摘要
研究了不同抛栽密度对早熟高产杂交晚稻新品种湘优196产量的影响,结果表明:水稻产量和抛栽密度呈极显著抛物线相关(y=-259.48x2+3 004.7x-60.717,r=-0.902 9**),抛栽密度为51万株/hm2时,产量最高,达到8 827.36 kg/hm2。
Study on the effects of different seedling density on early maturing,high-yielding,late hybrid rice new varieties of Xiangyou 196 was carried ,the results showed that the yield of rice was significantly correlated with the density of throwing（y=-259.48χ^2＋3 004.7x-60.717 ,r=-0.902 9）, the yield was the highest when the density was 5.1 × 10^5 plants/hm^2, reached 8 827.36 kg/hm^2.
