小麦秸秆复合基质对番茄幼苗生长发育的影响

为了充分利用农业废弃物小麦秸秆,进行草炭替代性育苗基质原料的研发,实现农业资源循环化利用和生态可持续发展。以番茄‘毛粉802’为材料,通过小麦秸秆腐熟物、草炭、蛭石和珍珠岩4种基质原料及1种生物菌肥进行不同体积配比处理,研究不同配比的小麦秸秆复合基质对番茄幼苗生长指标、叶片色素及荧光指标、幼苗叶片理化性质指标、基质生物指标和理化性质的影响,探究适合番茄幼苗生长的小麦秸秆复合育苗基质配方。利用灰色关联法对19项指标进行综合分析。结果表明,V腐熟小麦秸秆∶V蛭石∶V珍珠岩∶V生物菌肥=6∶2.5∶1∶0.5番茄幼苗表现最好,而番茄幼苗在纯小麦秸秆腐熟物上的生长量远远低于其他处理,番茄幼苗的表现最差。

Effect of wheat straw composite substrate on the growth and development of tomato seedlings

In order to make full use of the agricultural waste resource wheat straw, the research and development of alternative seedling substrate raw materials of peat was carried out to realize the recycling utilization of agricultural resources and the sustainable development of ecology. A tomato variety‘Maofen 802’was used as test material in this research,four kinds of substrate materials of wheat straw compost, peat, vermiculite and perlite and one kind of biological fertilizer were treated with different volume ratio, the effect of composite matrix of wheat straw with different ratio on the growth index, leaf pigment and fluorescence index, physical and chemical property index was investigated. The grey relational method was used to analyze the 19 indexes, the results showed that the best composition and ratio of tomato seedling culture substrates was Vwheat straw compost∶Vvermiculite∶Vperlite∶Vbiofertilizer= 6∶2.5∶1∶0.5, while the tomato seedlings which grew on the pure wheat straw decomposed matter showed the worst performance.
