / 14 light / dark), and 60-70% relative humidity. After 2 hours of aeration for 15 minutes, Arabidopsis seeds matured after 45 days of growth and development.

Embodiment 2

[0025] Rice floating cultivation method: refer to the accompanying drawings, as shown in the figure: 1-foam floating board 2-open container 3-planting hole 4-nylon

[0026] The lower surface of the prepared planting hole is covered with a foam floating plate of 40 mesh nylon mesh floating in an open container filled with nutrient solution, and rice (Oriza Sativa) seedlings are transplanted on the sand grains buried in the planting hole , cultured in a greenhouse under natural light, the nutrient solution was replaced once a week, and the pH of the nutrient solution was adjusted to 5.0 every 3 days. After 75 days of growth and development, the rice seeds matured.

Abstract

The present invention relates to a plant floating cultivation method and its special-purpose equipment. The cultivation method includes the following steps: filling insoluble medium which is acceptable for plant into the planting hole of foamed floating plate, the undersurface of planting hole of foamed floating plate is covered with filtering net whose pore size is less than that of filled medium; preparing nutrient solution required for plant and filling said nutrient solution into the open container; making the above-mentioned foamed floating plate whose planting hole is filled with medium be floated on the nutrient solution surface of the above-mentioned open container; sowing plant seed into the wetted medium, under the condition of proper temp. and light treatment making cultivation.

Description

1. Technical field [0001] The invention relates to a plant cultivation method, which is especially suitable for the field of soilless cultivation. 2. Background technology [0002] At present, among the common plant cultivation techniques, soilless cultivation is an advanced crop cultivation method that utilizes nutrient solution to cultivate plants. Cultivation-based) and substrate (medium) cultivation (solid substrate cultivation) two categories. The method of cultivating plants with an aqueous solution containing plant nutrients as a plant growth medium is called plant hydroponics. Because the hydroponics method can strictly control the concentration of different nutrients in the nutrient solution, it is a plant cultivation method commonly used in plant science research, and it can also be used for factory plant soilless cultivation. The operation step is to put the nutrient solution in the container, the container is covered with a cover with planting holes, the seedli...
