不同比例生物炭替代泥炭栽培基质对西瓜幼苗生长的影响
Effect of Different Substitution Ratio of Peat with Biochar as Substrates on Growth of Watermelon Seedlings
摘要
Abstract
[ Objective] To find the best substitution ratio of peat in substrate formula with biochar.[ Method] Biochar, peat, coconut chaff, vermiculite and perlite were used as experimental substrate materials to study the effect of different proportion of biochar and peat on physical and chemical properties of substrate and growth of watermelon seedlings.[ Result] With the increasing proportion of biochar, bulk density and water-holding porosity of substrate decreased while pH and total porosity increased.The indicators all reached the requirement of ideal sub-strate.There was no significant difference in germination rate of different treatments, but the plant height, stem diameter, aboveground fresh weight, healthy seedling index and root activity of watermelon seedlings firstly increased, and then decreased.Index of watermelon seedling of T2 treatment (biochar:peat=2:3) was better than other treatments.[Conclusion] Biochar could be recommended as a replacing material of peat which could coordinate substrate water and nutrient condition and promote seedling growth.关键词
