摘要

为进一步摸清农户生产实践条件下果园土壤硝态氮分布特征及影响因素

以河北太行山山前平原的保定地区葡萄园为研究对象

调查28个果园生产管理现状

测定分析葡萄园和临近农田共31个样点0—200 cm土壤硝态氮含量、累积量及主要影响因素。结果表明:葡萄生产中氮肥施用量偏高

每季平均为297 kg/hm2

过量的养分投入导致氮素在土壤中累积

0—200 cm土层硝态氮淋洗现象明显

平均累积量高达1 555 kg/hm2。不同树龄、施氮量、灌溉量水平下

土壤硝态氮含量有所不同

但均表现出随土层深度增加而增加的趋势

并且明显高于农田土壤。相关性分析表明

硝态氮累积量与树龄和施氮量均呈极显著正相关

与灌溉量呈显著负相关。通径分析表明

对土壤硝态氮累积量影响最大的因素为施氮量

其次为树龄和施肥次数

最后为灌溉量

施肥次数主要通过影响施氮量来间接影响硝态氮累积量。研究区域葡萄园氮素盈余严重

土壤硝态氮大量累积

并向深层土壤淋洗

影响该地区硝态氮累积的主要因素为施氮量、树龄和灌溉量。

Abstract

In order to further understand the distribution characteristics and influencing factors of nitrate inorchard soil under farmers' production practice conditions

in this study

the production and management status of 28 orchards in Baoding area of Taihang Mountain piedmont plain in Hebei Province were investigated. The content

accumulation and main influencing factors of nitrate nitrogen in soil of 31vineyards and adjacent farmland from 0 to 200 cm were determined and analyzed. The results showed that the nitrogen application rate was relatively high in grape production

with an average of 297 kg/hm2 per season. Excessive nutrient input resulted in nitrogen accumulation in the soil

and nitrate leaching was obvious in 0-200 cm soil layer

with the accumulation up to 1 555 kg/hm2. Soil nitrate content varied at different tree ages

nitrogen application rates and irrigation amount

but all showed a tendency to increase with the increase of soil depth

and was significantly higher than that of farmland soil. The correlation analysis showed that the nitrate accumulation was positively correlated with the tree age and the nitrogen application rate

but negatively correlated with the irrigation amount. Path analysis showed that the nitrogen application rate was the most influential factor on soil nitrate accumulation

followed by the tree age and fertilization times

and finally the irrigation amount. The number of fertilization mainly affected nitrate accumulation indirectly through the effect of nitrogen application rate. In conclusion

the nitrogen surplus of vineyards in this region was serious

and a large amount of soil nitrate nitrogen was accumulated and leaching into the deep soil. The main factors affecting nitrate nitrogen accumulation in this region were nitrogen application rate

tree age and irrigation amount.
