Comprehensive tobacco fertilization of Red Sun Preliminary Study on mathematical model

Nitrogen and potassium are complementary,[link widoczny dla zalogowanych], that is,[link widoczny dla zalogowanych], high chloride,[link widoczny dla zalogowanych], low potassium and low nitrogen,[link widoczny dla zalogowanych], high potassium can achieve the same effect of the economic benefits of optimal use of 2.4-fertilization programs to the economic benefits created by the regression equation as the objective function,[link widoczny dla zalogowanych], applications for computer Best fertilization program. In a 1.682 ~ <X ≤ 1.682 range, take steps of 0.42, the total of 9. = 729 fertilization program, which is relatively high economic returns and stable economic benefits in the program is 620 yuan per mu of programs between ~ 645 yuan, a total of 5O months, we find that the high economic benefits within the fertilization program feasible. 5O a program of the application, x the frequency distribution in Table 4. In combinations on, mostly to the 95% CI x threshold value range as the optimal combination, but this generally very narrow range of calculated, and its credibility is also frequency distribution of chest face relatively large changes occur, so actual production often have a certain bias. To this end, we integrated a frequency distribution table, effect analysis and the maximum economic benefits, / z. / Frederick O: r Figure I Figure 3, and several other aspects of fertilization program x to determine the optimal group profile option. (1) From Table 4 shows that in high economic benefits program, x focus o. 84 ~ 1.68 range (total 88), x is more uniform, x of the distribution, although not very concentrated, but the trend of taking a large value, (2) Effect of 2 from the barrier is legal, etc.: Comprehensive tobacco drying red Taiwan fertilization Preliminary Study on mathematical model of delicate 4X.

Based on the above results, we x 'by 0.1, plus 0.34-coding units to x reduction.
