| In order to explore the effects of biogas slurry on the yield of water bamboo and the reasonable dosage of biogas slurry, the effects of different dosage of biogas slurry and conventional chemical fertilizer on the growth, yield and benefit of water bamboo were compared, and the differences of soil physical and chemical properties before and after planting were analyzed. The results showed that both in autumn and spring, the yield per 667 m2 of water bamboo applied biogas slurry was significantly higher than that applied with chemical fertilizer, and the growth of water bamboo was better than that applied with chemical fertilizer, but the application of biogas slurry had little effect on soil physical and chemical properties. In autumn production, the yield of water bamboo was the highest when biogas slurry fertilizer was applied for 14 t per 667 m2, and the yield per 667 m2 was 36.6% higher than that of treatment applied with chemical fertilizer. In the spring production, the yield of water bamboo with biogas slurry fertilizer for 10 t per 667 m2 was the highest, and the yield per 667 m2 of water bamboo was 58.7% higher than that applied with chemical fertilizer. The experiment proved that biogas slurry was beneficial to high yield cultivation of water bamboo. |
