| 摘 要： | 为了分析不同灌溉方式的节水效果和对植物生长发育的影响,通过对大棚西红柿进行沟灌、滴灌和地下灌溉3种灌溉方式的试验,分析不同灌溉方式、灌水量、注射深度对大棚西红柿茎粗、根系活力、产量和西红柿品质的影响。试验结果表明:地下灌溉的节水效果显著高于沟灌和滴灌;而在地下灌溉试验的比较中,当每次注射水量为0.75 L时,西红柿的总产量和根系活力最高;试验同时表明距离地表约30 cm的注射深度时,西红柿的根系活力强,有利于西红柿生长。

| Abstract: | The different irrigation can make the different water-saving effect and impact on crops' growth.In the paper,the furrow irrigation,drop irrigation and subsurface irrigation is adopted to test the relationship between the different irrigation treatments,water consumption and crops' growth.The result testifies that the water-saving effect of the subsurface irrigation is much better than that of the furrow irrigation and drop irrigation.The comparison of subsurface irrigation also shows that the production and the root system's vigor of tomato are strongest when the irrigation water is 0.75 liter and the irrigation depth is 30 centimeter. |
