| 1 | The Salt Reduction and Yield Increase Effects of Smashing Ridging Transforming Saline-alkali Land and Its Development Prospects显示文摘Using smashing ridging tillage machine and smashing ridging technology invented by the authors,transformation test of saline-alkali land by smashing ridging was conducted respectively in Xinjiang and Shaanxi during 2015-2016. The results showed,in severe saline-alkali soil of Xinjiang,after growing cotton by smashing ridging,total salt in soil decreased by 31. 31%,cotton production increased by 48. 80%,and salinity level declined from severe to moderate; in mild saline-alkali soil of Shaanxi,after growing summer corn by smashing ridging,total salt in soil decreased by 42. 37%,corn yield increased by 34. 83%,salinity degree changed from mild desalination to normal farmland; in Ningxia,Inner Mongolia,Gansu,Jilin,Henan,Hebei,and so on,smashing ridging tillage practice in different types of saline-alkali land was conducted; according to the salt reduction and yield increase effects of saline-alkali land after smashing ridging,the development prospect of smashing ridging technique in improvement and application of saline-alkali land was proposed. | Wei Benhui Shen Zhangyou Zhou Jia Zhou Lingzhi Gan Xiuqin Lao Chengying Li Yanying Hu Po | 2018 | Meteorological and Environmental Research2018，9，4： | 3 |
