- Title:
- Selection of The Bolus Type and Dosage for Polyacrylamide to Control Water and Soil Erosion in Hilly Fields
- Keywords:
- polyacrylamide; bolus type; dosage; control erosion
- 摘要:
- 通过室内聚丙烯酸胺不同剂型、不同浓度、经济剂量和持久性防蚀效果试验，筛选出防治田间土壤侵蚀的最佳剂型为PHP300～400万，最佳浓度为10×10－6～40×10－6，持久性试验结果表明：在8次扰动土壤的情况下，防治水土流失效果下降50%左右，其作用大约可持续2～3年。
- Abstract:
- Through the experiments under the various bolus type and dosage, economic and enduring control erosion,the optimum selected to harness field soil erosion is polyacrylamide 3.00~4.00 million, 10×10-6~40×10-6. Under the eight times harnessing soil,the quantity of soil erosion was reduced to 50% more, the control result can enduces 2~3 years by use of PHP.
