沙地设施番茄苗期基质配方的筛选

The Selection of Sandy Media Formula of Seedling Tomato in Greenhouse

以番茄品种金棚一号为试材,以腐熟的锯末为主要原料,与腐熟的猪粪、鸡粪、沙子按照一定的比例组成的四种复合基质:A、锯末∶有机肥∶沙子=2∶3∶5;B、锯末∶有机肥∶沙子=3∶2∶5;C、纯粪∶沙子=2∶3;D、新天地育苗基质∶沙子=1∶1。以CK1取自杨凌新天地的育苗基质,与CK2以沙化土为对照研究了不同基质对番茄幼苗株高、径粗、叶绿素含量、地下鲜重、地上鲜重、地下干重、地上干重、壮苗指数的影响,并对其基质理化性质进行了分析,结果表明:处理B的番茄幼苗株高最高,幼苗径粗最好,叶绿素含量最多,地上鲜重、地下鲜重、地上干重、地下干重最高,壮苗指数最高,并且与其他处理之间存在显著性差异。各处理都显著高于两对照。处理B的基质理化性质表现的最好,较接近于理想基质。

The study used tomato variety-Jinpeng 1st as the test material,fully decomposed sawdust as the main materials combining with fully decomposed pig manure,chicken manure and sand according to a certain percentage.The four types of composite matrix are formed as following：A：sawdust∶manure∶sand= 2∶3∶5;B：sawdust∶manure∶sand= 3∶2∶5;C：pure manure∶sand= 2∶3;D：new horizons substrate∶sand= 1∶1.The effects of different substrates were studied on the plant height,diameter,chlorophyll content and fresh weight of ground,fresh weight on ground,dry weight of ground,dry weight of ground and dry weight of tomato seedlings by comparing CK1 from Yangling Xintiandi and CK2.Strong Index of seedlings is investigated.The physical and chemical properties of matrix are analyzed,the main results are as follows：The seedling height of tomato treatment B is the maximum;the result of treatment B is featured with highest number in terms of seedling,seedling stem diameter,chlorophyll content,above-ground and under-ground fresh weight,above-ground and under-ground dry weight and fertilized seedling.And the result of each treatment is significantly higher than that of the two controls;The matrix physical and chemical properties of treatment B is the best,much closer to the ideal matrix.
