密度和施肥量对辣椒新品系ZJ1-12产量和经济效益的影响

为探索辣椒新品系ZJ1-12的高产优化农艺措施,运用4因素(完全实施)5水平的二次正交旋转回归设计研究了密度、氮、磷、钾肥对辣椒新品系ZJ1-12产量和经济效益的影响。结果表明:各因子表现正向增加作用,作用大小排序为密度>K20>N>P2O5肥用量。单产达156.93kg/667m2以上的优化农艺措施为密度10235～10813株/667m2,纯N量13.525～14.855kg/667m2,P2O58.232～9.748kg/667m2,K2010.875～12.6kg/667m2。当最高产量为278.84kg/667m2时,纯收益高达4149.04元/667m2。

Effects of Planting Density and Fertilization Rate on Fruit Yield and Economic Profit of New Hot Pepper Strain ZJ1-12

In order to optimize the high-yield agrotechniques for new hot pepper strain ZJ1-12, the 4-factor 5- level quadratic orthogonal rotational regression design was used to determine whether the planting density, N, P and K fertilizers influence the fruit yield and economic profit of the ZJ1-12 in this study. The result indicated that each of all the factors played a positive role in increasing the yield, which showed the planting density〉KzO〉N〉 P205 in effective order. The yield was to reach over 156.93 kg per 667 m2 if the planting density was 10 235 - 10 813 plants per 667 m2, the fertilization rate of pure N was 13.525 - 14.855 kg per 667 m2, P205 8.232 - 9.748 kg per 667 m2 and K20 10.875- 12.6 kg per 667 m2. The highest yield of 278.84 kg per 667 m2 got the net income of 4 1＇49.04 RMB yuan per 667 m2.
