摘要: 在春茬番茄的基础上开展第2 茬(秋冬茬)试验,以“京番301”番茄品种为试验材料,采用单因素完全随机区组试验设计、沙土槽培的栽培技术,研究微咸水不同灌溉方式对番茄果实白熟期、转色期、成熟期各部位糖的组成和含量及糖代谢相关酶活性的影响。结果表明:1)在微咸水直接灌溉下,番茄果实的可溶性糖含量均高于其他几个处理,而在淡水直接灌溉下果实的淀粉含量高于微咸水灌溉且差异显著;2)微咸水灌溉可以提高番茄果实内转化酶和蔗糖合成酶的活性,其中微咸水直接灌溉转化酶活性最高,按次轮灌次之,淡水直接灌溉转化酶活性最低;3)淡水直接灌溉番茄产量最高,其次为微咸水和淡水按次轮灌,微咸水直接灌溉和混合水灌溉产量均较低;4)不同的微咸水灌溉方式均会导致土壤盐分的积累,其中微咸水直接灌溉的土壤盐累积最严重,微咸水和淡水按生育期轮灌次之,而混合水处理的土壤盐累积最低。结合番茄产量和土壤盐分、养分积累情况,认为微咸水和淡水按次轮灌为最佳灌溉方式。

Abstract: Based on the first crop experiment (spring), we carried out the second crop experiment in the autumn and winter of 2016, with the“Jingfan 301”tomato cultivar as the experimental material, by a single-factor completely randomized block design, and studied the effects of different brackish water irrigation patterns on the tomato composition and yield, and the activities of glucose metabolism related enzymes during the white mature, color turning and mature stages of tomato fruits. The results showed as follows: 1) The content of soluble sugar in tomato fruits under the direct brackish water irrigation was higher than that under other irrigations, and starch content under the direct fresh water irrigation was higher than under the brackish water irrigation with significant difference. 2) Brackish water irrigation improved the activities of invertase and sucrose synthase in tomato fruits, and the invertase activity was the highest under the direct brackish water irrigation, followed by brackish water and fresh water irrigation in sequence, and the lowest under the direct fresh water irrigation. 3) The tomato yield was the highest under the direct fresh water irrigation, then followed by the brackish water and fresh water irrigation in sequence, and the yield under the direct brackish water irrigation and brackish water∶fresh water=1∶1 irrigation was lower. 4) Different irrigation patterns of brackish water could lead to the accumulation of soil salinity. Among them, soil salt accumulation was the most serious under the direct brackish water irrigation, followed by the brackish water and fresh water irrigation according to the tomato growth period, but the least serious was under the brackish water∶fresh water=1∶1 irrigation. Combined with tomato yield, soil salinity and nutrient accumulation, it is considered that the brackish water and fresh water irrigation in sequence is the best irrigation pattern.
