摘要
为了实施基质限根栽培、提高化肥施用效果,设置了2个不同营养液配方及施肥量处理的肥料试验,分析了樱桃番茄(Lycopersicon esculentum var.cerasiforme Alef.)在椰糠基质栽培情况下氮、磷、钾的肥料利用率。结果表明,2个处理氮、磷、钾的肥料利用率分别为58%、44%、64%和59%、30%、67%;利用椰糠基质栽培后,基质pH有所下降,部分养分和盐分有累积现象。
In order to implement substrates cultivation under root system control and improve the effect of fertilizer application,two different nutrient solution treatments were set up to study the utilization rate of nitrogen,phosphorus and potassium under coconut-coir cultivation of cherry tomato(Lycopersicon esculentum var.cerasiforme Alef.).The results showed that the utilization rate of nitrogen,phosphorus and potassium of two treatments were 58%,44%,64%and 59%,30%,67%,respectively.After the cultivation,the pH of coconut-coir substrate was decreased,the partial nutrients and the salt content were accumulated.
