花生不同施钙量、密度对产量影响的裂区试验

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。

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

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.
