| This paper studied the effects of different fertilizer models on simulation for the '3414'fertilizer experiments in 2009～2010, which the Capsicum cultivated by Tropical Crops Genetic Resources Institute of the Chinese Academy of Tropical Agricultural Sciences. The results showed that.(1) Through use of different weights of nitrogen, the results showed that there was a significant difference at the 0.05 or 0.01 probability levels in the yield between the treatments. And the average yield of treatment 6, reached a maximum of 12.1 t·hm-2. The average yield of treatment 1, reached a minimum of 1.4 t·hm-2.(2) The fertilizer consumption and production as a test factor, the equations for the three-factors obtained by fitting the equation y= 1243.057+17.806x1+29.047x2+ 28.962x3-0.078x12-0.623x22-0.056x32+0.24x1x2+0.09x2x3+0.017x1x3, this equation F<0.0001, the effect was extremely significant. According to this equation Solver, the received the largest NPK fertilizer were 339.86,118.03,405.02 kg·hm-2.we found that the order of the interaction of fertilizer NP> PK> NK, and all for the positive effect. These show that the interaction of NP play a major role, followed by PK, and finally for the NK.(3) The analysis of nitrogen, phosphorus, potassium single factor, two-factor interaction, and the interaction of three factors, the results show that the interaction between NPK effects is obvious, nitrogen fertilizer from 114.141 to 213.177, and then to 339.86 kg·hm-2, phosphate Fertilizer from 23.312 to 44.578～64.374, and then to 118.03 kg·hm-2, potash fertilizer from 258.589 to 294.411, and then to 405.02 kg·hm-2.(4) Using one-factor when the fertilizer model was fitted to treatments 2,3,6,11 to N fertilizer fitting, to treatments 4,5,6,7 fit for P fertilizer effect, to treatments 6,8,9,10 to K Fertilizer fitting. Linear plus plateau and Square root were Pr>F values are not reached significant levels, they were not calculated the recommended fertilizer.(5) Vitamin C and pepper weight relationship between the significant correlations. Maximum content of vitamin C was treatment 6, which is the maximum weight of pepper production process the same was treatment 6. Therefore, vitamin C, the maximum weight of fertilizer can determine the maximum amount of fertilizer. Vitamin C, the largest NPK fertilizer were 345.0 kg·hm-2,113.850 kg·hm-2,414 kg·hm-2.(6) three-factors and three of one-factor of the equation on the comparison, according to equation Pr＜F value judgments come, only three-factors and one-factor can calculate the fertilizer recommendation. Finally, the largest NPK fertilizer were 332.35～339.86,117.84 ～118.03,396.77～405.02 kg·hm-2. Then pepper production in the 11.85～12.08 t·hm-2.Taking into account the quality of vitamin C, NPK largest fertilizer were 345.0, 113.850,414 kg·hm-2, and treatment 6 in the fertilizer use efficiency in the handling of fertilizer usage. The adjusted maximum of NPK fertilizer were 332.35～345.00 kg·hm-2, 113.85～118.03 kg·hm-2,396.77～414.00 kg·hm-2.Three-factors and three of one-factor compare the effectiveness of fertilizer, NPK fertilizer best defined as 311.78～332.35 kg·hm-2,108.35～117.84 kg·hm-2,371.73 396.77 kg·hm-2, and economic benefits in 35610～41310 Yuan·hm-2.(7) The analysis of NPK nutrient utilization for multiple comparisons, the high and low fertilizer use efficiency of each treatment arranged in order, the highest value was treatment 6. N, P, K fertilizer use efficiency were 33.23%,13.97%,42.81%.(4) In the verification test, the block 1, the recommended fertilizer application rates and conventional difference between the yield significantly, an increase of 15.39%. Block 2, and conventional fertilizer recommendation was no significant difference between fertilization, may be due to a block 2 repeat with the other two yield gap between the great weakening of the recommended fertilization and yield differences between conventional fertilization. Block 2 on the increase rate was 20%. Inα= 0.05, the block 3 of 3 treatment significantly different from each other, and block 3 output rate of 17.31%. |
