桂平市早稻不同插植密度对比试验

Comparison Experiments on Different Rice Planting Densities in Guiping

以杂交水稻Y两优143号为材料,使用30 cm×12 cm、30 cm×14 cm、30 cm×16 cm、25 cm×12 cm、25 cm×14 cm、25 cm×16 cm进行插植密度对比,设6个处理,3次重复,随机排列。结果表明:单产最高的是30 cm×14 cm处理,平均8 460.0 kg/hm2;纯收入也是30 cm×14 cm处理最高,为3 979.5元/hm2。

Taking the hybrid rice Y double priority 143 as tested material, contrast in 6 level specifications of the planting density such as 30 cm×12 cm, 30 cm×14 cm, 30 cm×16 cm, 25 cm×12 cm, 25 cm×14 cm, 25 cm×16 cm, with 6 treatments, 3 replicates, random arrangement. The results show that the highest yield was 30 cm×14 cm treatment, average 8 460 kg/hm^2; the highest of net income is 30 cm× 14 cm treatment which was 3 979.5 yuan / hm^2.
