摘要:

本试验通过不同施肥处理,探究其对茭白产量及根际环境的影响。 结果表明,施用原起微生物菌剂(YQ2处理)的效果最佳,茭白667 m2产量为935.63 kg,较常规施肥(NPK处理)增产24.2%。多种微生物肥的施用,对茭白养分吸收、土壤理化性质和田面水全氮浓度均产生不同程度的影响。茭白养分含量呈现“肉质茎中最高、茎叶次之,根系最低”的规律。施肥虽对养分吸收具有一定影响,但无明显规律性。随着茭白生育期推迟,土壤pH值和有机质含量升高,土壤有效磷、速效钾、铵态氮和硝态氮含量降低。施肥会迅速提高田面水全氮浓度,施用森井复合微生物菌肥(SJ)处理在降低全氮浓度方面表现最优。

Abstract:

This experiment investigated the effects of different fertilization treatments on the yield of Zizania latifolia Turcz. and its rhizosphere environment. The results showed that the application of Yuanqi microbial agent (YQ2 treatment) achieved the best effect, with a yield of 935.63 kg per 667 m2, representing 24.2% higher than that of conventional fertilization (NPK treatment). The application of various microbial fertilizers had varying effects on nutrient uptake in Zizania latifolia Turcz., soil physical and chemical properties, and total nitrogen concentration in field surface water. Nutrient contents in Zizania latifolia Turcz. followed the pattern of “the highest in fleshy stem, followed by stems and leaves, and the lowest in the roots.” Although fertilization had a certain effect on nutrient uptake, there was no obvious regularity. As the growth period of Zizania latifolia Turcz. was delayed, soil pH value and organic matter content increased, while available phosphorus, available potassium, ammonium nitrogen, and nitrate nitrogen contents in the soil decreased. Fertilization rapidly increased the total nitrogen concentration of field surface water, while application of Senjing compound microbial agent (SJ treatment) had the highest efficiency in reducing it.
