Abstract The planting-board is a kind of material that can produce vegetables by directly watering
after the seeds and cultivation medium are mixed，compressed and dried．This planting-board can be
coupled with water storage container to form a new system for vegetable cultivation on balcony．Taking the
pakchoi‘Xiawang’as material，this paper studied the effects of manufacture proposal of planting-board and
drying temperature on seed germination of pakchoi by orthogonal test and multi-index comprehensive grading
method．The results showed that the differences of comprehensive grading between different levels of waterretaining
agent and drying temperature were significant or extreme significant．The optimal manufacture
proposal for pakchoi planting-board was taking 4% volume of water-retaining agent，30% volume of
vermiculite，mixing them with matrix，and drying temperature at 45 ℃．
