Using some cover crops in vegetable production is expected that it can be beneficial to the cultivation such as reduction of erosion or splashing by covering the soil surface, weed control by shading sunshine or allelopathy, enrich ecological diversity by securing hangout for insects and nitrogen fixation or catching of surplus nutrition. And in cultivation under the living mulch with minimal tillage, the application of basal fertilizer is very important. In the shaft tillage cultivation that was devised by authors, these application method is influential elements for the growth of crops cause of competition of nutrition with weeds and salt injury at taking root.
In this report, a tool for shaft tillage cultivation equipping with injector of paste type fertilizer, which enable to simultaneous operation of tilling and fertilizing, was tested on trans-planting cultivation using of Chinese cabbage plug seedling. The results were as follows:
1) Tool for shaft tillage cultivation equipping with injector of paste type fertilizer was usefulness in simultaneous operation of tilling and fertilizing, but the fertilizer was overflowed without penetrating into the soil under the certain soil conditions. And the growth of some seedlings were influenced.
2) Since the growth of seedlings under the condition of solid type fertilizer with surface broadcasted application, it were suggested that there is no difference in competition of fertilizer between applications of surface broadcasting and under seedling penetration.
3) The differences of the seedlings' growths were clearly appeared the 2nd day from transplanting.
