利用冬暖大棚(日光温室)进行黄瓜越冬栽培在山东省已有十几年的历史,全省栽培面积达到50万亩以上,亩产量平均7500 kg上下,但省内各地差异较大。寿光市五台镇方奎祥自1994年以来,连续五年亩产达到20000 kg以上,1997年创下亩产30000 kg的高产纪录。然而,省内还有相当一部分冬暖大棚亩产量还不到5000 kg。因此,如何提高亩产量,增加单位面积效益是山东黄瓜种植面临的主要问题。为使寿光的超高产经验上升为理论,进而指导全省各地冬季黄瓜生产,山东省农科院蔬菜所和山东农业大学园艺系联合对寿光的高产经验进行了调查测试。现将部分调研结果分析如下。
The use of winter warm greenhouse (greenhouse) cucumber winter cultivation in Shandong Province has more than 10 years of history, the province’s cultivated area reached 500000 mus of above, the average yield of 7500 kg per acre up and down, but the differences are large throughout the province. Shouguang City, Wutai Fangkui Xiang since 1994, for five consecutive years of more than 20,000 kg per mu, a record high of 30000 kg per mu in 1997. However, there is also a considerable part of the province’s winter warm shed less than 5000 kg per mu. Therefore, how to improve the yield per mu and increase the benefit per unit area are the main problems facing cucumber planting in Shandong. In order to make Shouguang super high yielding experience rise to theory, and then guide the winter cucumber production throughout the province, Shandong Academy of Agricultural Sciences and the Department of Horticulture, Shandong Agricultural University, Shouguang high-yielding joint experience of the survey were tested. Now part of the survey results are as follows.
