采用GPS定位取样测试、ACIGIS软件数据分析和地统计分析方法,对凉州区日光温室土壤养分状况进行了分析评价。结果表明,在0~20 cm表层土壤中,不同种植模式的氮、磷、钾养分分布趋势基本一致。种植番茄—架豆、番茄—辣椒电导率最大,为1.97 ms/cm;种植番茄—架豆盐分最高,为11.9 g/kg;种植人参果CEC最大,为16.87%。在20~40 cm土壤中,种植番茄—辣椒电导率最高,为2.59 ms/cm;种植小乳瓜盐分最大,其值为17.9 g/kg;种植人参果CEC最大,为19.94%。
Using GPS positioning and sampling test, ACIGIS software data analysis and geostatistical analysis method, the status of soil nutrients in sunlight greenhouse in Liangzhou was analyzed and evaluated. The results showed that in 0-20 cm topsoil, the distribution of N, P and K nutrients in different planting patterns was basically the same. The highest conductivity was 1.97 ms / cm for planting tomato-shelf bean and tomato-peppers. The highest salt-growing tomato-shelf bean was 11.9 g / kg and the highest CEC for planting ginseng was 16.87%. In 20 ~ 40 cm soil, the conductivity of tomato-peppers was the highest, which was 2.59 ms / cm. The seedling had the highest salinity of 17.9 g / kg and the highest CEC of planting ginseng was 19.94%.
