探究复合钝化剂对原位镉(Cd)污染土壤的钝化效果及其对白菜吸收积累Cd的影响,为中轻度Cd污染农田土壤的治理修复提供科学依据。以赤泥+石灰+磷矿粉(T_(1))、赤泥+石灰+生物炭(T_(2))、石灰+腐殖酸+海泡石(T_(3))、海泡石+生物炭+赤泥(T_(4))、海泡石+生物炭+磷矿粉(T_(5))共5种复合钝化剂在原位Cd污染农田土壤中开展田间试验,研究5种复合钝化剂对耕作层土壤中各形态Cd含量、酶活性、微生物碳(MBC)、微生物氮(MBN)和白菜各部位吸收积累Cd的影响。结果表明:(1)5种复合钝化剂能不同程度提高土壤pH,降低耕作层土壤中Cd的有效性,T_(3)、T_(4)、T_(5)处理的土壤pH显著高于CK,T_(2)、T_(3)、T_(4)、T_(5)处理的土壤有效态Cd含量显著低于CK,在Cd的各个形态中,T_(5)处理的弱酸提取态Cd含量、可还原态Cd含量显著低于CK,而残渣态Cd含量显著高于CK;(2)T_(1)、T_(3)、T_(4)、T_(5)处理的土壤蔗糖酶和酸性磷酸酶活性分别比CK显著提高42.06%~152.46%、15.95%~26.48%,T_(1)、T_(2)、T_(3)、T_(4)处理的脲酶活性比CK显著提高18.43%~35.19%,T_(3)、T_(4)处理的过氧化氢酶活性比CK显著提高18.78%~19.01%,T_(1)、T_(2)、T_(3)处理的土壤MBC含量比CK显著提高31.83%~53.19%,T_(2)、T_(3)、T_(4)处理的土壤MBN含量比CK显著提高19.14%~59.89%;(3)不同处理对白菜各部位吸收积累Cd的影响有一定差异,与CK相比,T_(1)、T_(4)、T_(5)处理显著降低根部、茎部的Cd含量,5种处理均显著降低叶部的Cd含量,且白菜叶部富集、转运Cd的能力大于茎部和根部。综合钝化效果,T_(4)、T_(5)处理即海泡石+生物炭+赤泥(3∶5∶3)、海泡石+生物炭+磷矿粉(3∶5∶3)在原位钝化修复中轻度Cd污染农田土壤中的钝化效果较好,可有效降低植物对土壤重金属Cd的吸收。

A wavelength-interval switchable Brillouin–Raman random fiber laser(BRRFL) based on Brillouin pump(BP) manipulation is proposed in this paper. The proposed wavelength-interval switchable BRRFL has a full-open cavity configuration, featuring multiwavelength output with wavelength interval of double Brillouin frequency shifts. Through simultaneously injecting the BP light and its first-order stimulated Brillouin-scattered light into the cavity, the laser output exhibits a wavelength interval of single Brillouin frequency shift. The wavelength-interval switching effect can be manipulated by controlling the power of the first-order stimulated Brillouin scattering light. The experimental results show the multiwavelength output can be switched between double Brillouin frequency shift multiwavelength emission with a broad bandwidth of approximately 60 nm and single Brillouin frequency shift multiwavelength emission of 44 nm. The flexible optically controlled random fiber laser with switchable wavelength interval makes it useful for a wide range of applications and holds significant potential in the field of wavelength-division multiplexing optical communication.

在中国传统伦理思想中,行为的终极合理性由"道"所确认。孔子和孟子从实践层面解释"道",早期道家则从本体层面分析"道",他们的思想在荀子处有一合流。通过对荀子"道"论的梳理和解析,可以证明荀子之"道"实包括自然之道、本体之道、实践之道三个层面。荀子是把孔子和孟子的实践之"道"根植于道家的本体之"道"之中了。
