摘要
为考察废旧岩棉对番茄生长和品质的影响,以进口新、旧岩棉,国产新、旧岩棉,椰糠作为栽培基质,研究不同栽培基质对现代温室番茄生长、光合作用、果实品质、产量和营养液排液矿质元素含量的影响。结果表明:不同基质处理番茄株高、茎粗、节间长度、最大叶长宽、净光合速率、果实主要品质参数以及产量差异均不显著,使用进口旧岩棉和国产旧岩棉均可以正常生产越冬茬番茄。番茄栽培中应该注重排液营养液的定期检测分析,使用旧岩棉基质栽培番茄,营养液中应适当提高S、Mn、Zn、Mo的含量;椰糠基质栽培应注重S、Fe、Mn、Zn、Mo的供给;为便于营养液配方及灌溉策略管理,温室同一灌溉区最好使用同一种栽培基质。该研究为温室岩棉循环利用提供了理论和技术支撑,可以有效提升岩棉基质的使用效率。
In order to explore the effects of waste rock wool on growth and fruit quality of tomato in modern greenhouse,the imported new and waste rock wool,domestic new and waste rock wool,and coconut coir were used as substrates to study the effects of different substrates on tomato growth,photosynthesis,fruit quality,yield and mineral element content of drain nutrient in modern greenhouse.The results showed that there were no significant differences in tomato plant height,stem diameter,inter-node length,maximum leaf length and width,net photosynthesis rate,the main fruit quality parameters,and yield in different substrate treatments.Both imported waste rock wool and domestic waste rock wool could be used to cultivate overwintering tomatoes normally.The drain nutrient should be regular test and analysis in tomato cultivation,and the content of S,Mn,Zn,and Mo should be appropriately increased in the nutrient solution when using the waste rock wool substrate.The coconut coir cultivation should pay attention to the supplying of S,Fe,Mn,Zn,and Mo,and should use the same substrate in the same irrigation area of the greenhouse,as to facilitating the management of nutrient recipe and irrigation strategy.The research provided theoretical and technical support for the recycling of rock wool in greenhouses,and could effectively improve the use efficiency of rock wool.
