Abstract
In order to find out high-yielding cotton cultivation of agroecology in apricot-cotton intercropping which planting spacing is 3 m×6.5 m, and height is 5.45 m, the experiment is conducted with three field arrangements on cotton plant growth and tempo-spatial distribution of boll. The results showed that field arrangement with 10 cm plant spacing, 10 rows (B) has the lowest length-width ratio, and a better performance in main stem leaf number, width of the top fourth leaf and fruit branch number than others. Stem diameter was positively related to plant spacing. Cotton individual of dry matter was higher than others, dry matter of gross was positively related to individual; dry matter of net was positively related to density. Shade delayed the growth of cotton,leading to three treatments were the most of summer bolls and autumn bolls; bolls mainly distributed close to stem in horizontal, as plant spacing increased; longitudinal were main compose of middle bolls and lower bolls. Lint yield of gross plant in plant spacing of 10 cm (B) was the highest, higher 4.69% and 19.96% than plant spacing of 12 cm and 8 cm; Lint yield of net plant in plant spacing of 8 cm was the highest, higher 7.18% and 30.91% than plant spacing of 10 cm and 12 cm.
