对五峰高山天葱生境土壤中的N、P、K含量的空间分布进行了初步研究。试验采用野外调查与室内分析的方法,于天葱长势旺盛的大葱园,找A、B、C3处具有代表性的样地,采用相邻格子法做1m×1m样方,每块样地取16份土样,进行室内N、P、K含量的分析。采用传统统计学和地统计学相结合的方法对所取的数据进行分析,利用GS软件的空间分析功能,绘制了表达这些样地土壤中N、P、K含量的随机性和结构性的半方差图和空间分布图。研究结果表明:样地速效N、速效P、速效K含量具有很弱的空间相关性;土壤N、P、K含量的相关距变化范围为2.19～6.88m。该结果可为天葱的其他研究及人工种植田的定位施肥和精细管理提供一定的科学依据。
The spatial distribution of N, P and K contents in soils of Onion in Wufeng alpine was studied. The field survey and indoor analysis methods were used in the experiment. In the green onion garden where the onion is growing vigorously, the representative sample plots A, B and C3 are taken and the adjacent grid method is used to make 1m × 1m quadrats. 16 soil samples for indoor N, P, K content analysis. By using the method of traditional statistics and geostatistics, the data collected were analyzed and the spatial and temporal analysis of GS software was used to draw the stochastic and structural half of N, P, K contents in soils Variance and Spatial Distribution. The results showed that the available N, available P and available K contents in the plot had a very weak spatial correlation. The correlation range of N, P and K in the soil ranged from 2.19 to 6.88 m. The results can provide some scientific basis for other research and artificial fertilization field management and fertilization and fine management.
