This
kind of rope is super wear resistance, soft and high safety. Fiber elongation
at break is about 3% which is far lower than the steel wire rope and other
chemical fiber rope. It is low density, light weight. Product performance is
stable, anti-corrosion, acid and alkali resistant. The rope is aging resistance,
UV protection, and long service life.

When each test material was found in the ear, 2é’µ of each material was transferred to the artificial climate chamber for high temperature treatment; in the artificial climate chamber, the materials were randomly arranged and re-arranged once a day to eliminate position-induced Error; the remaining 2 æ¯ per material was still grown under natural conditions as a control. About 7 days after the material was processed, all the panicles were extracted and flowering was completed, removed from the artificial climate chamber, and returned to natural conditions.
At maturity, the solids and empty pellets of the high temperature-treated material and the corresponding material not subjected to high temperature treatment (grown under natural conditions) were tested and the seed setting rate was calculated. The evaluation index of the heat resistance is expressed by the heat resistance coefficient, the heat resistance coefficient (%) = (the seed setting rate under the natural conditions - the setting rate of the high temperature treatment)/the setting rate under the natural conditions @ 100. Heat resistance coefficient [T226 is more resistant to high temperature type, heat resistance coefficient\T219 is high temperature sensitive type, heat resistance coefficient> T226 or
In the process of studying the heat resistance of rice, it is necessary to control the temperature, light and humidity. In this situation, the application of the artificial climate chamber is indispensable. A continuous 2a high temperature identification method for rice materials with different heat tolerance and heading flowering period was studied. Since the artificial climate room can be used to simulate the environment under natural conditions, and the high temperature, light and humidity can be accurately controlled, the results can be repeated and the results obtained are more accurate and reliable.
The evaluation and utilization of rice germplasm resources can not be separated from the identification of rice heat resistance. Accurate and scientific identification methods are the key to study this characteristic. During the long-term planting process, it was found that rice is most sensitive to high temperatures during flowering, and the maximum daily temperature of 35°C in the heading and flowering period of rice is the critical temperature for heat damage. The seed setting rate is most sensitive to high temperatures. Thirty rice materials with different degrees of tolerance to high temperature, T226 with high temperature tolerance and T219 sensitive to high temperature were used as control materials. Artificial climate chambers were used to simulate the high temperature environment under natural conditions, and rice heat tolerance identification methods were studied for rice production. Scientific guidance for the evaluation and use of heat-resistant germplasm resources.
