摘要： 研究了地表覆盖秸秆、地膜和秸秆加膜对日光温室嫁接和非嫁接黄瓜生长与生理特性的影响.结果表明，地表覆盖可有效促进植株生长，嫁接黄瓜覆盖秸秆加膜、地膜与秸秆的株高和茎粗依次比对照增加91、71、57 cm和0127、0.086、0.111 cm，非嫁接黄瓜增幅较小；地表覆盖可增强光合作用，嫁接黄瓜覆盖秸秆加膜、地膜、秸秆的净光合速率分别比对照增加2.63、2.08与1.36 μmol·m^-2·s^-1，非嫁接黄瓜增幅较小；嫁接黄瓜覆盖秸秆加膜和秸秆的叶绿素含量比对照增加1.8%和3.15%，而覆盖地膜的叶绿素含量降低了3.8%，非嫁接黄瓜的叶绿素含量变幅较小；嫁接黄瓜覆盖秸秆加膜、地膜、秸秆的根系活力比对照提高0.98、0.48和0.8 mg TTC·g^-1FW，同一处理的非嫁接黄瓜根系活力增幅较小；地表覆盖可增加单株干物重，提高早期产量和总产量，嫁接黄瓜覆盖秸秆加膜、地膜与秸秆的单株产量比非嫁接黄瓜分别增加16%、5.3%和3.4%.

Abstract: This paper studied the effects of wheat straw mulching, plastic film mulching, and wheat straw plus plastic film mulching on the growth and physiological characteristics of grafted and non-grafted Cucumis sativus in solar greenhouse. The results showed that compared with the control, the plant height, stem diameter, photosynthetic rate, and root vitality of grafted C.sativus under wheat straw plus plastic film mulching, plastic film mulching, and wheat straw mulching were increased by 91, 71 and 57 cm, 0.127, 0.086 and 0.111 cm, 2.63, 2.08 and 1.36 μmol·m^-2·s^-1, and 0.98, 0.48 and 0.8 mg TTC·g^-1FW, respectively, while non-grafted C. sativus had a less increment. The chlorophyll content of grafted C. sativus under wheat straw plus plastic film mulching and wheat straw mulching was 1.8% and 3.15% higher than the control, respectively, but that under plastic film mulching was 3.8% less than the control. Soil surface mulching increased the dry weight per plant, early yield, and total yield. Under wheat straw plus plastic film mulching, plastic film mulching, and wheat straw mulching, the individual yield of grafted C. sativus was 16%, 5.3% and 3.4% higher than that of non-grafted C. sativus, respectively.
