摘要
以光辉201番茄为材料,研究2种不同性质钙肥施用对酸碱度不同的土壤条件下番茄产量及品质的影响。试验结果表明,番茄定植时施用石膏粉(15 kg/667 m2)和石灰粉(25 kg/667 m2)均可显著降低脐腐病发病率,显著提高产量。在弱碱性土壤中,施用石膏粉处理最好,与施用石灰粉处理相比,番茄脐腐病发病率显著降低,产量显著提高;在弱酸性土壤中可以施用石灰粉和石膏粉,其中以施用石灰粉的处理效果较好。
Taking Guanghui 201 as material, we studied the effects of two different properties of calcium fertilizer on tomato growth under different soil pH conditions. The results showed that, using land plaster （15 kg/667 m^2） or pulverized lime （25 kg/667 m^2） could significantly reduce the incidence of blossom-end rot, and significantly improve yield. In weak alkaline soils, treated with land plaster was better compared with pulverized lime, it could significantly reduce the inci-dence of blossom-end rot, and significantly improve yield. In weak acid soils, we could use land plaster or pulverized lime, and the application of pulverized lime was better.
