椰糠替代草炭作番茄穴盘育苗基质的研究

Study on Substitution of Peat with Coconut Chaff as Substrates on Growth of Tomato Seedlings

以椰糠、草炭、蛭石和珍珠岩为基质,按照不同配比混合,研究其对番茄"小凤仙"出苗率、株高、茎粗、叶面积、根冠比、壮苗指数、根系活力等生长指标的影响,筛选出最佳替代草炭的育苗基质配比。结果表明:椰糠处理组T2(椰糠∶草炭∶蛭石∶珍珠岩=2∶2∶4∶4)的株高、茎粗、叶面积、干物质积累及壮苗指数等各项指标均优于其它椰糠处理组,与对照组CK(椰糠∶草炭∶蛭石∶珍珠岩=0∶1∶1∶1)无显著性差异,可以推荐作为番茄育苗基质。

Using tomato ‘Xiao Fengxian＇as the experimental material,effect of different formula substrate of coconut chaff,peat,vermiculite and perlite on tomato emergence rate,plant height,stem diameter,leaf area,ratio of root to shoot,strong seeding index,root activity were studied,in order to find the best substrate formula.The results showed that plant height,stem diam,leaf area,dry matter accumulation and strong seeding index of the coconut chaff processing group T2（coconut chaff∶peat∶vermiculite∶pearlite=2∶2∶4∶4）were close to the control group CK（peat∶vermiculite∶perlite=1∶1∶1）,without significant difference with CK,it was better than other treatments,so it could be recommended as tomato seedling substrate.
