摘要
为提高钾肥使用效率,通过施用不同浓度钾肥(10,20,30kg·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20kg·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10kg·hm^-2和CK处理,与钾肥浓度30kg·hm^-2处理差异不明显,但平均值高于处理30kg·hm^-2处理,所以钾肥浓度20kg·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20kg·hm^-2。
In order to improve the efficiency of potassium fertilizer,the effects of different concentrations of potassium(10,20,30 kg ·hm^-2 ) on growth and fruit quality of three tomato lines 73-882,No.1 and 73-826 were compared.The results showed that the potassium concentration was too low and the nutrient elements were insufficient,which was not conducive to tomato growth and development.The potassium concentration was too high,but inhibited the physiological growth and development of tomato plants.At the potassium fertilizer concentration of 20 kg ·hm^-2 ,the growth and quality of the three tomato lines showed the best,which was significantly higher than the potassium fertilizer concentration of 10 kg ·hm^-2 and CK treatment.There was no significant difference between potassium fertilizer concentration 20 kg ·hm^-2 treatment and potassium fertilizer concentration 30 kg ·hm^-2 treatment,but the average value was higher than that of 30 kg ·hm^-2 .Therefore,potassium fertilizer concentration 20 kg ·hm^-2 was the best potassium concentration for tomato growth and development.Considering the growth and development of tomato and fruit quality index,the most suitable tomato lines in Jilin was 73-882,and the most suitable potassium concentration for tomato growth and development was 20 kg ·hm^-2 .
