Abstract: In order to find out the fitting planting density and fertilization level which could lead the alpine anti-season cauliflower to a high yield , I had investigated the effect ,basing on the four kinds of planting density and fertilization level , on the yield of the cauliflower . The result of this research told us that there were some distinct differences in the four kinds of planting density, and so was in the four kinds of fertilization level . The perfect planting density would be 2400 individual plant per 667 square meters . And the perfect fertilization level would be 78 kilogram per 667 square meters . Furthermore , there were also distinct differences in the mutual planting way basing on the above two factors .The optimal combination would be 2400 individual plant per 667 square meters of the planting density and 78 kilogram per 667 square meters of the fertilization level.
