Effect of Potassium Fertilizer on Yield and Quality of Solanum lycopersicum
In order to investigate the effects of potassium fertilizer on Solanum lycopersicum yield and quality,Juancheng County was selected as the test site to compare the effects of different fertilization programs on Solanum lycopersicum yield and quality.Un-der the condition of 15 kg potassium chloride fertilization,the yield and quality of Solanum lycopersicum were higher,and the plant height,stem diameter,fruit weight,fruit length,fruit width,yield and increase rate were 128.38 cm,2.14 cm,168.57 g,6.38 cm,4.57 cm,4 864.02 kg,35.49%,respectively.The mass fractions of lycopene,protein,Vitamin C,soluble sugar,titrable acid and soluble solid were 1.65 mg/hg,1.09 g/hg,23.36 mg/hg,3.99 g/hg,0.42 g/hg and 5.9%,respectively.The results can provide theoretical basis for scientific fertilization of Solanum lycopersicum.
