木本泥炭新型肥料在砖红壤甘蔗上的应用

摘要

The growth, agronomic characters, cane yield and sugar yield of planted cane (YT03-393), and soil fertility was studied in lotosol soil with the blank control; the recommended fertilization and recommended fertilization add 5 different woody peat fertilizers respectively. The results showed that woody peat biological fertilizer treatment significantly increased millable canes, compared with the recommended fertilization. Cane yield and sugar yield for all 5 woody peat fertilizer treatments were significantly higher than that of the recommended fertilization. Also the content of total nitrogen, total phosphorous, available phosphorous, total potassium and organic matter in soil were improved. Finally the economic benefits with woody peat fertilizers were higher than that of the recommended fertilization.%在粤西砖红壤上以粤糖03-393为供试品种，通过设置空白对照、常规推荐用肥、常规推荐用肥与分别添加5种木本泥炭肥料配施共7个处理的田间试验，研究了木本泥炭新型肥料对新植甘蔗农艺性状、蔗茎产量、理论产糖量及土壤肥力的影响。结果表明：与仅施常规推荐用肥相比，施用木本泥炭生物有机肥处理能显著增加甘蔗有效茎数。5个增施木本泥炭肥料处理的蔗茎产量和理论产糖量均比仅施推荐用肥处理显著增加，土壤中全氮、全磷、速效磷、全钾和有机质的含量也显著提高，经济效益相应得到增加。
