通过改变栽培方向及优化种植行距能够提高籼型杂交稻的光合效率。以气象学风向类型为依据，设22.5°间距、4类8个行向处理，并配以宽窄组合行距为基础，得出本地水稻栽培优化行子为“二顺一组”，即行向午时顺光、生长期全程顺风的南偏西或近南北行向和宽窄行（50-30 cm）组合栽插，其可以提高水稻光合效率，增强抗性，从而提高产量。
通過改變栽培方嚮及優化種植行距能夠提高秈型雜交稻的光閤效率。以氣象學風嚮類型為依據，設22.5°間距、4類8箇行嚮處理，併配以寬窄組閤行距為基礎，得齣本地水稻栽培優化行子為“二順一組”，即行嚮午時順光、生長期全程順風的南偏西或近南北行嚮和寬窄行（50-30 cm）組閤栽插，其可以提高水稻光閤效率，增彊抗性，從而提高產量。

The high photosynthetic efficiency cultivation of indica hybrid rice was obtained through changing the direction of cultivation and optimizing the linewidth. Based on the wind types in meteorology ,set 22.5° interval for four main directions and eight cultivation orientations ,combined with wide and narrow lines to deal with the cultivation of indica hybrid rice. The test results indicated that the optimized condition was “two cis and one combination”,Which meant the cultivation orientation was in the same direction as the noon sun and grew in the direction of the south westerly or north-south wind during the whole growth period ,and the planting was a combination of wide and narrow lines (50-30 cm ). This technique could increase the light efficiency and therefore increased the yield and disease-resistant performance.
