钾钙配施对番茄产量和品质的影响
Effects of Combined Application of Potassium and Calcium on Yield and Quality of Tomato
摘要
Abstract
Tomato'Liaofen 185'was used as the test material,and the pot experiment method was used to set up eight fertilization treatments,included lime dosage 0 g·kg-1 soil+K2O 0 g·kg-1 soil,lime dosage 0 g·kg-1 soil+K2O 0.11 g·kg-1 soil,lime dosage 0 g·kg-1 soil+K2O0.22 g·kg-1 soil,lime dosage 0 g·kg-1 soil+K2O 0.44 g·kg-1 soil,lime dosage 0.5 g·kg-1 soil+K2O 0 g·kg-1 soil,lime dosage 0.5 g·kg-1 soil+K2O 0.11 g·kg-1 soil,lime dosage 0.5 g·kg-1 soil+K2O 0.22 g·kg-1 soil,lime dosage 0.5 g·kg-1 soil.The effects of potassium and calcium fertilizers on the yield and quality of tomato were studied,in order to provide references for the application of potassium and calcium fertilizers in facility tomato production.The results showed that the application of potassium fertilizer could increase tomato yield,and when the amount of potassium fertilizer reached a certain amount(K2O 0.22,0.44 g·kg-1 soil),the application of calcium fertilizer significantly increased tomato yield.The content of soluble solids increased with the increase of the amount of potassium fertilizer.When the amount of potassium fertilizer reached a certain amount(K2O 0.22,0.44 g·kg-1 soil),the application of calcium fertilizer significantly increased the content of soluble solids.Without calcium fertilizer,when the amount of potassium fertilizer reached a certain amount(K2O 0.44 g·kg-1 soil),the vitamin C content could be significantly increased.In the case of calcium fertilizer,low potassium fertilizer(K2O 0.11 g·kg-1 soil)could significantly increase the vitamin C content of tomato.Under the same amount of potassium fertilizer,the soluble sugar content of tomato with calcium fertilizer increased significantly.Appropriate potassium fertilizer combined with calcium fertilizer was beneficial to improve the sugar acid ratio of tomato.When the amount of potassium fertilizer reached a certain amount(K2O 0.22,0.44 g·kg-1 soil),the sugar-acid ratio of calcium fertilizer tomato was significantly increased to 16.40 and 15.67.The comprehensive evaluation of each index by principal component analysis showed that K2 O 0.44 g·kg-1 soil combined with lime 0.5 g·kg-1 soil could better promote the improvement of tomato yield and quality.关键词
