中瑞保水剂 ( PAMN-LC)对无离子水的吸水能力为 67.5ml/g,且随着产品配方和生产工艺的改进 ,其吸水性能有着不断提高的趋势。试验结果表明 ,中瑞保水剂 ( PAMN-LC)吸水总量的 78.4 2 %为有效水 ,无效水所占比例只有 2 1 .58% ;随着保水剂施用量的增加 ,土壤的持水能力也明显增加 ;施用中瑞保水剂PAMN-JCN对提高冬小麦出苗率有明显的效果 ,当土壤含水率介于 1 2 .1 %～ 1 6.8%之间时 ,用保水剂拌种可使冬小麦提早 1～ 3d出苗 ,出苗增加 2 5%～ 31 .7% ;沟施保水剂可使出苗率增加 3.3%～ 8.3% ;施用中瑞保水剂 PAMN-LC,其在苗期的主要作用是促进根系发育、增大根冠比 ,拔节以后则转为促进地上部发育。另外 ,施用中瑞保水剂有利于保持冬小麦叶片较长时间地处于展开状态 ,根系的颜色也比较深 ,多呈浅褐色。
The water absorption capacity of PAMN-LC for deionized water is 67.5ml / g, and the water absorption performance of PAMN-LC has been increasing with the improvement of product formulation and production process. The results showed that 78.4 2% of the total water absorbed by the Chinese and Swiss water-retaining agent (PAMN-LC) was effective water, and the proportion of invalid water was only 21.58%. With the increase of the amount of water-retaining agent, But also significantly increased. The application of Zhongrui water-retaining agent PAMN-JCN has obvious effect on improving the emergence rate of winter wheat. When soil moisture content is between 12.1% ~ 18.8% 1 ~ 3d emergence, germination increased 25% ~ 31 .7%; ditch Shi water agent can make the emergence rate increased 3.3% ~ 8.3%; application Zhongrui water retaining agent PAMN-LC, its main role in the seedling stage is to promote the root system Development, increase the ratio of root to shoot, then join to promote shoot development after jointing. In addition, the application of Zhongrui water retaining agent is conducive to maintaining winter wheat leaves in a long time to expand the state of the root color is also relatively deep, mostly pale brown.
