不同浓度营养液对黄瓜营养元素含量的影响研究
|
摘要
使用不同浓度营养液浇灌黄瓜植株,研究植株地上部分(茎、叶)及地下部分(根)的干质量和营养元素含量的关系。采用霍格兰营养液培养黄瓜,霍格兰营养液设为T1、T2、T3、T4、T5,每隔一段时间采样一次并及时烘干恒重后测量不同浓度根茎叶的质量及养分含量。结果表明T4浓度为最适营养液浓度,为温室黄瓜无土栽培发展提供了重要理论基础和实用价值。
Effects of different concentrations of nutrient solution on dry weight and nutrient content in aboveground(stem,leaf) and Underground parts(root) of Cucumber plants.The cucumber was cultivated by Hoagland nutrient solution.It was set as five concentration gradients of T1,T2,T3,T4 and T5.The quality and nutrient content of rhizomes and leaves of different concentrations were measured at a time of time and after constant drying.The results showed T4 concentration is the optimum concentration of nutrient solution,which provides an important theoretical basis and practical value for the development of soil less cultivation of cucumber in greenhouse.
