近年来,黄瓜已成为我市保护地蔬菜栽培中较为重要的一类蔬菜。但据植保站调查,大棚黄瓜春季化瓜现象比较严重,致使黄瓜产量降低,直接影响瓜农的经济效益,分析其原因,主要有以下几点:一、品种结实能力差引起的化瓜一般春黄瓜生育期短,生长势弱,化瓜现象比较严重;而夏黄瓜和秋黄瓜多为中晚期品种,生长势强,化瓜率低。上述情况,可通过人工授粉的方法,使瓜条得以继续生长。此外,不同的季节、不同的栽培方式、选用不同的品种,也可降低化瓜率。
In recent years, cucumber has become the city’s protected vegetable cultivation more important type of vegetables. However, according to plant protection station survey, greenhouse cucumbers spring melon phenomenon is more serious, resulting in reduced cucumber production, a direct impact on the economic benefits of melon farmers, analysis of the reasons, mainly in the following points: First, the variety of poor fruiting capacity caused by melon general spring cucumber Short growth period, weak growth, melon phenomenon is more serious; and summer cucumber and autumn cucumber are mostly late varieties, strong growth potential, melon rate is low. The above situation can be achieved by artificial pollination, the melon can continue to grow. In addition, different seasons, different cultivation methods, choose different varieties, but also reduce the rate of melon.
