    摘要:

    明确中国花生产区土壤养分状况,对指导花生科学施肥、促进花生高产高效生产至关重要。于2022年在中国花生主产区采集1 020个耕层土壤样品,评价了中国花生种植土壤有机质、全氮、碱解氮、有效磷、速效钾及pH状况,分析了不同起垄种植方式、产量水平、土壤类型及土壤质地下花生种植土壤养分的变化特征。结果表明,中国花生主产区土壤有机质、全氮、碱解氮含量平均分别为15.15 g·kg-1、1.01 g·kg-1、104.49 mg·kg-1,分别有78.62%、60.49%和43.72%的样点处于缺乏水平,且主要集中在东北、西北和黄淮海花生产区的辽宁、河北、河南、新疆等地。土壤有效磷含量平均为39.76 mg·kg-1,仅有13.14%的样点缺磷,且主要分布在南方区的云南和长江流域花生产区的四川等地。土壤速效钾含量平均为126.71 mg·kg-1,有38.62%的样点缺钾,主要分布在黄淮海的河北和南方花生产区的广东等地。耕作方式、种植方式、产量水平影响土壤养分状况,起垄种植的土壤碱解氮和速效钾含量分别较平作显著提高6.04%和31.72%;夏播花生土壤有机质、碱解氮、速效钾和全氮含量较春播和麦套花生分别平均提高24.33%、67.37%、25.85%和14.87%;高产地块土壤pH、碱解氮、有效磷含量较低产地块分别提高5.48%、6.33%和26.24%。不同土壤类型的土壤养分特征也存在差异,各土类土壤有机质含量(16.08 g·kg-1)整体偏低,以风沙土(11.5 g·kg-1)最低;风沙土(79.2 mg·kg-1)、褐土(75.33 mg·kg-1)、灰钙土(84.29 mg·kg-1)和潮土(84.88 mg·kg-1)的土壤碱解氮含量缺乏;各土类土壤有效磷含量(39.43 mg·kg-1)较为丰富,以砂姜黑土(70.31 mg·kg-1)最高;砖红壤的土壤速效钾含量(78.78 mg·kg-1)缺乏。整体而言,中国不同花生产区土壤养分存在较大差异,土壤有机质、全氮、碱解氮不足主要出现在东北、西北和黄淮海风沙土、潮土和褐土花生产区,土壤有效磷基本不缺,土壤速效钾不足主要出现在南方砖红壤花生产区。建议中国花生主产区应严格控制磷肥投入,在土壤氮、钾缺乏的花生产区适量增施氮肥和钾肥。

    Abstract:

    【Objective】 Clarifying the soil nutrient status of peanut production regions in China is crucial for guiding the scientific fertilization practices in peanut cultivation and promoting high yield and high nutrient use efficiency. 【Method】 In 2022, 1 020 soil samples were collected from major peanut production regions in China, and the soil organic matter (SOM), total nitrogen (TN), available N(AN), available phosphorus (AP), available potassium (AK) and pH status were evaluated. The variation characteristics of soil nutrients in peanut planting soils were also analyzed by different ridge planting methods, yield levels, soil types and soil textures. 【Result】 The results showed that the average SOM, TN and AN contents in the peanut-producing regions were 15.15 g·kg-1, 1.01 g·kg-1 and 104.49 mg·kg-1, respectively. Also, 78.62%, 60.49% and 43.72% of the sampling points for SOM, TN and AN were deficient, mainly concentrated in the Northeast, Northwest, and Huang-Huai-Hai peanut production regions, such as Liaoning, Hebei, Henan, and Xinjiang provinces. The average soil AP content was 39.76 mg·kg-1, with only 13.14% of the sample points in the P deficiency level, mainly distributed in the south and the Yangtze River basin, in areas such as Sichuan and Yunnan provinces. The average soil AK content was 126.71 mg·kg-1 and 38.62% of the sample points were deficient in K and mainly distributed in Hebei and Guangdong province in the Huang-Huai-Hai and southern peanut production regions. In addition, the soil nutrient status was affected by the tillage practices, planting modes, and yield levels, with the soil AN and AP contents in ridge cropping significantly increased by 6.04% and 31.72% compared with those of flat cropping. The result also revealed that SOM, AN, AP, and TN contents in summer peanut were significantly increased by 24.33%, 67.37%, 25.85%, and 14.87% (respectively) compared with those of spring peanut and intercropped peanuts with wheat. The soil pH, AN, and AP contents of high-yield plots were respectively increased by 5.48%, 6.33%, and 26.24% compared with those of low-yield plots. There were also differences in soil nutrient characteristics among different soil types. For instance the SOM content(16.08 g·kg-1) of all soil types was generally low, with the lowest in the wind-sand soil (11.5 g·kg-1) while the soil AN content of the wind-sand soil (79.2 mg·kg-1), brown soil (75.33 mg·kg-1), grey calcareous soil (84.29 mg·kg-1), and tidal soil (84.88 mg·kg-1) was deficient. The AP content(39.43 mg·kg-1) of all soil types was relatively abundant and highest in the lime concretion black soil (70.31 mg·kg-1) whereas AK content was deficient in the latosols (78.78 mg·kg-1). 【Conclusion】 There are significant differences in soil nutrients in different peanut-producing regions in China. The deficiencies of SOM, TN, and AN mainly occurred in wind-sand soil, tidal soil and brown soil in the northeast, northwest China, and Huang-Huai-Hai peanut production regions. Also deficiencies in AK mainly occurred in the peanut areas of southern brick-red soil. It was recommend strict control of the input of P fertilizer and increase the application of N and K fertilizers in soils with N and K deficiencies in peanut production regions of China.
