花生不同施钙量、密度对产量影响的裂区试验

Split plot experiment of different calcium application amounts and planting density's impact on yield of peanut

探讨不同施钙量、不同播种密度对花生产量的影响,为生产上提供施用钙肥与合理播种密度的理论依据。采用两因素裂区试验,A(施钙量)因素为主处理,设有4个水平,即:A1为0石灰/hm2、A2为300kg石灰/hm2、A3为600kg石灰/hm2、A4为900kg石灰/hm2;B(播种密度)因素为副处理,设有4个水平,即:B124万粒/hm2、B228.5万粒/hm2、B331.5万粒/hm2、B436万粒/hm2;3次重复。实验结果表明:施用300石灰/hm2、播种密度28.5万粒/hm2,可获得较高产量,达到3202.83 kg/hm2和最高的净收入,达到11531.16元/hm2。

To explore different calcium application amounts and planting density＇s impact on yield of peanut, and to provide theoretical basis for rational calcium application and peanut planting density in pro- duction. Two factors split plot experiment was adopted： A factor （calcium application amount） as main treat- ment with four levels of Al 0 lime/hm^2, A2 300kg lime/hm^2, A3 600kg lime/hm^2and A4 900kg lime/hm^2; B fac- tor （planting density） as sub-treatment with four levels of B1 240 thousand grain/hm^2, B2 285 thousand grain/hm^2, B3 315 thousand grain/hm^2 and B4 360 thousand grain/hm^2;three repeats. The experimental results show that 300 kg lime/hm^2 and 285 thousand grain/hm^2 of planting density can obtain higher yield with 3202.83 kg/hm^2 and highest net-income： 11531.16 Yuan/hm^2.
