- 摘要:
- 以西瓜种子为试材，以木薯渣、泥炭、蛭石和珍珠岩为基础原料，以不同水平的羊粪、硝酸钙、缓释肥和硫酸亚铁为辅助原料，配制成9个育苗基质配方，综合比较了各育苗基质对西瓜生理和生长指标的影响。结果表明：在T3基质配方上（羊粪、硝酸钙、缓释肥、硫酸亚铁配方组合分别为10.0、1.5、1.5、10.0 kg/m3）西瓜的育苗效果最好，出苗率为93.8%，叶绿素含量比对照提高了37.7%，株高和茎粗均极显著高于对照，西瓜幼苗的干鲜重最大，与对照相比，分别增加了50%和51.3%，壮苗指数也最高，且极显著高于对照；其次为T5（羊粪、硝酸钙、缓释肥、硫酸亚铁配方组合分别为30.0、1.0、1.5、3.0 kg/m3）和T2（羊粪、硝酸钙、缓释肥、硫酸亚铁配方组合分别为10.0、1.0、1.0、5.0 kg/m3）基质配方。
- Abstract:
- Taking seeds of watermelon as material，with the substrate that was made up by cassava dregs，peat，perlite and vermiculite as main raw，and different levels of sheep manure mixed with camciumnitrate，slow-release fertilizer and ferrous sulfate as subsidiary raw，nine different substrates were screened，growth and physiological indexes of watermelon seedlings were comprehensively compared.The results showed that the watermelon seedlings planted in T3 (sheep manure，camciumnitrate，slow-release fertilizer，ferrous sulfate that respectively 10.0,1.5,1.5,10.0 kg/m3) substrate were better than other substrates.The emergence rate was 93.8%.The chlorophyll content increased by 37.7% compared with control.The data of plant height and stem diameter were significantly higher than that of control.The fresh and dry weight were both the biggest，increased by 50% and 51.3% compared with control.The seedling strength index was the highest and significantly higher than that of control.Secondly，that were T5(sheep masure，camciumnitrate，slow-release fertilizer，ferrous sulfate that respectively 30.0,1.0,1.5,3.0 kg/m3) and T2(sheep masure，camciumnitrate，slow-release fertilizer，ferrous sulfate that respectively 10.0,1.0,1.0,5.0 kg/m3) formula.
