| 中文摘要: |
| 为探索有利于提高番茄生长和产量的温室滴灌施肥有
效模式，试验设置了3个灌水下限〔W1(65%
θF)、W2(75%
θF)和W3(85%
θF)〕和3个施肥水平〔F1(低肥)、F2(中肥)和F3(高肥)〕，在设施栽培条件下研究了滴灌施
肥不同灌水下限和施肥量对番茄植株生长、生理特性和产量的影响。结果表明：滴灌施肥条
件下不同的灌水下限和施肥量对温室番茄生长、产量和生理特性都有一定的影响。在同一灌
水下限条件下，增加施肥量可以显著提高番茄株高、叶面积、光合和蒸腾速率、干物质量和
产量，但过高的施肥量反而不利于其生长、干物质累积和产量的提高；在同一施肥水平下，
适当上调灌水下限可以显著增加番茄株高、叶面积和干物质量，过高的灌水下限不利于番茄
的生长、光合速率和产量的提高。在试验的砂壤土中，W2F2处理最有利于番茄的生长、干物
质的形成、产量和水分利用效率的提高。研究还表明，不同水肥处理条件下，番茄的产量与
干物质量和叶片的净光合速率均呈显著的线性相关，番茄叶片的水分利用效率与净光合速率
的变化关系均呈二次抛物线相关。 |

| For the purpose of exploring the effective mode of
fertigation in greenhouse, the experiment was conducted to analyze the effects
of different irrigation threshold and fertilization on growth, physiological pro
perties and yield of tomato. There were three irrigation threshold treatments in
cluding W1 (65%θF), W2 (75%θF) and W3 (85%θF), and three
fertilization treatments including F1 (low)
, F2 (middle) and F3 (high). The results showed that the growth, yield and physi
ological properties of tomato could be modified by different irrigation threshol
d and fertilization. Under certain irrigation threshold, the plant height, leaf
area, photosynthesis and transpiration rate, dry matter production and yield of
tomato could be significantly increased along with the increase of fertilization
amount, while excessive fertilization was detrimental to the growth, dry matter
accumulation and yield improvement of tomato. Under certain fertilization amoun
t, the plant height, leaf area and dry weight of tomato could be improved by rat
ional increase of irrigation threshold, while excessive irrigation threshold was
not conducive to the growth, photosynthetic rate and yield improvement of tomat
o. The treatment of W2F2 was most conducive to the growth, dry matter accumulati
on, yield and water use efficiency of tomato. The experiment also showed that, u
nder different water and fertilization treatments, there was a significant linea
r correlation between the yield and dry matter weight as well as leaf net photos
ynthetic rate, and there was a significant quadratic parabola correlation betwee
n the leaf water use efficiency and net photosynthetic rate. |
