Water culture facility and water culture method for Chinese ilex seedling cultivation

Abstract

The invention relates to a water culture facility and water culture method for Chinese ilex seedling cultivation. The water culture facility for Chinese ilex seedling cultivation includes a cultivation room, a solution preparation device, a sewage pool, and a control device; a cultivation pool is arranged under the cultivation room; quartz sand is laid in the cultivation room; the cultivation chamber communicates with the solution preparation device and the sewage pool through an input pump and an output pump respectively; the flow of the output pump is greater than the flow of the input pump;and the control device is used for controlling the input pump and the output pump to operate. In addition, the invention also provides a water culture method for Chinese ilex seedling cultivation. The water culture method includes: using the water culture facility to adjust the temperature and ventilation of the cultivation room, and changing a cultivation solution. The technical scheme can achieve automatic control of Chinese ilex water culture, can avoid influence of nutriment solution changing on the Chinese ilex, can reasonably process the used nutriment solution, can protect an environment, and can promote the growth of the Chinese ilex.

Description

technical field [0001] The invention belongs to the field of plant hydroponic technology, and in particular relates to a hydroponic facility and a hydroponic method for raising holly seedlings. Background technique [0002] Ilex is an evergreen tree, mainly distributed in Zhoushan Islands, Zhejiang Province, my country, and is listed as a rare and endangered plant in Zhejiang Province. Ilex is not only a beautiful green book, but also has strong drought resistance, salt resistance, and barrenness. It is an ideal tree species for afforestation and ecological restoration in regions and islands. However, for a long time, the natural resources of holly have been continuously damaged by human social activities, making this tree species gradually become endangered. It is of great significance for the protection of nature and the development and utilization of plant resources. The propagation of holly usually adopts two methods of sowing or cutting, but these two traditional propaga...

Problems solved by technology

The propagation of holly usually adopts two methods of sowing or cutting, but these two traditional propagation methods all use soil cultivation, which has the disadvantages of difficult control of nutrients, complicated management, and easy occurrence of plant diseases and insect pests. In the prior art, the publication number is "CN106688847A "'s patent document discloses a hydroponic method of Holly holly, which belongs to the field of plant hydroponic technology

The hydroponic method is as follows: after sterilizing and rinsing the roots of Holly holly seedlings, transfer them to a hydroponic box filled with nutrient solution for cultivation; wherein, each 1L of nutrient solution is composed of the following ingredients: ammonium dihydrogen phosphate 0.5- 1.5g, potassium nitrate 1.5-2g, ammonium nitrate 0.15-0.2g, calcium dihydrogen phosphate 0.1-0.5g, calcium sulfate 0.02-0.03g, magnesium sulfate 0.1-0.15g, ferrous sulfate 0.01-0.03g, sodium tetraborate 0.002-0.004g, manganese sulfate 0.001-0.003g, copper sulfate 0.001-0.003g, zinc sulfate 0.0005-0.0015g, and the balance is sterile water. When using this method, after the holly will absorb the nutrients in the nutrient solution, the remaining The nutrient solution also contains a large amount of salt components. Since these remaining nutrient solutions are not treated, the environment is polluted. On the other hand, due to the need to transplant the holly After reaching the free area, replace the nutrient solution and then transplant the holly to the original position, which increases the labor intensity of the operator and reduces the labor efficiency. During the replacement process, the holly cannot absorb nutrients, which has adverse effects on the growth of the holly. In addition, when the nutrient solution is used, because it is not used in a closed environment, some nutrients in the nutrient solution react with oxygen and nitrogen in the air, which affects the absorption effect of holly on nutrients
