- 摘要:
- 以“荷兰布利塔”茄子为试材，通过小区试验，研究了渗灌条件下土壤水分对日光温室秋冬茬茄子生长指标、光合指标、产量及水分利用效率的影响。结果表明：渗灌条件下秋冬茬茄子开花坐果期土壤水分控制下限达到了田间持水率的65%～75%、结果盛期土壤水分控制下限达到了田间持水率的55%～65%时，有利于促进植株的生殖生长和果实干物质的积累，产量和水分生产率均相对较高，且适度水分亏缺有利于果实品质的提高。
- Abstract:
- Taking ‘Holland Bulita’ eggplant as test material，through a plot experiment，the effect of soil moisture on the growth index，photosynthetic index，yield and water use efficiency of greenhouse eggplant with an infiltrating irrigation in autumn-winter were studied.The results showed that the low control limit of soil moisture for eggplant with an infiltrating irrigation in autumn-winter reached 65% to 75% of field moisture capacity during blossom and fruit-setting period，when it reached 55% to 65% of field moisture capacity with a higher yield and higher water productivity during the prime period of fruiting，it was beneficial to the reproduction and growth of the plants as well as the accumulation of fruits dry matter，at the same time a moderate water deficit was good for the improvement of fruit quality.
