摘要
利用来源广泛且成本低廉的木屑作为主要成分制成不同复合基质,研究其理化性质及其栽培樱 桃番茄的效果。结果表明,以木屑为主要成分制成的复合基质在总孔隙度、通气孔隙度、田间持水量及 pH等理化性质方面优于以泥炭为主要成分的复合基质(60％泥炭+20％细沙+20％珍珠岩),其中以复合 基质(60％木屑+40％煤炉渣)综合性状表现最优,另外其在栽培樱桃番茄过程中的保水保肥能力也最 强,产量表现也最佳,比对照增产30．3％,并且果实在VC、可溶性固形物、可溶性糖、还原糖等品质指标 上与对照无显著差异,是栽培樱桃番茄较理想的复合基质。
The physicochemical properties of sawdust-compound substrates and their effects on cherry tomato were studied by pot experiment. The results showed that the sawdustcompound substrates were better than the peat-compound substrate （60%peat＋ 20%sand ＋20%perlite） in the physicochemical properties, such as total porosity, aeration porosity, water content and pH. Among them the compound substrate of 60% sawdust＋40% coal cinder （T4） was the best one and also had the biggest capability of conserving water and fertilizer. Therefore T4 got the highest yield increased by 30.3% and had not significant difference in quality compared with the control. As a conclusion, T4 was an appropriate compound substrate for cherry tomato soilless culture.
