硼肥与菜籽同播对油菜出苗、产量及硼肥表观利用率的影响
Effects of simultaneous sowing of boron fertilizer and rapeseeds on seedling emergence, yield and boron utilization efficiency
摘要
Abstract
To simplify the rapeseed cultivation,simultaneous operation of seed sowing and boron fertilizer application was studied in field using 2 cultivars (Huayouza 9 and Huayouza 62) of Brassica napus L.Results showed that simultaneous sowing of rapeseeds and boron fertilizer had no negative effect on seed emergence under the normal boron application.The emergence rate were all over 80％ with both H9 (Huayouza 9)and H62 (Huayouza 62).Compared with control,simultaneous operation increased 3.3-13.3 (H9) and 1.7-15.3 (H62) percentage points on the emergence rate respectively.The proper amount of boron was between 4.5 to 9.0kg · hm-2.Moreover,simultaneous operation promoted seedling growth.Boron 13.5kg · hm-2 led to the highest yield.By equation fitting,the optimum boron amounts were 13.4kg · hm-2 and 10.lkg · hm-2 to H9 and H62 respectively.Boron utilization efficiency was also improved.Under 13.5kg · hm-2 boron fertilizer,H9 had higher use efficiency (26.5％) than that of H62 (23.1％).These results indicated that the simultaneous method could be used in rapeseed production.Under boronstarvation (≤0.25mg · kg-1) area,the recommendation boron fertilization rate was 10-13.5kg · hm-2.关键词
