The Impact of the Fertilization Formula “3414”on the Quality and Product After Planting of the Greenhouse

摘要

The relation between the fertilizer that N, P and K fertilizer applied and the angelica output has to be studied when the Angelica is transplanted and seedlinged to build the transplanting fertilization model from the greenhouse to the field. the Soil Testing Formula “3414” for seedling angelicain the greenhouse was carried out in Tanchang County, along with a series of statistical analysis for the different ratio of the fertilizer, growth and development situation, production and bolting rate, etc. And initially set up the equation of the fertilizer function model that are Angelica N, P, K as following: Y=1638.71-4.99X1+17.92X2+24.64X3-0.65x12-0.84X22+ 0.82X32+2.10X1X2+0.22X1X3-4.84X2X3. It is ensured that the product of seedling transplantation reached to the maximum 1932.52kg/hm2 so that to have won the best fertilizer rate of N: 81.15kg/hm2, P2O5: 80.67 kg/hm2, and K2O:29.78 kg/hm2.
