以番茄品种“欧官”为试材,研究在底施条件下,不同锌肥用量对番茄生长及产量的影响,深入挖掘京郊春大棚番茄的产量潜力。结果表明,底施锌肥对番茄的生长和产量性状均有一定的促进作用,株高、茎粗、结果数以及叶片叶绿素含量等指标均有小幅的增加;底施1~2 kg锌肥,即可显著增加产量,增产率达8.0%~10.4%。考虑到锌肥的用量少,成本低廉,667 m2施1~2 kg锌肥不失为一种增产、增效的良方。
To study the effect of different amount of zinc fertilizer on the growth and yield of tomato under the bottom-dressing conditions, the tomato variety “OuGuan” was used to study the yield potential of tomato in the greenhouse. The results showed that zinc fertilizer at the bottom had some effects on the growth and yield traits of tomato. The plant height, stem diameter, number of results and chlorophyll content increased slightly. At the end of 1 ~ 2 kg zinc fertilizer, Can significantly increase the yield, yield increase of 8.0% ~ 10.4%. Taking into account the small amount of zinc fertilizer, low cost, 667 m2 Shi 1 ~ 2 kg of zinc fertilizer after all, is a yield, efficiency of the recipe.
