| 摘 要： | 渗灌、滴灌和沟灌3种灌溉条件下土壤水分分布不同,灌水1d后渗灌土壤含水量最大值出现在30cm深处;滴灌出现在20cm深处,而沟灌0～40cm各土层土壤含水量相差较小,但明显高于渗灌和滴灌。沟灌耕层土壤蒸发损失的水分大于滴灌大于渗灌。渗灌、滴灌有助于番茄植株形态指标的建成,为后期产量的形成奠定了基础,致使渗灌、滴灌番茄产量分别显著和极显著地高于沟灌。

Effect of Irrigation Methods on Soil Water Loss and Water Use Efficiency of Tomato in Greenhouse |
| |
| Abstract: | Soil water distribution is different from seeping irrigation, dripping irrigation and furrow irrigation system, The maximum contents of water appeared at the depth of 30 cm and 20 cm a day after seeping irrigation and dripping irrigation, respectively. In furrow irrigation, the difference of soil water in 0~40 cm after one day of irrigation is not significant, but higher than that in seeping and dripping treatment. Compared with dripping and seeping irrigation, evaporation loss of water from topsoil is the most in furrow irrigation. Seeping and dripping irrigation can improve the plant growth and increase tomato yield. |
