沸石(Z)已被广泛应用于水稻增产，但在沸石改良的干湿交替灌溉(AWD)条件下，氮素(N)的积累和运转对水稻产量的影响尚缺乏相关信息。通过设置蒸渗仪的田间试验，研究了两种灌溉方式(连续淹水灌溉)下，施氮量(0、5和10tZ ha−1)对水稻产量、分蘖数、叶面积指数(LAI)、干物质积累和运转(DMA和DMT)、N积累和运转(NA和NT)和土壤无机氮含量的影响。结果表明，旱作对2016年水稻产量没有影响，但在2017年不施Z的情况下降低了产量，两年内施10 t Z ha−1对水稻产量没有影响。AWD降低了2016年的最高分蘖数和无效分蘖数，2017年的最高分蘖数和最终分蘖数，以及联合孕穗期后的LAI。Z修饰剂显著增加了最高分蘖数和最终分蘖数，但对无效分蘖数无显著影响，提高了孕穗期后的叶面积指数。主成分分析表明，抽穗后产量与单位面积穗数、单位面积净穗数、地上单位面积单位面积和单位面积单位面积净增单位面积数之间的相关关系更为显著。与对照相比，AWD在两年的穗分化期后显著降低了地上部分的DMA，在两年的联合孕穗期后显著降低了地上部分的NA，在2016年显著降低了地上部的DMA，但在2017年没有显著的降低。Z改良剂显著提高了分蘖期后的地上部DMA和NA，以及每平方米的净光合速率和穗数。此外，添加Z改良剂的AWD显著提高了土壤无机氮含量。
Zeolite (Z) has been widely used for improving rice production, but there is a lack of information on how nitrogen (N) accumulation and translocation affect yield performance of paddy field in the alternate wetting and drying irrigation (AWD) amended with zeolite. In this study, a 2-year field experiment with installed lysimeters was carried out to determine the influence of Z application (0, 5 and 10 t Z ha−1) on rice yield, tiller number, leaf area index (LAI), dry matter accumulation and translocation (DMA and DMT), N accumulation and translocation (NA and NT), inorganic N content in soil under two irrigation regimes (CF: continuously flooded irrigation, AWD). The results showed that AWD didn’t affect rice grain yield in 2016, but reduced it in 2017 without Z application; and rice yield was not affected by AWD with the application of 10 t Z ha−1in two years, relative to CF. AWD reduced highest and ineffective tiller number in 2016, and highest and final tiller number in 2017; as well as LAI after joint-booting stage, relative to CF. Z amendment significantly increased highest and final tiller number, but didn’t affect ineffective tiller number; and increased LAI after joint-booting stage. The principal components analysis showed that grain yield was more significantly correlated with the panicles per m2, NT, and aboveground DMA and NA after panicle-initiation stage. As compared to CF, AWD significantly reduced aboveground DMA after panicle-initiation stage; aboveground NA after joint-booting stage in both years; and NT in 2016, but not in 2017. Z amendment significantly improved aboveground DMA and NA after tillering stage, as well as NT and panicles per m2. In addition, AWD with Z amendment significantly improved inorganic N content in soil.
