临夏川塬灌区饲用甜菜种植密度研究

在临夏川塬灌区饲用甜菜以种植密度4000株/667 m^2最好,块根产量达9438.3kg/667 m^2,较种植密度5800株/667 m^2处理增产2.6%,较种植密度2500株/667 m^2处理增产7.3%,块根产值943.8元/667 m^2,叶丛高度60.4 cm,平均单根重2.8 kg,其块根大小适中,群体分布结构合理,块根均匀,光滑,商品性好,效益显著,在临夏州地区大面积种植饲用甜菜时,应选择该种植密度进行种植。

Research on Planting Density of Fodder Beet of Plain-Highland Irrigation Area in Linxia

In Linxia plain-highland irrigation area,it is most suitable for planted fodder beet at a density of 4,000 plants per 667 m^2,the root yield reaches 9,438.3 kg/667 m^2,at an increase of 2.6%over the planting density of 5,800 plants per 667 m^2,and at an increase of 7.3%over the planting density of 2,500 plants per 667 m^2.,the root output value of 943.8 yuan/667 m^2,the height of leaf cluster 60.4 cm,the average single root weight is 2.8 kg,and it has a moderate root size,reasonable group distribution in structure,uniform and smooth roots,good commercial properties,and significant benefits.When planting large-scale fodder beet in Linxia,the density should be selected favorably in planting practice.
