不同磷素形态对黄瓜生长和丛枝菌根真菌接种效应的影响
Effects of Applying Different Forms of Phosphoric Fertilizer on Cucumber Growth and Inoculation of AM Fungi
摘要
Abstract
The effects of KH2PO4 and Na-phytate on cucumber growth and inoculation of AM fungi by pot culture were studied. The results showed that there was no significant difference between the biomass, soluble sugar and soluble protein in the leaves of cucumber plants inoculated with and without AM fungi if phosphoric fertilizer wasn't applied,but POD activity and the content of phosphorus in the leaves where the cucumber plants were inoculated with AM fungi were significantly higher than that without inoculating AM fungi. Under the conditions of applying KH2 PO4, the growth of cucumber plants inoculated with AM fungi could be significantly promoted, and the content of phosphorus in the leaves was obviously increased,but there was no difference between the soluble sugar and soluble protein in the leaves of cucumber plants inoculated with and without AM fungi. Under the conditions of applying Na-phytate, the effects of inoculating AM fungi on the biomass of cucumber plants, the soluble sugar,the soluble protein and the content of phosphorus in the leaves weren' t so significant,but SOD activity in the leaves was significantly higher than that without inoculating AM fungi. Under the conditions of inoculating AM fungi,the concentration of available phosphorus in the rhi-zosphere of cucumber plants was in an order of KH2P04 > Na-phytate > CK. There was no significant effects of the forms of phosphorus on the inoculation efficiency of AM. When phosphoric fertilizer wasn't applied, the inoculation efficiency of AM was significantly higher than that of KH2PO4 and Na-phytate applied,which revealed that AM fungi could promote the inoculation efficiency of cucumber roots when the content of a-vailable phosphorus in soil was low.关键词
