Paper Title:
Evaluating Anti-Decay Effect of Rice Straw Based on Grey Correlative Method
  Abstract

Anti-decayed rice straw may be used to reinforce saline soil in inshore of Northern China. Water absorption, maximum elongation and maximum tension of rice straw, including rice straw soaked in seawater, running water and seawater after SH agent has been tested, and anti-decay effect is evaluated based on grey correlative method. The experimental results showed that water absorption of rice straw soaked in seawater and running water increased with soaking time. And maximum elongation and maximum tension decreased with soaking time. The reduction rate of water absorption was the greatest when the rice straw was soaked in seawater after SH agent for 14-day and which had the biggest maximum elongation and maximum tension yet. According to grey correlative method, the relational degrees of water absorption, maximum elongation and maximum tension for 14-day are the biggest. It means that anti-decay effect is the best in this condition. Taking rice straw which soaked in seawater after SH agent for 7-day as example, correlation coefficients of water absorption, maximum elongation and maximum tension increase with soaking time. It indicates that the longer soaking time is, the better anti-decay effect of rice straw is. Evaluating anti-decay effect of rice straw according to grey correlative method and analyzing the laboratory results respectively, they are highly consistent. Grey correlative method is a suitable one for evaluating the anti-decay effect of rice straw.
