Abstract:Abstract: To improve productivity, reduce labor intensity and lower production costs, the Netherlands had been developing precision seeding production line, grafting production line, seedlings production line with stone wool blocks and supporting equipments in vegetable seedlings production. After precision seeding production lines having been widely used for vegetable seedlings production, grafting production line for vegetables has been used to make grafting productivity increase by 50% or more, and seedlings production line with stone wool blocks for vegetables has been used to make transplanting productivity reach up to 7500-1 2000 seedlings per hour. In addition by learning from flowers automated production technologies in vegetable seedlings production, several of transporting equipments of production materials have been developed and widely used such as laying cart of stone wool blocks, trays conveyor belts, human hydraulic vehicle and so on, so as to achieve labor saving production and enhance production efficiency and market competitiveness. This paper introduces a production process of cucumber seedlings using seedlings production line with stone wool blocks and a production process of tomato seedlings grafted with precision seeding production line,grafting production line,and seedlings production line for using stone wool blocks. The operating productivities and manufactories of these production lines are discussed. Based on the above discussion, the greenhouse vegetable seedlings production of the Netherlands has the following characteristics: a) Because of the advantages of high porosity and reducing bacteria for stone wool, and the advantages of convenient operation and water-saving irrigation with tidal, hydroponic with stone wool blocks and tidal irrigation have been widely applied in greenhouse seedlings production; b) Because flower growers invested much more funds on the development of automated production technologies than vegetable growers,the level of flowers automated production is higher than that of vegetables. Many operations and transporting of production materials in vegetable seedlings production need to be done by manpower, and production line for vegetable seedlings is relatively short and not complete; c) The equipment system of vegetable seedlings production is usually composed of precision seeding production line,grafting production line and seedlings production line with stone wool blocks. Being combined with automated equipments and manual operation reasonably, production line would become an effective and easy way to reduce labor demand and enhance productivity; d) It is an important way to develop internal transporting equipment of production materials for reducing labor intensive and increase operating speed. Greenhouse vegetable seedlings production in China is facing labor shortages, low level of production automation, and low productivity. According to the Chinese vegetable seedlings production condition and learning the development experience of horticultural automated production technology in Netherlands, China should focus on developing vegetable seedlings production lines and transporting equipments of production materials to reduce labor demand, enhance productivity, and promote a modern transformation of the Chinese horticultural production.
