摘要:

为探究不同土壤管理方式对桃园土壤理化性质的影响,以河南省信阳市桃园为试验对象,设置地膜覆盖(覆盖黑色可降解膜)和自然生草2个处理,以清耕为对照,分析不同处理对土壤有机质、pH值、氮磷钾含量和水热的影响。结果表明: 与清耕对照相比,地膜覆盖和自然生草处理均能显著(P<0.05)提高0~10 cm土层的有机质含量,但对土壤pH值无显著影响;自然生草处理下,0~10 cm土层的全氮含量显著升高24.39%,10~20 cm土层的有效磷含量显著升高27.11%,0~10、10~20 cm土层的速效钾含量亦显著升高;地膜覆盖处理下,0~10、10~20 cm土层的碱解氮含量分别显著升高18.51%、20.49%。各处理对20~40 cm土层养分含量无显著影响。自然生草处理在7~9月增加了土壤含水量,增强了土壤温度的稳定性;地膜覆盖处理在前期增加了土壤含水量,对土壤具有一定的增温作用。

Abstract:

In order to investigate the impact of different soil management techniques on the physical and chemical characteristics of soil in the peach orchard, a filed experiment was conducted in Xinyang City, Henan Province, with two treatments of plastic film mulching (black degradable film mulching) and natural grass growing, while the clean cultivation was served as the control (CK). The changes of soil pH, temperature and the contents of organic matter, nitrogen, phosphorus, potassium, and water were analyzed. The results indicated that, in comparison to the CK, the plastic film mulching and natural grass growing treatments both significantly (P<0.05) increased the soil organic matter content in the 0-10 cm soil layer, yet had no significant impact on soil pH. The natural grass growing treatment significantly increased the total nitrogen content in the 0-10 cm soil layer by 24.39%, and the available phosphorus content in the 10-20 cm soil layer by 27.11% compared with the CK. Besides, the natural grass growing treatment also significantly increased the available potassium content in the 0-10 and 10-20 cm soil layer than that of the CK. The plastic film mulching treatment significantly increased the available nitrogen content in the 0-10 and 10-20 cm soil layer by 18.51%, 20.49%, respectively. The two treatments of plastic film mulching and natural grass growing exhibited no significant influence on the nutrients content in the 20-40 cm soil layer. The natural grass growing treatment increased soil water content from July to September and enhanced the soil temperature stability. The plastic film mulching treatment resulted in an increase in soil water content during the initial stages and showed positive effect on soil warming.
