研究了不同用量天然沸石斜发沸石和不同灌溉水平对马铃薯产量和品质的影响。CV. Agria，以及土耳其Konya-Karapınar缺水胁迫下土壤的养分含量。本研究采用裂区设计，重复三次。主要影响因素为沸石用量（Z 0：0、Z3：30、Z6：60、Z9：90和Z12：120 t ha−1），次影响因素为灌溉水平（I50：0.50、I75：0.75和I100：1.00）。在I100处理中，灌水至0-60 cm土层至田间持水量。在其他处理（I75-I50）中，每隔6天给予高达I100处理的75%和50%的水。灌溉用水量由冠层面积A级蒸发皿蒸发量确定。沸石用量与灌水量之间对马铃薯块茎产量、若干品质性状和土壤中某些营养元素含量的交互作用达极显著水平（P< 0.01）。在这两年中，施用Z6 I100和Z6 I75的作物产量最高，分别为33.9-39.1和33.5-34.3 kg ha−1。这两个处理之间以及其他几个处理（Z3 I100、Z9 I100和Z12 I100）之间没有显著差异。在试验年份，Z6 I75处理的耗水量分别为509和420 mm。沸石处理对供试土壤的阳离子交换量（CEC）、交换性钠离子交换量（ESP）和全P、K、Ca、Mg、Zn、Mn含量等理化指标有一定的影响。这些结果表明，一定的沸石剂量和最佳灌溉可以帮助马铃薯生长在水分胁迫条件下，因为一些土壤理化性质和作物品质的积极影响。
This study examined the effect of application of different doses of the natural zeolite clinoptilolite and different irrigation levels on yield and quality of potatoes (Solanum tuberosumL.), cv. Agria, and the nutrient contents of the soil under water-deficit stress in Konya-Karapınar, Turkey. The study was established in a split-plot design with three replications. The main factor was thezeolite dose (Z0:0, Z3:30, Z6:60, Z9:90 and Z12:120 t ha−1) and the sub factor the irrigation level (I50: 0.50, I75: 0.75 and I100:1.00). In I100treatment, irrigation was applied to fill 0–60-cm soil-depth until field capacity. In other treatments (I75-I50), it was given up to 75 and 50% of water applied to I100treatment at 6-day intervals. The amounts of irrigation water were determined by class-A pan evaporation using canopy area. For potato tuber yield, several quality characteristics and some nutrient element content in the soil, significant interaction occurred between zeolite doses and irrigation level (P< 0.01). The highest crop yields, 33.9–39.1 and 33.5–34.3 kg ha−1, respectively, were obtained from Z6I100and Z6I75applications in both years. There were no significant differences between these two treatments and also several other treatments (Z3I100, Z9I100and Z12I100). In the experimental years, water consumption of Z6I75treatment was determined as 509 and 420 mm, respectively. Some physical and chemical contents (the cation exchange capacity—CEC, exchangeable sodium percentage—ESP and total P, K, Ca, Mg, Zn and Mn contents) of the experiment soil were affected by zeolite treatments. These results showed that certain zeolite doses with optimum irrigation can be helpful for potato grown in water-deficit stress conditions because of positive effects on some soil physical and chemical properties and crop quality.
