摘要
以青葱、不结球白菜和小麦为填闲作物,采用盆栽方式,设置了常规休闲(CK)、冬季休闲期填闲青葱(QC)、冬季休闲期填闲不结球白菜(YC)和夏季休闲期填闲小麦(XM)4种处理方法对7年连作黄瓜土壤进行处理,研究不同填闲模式对黄瓜生长、单株产量及土壤化学性质的影响,以期为创造良好的生态环境及选择适宜的种植制度提供依据和支撑。结果表明:与常规休闲(CK)相比,小麦填闲(XM)显著提高了黄瓜的株高,青葱处理(QC)显著提高了黄瓜茎粗,XM和YC处理黄瓜产量分别提高17.7%和16.7%;同时显著提高了土壤pH,各处理显著降低了土壤电导率(EC)和土壤铵态氮含量,其中以XM效果最显著。总之,填闲栽培模式促进了黄瓜的生长,对防控连作障碍起到了积极作用。
Scallion,oilseed rape and wheat were used as catch crops.We used the pots to plant and set up regular leisure(CK),winter leisure period catch scallions(QC),winter leisure period to fill the oilseed rape(YC)and summer leisure period to wheat cover crop(XM).7-year-old continuous cropping cucumber soil was treated with four treatments to investigate the effects of different cover modes on cucumber growth,yield per plant and soil chemical properties,with a aim to provide the basis and support for creating a good ecological environment and selecting appropriate planting systems.The results showed that compared with regular leisure(CK),wheat cover crop(XM)significantly increased the plant height of cucumber,and scallion treatment(QC)significantly increased cucumber stem diameter,while XM and YC treatment increased cucumber yield by 17.7%and 16.7%,respectively.At the same time,the soil pH was significantly increased,and the soil electrical conductivity(EC)and soil available nitrogen content were significantly reduced by each treatment,and the XM effect was the most significant.Overall,the cover mode promoted the growth of cucumber and played a positive role in preventing and controlling continuous cropping obstacles.
