摘要： 通过对不同种植地灌溉水源、灌水量及不同生长期土壤电导率变化曲线观测及采用几种不同施肥方式对比试验,研究施肥对土壤电导率以及草莓植株生殖生长的影响。结果表明：土壤电导率受灌溉水源、植株生长量影响,草莓幼苗定植期对土壤电导率要求较严格,要求土壤电导率小于0.30ms.cm-1,草莓移栽成活率高。以土壤电导率为指标(幼苗期土壤电导率小于0.30ms.cm-1,开花后土壤电导率小于0.35ms.cm-1时开始施肥)并“定量”施肥,土壤电导率曲线波动较小,植株生长稳健,产量高。

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.
