| Abstract: | In this paper,we use Shendan 16 as the indicator species,study on the corn balance fertilization in ditch sowing in double-ridge mulched with plastic film in Longdong in Gansu province.The results showed that corn equivalent yield was 13 806 kg/hm^2 when the amount of N were 200 kg/hm^2,P were 200 kg / hm^2,K were 125 kg/hm^2（N200P200K125）,corn yield increased by 13.28% and 1.00% compared with CK and OPT,respectively.The output value of 26 232 yuan / hm^2,increased by 3 077 yuan / hm^2 and 259 yuan / hm^2 compared with CK and OPT,respectively,while the net income was the highest,up to 23 692 yuan / hm^2,increased by 537 yuan / hm^2 and 1 129 yuan/ hm^2 compared with CK and OPT,respectively,it can be used as a better balanced fertilization technology in Longdong arid area. |
