生物氢烷工程沼渣用于油菜及菠菜育苗的效果 总被引:5,自引:3,他引:2
为探究将生物氢烷工程沼渣应用于蔬菜育苗基质生产的可行性,以油菜品种"华绿四号"、菠菜品种"先锋菠菜"为材料,按不同体积比将生物氢烷工程沼渣与土壤或草炭、蛭石和珍珠岩三者混配作为育苗基质,通过穴盘育苗试验研究生物氢烷工程沼渣对基质理化性质和油菜、菠菜幼苗生长的影响。结果表明:添加生物氢烷工程沼渣可显著改善基质的容重、总孔隙度、有机质含量、pH值和电导率EC(electronical conductivity)值等理化性质;适宜配比的生物氢烷工程沼渣对幼苗生长发育有一定的促进作用,其中T6(生物氢烷工程沼渣20%、草炭30%、蛭石25%、珍珠岩25%)的基质配方较为适宜,T6中油菜出苗率显著高于CK3(草炭50%、蛭石25%、珍珠岩25%)(P0.05),提高了14.3%,菠菜出苗率提高了12.4%,幼苗的株高、茎粗、单株叶面积显著高于或接近CK3(P0.05),幼苗根冠比和壮苗指数与CK3无显著差异;添加生物氢烷工程沼渣可使幼苗地下部生物量显著升高(P0.05),促进根系生长,使幼苗地上部、地下部生物量分配更加均衡。因此,生物氢烷工程沼渣具有一定的肥效,可部分替代草炭用于叶菜育苗基质生产,但使用前可考虑进行好氧堆肥处理进一步腐熟或与氮肥配施以提高肥效。 相似文献

For 3 years, different types of growing media were evaluated in nursery-produced tomatoes (Lycopersicum esculentum Mill. cv “Atletico”). Five mixtures of substrates were used: old peat (65%) + white peat (30%) + perlite (5%), old peat (65%) + MSW compost (30%) + perlite (5%), MSW compost (65%) + white peat (30%) + perlite (5%), MSW compost (95%) + perlite (5%) and MSW compost (50%) + cocofiber (50%). Various seedling indices were measured in order to assess the quality of the nursery-produced plant. The quality of the MSW compost used (pH, salinity, organic matter) bore a strong influence on results. Electrical conductivity (EC) values of the MSW compost of over 9 dSm?1 produced poorer quality tomato seedlings in the mixture of substrates with peat. The use of MSW compost as the only substrate and the mixture of MSW compost with cocofiber had a lower growth index and poorer performance than the standard peat mixture. However, growth and development of the tomato seedlings in the mixture: old peat (65%) + MSW compost (30%) + perlite (5%) were similar to that obtained with the standard mixture: old peat (65%) + white peat (30%) + perlite (5%). 相似文献

A greenhouse experiment was carried out to investigate the effects of different growing media on some properties of tomato (Lycopersicom esculentum L. cv. Falcato). Four growing media including wheat residue, composted wheat residue, coco peat + perlite, and coco peat + soil were applied in pot experiment with completely randomized design with three replications. The results showed that fruit yield, chlorophyll, and vitamin C contents of tomatoes grown in the composted wheat residue and coco peat + perlite treatments were significantly greater than the other growth media. Fresh weight of root and inflorescence were higher in the tomatoes cultivated in the composted wheat residue pots than the other media. Higher internode length and nutrient concentrations in leaf and fruit at the coco peat + perlite treatment were obtained as compared to the other growth media treatments. According to the results, it can be concluded that the coco peat + perlite can be substituted for by composted wheat residue for the cultivation of tomato. 相似文献

AbstractContainer technology can effectively control soil environment and nutrient status to obtain the optimal plant growth condition. Peat, green waste compost (GWC), soil and perlite were used as substrate materials to study the effects of different substrate ratios on growth and physiology of 1.5-year-old Sequoia sempervirens container seedlings. The optimal substrate ratio of S. sempervirens container seedlings was obtained by L9 (34) orthogonal design and was finally evaluated by principal component analysis. The volume ratio of peat: GWC: soil: perlite of 4: 1.5: 1: 2 was the best substrate ratio for S. sempervirens across all parameters, whose porosity, bulk density (BD) and gas-water ratio (GWR) were within the ideal ranges. The concentrations of total nitrogen (TN) of 1.40% and total phosphorus (TP) of 0.13% were the highest among the nine different substrates. The total potassium (TK) and electrical conductivity (EC) were 0.13% and 0.70?ms cm?1, respectively. In addition, the plant height and ground diameter growing in the substrate were increased by 28% and 39% compared to their respective initial values. The content of peat and GCW had significant effects on growth (p?<?0.01). The GWR in T2 (peat: GWC: soil: perlite = 6: 1: 0.5: 2) and T6 (peat: GWC: soil: perlite = 4: 0.5: 0.5: 1) are not suitable for S. sempervirens container seedlings. The PCA ranking of the 9 groups of substrates is: T8?>?T1?>?T4?>?T3?>?T2?>?T5?>?T7?>?T9?>?T6. The combination of peat, GWC, soil and perlite in an appropriate ratio could provide a good environment for S. sempervirens container seedlings. 相似文献

Chile's seedling production industry has been growing for the last 10 years, and demand has actually reached 1250 million seedlings per year. This system has special relevance due to the high cost of seeds. In addition, there is an increasing demand for substituting synthetic agrochemicals. Therefore, the potential use of plant growth-promoting rhizobacteria (PGPR) in tomato production has been investigated. Before sowing, the micro-organisms provided by Biogram S.A. were inoculated into the substrate diluted in 250 mL/L unchlorinated water. The experiment was laid out in a ‘split-plot’ design with the two plant substrates as main plots and the inoculants as subplots, including six replicates per treatment. Tomato seedlings were grown using two different plant substrates: a mixture of 70% peat and 30% perlite by volume, and a substrate with 20% peat, 20% perlite and 60% compost by volume, both inoculated with Bacillus subtilis or Pseudomonas fluorescens or Bioroot®, which is a commercial product containing B. subtilis, P. fluorescens, Trichoderma harzianum, yeast, algae and Nocardia. For control, uninoculated tomato seedlings were grown on the respective plant substrates. Variance analysis did not identify significant interactions between substrate type (main plots) and inoculation treatment (subplots), P ≤ 0.05. There were significant differences between inoculants (P ≤ 0.05). Means were compared by using the Tukey's multiple range test. Tomato growth in terms of leaf area (cm2/plant) and shoot and root dry weight (g/10 plants) was improved for the seedlings grown on the substrate with 70% peat and 30% perlite, compared to the compost containing an alternative that is valid for both uninoculated perlite peat and all inoculated treatments where perlite peat was outstanding. Inoculation with Bioroot® improved the leaf area, shoot dry weight, root dry weight, radical contact area, volume of roots and root forks compared with the control without inoculation, when both plant substrates were analysed together. Thus, inoculation with Bioroot® can be recommended as an alternative to tomato seedling growers' dependence on synthetic agrochemicals. 相似文献

生物质炭醋糟复配物代替草炭对辣椒幼苗生长的影响 总被引:1,自引:1,他引:0
生物质炭的农业利用日益受到关注。针对草炭资源日益耗竭的问题,以药渣炭、木屑炭和猪粪炭为试验对象,配比一定量的醋糟,分析了不同配比生物质炭复合基质对辣椒幼苗生长的影响,探讨了生物质炭复合基质代替草炭基质的可能性。试验结果表明:生物质炭在与醋糟按4∶2、3∶3、2∶4等不同配比混合后,基质的pH大多数在6.0~7.5,基质的通气孔隙有所提高。综合整个幼苗生育期,含20%生物质炭的各复合基质处理的辣椒幼苗株高、茎粗、叶面积、地上部生物量均显著优于对照草炭基质;含20%、40%药渣炭的基质处理的幼苗根表面积、根体积表现较好,在前期与草炭基质无显著差异,后期显著高于草炭基质。药渣炭和木屑炭与醋糟混配基质的壮苗指数优于草炭处理,其中B1A2(药渣炭∶醋糟∶蛭石∶珍珠岩=4∶2∶3∶1)、B1A4(药渣炭∶醋糟∶蛭石∶珍珠岩=2∶4∶3∶1)、B2A4(木屑炭∶醋糟∶蛭石∶珍珠岩=2∶4∶3∶1)处理的壮苗指数均显著高于其他处理。综合评价各生长指标,B1A2和B1A4处理基质的表现最好,可代替草炭基质在辣椒育苗上应用。 相似文献

Annual vinca (Catharanthus roseus (L.) G. Don ‘Pink Carpet'), geranium (Pelargonium x hortorum L. H. Bailey ‘Jackpot'), and marigold (Tagetes erecta L. ‘First Lady') were grown in a sphagnum peat moss and perlite medium. Plants were irrigated with solutions of different salinity by the addition of 0.0, 1.0, 2.0, 4.0, and 8.0 g/1 of a NaCl and CaCl2 mixture resulting in solution electrical conductivity (EC) values of about 1.3, 3.0, 4.5, 7.9, and 13.9 ds/m, respectively. In another experiment marigold and geranium were grown in solution culture containing the same salt mixture at 0.0, 1.0, 4.0, and 8.0 g/1 with EC values of 1.4, 3.0, 7.4, and 12.5 ds/m, respectively. All species showed some salinity tolerance up to 2.0 g/1 in peat‐perlite and 1.0 g/1 in solution culture as growth reductions were below 10% and no foliar injury occurred. Foliar injury occurred on marigold and geranium, but not annual vinca, at 4.0 and 8.0 g/1 in both growing media. On a concentration basis, recently mature leaves sampled from marigold grown in peat‐perlite contained more chloride (Cl) but less sodium (Na) than geranium and annual vinca. However results of the solution culture experiment showed that, with the exception of 1.0 g/1 treatment, geranium and marigold plants absorbed the same amount of Cl and Na when content was expressed on a mg/g dry weight basis. The low Na concentration in marigold leaves was a reflection of restricted translocation of Na from the roots to the shoots. 相似文献
