| Abstract: | The effects of the different application amounts of Ni trogen on yield a nd yield components of hybrid rice combination--Shanyou 136 were analyzed.The r esults suggested that the key cultural techniques of getting high yield were to raise suitable effective panicles, and sufficient total spikelets, to improve t he seed-setting and grain weight. The effective panicles with approximate 2.4×1 06/hm2 and the spikelets with 4.5×108/hm2 were essential for the maximum yield of Shanyou 136. |
