| Abstract: | Two-line japonica hybrid rice,70 you shuang 9,was studied in planting density and the amount of fer-tilizer applied. The appropriate cultivation measures of the combination were as follow: 45 hills/ha,1 to 2 seedingstem/hill;base fertilizer: 75kg/ha potash muriate and 150kg/ha urea;There were three top application fertilizers:the first time was 112. 5kg/ha urea in return green stage,the second was 75kg/ha urea in tillering stage and thethird was 75kg/ha urea in heading stage. The high yield over 8. 25t/ha of the combination could be obtained bythese cultivation measures. |
