technical field

The invention relates to a device for studying the drought resistance of sugarcane at seedling stage by using 1-MCP, and belongs to the technical field of sugarcane physiological and chemical regulation.

Background technique

Sugarcane (Saccharum.spp) is the main sugar crop in the world and one of the excellent energy crops. my country is one of the birthplaces of sugarcane in the world and the third largest producer of sugarcane sugar in the world. In addition to sugar, sugar cane is also used for paper and fuel ethanol production. Cane sugar industry is of great significance to increase farmers' income, adjust industrial structure and ensure national energy security.

1-MCP, namely 1-methylcyclopropene, the Chinese name is 1-methylcyclopropene, which is a kind of cyclopropene compound. 1-MCP is a new type of ethylene receptor inhibitor discovered in recent years. It can irreversibly act on ethylene receptors, thereby blocking the normal combination of ethylene and receptors, and inhibiting a series of effects related to fruit ripening. Physiological and biochemical reactions. As a fresh-keeping agent for fruits and vegetables, 1-MCP has the advantages of non-toxicity, low dosage and high efficiency, and can strongly block the physiological effects of endogenous ethylene, so it has broad application prospects in the storage and preservation of fruits and vegetables. In the application of 1-MCP, there are two problems to be solved: one is that 1-MCP is gaseous at normal temperature and pressure, which is not conducive to storage and transportation; the other is the volume of 1-MCP to produce good fresh-keeping effect The concentration range varies from nl/L to ul/L according to the different types of fruits and vegetables. It is difficult to keep fruits and vegetables fresh if it is higher or lower than this concentration range, so the accurate measurement and control of the concentration of 1-MCP on site is also a One of the urgent problems to be solved.

Since the 1-MCP acting on sugarcane is in a gaseous state, its density is greater than that of air. At the beginning of the experiment, the gaseous 1-MCP will precipitate from the top of the sugarcane sample to be treated to the bottom of the sample in a short time. The time for the sugarcane sample is very short, it is difficult to continue to act, and it cannot meet the purpose of 1-MCP to continue to act on the sugarcane sample to be treated.

Contents of the invention

The purpose of the present invention is to provide a device for studying the drought resistance of sugarcane at seedling stage by using 1-MCP. The device of the present invention can provide a closed small environment, so that the gaseous 1-MCP with a higher density than air can be blown up by the air blower in the closed space to form short-term convection of the up and down airflow, continuously affecting the sugarcane at the seedling stage, In this way, the effect of 1-MCP on sugarcane seedlings can be continuously affected in the study.

The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a device for studying the drought resistance of sugarcane at the seedling stage by using 1-MCP, comprising a box body, one side of the box body is an openable airtight door, and a door is arranged inside the box body.

The working principle of the present invention is: 1-MCP is gaseous at normal temperature and pressure, and its concentration is heavier than air. Through the blower blower, the generated gas flows upward through the small holes on the orifice tube, thereby driving the flow of 1-MCP gas and forming an upward airflow around. The airflow in the middle part is downward, thus forming a convective state. Moreover, when the device of the present invention is working, the door on one side of the opening is sealed, and the whole device is in a sealed state, thereby ensuring that the 1-MCP gas forms an internal circulation inside. In addition, barrel-grown sugarcane is very heavy and needs to be moved by adults. One side of the device of the present invention is an openable airtight door, which can facilitate the staff to enter the device and carry out related operations such as sample movement, loading and unloading, etc. The device of the present invention can also be sealed to play the role of sealing.

The further beneficial effect of adopting the above is that: the frame body of the present invention is set in a back shape, with horizontal bars in the middle, and there are gaps between the horizontal bars to maintain air flow.

Further, the distance between the hole tube and the surroundings of the box is 1/4 of the width of the frame.

The further beneficial effect of adopting the above is that it can not only avoid the blocking of the updraft by the bottom of the bucket containing the sugarcane at the seedling stage, but also facilitate the circulation of the airflow.

Further, a bracket for fixing the orifice is provided under the orifice.

The further beneficial effect of adopting the above is that: the bracket is used to fix the hole tube, and the blower is used to transport the air flow from the lower side to the upper side through the hole tube to form the upper and lower gas convection.
