In 2004, the experiment and demonstration on super-high density cultivation of cotton were conducted on Regimental Farm 136, Agricultural Division 8, Xinjiang Production and Construction Crops. There is only soil fertility of middle level for the experimental soil on Regimental Farm 136. The base fertilizer used for the experiment is 300 kg·hm~(-2). The topapplication by means of drip irrigation reaches 435-645 kg·hm~(-2). 12 times for drip irrigation was used in full-breeding period. The total amount of irrigation water is 4 125-4 275 m~3·hm~(-2).The chemical control was carried out for 6-7 times. Finally, the experimental result indicates that the per unit yield of ginned cotton reaches 2 419-2 571 kg·hm~(-2).
