摘要
采用四因素三水平正交试验研究了秧龄、播量、密度和氮肥运筹对杂交中稻"新两优6号"产量的影响。结果表明:秧龄、播量、密度和氮肥运筹对水稻产量均有一定程度的影响,对产量影响程度依次为栽插密度(B)>秧龄(D)>氮肥运筹(A)>播种量(C)。本试验四因子的最优组合为A2B1C3D2,产量为15208.50kg/hm2。
The orthogonal experiment design of four factors and three levels was adopted to study the effects of seedling age, sowing density, seeding amount and nitroge management on the yield of Xinliangyou 6. The results indicated that the seedling age, sowing density, seeding amount and nitroge management had effects on the yield of hybrid rice. Sowing density had the greatest influence, followed in order by seedling age, nitroge management and seeding amount. The optimum combination was A2B1C3D2 ,with the yield of 1508.50kg/hm^2.
