施用不同比例氮磷钾肥对暖地型草坪冬季质量的影响

The Effects of N,P,K Fertilizers on the Quality of Warm-season Turfgrasses in Winter

将氮、磷、钾肥按6种不同的比例混合配置,施用在暖地型草坪台湾草和假俭草上,以观测氮、磷、钾不同比例对暖地型草坪冬季质量的影响。结果表明在本试验设计的范围内当N∶P∶K=4∶1∶2时,草坪冬季质量效果最佳。

Effects of N,P and K fertilizer with different application proportionof on the quality of warmseason turfgrasses were studied in winter, 2000. Total 6 treatments were applied to Zoysia tenuifolia and Eremochloa ophiuroides. The results shown that the turf quality was significantly improved in winter under the proportion of 4∶1∶2 (N∶P2O5∶K2O) .
