在日本出圃苗木的起苗作业,一般用石川式切根机进行。但由于用一把刀在粘壤土的苗圃地作业,苗木和土的分离不好,所以在起苗时,其苗木须根损伤较多。另外,由于起苗作业季节性强、时间短,所以苗圃作业任务繁重,工人劳动效率很低。为此,日本旭川营林分局深川营林署秩文别苗圃对石川式切根机进行了改进,并荣获日本林业技术协会奖。 Nursery seedlings in Japan from the seedling operations, generally Ishikawa-type cutting machine. However, the use of a knife in clay nursery soil operations, seedlings and soil separation is not good, so when the seedling, the seedling fibrous roots more damage. In addition, due to the seasonal strong seedling operations, time is short, nursery homework heavy workload, labor efficiency is very low. To this end, Asahikawa Yinglin Branch of the Department of Fuchuanglinlin rank Wen-bing nursery Ishikawa cutting machine was improved and won the Japan Forestry Technology Association Award.
