摘要
试验以过磷酸钙为磷肥肥源,以番茄为研究对象,在施磷量相同条件下,研究磷肥作基肥与追肥不同比例对番茄的影响。结果表明,磷肥60%作基肥,40%作追肥时,番茄产量提高了15.71%,根系中氮、磷、钾含量也较高。
The calcium superphosphate was regarded as the source of phosphate fertilizer in the tests, and tomato was the research object. In the condition of the same amount of phosphate fertilizer applied to tomato growth, effect of proportion of phosphate fertilizer as basal manure and top dressing on tomato was studied in the experiment. Results were follows. When proportion of phosphate fertilizer as basal manure and top dressing was 6∶ 4, the yield of tomato were significantly increased by 15.71% and the content of nitrogen, phosphorus, potassium in root increased.
