人们已经广泛研究了沸石对不同旱地作物的生长和产量的影响，但关于沸石对水分胁迫下低地水稻生长的影响的研究很少。利用蒸渗仪在大田条件下研究了3种灌溉方式(CF、IAWD、AWD)下沸石施用量(15tha-1)对沈农9765水稻物候、产量和品质的影响。除分蘖、拔节孕穗期和抽穗开花期的SPAD值、抽穗开花期的净光合速率(Pn)、籽粒产量和水分利用效率(WUE)外，在不同水分供应条件下，沸石的施用量均显著增加水稻的叶面积指数(LAI)和SPAD值。添加沸石显著提高了整精米率，降低了垩白率和垩白度。IAWD和CF处理抽穗开花期的SPAD值和Pn和籽粒产量相似，而AWD处理显著降低了这些值。IAWD和AWD处理显著提高了WUE、精米率、整精米率、峰值粘度和崩解率，但降低了水分利用效率、LAI、垩白米率、垩白度、冷粘度和消减率。这些结果表明，在水稻上采用IAWD+15tha-1沸石施用量，可以减少灌溉用水量，提高产量，改善稻米品质。
Plant growth and grain yield of various upland crops in response to zeolite application have been extensively studied, but little information is available on the impact of zeolite application on rice grown in the lowlands under water stress. A two-year experiment was conducted using lysimeters in the field to evaluate the influence of zeolite application (15 t ha–1) on phenology, grain yield and grain quality in a local rice cultivar (Shennong 9765) under three irrigation regimes (CF, continuous flooding irrigation; IAWD, improved alternate wetting and drying irrigation; and AWD, alternate wetting and drying irrigation). Regardless of water supply, zeolite application significantly increased leaf area index (LAI) at all the measured stages except for tillering, SPAD values at the jointing–booting and heading–flowering stages, photosynthetic rate (Pn) at heading–flowering stage, and grain yield and water use efficiency (WUE). Moreover, zeolite addition significantly increased the head rice rate and decreased the chalk rice rate and chalkiness. The IAWD and CF treatments had similar SPAD values and Pn at the heading–flowering stage, and grain yield, while the AWD treatment significantly reduced those values, relative to the CF treatment. The IAWD and AWD treatments significantly increased WUE, milled rice rate, head rice rate, peak viscosity, and breakdown, but decreased water use, LAI, chalky rice rate, chalkiness, cool viscosity, and setback. These results suggest that the adoption of IAWD with 15 t ha–1of zeolite application could reduce irrigation water use, increase grain yield and improve grain quality in rice.
