本课题较全面地将栽培技术和优良品种有机地结合起来进行综合研究, 其结果如下:1.大豆波浪冠层栽培具有增产效果,其增产幅度6～17%;2.大豆波浪冠层群体结构改善大豆群体光量分布,扩大截光面积。在群体封垅时,植株2/3处和底部光照强度明显高于对照,该群体结构提高了群体光合速率。在 R_4期以后,增加主要源—叶片的数量和延长维持叶片活性的时间,提高了光合产物向子粒运输的能力,促进了库数量和容量的增加,促使“源库平衡”;3.研究和评价了四种波浪冠层技术,指出理想途径是采用仅有株高相差具有丰产潜力、秆强的等位基因系的品种配制组合;4.建立了黑农33和黑农36四行、二行间种实现波浪冠层栽培的较佳途径;5.阐述了采用黑农33和黑农36较佳组合来实现波浪冠层群体结构,具有较好的推广应用前景。
This project comprehensively combines cultivation techniques and fine varieties organically to conduct a comprehensive study. The results are as follows: 1. Soybean canopy canopy cultivation has the effect of increasing yield, and its yield increase rate is 6-17%. 2. Soybean canopy population structure Improve the soybean population light distribution, to expand the cut-off area. When the population was sealed, the light intensity at 2/3 and the bottom of the plant was significantly higher than that of the control, and the population structure increased the population photosynthetic rate. After R_4, the increase of the number of main source-leaves and the prolongation of the maintenance of leaf activity increased the ability of photosynthetic products to transport to the pellets, promoted the increase of the number and capacity of the pools, and promoted the “balance of source and sink”; 3. The research and Four kinds of wave canopy technology were evaluated, and the ideal way was to use a combination of varieties with only high allelopathy lines with high yield potential and stalks.4. The best ways to realize the canopy cultivation between rows are given.5. Describe the better combination of applying the combination of Heinong33 and Heinong36 to achieve the canopy structure of the canopy, which has a good prospect of popularization and application.
