| 摘 要： | 以盖世番茄888为供试品种,采用50孔穴盘进行育苗,育苗基质中设置5个保水剂(沈阳基石)质量分数,研究不同质量分数保水剂对穴盘育苗效果的影响.试验中苗期正常管理,成苗后统一进行干旱控水,待开始有穴盘苗出现萎蔫时,测定相关指标.结果表明,通过壮苗指标和生理指标的测定可以认为,保水剂不但对穴盘苗生长量提升明显,同时对提高穴盘苗生理活性、抗逆性效果显著.因此,适当的保水剂质量分数有利于提高秧苗质量,试验中发现沈阳基石保水剂质量分数以0.2%最佳.

| Abstract: | Using plug seedlings of Gaishi tomato grown in 50-hole tray as experimental materials,the research designed five mass fractions of water retention agent(WAR) to study the influence of WAR on plug seedlings.Normal management was applied during seedling stage.Water control treatments began at trifoliate stage and tested relevant indicators when the control appeared wilting.The results showed that,based on the determination of healthy seedling index and physiological index,WAR improved obviously not only the i... |
