不同浓度钾对基质栽培樱桃番茄营养生长的影响
Influence of Potassium with Different Concn. on Vegetable Growth of Tomato Cultivated with Substrate
摘要
Abstract
[ Objective ] The purpose was to supply scientific foundation for reasonable application of potassium (K) fertilizer in tomato cultivation. [ Method] With cherry tomato as the tested material,the influences of K with different concn. (3,8 and13 mmol/L,represented with Treatment K3 ,K8 and K13 ) in nutrient solution for soilless culture on the plant height,stem diameter,leaf area and leaf number of tomato was studied in Feb. - Jun. of 2010. [ Result] The stem diameters.and leaf areas of tomato plants in Treatment K8 were extremely significantly bigger and their plant heights and leaf numbers were significantly bigger than that in Treatment K3 and K13. On Jun. 12th ,2010,the average stem diameters,average leaf areas,average plant heights and average leaf numbers of tomato plants in Treatment K3,K8 and K13 were 1.010,1.339 and 1.032 cm;0.262,0.291 and O. 191 m2 ;93.48,112.65 and 101.13 cm;14.0,16.5 and 14.3 resp. [Conclusion]The nutrient solution with potassium conch.8 mmol/L of for soilless culture was more suitable for the growth of cherry tomato.关键词
