设计简介
摘要：油菜是我国优势农作物，长江流域是我国油菜主产区和优势产业带，油菜面
积占我国油菜总面积的85%左右。据农业部2007年底统计，湖南省冬种油菜面积1459万亩。
而冬季可种植油菜的总面积高达3000多万亩，发展油菜潜力巨大。由于我国移栽机械发展缓
慢，秧苗移栽几乎全部由人工完成，劳动强度大、生产效率低、栽植质量差、生产成本高。
因此，实现油菜移栽机械化已成为农业生产的迫切需要。随着钵体育苗技术的日趋完善，钵
苗栽植技术在国内外被广泛应用。

Abstract:Rape is one of a superior crop in China, the Yangtze river basin is a main
producing area and advantageous belt of rape, which planting area is about 85% of the total area in
China. From the statistics of agriculture ministry in the end of 2007, the area for winter planting
rape is 14.59 million mu in Hunan province, and the area suit for winter planting rape can reach up
to 30.00 million mu , which reveal a large potential in the rape industry. The development of
transplant machine is slowly in China, so the transplant of seedling is almost all completed by
artificial, which high in labor intensity and production costs but low in production efficiency and
transplanting quality. Therefore, to realize mechanization of the rape-transplant is in a hurry for
agricultural production. The bowl seeding planting technology is widely used in the domestic and
overseas with the gradually maturing bowl seeding technology.
Key words:ransplant, mechanization, bowl seeding , rape
