番茄工厂化育苗基质配方试验研究

Effects of Industrial Seedling Substrates on Germination and Growth of Tomato

[目的]为番茄工厂化育苗筛选出育苗效果好、成本低的专用育苗基质。[方法]以椰糠、泥炭、珍珠岩为原料,将3种原料按照不同比例(V/V)混合复配成8种育苗基质,选取康成基质为对照,研究不同配方的基质对番茄幼苗生长的影响。[结果]以椰糠∶泥炭∶珍珠岩分别为4∶5∶1、3∶6∶1、2∶7∶1及泥炭∶珍珠岩为9∶1的基质配方所培育的番茄幼苗各生理状况较为理想。[结论]以椰糠∶泥炭∶珍珠岩为4∶5∶1、3∶6∶1、2∶7∶1及泥炭∶珍珠岩为9∶1的基质配方育苗效果较好,结合成本,可推荐为番茄育苗的专用有机营养基质。

[Objective] To screen out special tomato seedling substrates with high effect and low cost. [Methods]Taking coconut chaff,peat and perlite as raw materials,three kinds of raw materials were mixed in different proportion into seven kinds of substrate. Kangcheng substrate was taken as the control group（ CK）,and the influence of different formula of substrate on tomato seedling growth was studied. [Results]The physiological conditions of tomatoes cultivated by substrate formula 4∶ 5∶ 1,3∶ 6,2∶ 7∶ 1 for coconut chaff,peat and perlite,and the formula 9∶ 1 for peat and perlite respectively were excellent. [Conclusion] Effects of substrate formula 4∶ 5∶ 1,3∶ 6,2∶ 7∶ 1 for coconut chaff,peat and perlite,and the formula 9∶ 1 for peat and perlite are better,and they are preferred in tomato seedling for cultivating special organic substrate of tomato.
