一、日本插秧机的发展动向1978年日本水稻种植面积246.8万公顷,机插面积已达85.5%。两行、四行插秧机保有量达160万台。近年来水稻种植面积稍有减少,但插秧机的使用台数却有所增加。1979年北海道地区机插面积已达92.1%。从育苗方式看,1976年以来,小苗逐渐减少,中苗增加很快,故在插秧机品种上也随之出现小苗、中苗通用的插秧机。从普及台数看,以手扶插秧机为主,两、四行的占总数的70%。但和1978年比,
First, the development trend of Japanese rice transplanter In 1978 Japan’s rice planting area of 246.8 hectares, machine area has reached 85.5%. Two lines, four lines of rice transplanter holdings of 1.6 million units. In recent years, the area under rice cultivation has decreased slightly, but the number of transplanter used has increased. In 1979 Hokkaido machine area has reached 92.1%. From the nursery perspective, since 1976, the gradual reduction of seedlings, seedlings increased rapidly, it also appears in the transplanter varieties of seedlings, seedling universal transplanter. From the popularization of Taiwan to see, hand-held rice transplanter-based, two or four lines accounted for 70% of the total. However, compared with 1978,
