摘要
采用茅草、秸秆、薄膜3种不同的材料对核桃园树盘进行覆盖处理,分析不同材料覆盖后核桃园土壤有机质、p H值和磷、氮、钾等养分含量的变化。结果表明,覆盖提高了土壤养分含量,秸杆和茅草覆盖对土壤养分提高效果较为明显。
Thatch, straw and thin film, 3 kinds of different materials were used to cover the walnut trees, and the changes of soil nutrients including soil organic matter, pH, phosphorus, nitrogen, kalium were analyzed. The results showed that the content of soil nutrients were improved by using coverage and soil nutrients increased obviously coved by straw and thatch.
