| 摘 要： | 为探讨盐碱胁迫对加工番茄生理生长和和干物质积累的影响,采用桶栽试验方法,人工配制不同盐碱程度的土壤(CK:1.5g/kg,S1:4g/kg,S2:7g/kg,S3:10g/kg),研究滴灌条件盐碱胁迫下加工番茄生长指标、生理指标、干物质积累和产量的变化规律。结果表明:S1处理对加工番茄的生长指标、净光合速率、蒸腾速率、气孔导度、叶片水分利用效率及叶绿素含量均有一定程度的促进作用,但与CK处理无显著性差异(P0.05);S2与S3处理对以上指标均有一定的抑制性,最小值均出现在S3处理,但在生育后期,S2与S3这2个高盐碱处理下,加工番茄的气孔限制值降低,普遍低于S1与CK处理(P0.01),说明在生育后期高盐碱胁迫下加工番茄光合能力的下降主要是由高盐碱胁迫导致叶片气孔关闭的非气孔限制因素造成的;S1处理使加工番茄增产2.1%,而S2与S3处理因抑制加工番茄生长,使其分别减产18.7%和65.4%;果实膨大一期是加工番茄生长发育的一个非常重要时期,此时,加工番茄长势迅速,干物质积累加快,达到全生育期的最大值。研究结果为新疆盐碱地加工番茄栽培管理技术提供理论依据。

| Abstract: | In order to investigate the effects of salt and alkali stress on growth and dry matter accumulation of processing tomato, different salt content soils (CK:1.5 g/kg, S1:4 g/kg, S2:7 g/kg and S3:10 g/kg) were prepared by barrel planting test, the growth index, physiological index, dry matter accumulation and yield of processing tomato under saline alkali stress and drip irrigation condition were studied. The results show that the treatment of S1 promoted the growth index, net photosynthetic rate, transpiration rate, stomatal conductance, leaf water use efficiency and chlorophyll content of processing tomato, but there was no significant difference between this treatment and CK (P>0.05). S2 and S3 treatments had a certain degree of inhibition on the above indicators, most of the maximum or minimum values appeared in S3 treatment, however, at the later growth stage, the stomatal limitation values of processing tomato decreased in the high salinity treatments of S2 and S3, which were generally lower than those of S1 and CK treatments (P<0.01), indicating that the decline of photosynthetic capacity of processing tomato under high saline alkali stress at the later growth stage was mainly caused by the stomatal closure of the leaves, and which was caused by high saline alkali stress. S1 treatment increased the yield of processing tomato by 2.1%, while S2 and S3 treatments reduced the growth of processing tomato by 18.7% and 65.4% respectively. The first stage of fruit expansion was a very important period for the growth and development of processing tomato. At this stage, the processing tomato grew rapidly and the accumulation rate of dry matter was accelerated, reaching the maximum value of the whole growth period. The research results could provide theoretical basis for cultivation and management techniques of processing tomato in saline alkali soil of Xinjiang. |
