Development of environment-friendly sustainable rice farming with reuse of new purification plant sludge、 and application of iron or silicon

在有机稻作系统中，应用来自净水厂的聚硅酸铁(PSI)污泥、未利用的废弃物、提高稻米产量和糙米品质、减少因喂米臭虫造成的籽粒损伤。施用PSI污泥和硅酸盐能有效提高水稻根系伸长和活力。PSI污泥具有降低有机水稻土甲烷排放的潜力。PSI污泥和硅酸盐肥料的应用有助于建立环境友好型水稻农业技术。

Application of poly-silicate iron (PSI) sludge derived from water purification plants, unused waste, improved rice yields and brown rice quality, and decreased pecky rice damage caused by rice-feeding bugs in the organic rice farming system. PSI sludge and silicate application were effective in increasing rice root elongation and activity. PSI sludge showed the potential of decreasing methane emission in the organic-applied paddy soils. Application of PSI sludge and silicate fertilizer can contribute to establish the technology of environment-friendly paddy agriculture.
