| 摘 要： | 以“金冠1号”番茄为试材,研究了不同钾肥施用量对番茄植株生育、氮钾吸收的影响.结果表明:不同钾肥的施用量对番茄茎高和茎粗具有显著的促进效果.10 kg/667m2的施钾量能显著促进果实中钾的积累,钾素的分配呈果＞茎＞根＞叶的趋势,果实中含氮量最高,与其它处理差异显著.在一定范围内,随着施钾量的增加,产量明显提高,在施钾量达到10 kg/667m2水平时,产量最高,平均为14 546.2 kg/667m2.

| Abstract: | Taking’Jinguan No.1’tomato as test material,the effect of the different amount usage of K fertilizer on tomato plant growth and the nitrogen-K absorption were studied.The results showed that the different amount usage of K fertilizer had a significant promoting effect on the tomato stem height and diameter.It was significant different from other treatments when the usage K fertilizer got 10 kg/667m2,under the 10 kg/667m2condition,K fertilizer could significantly promote the accumulation of K in the fruit,and the distribution of K fertilizer showed the fruit>stem>root>leaf trends.The results also showed that within a certain range the tomato yield could improved significantly as the K fertilizer increased,when the usage of K fertilizer got the 10 kg/667m2level,the amount of tomato yield was the highest,the average tomato yield could get 14 546.2 kg/667m2. |
