The Effects of Application Amount of Nitrogen on Yield and Yield Components of Hybrid Rice Combination--Shanyou 136
Zhou Changhai (Lixiahe Region Agricultural Institute of Jiangsu,Yangzhou 2250007)
The effects of the different application amounts of Nitrogen on yield and yield components of hybrid rice combination--Shanyou 136 were analyzed.The results suggested that the key cultural techniques of getting high yield were to raise suitable effective panicles, and sufficient total spikelets, to improve the seed-setting and grain weight. The effective panicles with approximate 2.4×10 6/hm 2 and the spikelets with 4.5×10 8/hm 2 were essential for the maximum yield of Shanyou 136.
