Abstract

通过番茄滴灌试验,研究不同水分亏缺条件下毛管埋深对番茄植株生长、果实形态、产量与品质的影响。结
果表明: 毛管埋深对日光温室番茄产量、灌水量有显著影响( p < 0. 05) ,对灌溉水利用效率和品质无显著影响( p >
0. 05) ; 毛管埋深为20 cm 时,番茄植株生长速度较快,果实横茎较大。轻度与中轻度水分亏缺灌水条件下,毛管埋
深为20 cm 可显著减小C 级( 番茄直径D < 6. 5 cm) 果实比例29. 2%,分别提高A 级( D≥7. 5 cm) 与B 级( 6. 5 cm≤
D < 7. 5 cm) 果实比例16. 6%、2. 0%。番茄产量、灌水量随毛管埋深增加呈先增后减趋势,毛管埋深为20 cm 时,番
茄产量最高,达到66. 44 t /hm2。番茄产量和灌溉水利用效率随灌水下限增加而显著降低( p < 0. 01) ,可通过不同毛
管埋深与灌水下限组合,显著降低番茄灌水量,提高产量和水分利用效率。综合考虑,毛管埋深20 cm,灌水下限为
田间持水量的60%处理组合为关中地区日光温室适宜的滴灌灌溉方式。

Other Abstract

In order to explore the effective way to improve the water use efficiency of tomato in the
sunlight greenhouse,the effects of lateral depths on growth,fruit shape and quality of tomato under
different water deficit were studied through drip irrigation experiment in 2014 and 2015. Results showed
that lateral depth had a significant influence on yield,irrigation amount ( p < 0. 05 ) ,and had no
significant impact on irrigation water use efficiency and quality ( p > 0. 05) . The growth rate of tomato
was faster and fruit diameter was bigger when lateral was buried at 20 cm depth. Under moderate and
moderate-mild water deficit,lateral buried at 20 cm depth could significantly decrease the fruit ratio of C
grade ( fruit diameter D < 6. 5 cm) by 29. 2%,and increase the fruit ratio of A grade ( D≥7. 5 cm) and
B grade ( 6. 5 cm≤D < 7. 5 cm) by 16. 6% and 2. 0%,respectively. The changing trend of yield and
irrigation amount of tomato showed a first increase and then decrease trend with the increase of lateral
depth,the value of yield for lateral depth buried at 20 cm was the highest ( 66. 44 t /hm2 ) . Yield and
irrigation water use efficiency of tomato were decreased significantly with the increase of irrigation
threshold ( p < 0. 01) ,so irrigation amount can be reduced while the yield and water use efficiency of
tomato can be increased by adopting different combinations of lateral depth and irrigation threshold.
Therefore,lateral depth of 20 cm and irrigation threshold of 60% of field capacity would be the most
appropriate treatment combination for tomato cultivation in the sunlight greenhouse in Guanzhong region of
Shaanxi Province. For the observed responses,the information on how the tomato adapted to different
lateral depths under water deficit condition would provide guidance for field production practices as well
as indications of possible mechanisms.
