Abstract: [Objective and Method]The aim of this text was mainly to study relations of together growth on organs and cotton bolls'spatial distribution of Super high-yielding cotton,[Result]the relation of together growth of fruit branches'first cotton bud and the main stem leaves is n+1.5～n-1.2;The relation of together growth of fruit branches'first flower and the main stem leaves is n+6.2～n+8.8(n for the bit of main stem leaf with the same frui-bit). [Conclusion]The proportion of the central-lower and interior part of bolls of super high-yielding conventional varieties cotton reached 90;,it is the main part of super high-yielding cotton bolls, The top part of bolls is about 10;,the top and external bolls is ultra-high yield potential; The proportion of the central bolls of super high-yielding hybrid'cotton is 50;, the proportion of the lower and top bolls is almost same, the bolls of foliage branch is 4.3;, The proportion of the external bolls is nearly 40;, the top and external bolls is the key of super high-yielding cotton.
