日光温室地膜覆盖对春番茄生长发育的影响

Effect of Plastic Film Covering on the Furrow Surface in the Sunlight Greenhouse on the Growth of Spring Tomato

日光温室地膜覆盖春番茄试验结果表明，地膜覆盖增加了地温，促进了番茄的生长发育，提高了前期产量，增加了产值，其中以高畦地膜覆盖效果最好，平畦地膜覆盖次之，但对番茄的总产量没有显著影响。

The experiment of plastic film covering on the furrow surface of the spring tomato field in the sunlight greenhouse was carried out.The results showed that the plastic film covering on the furrow surface, raised the soil temperature, promoted the growth of tomato, raised the yield at early stage and the output value, while it had no obvious effect on the total yield of the tomato.The results also showed that effect of plastic film covering on the high furrow surface was much better than on the flat furrow surface.
