摘要： 通过开展酸性硫酸盐土壤下不同土壤改良措施及不同施肥措施配合试验,研究了不同轻简化施肥技术对水稻生长的影响。结果表明,酸性硫酸盐土壤早稻以施用改良剂及钙镁磷肥的酸性改良效果最佳,平均增产率6.4%-6.7%,晚稻则以施用有机肥的酸性改良效果最佳,平均增产5.4%。采用一次性施肥的缓/控释肥处理基础养分供应较充分,可以促使水稻早发快发分蘖,并保持对水稻的持续养分供应。早稻缓释肥产量最高,较常规施肥平均增产4.1%,晚稻控释BB肥处理产量最高,较常规施肥平均增产4.2%。最优轻简化施肥技术为一次性施用高磷缓释肥配施有机肥。

Abstract: To clarify the effect of simplified fertilization on the rice growth, field experiments of different soil improvement and fertilization measures were conducted on acid sulphate soil (ASS). The results showed that applying soil conditioner (SC) and calcium magnesium phosphate (CMP) had the best effect on early rice growth, the average increase rate was 6.4%-6.7%. In contrast, microbial organic fertilizer (MOF) had the best effect on late rice growth, the average increase rate was 5.4%. The basic nutrient application of slow/controlled release fertilizer with single basal fertilization was sufficient for rice, which could promote the early tillering and maintain the continuous nutrient supply. Compared with the normal fertilization, the slow-release fertilizer (SRF) applied on early rice could increase rice yield by 4.1%, the controlled-release bulk blending fertilizer (CRF) applied on late rice could increase the yield by 4.2% . In sum, the optimal simplified fertilization technology for rice in acid sulphate soil is single basal application of slow- release fertilizer with high phosphorus and organic fertilizer.
