Effect of Potassium Management on Yield and Benefit of Processing Tomato

【Objective】Research applying different K content,application period and different varieties of potash fertilizer on processing tomato yield,the influence of the fertilizer effect.【Method】Through three different applying potash content,three application period and Three different varieties of potash fertilizer,using drip irrigation under membrane planting,in determination of harvest processing tomato plant,fruit weight, yield calculation,analysis of fertilizer efficiency.【Result】1 when potash fertilization period and at the same time,Potash application of 120 kg / hm2dosage of processing tomato yield is higher than the other; 2 when applying potash content phase at the same time,drip irrigation topdressing potassium 50% flowering period and 50% maximum drip irrigation topdressing stage results of processing tomato production,the potash All lowest basal application;3 Potash fertilization period phase at the same time,potassium deficiency,lack of enough k,k content is too high will reduce the economic benefits of processed tomatoes,applying potash content phase at the same time,the economic benefits of drip irrigation the topdressing and 50% period of potash 50% flowering stage drip irrigation topdressing higher than other application period; 4 The highest yield of potash K- KCl treatment of Processing tomato in different varieties of potash fertilizer,was followed by K- K 2 SO 4 、K-KNO 3,and potash fertilizer for K- KCl the best efficiency,followed by K- K 2 SO 4,and lowest K- KNO 3. 【Conclusion】This experiment preliminarily concluded: The most appropriate processing tomato potash fertilizer is 125. 89 kg / hm2,the most suitable drip irrigation topdressing potash fertilization period to 50% flowering period,results 50% drip irrigation topdressing stage,Processing tomato varieties of potash fertilizer,potash for K- KCl in the most appropriate.
