- 摘要:
- 为筛选出最适合黄瓜生长发育的基质配比和氮的浓度，以黄瓜（Cucumber）为试验材料，采用盆栽试验，用陶粒、珍珠岩、沙子作为基质材料，配置5种不同配比的混合基质（各3盆），研究其对黄瓜生长过程中的各项形态指标及生理指标（株高、开花情况、根系体积和叶绿素等）的影响。结果表明：在基质方面，陶粒∶珍珠岩沙子为2∶1∶1和3∶1∶1的混合基质物理性质对株高、叶片长度、根系体积、开花情况的影响都较适合于黄瓜生长。营养液方面，随着氮素的升高，黄瓜植株的株高、干重、叶绿素含量也在增加，有利于黄瓜有机物的积累。为以后黄瓜的无土栽培提供理论依据。
- Abstract:
- In order to screenign for suitable mixture ratio of base materials and nitrogen density for the growth of cucumber，taking the cucumber as materials,using potting experiment method and taking advantage of ceramsite,perlite and sand as base materials so as to configurate five mixtures of different ratios,each of which is prepared 3 pots,the morphological and physiological indexes （like plant height,blooming,root volume,chlorophyll and so on） in the cucumber growing process were sdutied.The result showed that on base materials,when the ratio of ceramsite,perlite and sand were 2∶1∶1 and 3∶1∶1,the physical property of these mixed materials suit to grow cucumber through its influence on the plant height,the length of leaf and the situation of blooming;while on nitrogen culture solution,plant height,trunk weight and chlorophyll content of cucumber turned to be positive growth with the increase of nitrogen,which would benefit the accumulation of organics in cucumber.It may provide the theory base for future soilless cultivation of cucumber.
