Title: Effect of Different Fertilizing Amount of Potash on the Absorption of Nitrogen and Potash of Tomato in Greenhouse
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 fruitstemrootleaf 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.
