- 摘要:
- 以红果形番茄品种“佳丽14”为试材，在质量比为2∶1∶1的草炭、蛭石、珍珠岩混合基质条件下，研究了2.5、2.7、2.9、4.2株/m2不同种植密度对番茄植株长势、物候期、果实品质及产量的影响，以期为筛选适宜日光温室无土栽培的番茄种植密度。结果表明：同等灌溉条件下，2∶1∶1混合基质上2.5~4.2株/m2栽培密度处理单位面积产量无显著差异，但随着密度的增加，单株平均每穗果坐果数减少，果径减小，灰霉病发病率增加，物候期推迟，维生素C含量降低。北京地区日光温室采用质量比为2∶1∶1的草炭、蛭石、珍珠岩混合基质栽培番茄适宜的密度为2.7~2.9株/m2。
- Abstract:
- Taking‘Jiali 14’ tomato as material which was a red fruit variety，the effect of different panting densities (2.5,2.7,2.9 and 4.2 plants/m2)were planted in the mixed-substrate (peat∶vermiculite∶perlite=Wt 2∶Wt1∶Wt 1=2∶1∶1) in green house and the development of plant，growth period，fruit quality，and the yield of tomato were examined under the same irrigation condition.The results showed that there were no significant differences in yield for 2.5，2.7，2.9，4.2 plants/m2.But the fruit setting and diameter of fruit of each truss decreased，while Botrytis cinerea increased，growth period were delayed and the content of vitamin C were decreased.This experiment suggested that the best density for tomato planting in mixed-substrate was 2.7—2.9 plants/m2 in green house in Beijing.
