摘要:

通过探讨餐厨废弃物土壤调理剂对改良土壤质量、促进作物生长的综合效果,旨在为水稻高产稳产提供技术支撑。采用田间试验,比较不同施用量对土壤理化性状和水稻产量的影响。结果表明:施用餐厨废弃物土壤调理剂能有效改善土壤pH,显著增加土壤有机质、全氮、有效磷等养分含量,具有较好地提升土壤肥力的作用。但土壤水溶性盐含量整体随调理剂用量的增加呈上升趋势,存在盐分积累的风险。此外,由于该调理剂氮含量较高,施用量过高使水稻生长存在贪青晚熟、倒伏较严重等情况,导致产量下降。综合分析土壤改良、盐分积累和水稻增产,T3和T4处理效果较好。

Abstract:

By studying the comprehensive application effects of food waste soil conditioners on soil quality and crop growth, we aim to provide technical support for high and stable yield of rice. Different application rates on improving soil physicochemical properties and rice yield were discussed by plot field experiments. The results showed that food waste soil conditioners could effectively improve soil pH, and significantly increase the contents of soil organic matter, total nitrogen and available phosphorus. However, the soil total water-soluble salt content showed an upward trend with the increase of the conditioner application rate, so there was a risk of salinity accumulation. In addition, due to the high nitrogen content of the conditioner, high application rate could cause rice over-green and lodging, resulting in yield reduction. Comprehensive analysis of soil improvement, salinity accumulation and rice yield, T3 (conditioner rate of 15000 kg/hm2 + fertilizer) and T4 (conditioner rate of 30000 kg/hm2 + fertilizer) had better effects.
