黄瓜生长最适土壤质地的探究

Study on the Most Suitable Soil Texture of Cucumber

试验以黄瓜品种“津优30号”为材料,研究砂质黏壤土、砂质壤土、粉砂质黏土三种不同质地土壤对黄瓜生长的影响,观察黄瓜植株叶片数、株高、茎粗的变化。结果发现,经7周培育后,三组处理的株高差异显著,而叶片数及茎粗方面变化不明显。在第7周时,砂质壤土中的植株叶片数为18、株高64 cm、茎粗1.8 cm,为同一时期三组处理中长势最好的。砂质黏壤土中植株叶片数为16,株高55 cm,茎粗1.7 cm;粉砂质黏土中植株叶片数为17,株高35 cm,茎粗1.6 cm。黄瓜在不同质地土壤的整体长势为砂质壤土>砂质黏壤土>粉砂质黏土。

The experiment selected"Jinyou No.30"as test material and choosed sandy clay loam,sandy loam and silty loam to analyse its influence on growth respectively recorded cucumbers’leaf number,height and stem diameter.After 7-week cultivation,it turned out that three groups had significant differences in plant height,but had no obvious changes rules of leaf number and stem diameter.In the seventh week,the plants in sandy loam grow best among three groups during the same period and have 18 leaves with 66 cm tall and 1 cm thick stem.The plants in silty loam had 17 leaves with 35 cm tall and 1.6 cm thick stem.The plants in sandy clay loam grow have 16 leaves with 55 cm tall and 1.7 cmthick stem.The results indicated that cucumber growth condition with different soil texture was in the order of sandy loam>sandy clay loam>silty loam.
