题目：新疆杂交棉育苗移栽稀植群体冠层结构特征及与产量关系的研究 摘要：在北疆气候生态条件下，以杂交棉品种新陆早43号和鲁棉研24号为材料，采用育苗移栽进行稀植，研究移栽稀植条件下冠层结构形成、光合特性及产量的变化。结果表明：当移栽密度在1.5-4.5万株∙hm-2低密度条件下，单株结铃数增加，单铃重提高，但由于单位面积植株少，总铃数有所下降，与采用常规的矮密早模式下的对照产量低；稀植条件下3万株/hm2与4.5万株/hm2产量相近，但用苗量少50%，皮棉产量可达到2900 kg∙hm-2高产水平；同时生育进程有所提前，霜前花率提高20%，因此，以实现稳产为目标，在播种出苗期灾害较多的北疆地区可以采用移栽稀植。 |

The study of the relationship between the canopy structure and the production of transplanting Xinjiang hybrid cotton Abstract: The hybrid cotton varieties of Xinluzao 43 and Lumian 24 were studied in the northern climatic conditions. The canopy structure, photosynthetic characteristics and yield were studied with the transplanting cotton at low density via thin planting seedling transplanting. The results showed that: the number of bolls and its weight were increased when transplanting density was at 1.5-4.5 million/hm-2. But the total boll number was decreased for the fewer plants at per unit area and the production was lower compare to the conventional way. The production were similar at the density of 30,000 / hm2 and 45 000 / hm2 while the seedlings could save 50% for 30,000/hm2. Moreover, the production of lint could up to 2900 kg/hm-2. At the same time, the process of growth was become faster and the flowers before frost increased by 20%. Therefore, the sparse transplanting could be used in northern regions where has more disaster in order to achieve stable production. |
