摘要: 以黔北地区资源丰富的农业有机废弃物和珍珠岩为基质原料,筛选适合辣椒种植的育苗基质。将老糠灰、珍珠岩以及腐熟后的有机物料A和有机物料B按不同比例混合组成8种处理[V(有机物料A)∶V(有机物料B)∶V(老糠灰)∶V(珍珠岩)分别为1∶4∶5∶0(T1)、2∶3∶4∶1(T2)、3∶3∶3∶1(T3)、4∶3∶2∶1(T4)、4∶4∶1∶1(T5)、3∶4∶2∶1(T6)、3∶2∶4∶1(T7)、4∶1∶5∶0(T8)],以菜园土为对照(CK),对辣椒品种湘辣12号进行穴盘育苗试验,研究不同处理对辣椒幼苗生长的影响。结果表明,除T1处理的水气比和CK的容重不在理想基质的要求范围内,其余处理均能满足辣椒育苗要求。除T1处理的出苗率和成苗率低于CK外,其余7种处理的出苗率和成苗率均高于CK,其中,出苗率比CK提高12.25%~36.79%,成苗率比CK提高12.88%~33.67%。不同育苗基质处理的辣椒幼苗形态指标优于CK(T1处理除外),其中,T3处理的辣椒幼苗株高、茎粗、单株鲜质量、根冠比、壮苗指数以及G值最优。T3处理能够有效地促进辣椒幼苗的生长,可以作为育苗基质应用于辣椒育苗。

Abstract:  This study used agricultural organic waste in northern Guizhou and perlite as matrix material, to screen seedling substrates suitable for pepper planting. Effects of different seedling substrates on pepper plug seedling growth were tested with nine treatments including T1[V(organic material A) ∶ V(organic material B) ∶ V(old ash) ∶ V(perlite) =1∶ 4∶ 5∶ 0) ],T2(2∶ 3∶ 4∶ 1) ,T3(3∶ 3∶ 3∶ 1) ,T4(4∶ 3∶ 2∶ 1) ,T5 (4∶ 4∶ 1∶ 1) ,T6(3∶4∶2∶1) ,T7(3∶2∶ 4∶ 1) ,T8(4∶ 1∶ 5∶ 0) and vegetable garden soil(CK).The pepper Xiangla No.12 was used as plug seedling experimental material.The results showed that all treatments could meet the requirements of the growth of pepper except for the water-gas ratio under T1 treatment and the bulk density under CK treatment.Except T1 treatment,the emerging rate of the other seven treatments was 12.25%—36.79% higher than CK treatment,the survival rate was 12.8%—33.67% higher than CK treatment.The morphological indexes of pepper seedlings treated with different seedling substrates were better than CK treatment( except for T1 treatment).Pepper seedlings under T3 treatment had the highestplantheight,stemdiameter,freshweight per plant,root-shoot ratio,strong seedling indexandG value.TheseresultssuggestedthatT3treatmentcouldsignificantlypromotethegrowthofpepperseedlings andcouldbeanewtypeofpepper seedlingsubstrate.
