蔬菜机械化育苗的现状与展望

机械化育苗,美因称它为塞子苗生产。近年来这项农业栽培技术在世界上有了迅速发展,当前美国移栽蔬菜中大约70％采用塞子苗。机械化育苗主要设备是精量播种生产线,与传统的土方育苗和裸根育苗相比较,其优点是:省时、省工、成苗率高、作物长势整齐、便于机械化移栽等。北京花乡育苗场是我国第一座专门提供商品塞子苗的场家,其销售量逐年增多,1990年已达500多万株。我国农民习惯栽植大苗,尽管用户认为塞子苗偏小些,但由于这种育苗方式优点很多,农民愿意接受。

The Current Situation and the Future Prospect of Mechanized Seedling Production System of Vegetable Crops

Mechanized seedling production system is called Plug Production System or Speedling System in western countries, such techniculture system has been quickly progressed in recent years in the whole world. This is reflected in fact that 70 percent Vegetable transplants is plug plants fo be.adopted in u.S.The main equipment of mechanized seedling growing system is the precision sowing line The seed is covered with peat and vermiculite.Peat and vermiculite are the good plug seedling growing medium. The system provides several advantages. They are not found in current blockraise seedling and bare root seedling processes. Time to grow the crop and labor to transplant are both reduced by sowing the seed in the plug tray. Plug seedlings will grow 100% very uniform plants.Mechanized seedling production system of vegetable crops has just started in china. Huaxiang nursery is the firs tone to provide the plug seedlings on the market in china. Huaxiang nursery delivered more than s million plug seedlings to vegetable farmers in 1990. As the Chinese grower desire a slightly large plants, tomatoes and eggplants mostly are sown in 72 cell per tray, peppers and cabbages are sown in 128 cell, celery is sown in 200 cell. The plug plants had become an accepted practice by the Beijing vegetable growers. Althongh some of the customers complain that the seedlings are a little small.
