摘要
采用正交试验设计对多元枣树专用叶面肥最佳配方进行了试验研究。对单株产量和单果重的分析结果表明 :配方中各因子对单株产量影响的大小依次为 N>PPA>Zn>P>B,对单果重影响的大小依次为 N>PPA>B>Zn>P;N90 与 N1 80 、PPA5与 PPA1 0 的增产效应的差异达极显著水平 ,总产量 N90 较 N1 80 提高 2 4.5 % ,PPA1 0 较 PPA5提高 9.7% ;膨果效应 N90 与 N1 80 、PPA5与 PPA1 0 的差异达极显著水平 ,B1 2 与 B2 4的差异达显著水平 ,其中单果重 N1 80 比 N90 高 8.1% ,PPA1 0 比 PPA5高 6 .6 % ,B1 2 比 B2 4高 4.5 %。据此通过综合评价和成本分析 ,确定枣树专用叶面肥最佳配方为 N90 P45B1 2 Zn1 5PPA1 0 。
Optimum recipe of special multi element foliage fertilizer for jujube tree is tested and studied by adopting orthogonal trial design.Analysis of the test indexes of single tree yields and single date weights shows that the effect of the factors in tested recipes on single tree yield is N>PPA>Zn>P>B in turn,and the effect on single date weight is N>PPA>B>Zn>P;differences in yield increments between N 90 and N 180 ,PPA 5 and PPA 10 are extremely marked among the factors;total yield of N 90 is 24.5% higher than that of N 180 and total yield of PPA 10 ,9.7% higher than that of PPA 5;differences in enlarging date fruit between N 90 and N 180 ,PPA 5 and PPA 10 are extremely marked,and that between B 12 and B 24 is marked;among them,single date weight of N 180 is 8.1% higher than that of N 90 ,PPA 10 s single date weight is 6.6% higher than PPA 5s and B 12 s is 4.5% higher than B 24 s.Based on the analyses mentioned above,N 90 P 45 B 12 Zn 15 PPA 10 is determined as the optimized recipe of special foliage fertilizer for jujube tree through integrated evaluations and cost analyses.
