Abstract

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.

Key words: Zizania latifolia Turcz., microbial fertilizer, plant nutrition, rhizosphere soil, rhizosphere water
