农业科学施肥工作是小麦种植过程中需要把握的关键环节,种植者在进行小麦种植过程中需要有效提高施肥工作的重要性认识,结合小麦种植区域的自然环境因素以及小麦品种特点的具体情况,采取合理化的施肥技术,更好地让施肥工作满足小麦生长发育的必要需求。但是,在目前的小麦种植过程中,由于部分种植人员缺乏对施肥技术的系统化认识,这在一定程度上阻碍了科学的施肥技术在小麦种植具体过程中的落实,严重影响了小麦种植整体质量地提升。因此,本文将充分分析小麦种植过程中的施肥技术,从而更好地优化施肥方法,促进小麦种植的质量和产量提升 ...

农业科学, 2019 常规施肥方式容易造成前期旺长、后期植株脱肥的情况,本试验对氮、钾肥采取“前控、中促、后补”施肥技术,在施肥总量相同的情况下,通过拔节期追施氮、钾肥及大喇叭口期叶面追肥,为玉米穗、粒期持续提供所需养分,从而达到增产的目的,筛选出适宜的施肥方法为深施普通尿素30%+缓释尿素30%、深施70%硫酸钾+拔节期追施30%硫酸钾、拔节期+大喇叭口期叶面追肥磷酸二氢钾1.5公斤/公顷。

Shuitu Baochi Xuebao, 2020 通过构建包括不同氮肥类型、氮肥用量、施肥方式和施肥次数的6种氮肥运筹模式，分析了不同氮肥运筹模式对稻田田面水各形态氮浓度变化和水稻产量的影响。结果表明：不同时期施用缓控释肥和尿素后，总氮和铵态氮浓度均在1天达到峰值，硝态氮浓度在2~3天达到峰值，之后逐渐下降趋于稳定。铵态氮为各处理施肥后初期的主要氮形态，1天时铵态氮占总氮比例达50.6%~92.8%，而硝态氮仅占3.8%~22.6%。田面水总氮和铵态氮峰值浓度大小与氮肥类型、施用用量和施肥方式均存在相关性，等氮量施用条件下 ...

Integrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

Abstract Tropical forests are generally characterized by high species diversity and low soil phosphorus (P) availability. Although tropical plants have evolved adaptations to low soil P availability, we know relatively little about the strategies of different groups of species ...
