不同食用菌菌糠复配基质对番茄和青花菜秧苗出苗的影响

为研究开发我省来源丰富、经济实惠和性能优良的蔬菜无土育苗基质，采用正交试验设计方法，利用食用菌菌糠茶树菇渣、草菇渣和粘土矿物等材料混合配制蔬菜育苗基质。试验结果表明：不同配方基质对番茄种子出苗率有显著影响，但对青花菜种子发芽率没有显著影响；不同配方基质对番茄和青花菜秧苗壮苗指数都有显著影响。从9个配方基质处理中筛选出一个最适合番茄和青花菜等蔬菜穴盘育苗的无土基质配方--8号基质处理（由茶树菇渣按体积分数0.4、草菇渣按体积分数0.35、珍珠岩按体积分数0.1和粘土矿物按体积分数0.15均匀混配而成），该基质处理的番茄和青花菜种子出苗率高、壮苗指数均中等、pH和电导率也较合适。

Effect of Substrates Mixed with Residue of Various Edible Fungus on the Emergency of Tomato and Broccoli

This experiment was conducted to study and explore a vegetable soilless substrate with the source which was abundant, economical and with good quality. Orthogonal design was employed. Tea mushroom residue, straw mushroom residue, clay mineral and other materials were used as raw materials to make up substrate for vegetable plug transplant production. The results showed that the substrate with different formulations made significant effects on tomato emergency rate, seedling index of both tomato and broccoli, but not broccoli emergency rate. The No.8 made up with tea mushroom residue 0.4 （V/V）, straw mushroom residue 0.35 （V/V）, perlite 0.1 （V/V） and clay mineral 0.15 （V/V）], which was screened from nine formulations, was most appropriate for tomato and broccoli plug transplant production. The emergency rate of tomato and broccoli were highest and the seedling index, pH and conductivity were moderate in No.8 substrate.
