夏播黄瓜对解决首都八、九月份市场供应上起着重要作用,播种面积在万亩以上。但由于气候条件的影响,这茬黄瓜的单产水平一直比较低,全郊区的亩产水平还不足2000斤。为了鼓励多种,种好夏播黄瓜,近年来,市人民政府采取了加价补贴的经济手段,使夏播黄瓜的种植面积能够稳定并有所增长。京郊一些社队为了确保八、九月份黄瓜供应,还把夏播黄瓜播种在塑料大棚里,采用这种保护栽培措施,产量水平有了一定幅度提高,但经济效益低,没有实际推广意义。在分析了造成夏播黄瓜低产的内在因素和外界环境条件影响之后,确定了采用薄膜地面覆盖这项栽培技术。
Summer cucumber cucumber to address the capital market in August and September plays an important role in the sown area of more than mu. However, due to the impact of climatic conditions, the yield level of cucumber has been relatively low, and the output per mu in the entire suburbs is still less than 2,000 kg. In order to encourage a variety of summer sowing cucumbers, in recent years, the Municipal People’s Government has taken the economic means of raising subsidies so that the planting area of summer sowing cucumbers can be stabilized and increased. In order to ensure the supply of cucumbers in August and September, some communes and sub-communities in the suburbs of Beijing have sowed summer sowing cucumbers in plastic greenhouses. With this protection and cultivation measures, the output level has been increased to a certain extent, but with low economic benefits and no practical promotion significance. After analyzing the internal factors causing the low yield of summer sowing cucumber and the influence of external environmental conditions, the cultivation technique using film ground cover was determined.
