Abstract

为了探寻微润灌溉在日光温室的适宜应用技术参数, 以膜下滴灌为对照(CK), 设置3 种微润管埋深
(10 cm、20 cm、30 cm)和3 种密度[2 行番茄埋设1 条(1 管2 行)、2 条(2 管2 行)、3 条(3 管2 行)微润管], 研
究了微润管不同埋深及密度对日光温室番茄生长、产量及品质的影响。试验结果表明, 与CK 相比, 微润灌溉
更有利于日光温室番茄的生长。番茄的果实横径、单果质量、单果体积、总产量及灌溉水分利用效率增加显
著, 分别较CK 平均增加8.58%、11.99%、18.79%、60.93%和103.40%, 平均节水37.73%。微润灌溉显著提高
了番茄果实维生素C、可溶性糖及糖酸比的含量, 较之CK 平均增幅分别为27.07%、4.48%和21.38%。相同
微润管密度下, 番茄的综合品质表现为: 埋深30 cm>埋深10 cm>埋深20 cm; 相同埋深下, 表现为: 1 管2 行>2
管2 行>3 管2 行。番茄的株高、茎粗、果实形态及总产量, 随微润管埋深的增加而减小, 随微润管密度的增

率、品质以及微润管的经济成本等因素, 埋深10 cm, 1 管2 行(番茄总产量为87.38 t·hm-2, 灌溉水分利用效率

Other Abstract

Tomato (Solanum lycopersicum Mill.) is one of the vegetables widely cultivated in solar greenhouses in North
China. As irrigation is the main source of soil moisture in solar greenhouse, it is very important to select appropriate irrigation
methods and technical parameters to improve agricultural production, keep greenhouse air humidity, and reduce the incidence
of pests and diseases. Moistube irrigation is a new underground irrigation technology with semi-permeable membrane as the
core material which provides water to crop root zone soils in a slow and continuous flow. The advantages of this new irrigation
technology include energy saving, low operation cost, easy operation, good anti-clogging performance, less deep leakage, etc.
However, this technology is still in experimental stage and therefore has not been applied at large scale, and some important
parameters needed to be optimized. In this experiment, drip irrigation with mulch was used as control to explore suitable technical
parameters of moistube irrigation in solar greenhouse conditions. Three depths (10, 20, 30 cm) and three densities (one,
two and three moistubes with two lines of tomatoes in one planting ridge, respectively expresses as 1 tube with 2 lines, 2 tubeswith 2 lines, 3 tubes with 2 lines) were set up to study the effect of different depths and densities of moistube on the growth,
yield and quality of tomato in solar greenhouse conditions. The experiment was done from October 2015 through April 2016 in
a 108 m by 8 m solar greenhouse (108°02′E, 34°17′N) in Yangling Agricultural Hi-tech Industries Demonstration Zone,
Shaanxi Province, China. The results showed that moistube irrigation enhanced the growth of tomato compared with the drip
irrigation with mulch. Compared with control, moistube irrigation increased fruit diameter, weight, volume, total yield and
irrigation water use efficiency by 8.58%, 11.99%, 18.79%, 60.93% and 103.40%, respectively. Our results suggested that water-
saving under moistube irrigation conditions was as high as 37.73%. For tomato quality, compared with control, the contents
of vitamin C, soluble sugar and sugar-acid ratio also increased under moistube irrigation, with average increasing rates of
27.07%, 4.48% and 21.38%, respectively. In terms of comprehensive quality of tomato, the moistube depth was in the order of
30 cm > 10 cm > 20 cm under the same moistube density, the moistube density was in order of 1 tube with 2 lines > 2 tubes
with 2 lines > 3 tubes with 2 lines under the same moistube depth. In general, plant height, stem diameter, fruit shape and total
yield of tomato decreased with increasing moistube depth. These parameters also increased with increasing moistube density.
However, stem diameter and irrigation water use efficiency decreased with increasing moistube density. Based on total yield,
irrigation water use efficiency and quality of tomato and the economic cost of moistube and other factors, 10 cm depth and 1
tube with 2 lines (with total tomato yield of 87.38 t·hm-2, irrigation water use efficiency of 108.91 kg·m-3, and third in comprehensive
quality rank) were the most suitable technical parameters for moistube irrigation in solar greenhouse condition.
