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。
In this experiment, ’LiaoYuan Duoli’, an ordinary cultivated tomato, was used as the experimental material. Different types of water-retaining agents with different particle size were used for soil mixing. Their effects on growth and development of tomato seedlings were studied, and strong seedlings were obtained for production and water resources were saved. The results showed that soil water conservation agent with different particle size could improve plant height, stem diameter, leaf weight per unit area, fresh and dry weight of rhizome and leaves, increase G value and strong seedling index, and promote photosynthesis of functional leaves of tomato seedlings The chlorophyll content and net photosynthetic rate of functional leaves of tomato seedlings increased. Comprehensive treatment of different particle size water-retaining agent on tomato seedling growth and development, the middle-sized water-retaining agent best.
