Cultivation chamber capable of flexibly controlling growth condition of potato seedling

Abstract

The invention discloses a cultivation chamber capable of flexibly controlling growth conditions of potato seedlings. The cultivation chamber comprises a support. Sidewalls are arranged around the support. A transparent roof is arranged over the sidewalls. A shading apparatus is arranged below the transparent roof. Seedling holding racks are arranged below the shading apparatus. Radiators are arranged in a cultivation space surrounded by the sidewalls. The radiators are connected with a boiler. One sidewall, facing the radiators, is provided with an air draft device. One sidewall, next to the air draft device, is provided with water curtains. One sidewall, opposite to the water curtains, is provided with negative pressure fans. The shading apparatus comprises a first shading unit. The first shading unit is connected with the head end of a long tooth bar through a first latch hook device. The tail end of the tooth bar is connected with a second shading unit through a second latch hook device. The long tooth bar is engaged with a transmission gear. The transmission gear is connected with a deceleration mechanism through a transmission rod. The deceleration mechanism is connected with a driving motor. Growth conditions of potato seedlings are set according to set test conditions so as to be controlled precisely. Moreover, control is flexible, and test data is accurate.

Description

technical field [0001] The invention relates to a cultivation chamber used in the field of seedling cultivation, in particular to a cultivation chamber capable of flexibly controlling the growth conditions of potato seedlings. Background technique [0002] Potato (scientific name: Solanum tuberosum), a perennial herb belonging to the Solanaceae family, with edible tubers, is the third most important food crop in the world, second only to wheat and corn. Potatoes are also known as ground eggs, potatoes, Yang Shanyu, etc., the tubers of Solanaceae plants. Together with wheat, corn, rice, and sorghum, it has become the world's top five crops. Potatoes are native to the Andes in South America, and the history of artificial cultivation can be traced back to the southern part of Peru from about 8000 to 5000 BC. The main potato producers are China, Russia, India, Ukraine, and the United States. China is the country with the largest potato production in the world. In 2015, China...

Problems solved by technology

[0003] At present, the test of cultivating new potato seedlings is mainly carried out in plastic greenhouses. The disadvantage of this cultivation is that it is difficult to achieve fine control of the growth conditions of the seedlings, which makes it difficult to cultivate the seedlings according to the established test conditions. thus affecting the test results
