施用黑炭和羊粪对库尔勒香梨园土壤理化性质与产量的影响

Influences of Applying Black Carbon and Sheep Excrement on Soil Properties and Yield of Korla Fragrant Pear Orchard

为了解黑炭和羊粪在库尔勒香梨生产中的应用效果,采用化肥配施黑炭和羊粪的田间调控试验,研究黑炭和羊粪对库尔勒香梨园土壤理化性质和产量的影响。结果表明:与不施黑炭和羊粪的CK处理相比,施用黑炭和羊粪能有效改变果园土壤颗粒组成,改善土壤物理性质,提高土壤有机质及速效养分含量,促进果园增产。施用黑炭、羊粪27 000 kg·hm-2的处理效果较为显著,其中施用黑炭27 000 kg·hm-2对提高土壤有机质含量和改善土壤物理性质效果更显著;施用羊粪27 000 kg·hm-2对提高土壤碱解氮、有效磷和速效钾的含量以及香梨产量效果更显著。

In order to master the application effects of black carbon and sheep excrement in production of Korla fragrant pear, the regulatory trials were carried out by applying chemical fertilizers with black carbon and sheep excrement in field, to study the effects on soil properties and yield of Korla fragrant pear orchard. The results showed that compared with the treatment with non-applying black carbon and sheep ex- crement （CK）, applying black carbon and sheep excrement could effectively change the composition of soil particles, improve soil physical properties, increase contents of soil organic matter and available nutrients, and promote production of orchard. The effect of treatment with applying 27 000 kg·hm-2 black carbon and sheep excrement was more remarkable, the treatment with applying 27 000 kg·hm-2 black carbon was more significant to increase contents of soil organic matter and improve soil physical properties, while the treatment with applying 27 000 kg·hm-2 sheep excrement was more significant to increase contents of soil alkaline hydrolysis N, available phosphorus, available potassium and yield of Korla fragrant pear.
