摘要
以黄瓜为试材,醋糟和锯木屑作为2种主要基质原料,通过设定醋糟、锯木屑和土壤等的不同配比(纯醋糟C、纯锯末J、醋糟∶土=4∶1CT、锯末∶土=4∶1JT、醋糟∶锯末=2.5∶2.5CJ、醋糟∶锯末∶土=2∶2∶1CJT),对比分析基质处理对黄瓜株高、茎粗、叶片数等生长指标及产量的影响,为醋糟和锯末作为设施黄瓜栽培基质的适用性提供理论依据。结果表明:醋糟与锯末等不同配比的各基质处理均具有良好的孔隙度、pH、EC等理化性状,纯醋糟以及添加醋糟比例较高的基质处理还含有较丰富的有效养分含量;不同基质处理对黄瓜生长的影响差异较大,纯醋糟以及添加醋糟的基质处理(C、CT、CJT)可明显促进黄瓜的株高、茎粗的增长和叶片数的增加,而添加锯末的基质处理(J、JT)生长较差,纯锯末处理生长最差;黄瓜单株产量以C和CT处理最高,J处理最低。综合以上结果,C和CT基质处理栽培的黄瓜株高、茎粗、叶片数及果实产量都明显优于草炭和土壤对照,可以作为草炭的替代栽培基质。
Substrate cultivation plays an important role in overcoming continuous cropping obstacles and promoting sustainable development of facility agriculture.In the experiment,wastes of vinegar residue and sawdust were used as growing media for cucumber in greenhouse.Different mixing ratios of vinegar residue compost,sawdust and soil were evaluated（vinegar residue C,sawdust J,vinegar residue∶soil=4∶1CT,sawdust∶soil=4∶1JT,vinegar residue∶sawdust=2.5∶2.5CJ,vinegar residue∶sawdust∶soil=2∶2∶1CJT）as culture substrates to compare the plant height,stem diameter and number of blades of cucumber plants.It was useful for providing the theory basis for the applicability of the cucumber cultivation matrix.The results showed all these substrate treatments were suitable for plant growth with good porosity,pH and EC.C,CT,CJ and CJT substrates contained rich available nutrients.There was a large difference between different culture substrates.The substrates of C,CT,CJT mainly mixed with vinegar residue compost revealed an obvious superior on the growth of the cucumber than those of J and JT mainly composed of sawdust.And J was the worst in all substrates.C and CT had the highest per plant fruit yield,while J was the worst too.Above all,C and CT revealed an obvious superior growth of the cucumber than peat and soil,so that vinegar residue could be alternative to peat as culture substrate.
