选用黑龙江省第一积温带主栽(或曾经主栽)的三个品种,代表三种不同类型的品种:分别是穗重型、中间型、穗数型,设置3种不同的栽培密度,3个不同的施肥水平,共计27个处理,通过收获后室内考种,从而确定最优产量的处理。结果表明,穗重型品种在亩施纯N14kg、密度在20穴/㎡栽培条件下表现产量最高;中间型品种在亩施纯N12kg、密度在23穴/㎡栽培条件下表现产量最高;穗数型品种在亩施纯N14kg、密度在25穴/㎡栽培条件下表现产量最高。
The three cultivars (or formerly cultivated) of the first accumulated temperate zone in Heilongjiang Province were selected to represent three different types of cultivars: panicle type, intermediate type and panicle type. Three different planting densities were set up and three Different fertilization levels, a total of 27 treatments, through the indoor test after harvest test to determine the optimal yield of treatment. The results showed that the highest yield of spike heavy varieties was N14kg at Mushu pure density and highest density under cultivation conditions of 20 holes / m 2. The middle type had the highest yield under the condition of N12kg per mu and density at 23 holes / ㎡ cultivation. Mushu varieties in the pure N14kg, the density of 25 holes / m cultivation performance under the highest yield.
