| 摘 要： | 本试验以普通栽培型番茄‘辽园多丽’为试验材料，采用不同粒度保水剂进行土壤拌施，研究了其对番茄幼苗生长发育的影响，为生产上获得壮苗、节约水资源服务。结果表明，不同粒度的保水剂土壤拌施能提高番茄幼苗的株高、茎粗、单位面积叶片重、根茎叶的干鲜重，能够提高G值和壮苗指数，促进番茄幼苗功能叶的光合作用，番茄幼苗功能叶的叶绿素含量和净光合速率均提高。综合不同粒度保水剂处理后对番茄幼苗生长发育的影响，以中等粒度的保水剂处理效果最好。 |

| Abstract: | Tomato cv. ‘Liaoyuanduoli’ was cultivated in order to study the effects on the growth and development of tomato seedlings by super absorbent polymers with different granularity in soil. The results showed that the height, stem diameter, the weight of leaf blade, the fresh and dry weight of tomato seedlings were increased. G value and sound seedling index were also improved. The photosynthesis of function leaves in tomato seedlings was enhanced. The chlorophyll contents and net photosynthesis rate of tomato function leaves were increased. Together, the results demonstrated that the medium granularity of super absorbent polymers had the best treatment efficiency in the growth and development of tomato seedlings. |
