| Abstract: | The tests of salt and alkali tolerance of wheat and corn showed that the salt tolerant ability of wheat is more powerful thancorn, whereas, the alkali tolerant ability of wheat is weaker than corn in their growth periods. The leaching fraction is about4.4%~7.5% when we utilize the alkalized and mineralized water with the mineralized degree of 0.5~3.5g/L, accordingly thesupplementary water is 3 18l~3357m3/hm2 in wheat field and 2276~2465m3/hm2 in corn field. |
