| Abstract: | The big ridge in 140cm cultivation could solve the problem of ventilation andPhotopermeability in vast corn field.Compared the ridge in 140 cm with the ridge in 70 cm,the effect of ventilation and Photopermeability was significant.The yield for the ridge of in 140 cm was 10 746 kg/hm~2,and was 9 666 kg/hm~2 for the ridge in 70 cm,the yield increased 1 080 kg/hm~2,the ratewas 11.2%,the benefit was 864 yuan/hm~2. |
