中文摘要	为探明不同水肥耦合模式对河西走廊灌漠土日光温室甜椒生长发育和产量的影响,以红色甜椒品种Thialf Rz为材料,采用裂区试验设计,研究了不同田间持水量和肥料组合耦合对甜椒生长和产量及果期叶片光合特性的影响。结果显示,在中等的土壤水分和施肥水平条件下,即土壤田间持水量达75%~90%及肥料组合为氮600 kg/hm~2+五氧化二磷450 kg/hm~2+氧化钾400 kg/hm~2的耦合模式下,果期甜椒植株的高度、茎粗、最大叶面积、叶片含水量及地上部和根系干质量均明显高于其他耦合模式。同时,叶片的PSⅡ原初光能转换效率(F_v/F_m)和PSⅡ活性(F_v/F_o)均表现为最大,叶片实际光化学效率(PhiPSⅡ)和光化学猝灭系数(qP)也最高,光抑制程度最低,光合速率(P_n)最大,小区产量为10.28 kg/m~2,显著高于其他处理。表明在河西走廊灌漠土日光温室中,适合甜椒生长发育的水肥耦合模式为田间持水量为75%~90%,肥料组合为氮600 kg/hm~2+五氧化二磷450 kg/hm~2+氧化钾400 kg/hm~2。
英文摘要	The pepper variety Thialf Rz was selected as material to study the effects of different water and fertilizer coupling modes on growth, yield and photosynthetic characteristics at fruiting period in Hexi Corridor irrigated desert soil greenhouse. The results showed that plant height, stem diameter, maximum leaf area, leaf water content, above-ground dry weight and root dry weight of greenhouse pepper in the treatment of moderate soil moisture and fertilization, which was field capacity of 75%-90% and N 600 kg/hm~2+P_2O_5 450 kg/hm~2+K_2O 400 kg/hm~2 fertilizer coupling mode, were significantly higher than those in other treatments. PSⅡ light energy conversion efficiency (F_v/F_m), PSⅡactivity (F_v/F_o), leaf actual photochemical efficiency (PhiPSⅡ), light chemical quenching coefficient (qP) and photosynthese (P_n)of greenhouse pepper were the highest, while the degree of photoinhibition was the lowest. The pepper yield reached 10.28 kg/m~2, outperforming other treatments. These results indicated that the water and fertilizer coupling mode of field capacing of 75%-90% and fertilizer combination of N 600 kg/hm~2+P_2O_5 450 kg/hm~2+K_2O 400 kg/hm~2 was suitable for the growth and development of sweet pepper in the greenhouse at irrigated desert soil of Hexi Corridor.
