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. |
