１９９７～１９９８ 年，在长沙县基点利用多品种进行了优质稻硫镁钙的吸收运转规律研究。试验结果表明，每公顷生产 ６２～８０ ｔ 优质稻谷，需吸收 Ｓ １４１～１８９ ｋｇ， Ｍ ｇ １８．０～２８．１ ｋｇ， Ｃａ２４．３～３５．４ ｋｇ；生产１００ ｋｇ 稻谷的 Ｓ， Ｍｇ， Ｃａ 吸收量优质晚稻高于普通晚稻，更高于优质早稻。稻株最高含 Ｓ量在分蘖期，成熟期最低； Ｍ ｇ， Ｃａ 则与 Ｓ相反。吸 Ｓ高峰２ 个，主峰在孕穗至齐穗（０３０～０３１ ｋｇ／ｈｍ ２·ｄ）； Ｍ ｇ， Ｃａ 吸收高峰分别在孕穗前后（０５９～０６３ ｋｇ／ｈｍ ２·ｄ）和穗分化至孕穗间（０７４～０９３ ｋｇ／ｈｍ ２·ｄ）。向谷粒中的运转率为 Ｓ＞ Ｍｇ＞ Ｃａ，优质稻低于普通稻；表观运转率优质稻亦低于普通稻。 From 1997 to 1998, we studied the absorption and transportation of sulfur, magnesium and calcium in high-quality rice by using many varieties in the base of Changsha County. The results showed that the yield of high quality rice of 62 ~ 80 t per hectare needed to absorb S 141 ~ 189 kg, M g 18.0 ~ 28.1 kg, and Ca 24.3 ~ 35.4 kg. The yield of S, Mg and Ca of 100 kg rice was higher than that of normal late rice and higher quality early rice. The highest S content in rice plants was the lowest at tillering stage and the maturity stage; M g, Ca was opposite to S. The peak of S absorption peaked from booting to full spike (030 ~ 031 kg / hm 2 · d), and the peak of M g and Ca uptake was around booting (059 ~ 063 kg / hm 2 · D) and panicle differentiation to booting (074 ~ 093 kg / hm 2 · d). The running rate of grain to grain was S> Mg> Ca, while that of good quality rice was lower than that of normal rice. The apparent running rate of high quality rice was also lower than that of common rice.
