不同栽培模式对红小豆产量和单株性状的影响

为了明确不同耕作方式下的肥密组合对红小豆群体产量和个体性状的影响,通过设定3种耕作方式平作、大垄(110cm)、小垄(65cm)]、3种肥料梯度和5个种植密度,分析不同因素、不同栽培模式对红小豆群体产量和单株性状的影响。结果表明:110cm垄作(N)的耕作方式优于平作(P)和65cm垄作模式(S);高施肥量(240kg·hm~(-2))的增产效果不明显;中低密度处理(13万~17万株·hm~(-2))有利于提高单株生产力和群体产量;3种耕作模式下的肥密互作效应显著。3种栽培模式中,65cm垄作(S)和平作模式(P)的应用需结合实际情况而定;110cm垄作模式下,商品肥施入量80~160kg·hm~(-2)、种植密度13万株·hm~(-2)的处理组合(NF2M2和NF1M2)分别比对照(SF1M2)的产量提高28.3%和32.1%,是兼顾产量和效益的处理组合。

Effect of Different Tillage Patterns on the Yield and Single Plant Characters of Adzuki Bean

In order to explicit the effect on population yield and single plant characters of fertilizer and density combination under different tillage patterns ,three tillage patterns (flat planting ,110 cm and 65 cm ridge plant‐ing) ,three kinds of fertilizer usage applying amount ,and five density treatments were chosen to analyze the effect of different factor and tillage patterns on the population yield and single plant characters .The results showed that 110 cm ridge planting (N) was better than flat planting (P) and 65 cm ridge planting (S) among different tillage patterns .The effect of increase yield was not apparent for the high fertilizer usage (240 kg· hm‐2 ) on the population yield .The medium and low‐density treatment (13 × 104 ~17 × 104 plant·hm‐2 ) was benefit to enhance the single plant production capacity and population yield .The interaction effect of fertilizer and density was apparent during the application of three ridge planting .For the three kinds of cultivation pat‐tern ,the application for the 65 cm ridge planting(S) and the 110 cm ridge planting(N) were based on the actual condition .In the 110 cm ridge planting pattern (N) ,the treatments which fertilizer apply amount was 80~160 kg·hm‐2 and plant density was 13 × 104 plant·hm‐2 ,its yield increase percentage was 28 .3% and 32 .1% than the control (SF1M2) ,which was the optimum treatment combination for yield and profit .
