摘　　要：研究覆施不同稻壳量对大棚黄瓜团棵期、盛花期、初果期、盛果期和末果期的长势影响及防控黄瓜疫病的效果。在覆施不同稻壳量后,分别测定黄瓜在每个生长期的土壤温度、棚内相对湿度、株高和茎粗、根系干重和根系活力及黄瓜疫病病情指数等指标。结果表明,与对照相比,覆施25 kg稻壳对大棚黄瓜15 cm处的土壤温度效果最好,且盛果期的温度增幅最快;棚内相对湿度显著下降;黄瓜株高、茎粗、根系干重和根系活力等指标明显提高,黄瓜疫病发生程度显著减轻,以覆施25 kg稻壳处理时黄瓜长势及抗病性最显著,提高了黄瓜产量。该方法成本低、易操作,节时省力,若因地制宜,适量施用,将对保护地黄瓜无公害栽培具有重要作用。To study the influence of different rice hull amount on the growth of cucumber at stage of rosette,full bloom,early fruit,full fruit and last fruit in greenhouse and the prevention and control of cucumber blight,soil temperature,relative humidity,plant height,stem diameter,root dry weight,root activity and disease index of cucumber during each growing period were determined by covering different rice husk amount.The results showed that compared with the control,covering 25 kg rice husk had the best effect on soil temperature at 15 cm of cucumber in greenhouse,and the temperature increased fastest at full bloom stage.The relative humidity in the shed decreased significantly.The plant height,stem diameter,root dry weight and root activity of cucumber were significantly increased,while the disease index of cucumber phytophthora blight was significantly decreased.The method was low cost,easy to operate,time saving and labor saving.If applied appropriately according to local conditions,it will play an important role in pollution-free cucumber cultivation in protected areas.
