钾肥对番茄果实品质的影响

- 摘要:
- 为提高钾肥使用效率,通过施用不同浓度钾肥(10,20,30 kg·hm-2)对3种番茄品系73-882粉番茄、1号粉番茄、73-826粉番茄的生长发育以及果实品质的影响进行比较。结果表明:钾肥浓度过低,营养元素不足,不利于番茄生长发育,钾肥浓度过高,反而抑制番茄植株生理生长和发育。在钾肥浓度20 kg·hm-2时,3个品系番茄的生长发育以及品质均呈现出最佳状态,极显著高于钾肥浓度10 kg·hm-2和CK处理,与钾肥浓度30 kg·hm-2处理差异不明显,但平均值高于处理30 kg·hm-2处理,所以钾肥浓度20 kg·hm-2是最适于番茄生长与发育的钾浓度。综合考虑番茄生长发育及果实品质指标,最适宜在吉林栽培的番茄品系为73-882粉番茄,最适于番茄栽培生长与发育的钾浓度是20 kg·hm-2。
