两系杂交稻的产量潜力为世人瞩目。在当前早季中熟高产三系组合较缺乏的情况下,探索两系早杂高产栽培技术尤为必要。1990年我所引进籼型两系早杂组合W6154s/测49(省农科院水稻所)和三系早杂新组合汕优102(萍乡市农科所)、江优1126(省农科院水稻所)进行高产栽培技术研究;并在抽穗前喷施叶面宝及进行肥料种类等辅助性试验,三组合试验面积分别为1.08亩、1.78亩、1.59亩。试种结果以W6154s/测49产量最高,单产达516.3公斤。三个组合在完全相同条件下定点,定单株进行分蘖。主茎叶龄发育追踪观察及室内
Two-line hybrid rice yield potential for the world attention. In the current early maturing high yield three-line combination of the lack of circumstances, to explore the two lines of early hybrid high-yielding cultivation techniques are particularly necessary. In 1990, we introduced indica two-line early hybrid combinations W6154s / measure 49 (Provincial Academy of Agricultural Sciences rice) and three lines of early hybrid new combinations Shanyou 102 (Pingxiang City Agricultural Institute), Jiang You 1126 (Provincial Academy of Agricultural Sciences Rice) to carry out high-yielding cultivation techniques; spraying foliar fertilizer and other auxiliary tests before heading, the three experimental areas were 1.08 acres, 1.78 acres, 1.59 acres. Test results to W6154s / measured 49 the highest yield of 516.3 kg. The three combinations were spotted under exactly the same conditions and the tillers were planted.
