摘 要: | 在现有的栽培水平下,同一水稻品种要获得最大产量,必须合理控制种植密度,过稀或过密都不可能获得高产。试验结果表明:在沙洋县一季中稻区,抛栽基本苗应控制在21万~22.5万蔸/hm2(75万~81万株/hm2),即需抛栽秧盘(426孔)525~540个/hm2的秧苗,再配合合理的水肥管理,水稻单产突破10 500 kg/hm2的目标是较易实现的。

Abstract: | In the current cultivation level, the same rice varieties in order to obtain maximum yield, must be reasonable control of planting density, too thin or too dense not get the high-yielding, after testing, in the county season in the rice area per hectare Scattering basic seedling should be controlled within 210 000 - 225 000 Dou (750 000 - 810 000 Zhu), it will take Scattering 525 - 540 seedlings plate (426 holes) of the seedlings, together with reasonable water and fertilizer management of rice per hectare yield goal of breaking 10 500 kg is easier to achieve. |
