| Popis: | Uptake of nitrogen (N), phosphorus (P), and potassium (K) by Mat Rush (Juncus effusus L. var. Decipiens Bchen) (cv. Gangshan 3) and the effects of N and K fertilizers on yield and quality of paddy field‐grown Mat Rush were studied. The results showed that plant tissue N and K concentrations gradually declined with plant growth, ranging from the maximum of 3.32% and 3.48% to the minimum of 1.66% and 1.79%, respectively. Plant tissue P concentration declined slightly during early growth, then increased in effective‐stem tillering stage. Highest P concentration was 0.36%. Maximum accumulations of N, P, and K in foliage were N 293.9 kg ha−1, P2O5 59.7 kg ha−1, and K2O 374.5 kg ha−1, respectively. In comparison with the control, N fertilizer significantly increased stems per hill (SPH), average stem length (ASL), long stem percentage (LSP), and stem chlorophyll content (SCC), beneficial to stem quality improvement, leading to significantly increased yield, and meanwhile caused higher stem flowering ra... |
