摘要:

针对藕塘肥料使用潜在的面源污染,开展莲藕绿色高效生产功能肥筛选和肥料定额制研究。结果表明,对于藕塘土壤来说,总养分保持在795 kg·hm-2并施用炭基肥的处理对于藕塘土壤pH值、有机碳和全氮含量有显著提高,对于全磷和全钾含量并未产生显著影响。对藕塘田面水来说,除总磷含量外,田面水的各项理化指标随着生长周期的延长而显著降低,在幼苗期时各项理化指标数值最高。在20%炭基有机肥替代常规施肥的处理中,结藕根数、莲藕总产量和单根藕质量均显著增加,增幅分别为20.2%、31.2%和9.16%。总的来看,莲藕的施肥最高限量值设置为氮磷钾总养分795 kg·hm-2、纯氮375 kg·hm-2是科学合理且较为可行的,完全能够满足莲藕绿色高效生产的需要。

Abstract:

In view of the potential non-point source pollution of lotus pond fertilizer, the screening of green and efficient lotus root functional fertilizer and fertilizer quota system were studied. The results showed that the soil pH value, organic carbon and total nitrogen content of the soil were significantly increased when the total nutrient was kept at 795 kg·hm-2 and carbon-based fertilizer was applied, but the total phosphorus and total potassium were not significantly increased. In addition to total phosphorus, the physicochemical indexes of surface water decreased significantly with the extension of growth cycle, and the values of physicochemical indexes were the highest at seedling stage. In the treatment of replacing conventional fertilization with 20% carbon-based organic fertilizer, the number of roots, total output of lotus root and weight of single root were significantly increased by 20.2%, 31.2% and 9.16%, respectively. In general, the maximum fertilization limit of lotus root is set as 795 kg·hm-2 of total nitrogen, phosphorus and potassium and 375 kg·hm-2 of pure nitrogen, which is scientific, reasonable and feasible, and can fully meet the needs of green and efficient production of lotus root.
