| 摘 要： | 以双季早、晚稻超高产品种陆两优996和淦鑫688为材料,以金优402和汕优10号为对照,研究了施磷量对其产量和稻米品质的影响。结果表明,施磷对非超高产品种的增产效应大于超高产品种,对早稻的增产作用主要是增加有效穗数,而对晚稻主要是增加每穗粒数。施磷增加早稻垩白米率和垩白度,但降低晚稻的垩白米率和垩白度,施磷显著增加稻壳和糙米中的植酸含量。等量施磷时,移栽前施磷处理的稻壳中植酸含量高于播种前施磷处理,而稻米中的植酸含量则相反;幼穗分化期施磷降低稻壳中的植酸含量,而增加糙米中的植酸含量。

| Abstract: | Effects of P amount on yield and quality were studied with super high-yielding early rice variety Luliangyou 996 and late rice variety Ganxin 688,and normal hybrid rice varieties(control variety) Jinyou 402 and Shanyou 10.The effect of P-applied on increasing yield of non-super higher-yielding varieties was higher than that in super higher-yielding varieties.Yield increased by P-applied in early rice was mainly through raising effective panicles,but more spikelets were found in late rice under P-applied.Rat... |
