Device for researching drought resistance of sugarcane in seedling stage through 1-MCP

Abstract

The invention discloses a device for researching drought resistance of sugarcane in the seedling stage through 1-MCP and belongs to the technical field of sugarcane physiological and chemical control. The device comprises a box, one side of the box is provided with a sealing door capable of being opened and closed, a frame arranged in the box, a porous pipe below the frame, and an air blower connected with one end or two ends of the porous pipe. The frame surrounds and is annularly distributed on the inner side wall of the box. A plurality of transverse rods are arranged on the frame at equal intervals. A bucket containing sugarcane in the seedling stage is arranged on the transverse rods. The four corners of the frame are each provided with a wild-mouth bottle containing 1-MCP. The device can provide a closed small environment so that gaseous 1-MCP with the density larger than that of air can be contained in the closed space, gas on the lower portion is blown upwards by means of the air blower to form short-time convection of upper airflow and lower airflow, sugarcane in the seedling stage is continuously influenced, and accordingly the effect that 1-MCP continuously influences sugarcane seedlings in research is achieved.

Description

technical field [0001] 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 [0002] 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. [0003] 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 n...

Problems solved by technology

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

[0004] 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 sugarcane samples is very short, it is difficult to continue to act, and it cannot meet the purpose of 1-MCP to continue to act on sugarcane samples to be treated
