以江苏丘陵地区大棚草莓为对象开展大田试验,研究化肥减施配施土壤调理剂对草莓果实品质和土壤养分的影响。本试验设置5个处理,为不施化肥对照(CK)、常规量施化肥处理(F100)、化肥减施50%处理(F50)、化肥减施50%同时配施硅钙镁土壤调理剂处理(F50S1),化肥减施50%同时配施骨粉处理(F50S2)。试验结果表明,与F100处理相比,不施化肥对照(CK)和F50处理草莓单株叶片数和头茬果单果质量显著减少(P0.05),二茬果二级果果实硬度比F100处理显著提高了27.03%(P<0.05),F50S2处理能够显著延长草莓果实的货架期。综上所述,在过量施肥土壤中应适量减施化肥同时配施土壤调理剂,可以有效维持土壤养分供应,促进草莓生长发育,提高果实品质。

To the Editor： A 65-year-old woman with calcinosis, Raynaud＆#39;s phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia （CREST） syndrome was admitted to hospital because of progressive dyspnea on exertion for about 1 year. In the past, she had been diagnosed as gastroesophageal reflux disease and scleroderma for 10 years. Physical examination showed masked face, Raynaud＇s phenomenon, finger sclerodactyly, and skin telangiectasia on her neck and back [Figure 1a and 1b]. The titer of anticentromere antibody in serum increased to 1： 1000. Analysis of arterial gas on room air revealed the partial pressure of arterial oxygen （PaO2） was 54 mmHg （1 mmHg = 0.133 kPa） and carbon dioxide （PaCO2） was 32 mmHg. Echocardiogram showed severe tricuspid regurgitation and elevated pulmonary arterial pressure of 78 mmHg.
