- 摘要:
- 为分析不同年限沙棘人工林的土壤养分和酶活性的时空变化规律,采用时空互代法,以志丹县金丁镇不同种植年限沙棘人工林(20年生沙棘林、15年生沙棘林、5年生沙棘林)为研究对象,以谷子地作为对照,研究了土壤养分和酶活性季节变化、空间分布及其相关关系。结果表明:随着种植年限的增加,沙棘人工林显著地增加了土壤有机质、碱解氮、有效磷、有效钾和酶活性。土壤养分和酶活性具有表聚性,随着土层加深含量在下降且土层间差异显著。沙棘人工林和谷子地土壤养分和酶活性均有明显的季节变化特征。0—30 cm土层土壤有机质表现为春季和秋季较高,夏季和冬季较低。碱解氮和有效磷均为春季最高,秋季最低,而有效钾为冬季最高,夏季最低。土壤脲酶季节变化规律为春夏较高,秋冬季较低。蔗糖酶活性春冬季较高,夏秋季较低。过氧化氢酶呈现出与脲酶和蔗糖酶不同的响应特征。土壤养分与土壤酶相关性密切,土壤脲酶和蔗糖酶可以作为评价土壤肥力的指标。综上,在陕北黄土丘陵区,营造沙棘林年限越长,提高土壤养分和酶活性效果越明显。
- Abstract:
- In order to investigate the spatial distribution characteristics of soil nutrients and enzyme activities in Hippophae rhamnoides plantation with different stand ages in loess hilly region, based on the method of spatiotemporal interaction, three different stand ages of Hippophae rhamnoides plantation, such as 5-year-old, 15-year-old and 20-year-old were selected in Jinding Town of Zhidan County. The farmland was selected as the control. Soil samples were collected in 0—10 cm, 10—20 cm and 20—30 cm soil layers. The results showed that the measures of returning farmland to forest significantly increased the soil nutrients and enzyme activities, especially in the 0—10 cm soil layer; there were significant differences in the above indexes among different soil layers and between different stand ages of Hippophae rhamnoides plantation and farmland; soil organic matter contents in spring and autumn were higher than those in summer and winter; alkaline hydrolysis nitrogen and available phosphorus in spring were the highest and lowest in autumn; available potassium was highest in winter and lowest in summer. Urease activity were higher in spring and summer than that in autumn and winter. Sucrase activity was higher in spring and winter than that in summer and autumn; catalase showed an inverted change trend with seasonal changes; correlation analysis showed that soil nutrients had a positive correlation with urease activity and sucrase activity. To sum up, Hippophae rhamnoides plantation is a suitable afforestation model, which can help improve soil nutrient and enzyme activities.
