| 摘要: |
| 【目的】探索适合日光温室椰糠袋培条件下黄瓜优质高产的的灌溉模式，丰富设施蔬菜无土栽培节水灌溉理论体系，以期为设施黄瓜椰糠基质栽培的精准水分管理提供理论依据与技术支撑。【方法】以“津优35号”黄瓜为试验材料，选用椰糠袋的栽培模式，采用单因素完全随机区组试验设计，在结瓜期前设5种灌水量，分别为0.6 L/（株·d）（r1）、0.8 L/（株·d）（r2）、1.0 L/（株·d）（r3）、1.2 L/（株·d）（r4）、1.4 L/（株·d）（r5），研究日光温室椰糠袋培条件下灌水量对黄瓜生长、产量及品质的影响。【结果】灌水量为r3处理的黄瓜株高、茎粗、叶面积最大，含色素量、净光合速率、根系活力最高，单宁量和硝酸盐量最低，单瓜质量最重，产量较高；r2处理的产量最高，基质相对含水率较为适中。【结论】综合考虑，灌水量为1.0 L/（株·d）（r3）的黄瓜植株产量高（平均1.92 kg/株）、品质较好（单宁量和硝酸盐量分别为0.46 mg/kg和23.28 μg/g），水分生产力较高（20.1 kg/m3），可以作为日光温室黄瓜椰糠袋培条件下的高产优质高效灌溉模式。 |

| Abstract: |
| 【Objective】The cultivation of high-quality vegetables in soilless substrates has increased significantly in recent years to meet rising market demand. In greenhouses, optimizing irrigation management is critical for sustainable vegetable production. Taking cucumber grown in coconut coir substrate bags as an example, this study experimentally investigates the effects of irrigation amount on cucumber growth, yield, and fruit quality.【Method】The experiment was conducted in a solar greenhouse using cucumber cultivar ‘Jinyou No. 35’ as the model plant. There were five irrigation treatments that irrigated 0.6 L/(plant·d) (R1), 0.8 L/(plant·d) (R2), 1.0 L/(plant·d) (R3), 1.2 L/(plant·d) (R4), and 1.4 L/(plant·d) (R5) of water during the fruiting stage, respectively. Plant growth parameters, including plant height, stem diameter, leaf pigment content, photosynthetic parameters, root activity, yield, fruit quality, and water use efficiency, were measured and analyzed for each treatment.【Result】Irrigating 1.0 L/(plant·d) resulted in the highest plant growth rate, photosynthetic capacity, root activity, and single fruit weight, but the highest total yield was obtained in the 0.8 L/(plant·d) treatment. Irrigating 1.0 L/(plant·d) produced the best fruit quality with the lowest tannin and nitrate contents.【Conclusion】Considering plant growth, yield, water productivity, and fruit quality, an irrigation level of 1.0 L/(plant·d) was optimal for achieving high-yield, high-quality, and high-efficiency production for cucumber in coconut coir substrate cultivation in solar greenhouses. |
