摘要:

针对化肥施用过量导致农田养分流失和土壤退化等问题,探究沼液施用协同化肥减量技术在茭白田中的应用效果。试验共设置6个处理[CK,不施用任何肥料的空白对照;NPK,常规施肥(对照);25%NP1K1Z1、50%NP2K2Z2、75%NP3K3Z3、100%NP4K4Z4,沼液原液分别替代25%、50%、75%、100%的等当量氮肥],考察不同处理对茭白产量、品质,及土壤基本理化性质、土壤微生物量和土壤酶活性的影响。 结果表明: 与NPK相比,不同沼液替代处理下的茭白产量差异不显著。与NPK处理相比,75%NP3K3Z3、100%NP4K4Z4处理的茭白粗蛋白、维生素C含量显著(p<0.05)提升,硝酸盐含量显著降低,土壤有效磷、速效钾、微生物生物量碳和微生物量生物氮含量显著增加,土壤蔗糖酶、脲酶、过氧化氢酶活性显著增强。综合来看,75%NP3K3Z3在本试验条件下综合表现最好,在茭白不减产的前提下,不仅有效提升了茭白品质,还有效改良土壤,实现了茭白化肥减施增效和沼液资源化利用的目的。

Abstract:

To solve the problems of nutrient loss and soil degradation caused by excessive application of chemical fertilizer in water bamboo (Zizania latifolia) fields, the effect of biogas slurry application with chemical fertilizer reduction on water bamboo production was explored. There were six treatments in this experiment, including blank control (CK, no fertilizer was applied), control (NPK, conventional fertilization), and test treatments (biogas slurry instead of 25%, 50%, 75%, 100% equivalent nitrogen fertilizer, denoted as 25%NP1K1Z1, 50%NP2K2Z2, 75%NP3K3Z3, 100%NP4K4Z4, respectively). The effects of these treatments were monitored on water bamboo yield and quality, soil basic physical and chemical properties, soil microbial biomass and enzyme activity. It was shown that there was no significant difference in water bamboo yield among treatments excluding CK. Compared with NPK treatment, the content of crude protein and vitamin C of water bamboo was significantly (p<0.05) increased under the treatments of 75%NP3K3Z3 and 100%NP4K4Z4, while the nitrate content of water bamboo was significantly decreased. Besides, the content of soil available phosphorus, available potassium, microbial biomass carbon and microbial biomass nitrogen and the activities of soil sucrase, urease and catalase under these two treatments were also significantly higher than those under NPK treatment. In conclusion, 75%NP3K3Z3 treatment was the most suitable treatment under the test condition, as it not only improved the quality of water bamboo without yield reduction, but also improved soil properties, which achieved the goal of reducing chemical fertilizer application and increasing utilization efficiency of biogas slurry.

Key words: water bamboo (Zizania latifolia), biogas slurry, reduced chemical fertilizer application rate, soil improvement, reducing fertilizer use and increasing use efficiency
