【Abstract】 This paper described thc comparisons of the yield-power of cucumbers individually grows undcr the conditions of water,sand and soil cultures,uscd thc pot culture in the glasshouse.It was discovcrd that(1)the growing spced of young plants in water culture was obviously fastcr than those in sand and soil cultures;(2)the ana- omical structures of roots,stems and leaves under the three treatments in different gr- owth duration were idcntical with the ecological observation results;(3)both thc yield and the qualities of cucumbers in water culture were superior to that in sand and soil cultures.In additiom,the yield was far higher in sand culture than ttha in soil culture.It was considered that thc different environments rounded the roots(inclu- ding nutrient,aeration,temperature and moisture)were the main reason that caused the results described above.更多还原
