- 摘要:
- 研究了不同N 、P 、K 及密度配合, 以及化控措施对赣豆4 号产量和经济性状的影响。结果表明:处理6(A2B3C1D2)、8(A3B2C1D3)、4(A2B1C2D3)产量最高, 分别为2835 .84kg/hm2 、2818 .08 kg/hm2和2816 .28kg/hm2 。密度和K 肥对产量影响达极显著水平,N 肥影响达显著水平, 而P 对产量的作用不大。K 能促进产量构成因子的形成, 提高单株生产力。随着密度增大、N 肥用量的增加, 株高增加, 分枝减少, 单株荚数、粒数、单株生产力降低, 百粒重减轻。P 对促进分枝、提高单株荚数有一定的作用。多效唑、叶面喷肥、钼酸铵拌种、根瘤菌拌种分别比常规种植增产14 .39 %-5 .16 %。高产试验平均产量达2673 .6 - 2814 .3kg/hm2 , 最高产量达3429kg//hm2 , 高产示范平均产量2496 .5kg/hm2 。
- Abstract:
- Studied the effect of the different N , P , K and density match , and the chemical regulator measure on yieldand economic character were utilized to investigate high yield cultivation of Ganado No .4 on the paddy field .The resultshowed that the highest yield in this experiment is treatment No .6(A2B3C1D2)、8(A3B2C1D3)、4(A2B1C2D3)for 2835 .84kg/hm2 、2818 .08 kg/hm2 、2816 .28kg/hm2respectively .Density and K to yield was very significant , and N was significant, but P was not significant .Pods per plant , seeds per plant , weight per plant , 100 -seeds weight decreased asdensity and N increased and K decreased .Height of plant increased as density and N increased .Branches decreased asdensity and N increased .P have played some actions on promoting branches and increasing pods per plant .The yieldtreated with uniconazole and praying leaves with fertilizer and ammonium molybdate and nodule increased by 14 .39 %-5 .16 % compared with CK .The average yield were reached by 2673 .6kg/hm2 - 2814 .3kg/hm2 in high -yield experiment, the maximum yield was 3429kg//hm2 , by 2496 .5kg/hm2 in high -yield demonstration.
