摘  要：
采用随机区组设计方法研究了石灰性土壤磷、钾与钙配合对保护地番茄钙吸收的影响,并利用差值法计算了钙的利用率。研究结果表明,CaP1和CaK2处理最佳,可以显著提高保护地番茄总吸钙量和果实吸钙量,提高钙的利用率;与单纯施钙处理相比,钙的利用率分别提高10 3和16 1个百分点,同时,CaP1和CaK2处理能明显改善保护地番茄生物学特性,显著提高番茄果实产量;与单施钙处理相比,番茄的果实产量分别提高了16 1%和22 9%。研究结果同时证明钙磷配合或钙钾配合施用可以提高番茄果实中Vc的含量、糖分含量,降低酸度含量和脐腐病果的数量,明显地改善果实的品质。

摘  要：
An experiment was conducted to determinate effects of P, K cooperated with Ca on Ca absorption of tomato on a calcareous soil in Greenhouse. The utilization ratio of Calcium was studied using differential method. The experimental design was random block design. Results showed that treatments of CaP_1 and CaK_2 were best among all treatments. In treatment CaP_1 and CaK_2, the quantity of total Ca absorption and Ca absorption in fruit were significantly promoted, and the utilization ratio of Calcium was improved. Comparing with the treatments of CaP_0 and CaK_0, the utilization ratio of Calcium in treatment of CaP_1 and CaK_2 increased by 10.3% and 16.1% separately. Meanwhile, biological properties of tomato was improved and the tomato fruit yield was increased markedly. The increment of yield was 16.1% and 22.9% for treatment of CaP_1 and CaK_2 respectively, comparing with the treatment of single applying Calcium. The experiment (also) indicated that CaP_1 and CaK_2 could increase Vc and sugar content in tomato fruits, reduced the acidity in tomato fruit and the quantity of the rotten fruit. We can concluded that P, K cooperated with Ca could significantly improve the (quality) of the tomato fruit.
