| Abstract: | Four-factor and five-level regression rotation design was used to study the relationship between different planting density and amount of fertilizer(N,P,K) of Longhua 243 yield.The optimization mathematical models of various factors and yield index was established,that is,Y=4200+420X1+288.75X2+105X3+175X4-144.6875X12-221.5625X22-253.4375X32-165.3125X42+174.375X1X2+20.625X1X3+52.5X1X4+58.125X2X3+41.25X2X4-7.5X3X4.The optimization schemes of high-yield Longhua 243(higher than 3676.67 kg/hm2) was established: ... |
