摘要
聚丰套餐肥对油菜生长发育及产量的影响试验采用大区对比方法,结果表明:施用聚丰套餐肥比常规施肥和配方施肥,油菜在苗期至蕾薹期和成熟期营养条件较充分,能明显促进根系发育,植株健壮,生长势较强,抗性较好,有效分枝、角粒数较多,产量及经济效益较高。聚丰套餐处理区,油菜平均产量3 174.0 kg/hm2,除去成本后,平均产值16 058.4元/hm2,比常规施肥处理区、配方施肥处理区分别增产768.0、418.5 kg/hm2,增产率31.9%、15.2%,增加经济效益3 295.8、2 253.6元/hm2。
The test of influence of the poly feng packages fertilizer on growth and yield of rape showed that the application of poly feng packages could obviously promote the growth of root system ,robust plants, stronger growth potential, better resistance, effective branches, more effective branch numbers and grain number, grain yield and higher economic benefit than the treatment of the conventional fertilization and formula fertilizer when the rape was in seedling stage to budding stage and mature stage with full nutritional conditions ,the average yield of rapeseed was 3 174.0 kg/hm2,removal costs,the average value was 16 058.4 yuan/hm2,the yield respectively increased 768.0 kg/hm2 and 418.5 kg/hm2 than the treatment of conventional fertilization and formula fertilizer area, increasing rate were respectively 31.9%, 15.2%, economic benefit increased 3 295.8 yuan/hmz and 2 253.6 yuan/hm2 respectively.
