日本蚕茧和生丝生产 根据日本农林水产省1994年12月22日的统计,日本1994年的蚕茧产量为7,724吨,比前一年下降31％。此外,养蚕农家减少到19,030户,比1993年下降30％。这种情况是由于生产方面的结构问题引起的,如养蚕户年龄老化、后继乏人,以及生丝价格低造成的。 除此之外,不正常的气候条件,早秋和晚秋气候太热太干燥,导致桑叶质量差、饲养期短,也是造成这种情况的原因。1994年前11个月的生丝产量减少到59,686件(3,581吨),比上一年同期下降8％。
Japanese cocoon production and raw silk production According to the statistics of the Ministry of Agriculture, Forestry, and Fisheries of Japan dated December 22, 1994, Japan’s cocoon production in 1994 was 7,724 tons, a decrease of 31% from the previous year. In addition, the number of sericulture farmers decreased to 19,030, a decrease of 30% from 1993. This situation is caused by structural problems in production, such as ageing of the seri- ous cultivators, lack of successors, and low prices of raw silk. In addition, due to abnormal climatic conditions, the early and late autumn climates are too hot and dry, which results in poor quality of mulberry leaves and a short feeding period. This is also the reason for this. In the first 11 months of 1994, the production of raw silk decreased to 59,686 (3,581 tons), a decrease of 8% from the same period of the previous year.
