Abstract: Based on the different irrigation water, the amount of irrigation water and different growth period by the soil conductivity change curve observation. The results show that: The soil conductivity under the influence of irrigation water and plant growth, Strawberry seedlings engraftment period, In the strawberry seedlings engraftment period is strict with the soil electrical conductivity, Need the soil electrical conductivity is less thanS0.30ms.cm_-1,strawberry transplanting survival rate is high. Indicators for soil electrical conductivity(Beginning fertilization in seedling stage need the soil electrical conductivity is less thanS0.30ms.cm_-1and After flowering need the soil electrical conductivity is less thanS0.35ms.cm_-1,) And "quantitative" fertilization, The soil conductivity curve less volatile, Plant growth is moderate, high output.
