| 摘 要： | 以“京番301”番茄为试验材料,采用土壤限根栽培方式,以CaO施入量0(T1)、300(T2)、600(T3)、900(T4)、1200(T5)kg·hm-2设置5个处理,以不施入任何肥料为对照(CK),研究不同施钙量对番茄果实品质、产量及养分含量的影响,以期为钙肥的高效合理利用和高品质番茄的生产提供参考。结果表明:钙肥的施入降低植株株高、茎粗和叶面积,但可以提高叶片叶绿素含量。钙肥有利于改善果实的营养品质,T4处理可溶性固形物和可溶性总糖含量最高,显著高于其它各处理,比T1处理分别提高了24.4%和62.3%。T1处理平均单果质量、小区产量和单位面积产量较大,钙肥的增产作用在试验中表现不明显。各养分在一定的钙肥范围内,随钙肥的增加而增加。综合分析,T4处理果实营养品质较好,T1处理产量较高。

| Abstract: | ‘Jingfan No. 301’was used as experimental material to study the effects of different calcium application on tomato quality, yield and nutrient content. The experiment was adopted soil root restriction cultivation, and CaO application was set five treatments, 0 (T1), 300 ( T2), 600 ( T3 ), 900 (T4), 1 200 (T5) kg ? hm 2 ,no fertilizer as control(CK). The results showed that the application of calcium fertilizer reduced plant height, stem diameter and leaf area, but increased leaf chlorophyll content. The application of calcium fertilizer was beneficial to improve the nutritional quality of fruits. The contents of soluble solids and total soluble sugar of T4 treatment was the highest, significantly higher than other treatments, and increased respectively by 24. 4% and 62? 3% compared with T1 treatment. The average single fruit weight, community yield and yield per 1 hm2 of T1 treatment were larger,and the effect of calcium fertilizer on increasing yield was not obvious in the experiment. Each nutrient increased with the increase of calcium fertilizer in a certain range of calcium fertilizer. Comprehensive analysis showed that T4 treatment had better nutritional quality,and T1 treatment had higher yield. |
