| Abstract: Cauliflower is one of the main vegetables in western Liaoning province, which has a large
open field cultivation area, but there are some unreasonable phenomena in cultivation management,
especially in fertilization management. In view of the problem of fertilization, the reasonable fertilization
method was expounded from different aspects, such as seedling raising, land preparation, planting and
growth period. According to the condition of soil nutrient and the law of fertilizer requirement of cauliflower,
the fertilization methods at different growth stages were put forward, including appropriate seedling
cultivating fertilizer, enough base fertilizer, less transplanting fertilizer, topdressing fertilizer at different
growth stages, foliar spraying fertilizer and so on. Through reasonable fertilization, yield of cauliflower
could increase 686.8 kg per 667 m2
, output value of 1 098.88 yuan per 667 m2
, the net income of 988.88 yuan
per 667 m2
, and achieving the purpose of combining land use and land maintenance together, balancing soil
nutrients, avoiding single application of chemical fertilizer and excessing application of nitrogen fertilizer,
solving the farmers' blindness and randomness of fertilization, reducing environmental pollution, improving
the utilization rate of fertilizer and realizing fertilizer control and efficiency increase. |
