摘要:

为明确鄂西南山区植烟土壤养分时空变化特征,优化烟叶种植布局和落实平衡施肥,分别于2018和2021年采集建始县10个乡镇共计578个植烟土壤进行分析。结果表明:2021年建始县植烟土壤pH值、有机质、全氮含量分别比2018年降低0.55、6.06 g·kg-1、0.47 g·kg-1,速效磷和速效钾含量分别比2018年升高9.91、37.62 mg·kg-1。2021年全县土壤综合肥力指数平均值为0.72,较2018年增加。综合以上发现,需要通过增施有机肥和调整钾肥施用方式,改善建始县植烟土壤肥力状况,提高土壤钾肥利用率以及有机质和全氮含量。

Abstract:

To clarify the spatiotemporal variation characteristics of soil nutrients in tobacco-growing soils in the mountainous areas of southwestern Hubei and optimize tobacco-growing layouts and balanced fertilization practices, 578 tobacco-growing soil samples from 10 townships in Jianshi County were collected and analyzed in 2018 and 2021. The results indicated that, compared with 2018, the soil pH value, organic matter, and total nitrogen content in 2021 decreased by 0.55, 6.06 g·kg-1, and 0.47 g·kg-1, respectively, while the available phosphorus and available potassium content increased by 9.91 and 37.62 mg·kg-1, respectively. The average integrated fertility index in 2021 was 0.72, showing an increase compared with 2018. Based on these findings, measures such as increasing organic fertilizer application and adjusting potassium fertilization methods are recommended to improve soil fertility, enhance potassium utilization efficiency, and increase organic matter and total nitrogen content in Jianshi County's tobacco-growing soils.
