Effects of Mulching on Soil Nutrients of Moso Bamboo Plantation
-
摘要: 笔者对连续3 a进行覆盖生产早出笋的毛竹林地土壤养分进行了研究。研究结果表明:实施覆盖后毛竹林地土壤全氮、全磷、全钾、有效氮及有效磷含量呈现出先升后降(第1、2年上升、第3年下降),有效钾含量持续上升,有机质及矿质元素含量持续下降。氮、磷元素有效态与全含量间呈显著正相关性。有机质氮磷钾元素含量间存在不同程度的相关性,与有效钾含量呈极显著正相关性,与全磷、有效磷含量呈显著负相关性,与氮元素及全钾含量之间呈不显著的负相关性。Abstract: Soil nutrients of Moso bamboo plantation with mulching for 3 consecutive years were analyzed. The results showed that the contents of soil total nitrogen, total phosphorus, total potassium, available nitrogen and available phosphorus increased in 1st and 2nd years and then decreased in 3rd year. The content of available potassium increased continuously, while the contents of organic matter and mineral elements decreased continuously. There was a strong positive correlation between the contents of available nitrogen and phosphorus and the contents of total nitrogen and phosphorus. There were various degrees of correlation between the content of organic matter and those of nitrogen, phosphorus and potassium. The content of organic matter had a significant positive correlation to the content of available potassium, a significant negative correlation to those of total phosphorus and available phosphorus, and a weak negative correlation to the contents of nitrogen and total potassium.
