钾钙配施对番茄产量和品质的影响OA
Effects of Combined Application of Potassium and Calcium on Yield and Quality of Tomato
以番茄"辽粉185"为试材,采用盆栽试验法,研究了钾钙配施对番茄产量、品质的影响,以期为钾钙肥在设施番茄生产上的应用提供参考依据.结果表明:施用钾肥能提高番茄产量,且钾肥达到一定用量时(K2O 0.22、0.44 g·kg-1 土),配施钙肥显著增加番茄产量.可溶性固形物含量随着钾肥用量的增加有增加的趋势,在钾肥达到一定用量时(K2O 0.22、0.44 g·kg-1 土),配施钙肥显著增加可溶性固形物含量.不施钙肥时,钾肥用量达到一定数量时(K2O 0.44 g·kg-1 土)才能显著提高番茄维生素C含量.在配施钙肥的情况下,低量钾肥(K2O 0.11 g·kg-1 土)就能显著提升番茄维生素C含量.可溶性糖含量、糖酸比均随着钾肥用量的增加有增加的趋势.在钾肥施用量相同的情况下,配施钙肥番茄可溶性糖含量明显增加.适宜的钾肥配施钙肥有利于提高番茄的糖酸比.钾肥达到一定用量时(K2O 0.22、0.44 g·kg-1 土)施用钙肥番茄糖酸比明显提高,达到16.40和15.67.采用主成分分析对各项指标进行综合评价表明,K2O0.44 g·kg-1 土配施生石灰0.50 g·kg-1土能更好的促进番茄产量和品质的提高.
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.
