| 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N180、PPA10的增产效应的差异达极显著水平，总产量N90较N180提高24.5N，PPA10较PPA5提高9.7％；膨果效应N90与N180、PPA5与PPA10的差异达极显著水平，B12与B24的差异达显著水平，其中单果重N180比N90高8.1％，PPA10比PPA5高6.6％，B12比B24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N90P45B12Zn15PPA10。 |

| Abstract: |
| Optimum recipe of special multi-element foliage fertilizer for jujube tree is tested and studied by adopting orthogona 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＞Bin turn,and effect on single date weight is N＞PPA＞B＞Zn＞P;differences in yield increments between N99 and N180,PPA5 and PPA10 are extremly marked among the factors;total yield of N90 is 24.5% higher than that of N180 and total yield of PPA10,9.7% higher than that of PPA5;differences in enlarging date fruit beteen N90 and N180,PPA5 and PPA10 are extremely marked,and that between B12 and B24 is marked;among them,single date weight of N180 is 8.1% higher than that of N90,PPA10’s single date weight is 6.6% higher than PPA5’s and B12’s is 4.5% higher than B24’s.Based on the analyses mentioned above,N90P45B12Zn15PPA10 is determined as the optimized recipe of special foliage fertilizer for jujube tree through integrated evaluations and cost analyses. |
