| 摘 要： | 采用随机抽样和典型抽样相结合的方法,对武穴市早稻进行测产调查,分析了早稻生产特点及产量表现差异原因.结果表明,全市早稻生产轻简化栽培技术应用比例高,早稻平均产量7 254.0 kg/hm2,产量水平接近正态分布.早稻产量差异主要表现在镇(处)间、品种间及种植方式间,影响产量差异的主要原因是有效穗数和每穗粒数.

| Abstract: | Random sampling and typical sampling methods were used to estimate the production of early rice in Wuxue city and analyze the production characteristics and reasons causing yield performance variance.The results showed that light-simple cultivating technology was widely applied on early rice production in the whole city.The average yield was 7 254.0 kg/hm2 with the yield level approximate to normal distribution.The yield of early rice mainly differed among towns(departments),breeds and planting modes while the main influencing factors were effective spikelet number and grain number. |
