- 摘要:
- 以“佳粉18号”番茄为试材，研究了不同基肥施入水平与施入深度对温室番茄不同生育时期生长、光合速率与蒸腾速率日变化的影响。结果表明：不同施肥处理对番茄不同生育期叶片的绿色度与光合速率以及蒸腾速率变化呈明显的正相关关系，而番茄叶片SPAD值随生育的进程呈增加的趋势；在基肥总量相同的情况下，分散施入60 cm深度番茄植株生长速率与各生育期叶片光合与蒸腾速率都要大于分散施入表层30 cm土壤处理；在基肥施入深度相同的条件下，基肥水平较高的处理番茄植株生长速率与盛果期光合与蒸腾速率都要大于低水平与不施处理。总体表明，表层与底层30 cm土壤分别施入N 1 200 kg/hm2、K 600 kg/hm2、P 600 kg/hm2的基肥水平更有利于番茄盛果期生长的需要。
- Abstract:
- Taking ‘Jiafen No.18’ tomato as material，the effect of different base fertilization level and soil depth on the growth,photosynthetic rate and transpiration rate of tomato in solar greenhouse were studied.The results showed that leaves SPAD value,photosynthetic rate and transpiration rate at different growth stages had significant positive correlation under different treatments.And leaves SPAD value increased with the growth process for every treatment.The plant growth speed,photosynthetic rate and transpiration rate at different growth period with the treatment of base fertilization for 60 cm soil depth were better than the base fertilization for 30 cm soil depth treatment under the same amount of base fertilization level.The plant growth speed,photosynthetic rate and transpiration rate at full bearing period with high base fertilization level treatments were better than the low base fertilization level treatments and no fertilization under the same depth of base fertilization.All results indicated that N 1 200 kg/hm2,K 600 kg/hm2,P 600 kg/hm2 base fertilization level for 30 cm surface soil and 30 cm bottom soil respectively were more recommend for the solar greenhouse tomato production.
