摘    要:为改良土壤、促进蓝莓优质高产栽培和可持续发展提供参考,采用随机区组试验研究硫磺粉对栽培土壤pH和蓝莓幼苗生长的影响。结果表明:施用硫磺粉能降低土壤pH,各处理2个月内土壤pH迅速下降,较CK下降0.21~1.16,之后趋于平稳,并具有较高稳定性。施用硫磺粉最优处理蓝莓幼苗地上部分和地下部分的生长显著优于不施硫的处理(对照)。地上部分和地下部分的最适硫磺粉施用量分别为146.98g/株和166.7g/株。

关 键 词:蓝莓  有机肥  土壤改良  硫磺粉  高产栽培

Abstract:The effects of sulfur powder on soil pH and growth of blueberry seedlings was studied by the randomized block design to improve soil and provide a reference for high quality and yield cultivation of blueberry.Results:Applying sulfur powder can reduce soil pH.The pH of soil applied with sulfur powder decreases rapidly within two months and decreases by 0.21~1.16 compared with CK.The pH of soil applied with sulfur powder tends to be stable and is of the higher stability after two months.The overground and underground part of blueberry seedlings applied with the optimum sulfur powder rate is sinnificantly higher than CK.The optimum sulfur powder application rate for overground and underground of blueberry seedlings is 146.98 g/seedling and 166.7 g/seedling separately.
Keywords:blueberry  organic fertilizer  soil improvement  sulfur powder  high-yield cultivation
