施肥对杂交结缕草成坪期土壤养分的影响

Effect of Fertilizer on Soil Nutrition in Hybrid Zoysia Turf During Forming Turf

通过杂交结缕草田间肥效试验,观测了不同施肥处理对土壤养分的影响。其结果表明,草坪成坪后,土壤 的全氮、有机质和pH值基本不变,而土壤的速效氮、速效磷含量升高,3、4水平的增加量大于1、2水平;速效钾含量降 低,1、2水平的降低量大于3、4水平。

The effect of fertilizer of different level on soil nutrient of Hybrid strain of Zoysia japonica and Z.tenuifolia was determined in this test.The preliminary results showed that during forming turf, the total N, organic compound and pH value in soil did basically not change, but the content of quickly soluble N and P increased, and the increment of 3, 4 level was higher than that of 1, 2 level. While the content of quickly soluble K decreased, and the fall of 1, 2 level was higher than that of 3, 4 level.
