キュウリ（胡瓜）（Cucumis sativus L.）
中国を経由し,平安時代から栽培がされていた。胡瓜の「胡」は,古代中国の異民族に対する別称。「木瓜(きうり)」「黄瓜(きうり)」熟すと,黄色くなる事から命名。It is also called "princess cucumber" in some areas.
It is harvested while it is immature and the skin is soft, so a refreshing green image is common.“Cucumbers” require a large amount of water when growing, but are vulnerable to rain.With delicate crops such as being prone to illness if the soil is over-humidified or poorly ventilated.Therefore, I hear that it is difficult to continue harvesting for a long period of time.Among them, Iwate Prefecture boasts one of the largest production volumes.Planting begins around the end of May, and the main focus is on open-field cultivation, which reaches its peak shipment period from July to August.Some producers extend the period by cultivating in unheated greenhouses（late raising;Forcing suppression cultivation）.When it is shaken by the wind, the fruit will be scratched and damaged, so it is cultivated with tunnel-shaped columns so that the fruit grows inside.The honey bees encourage pollination from flower to flower and bloom one after another, actually growing 2-3 cm a day.It is said that the fruits will be harvested twice in the morning and in the evening at the peak.The collection facility also accepts the harvest twice in the morning and at night, cools it in the pre-cooling facility, and then ships it in a cold storage car while maintaining its freshness.I'm happy to hear that shipments will continue until around October.It will be harvested about one month after the harvest. It is good to extend it well from the main branch to the child branch and grandchild branch.To get a lot of fruit, adjust to the weather and growth.Watering and after manure that do not burden the branches are important.The fruit does not cast a shadow on the leaves. Harvest the leaves and branches by diligently picking them for better ventilation.Daily management and utilization We need patience to please consumers.We overcame various difficulties such as the damage of pests and the drop in production due to unseasonable weather such as cold summer.Our joy given and enjoyed by producers is the true taste.How about going with today's “sake”? When the seasons pass, even next year.（花言葉:洒落）A toast to you who are clean and nifty!
