Hime-makura watermelon is a small ball variety with a cute oval shape, dark green skin, and thick, distinct stripes. In addition, it has excellent crunchiness, and the pulp is firmer than the conventional small ball watermelon, and it seems to have a strong crunchiness similar to that of a large ball. It has a high sugar content and a good taste, and it seems to have a characteristic that the sugar content is very high and stabilizes at 12-13 degrees. It has excellent transportability, and the outer skin is as thin as 4 to 5 mm. It can be cultivated in the summer and during the high temperature period, and because it has a firm flesh, it seems that it can be cultivated in July and August, which was difficult to cultivate because the flesh of small ball watermelons was soft.
In 1967, Choshi watermelon was designated as a crop to replace sweet potato as part of the Chiba prefecture’s horticultural promotion production area development project. At that time, mainly ‘Shima-Oh watermelon’, it expanded the planted area by shipping early and targeting the middle of the Tohoku region, and it seems that at one time it was one of the leading production areas in the prefecture with 450 ha (1111.95 ac). The city is located at the easternmost point of the Kanto region and is surrounded by the sea. It has an oceanic climate that is unusually cool in the summer and warm in the winter for a city in the plains of the Kanto region. The average annual temperature is 15.7℃, and the lowest temperature exceeds 2.4℃ even in the cold season, so it seems to be a mild climate in winter. There is a large temperature difference in winter between the coastal and inland areas of the city, and in the eastern part of the coastal area, spring cabbage is actively cultivated, taking advantage of the warm winter climate, while in the western part of the inland area, Japanese white It seems that they mainly cultivate raddish. The terrain consists of the lowlands along the Tone River and the Hokuso plateau, and the soil is covered with the Kanto loam layer. Paddy fields spread out along the Tone River and the valleys between the mountains of the plateau, and fields are formed on flat plateaus. As an area suitable for agricultural work, it supports Japan’s primary industry together with farmers.
According to the farmers, the most difficult task in managing watermelon cultivation is the work of the side branches. In order to ensure that the vines that have good attachments are well nourished, the vines that grow like a maze are traced one by one and the branches are removed. By winding the vine into a loop; This seems to produce excellent produce with consistent taste. I work carefully one by one while bending down.
