研究结果表明,不同砧穗组合椪柑的氮素营养存在差异。半矮化枳砧椪柑,无论是枳砧根系或是枳砧椪柑叶片,在年周期中(或一定阶段),其全氮、硝态氮含量和硝酸还原酶活性多处于较高水平,且呈现出高于两种乔砧(椪柑、福桔)椪柑组合。试验表明,枳砧根系的较高氮素水平,促进了接穗椪柑叶片氮素水平的提高,作者认为,半矮化枳砧椪柑植株氮素营养的较高水平与碳索同化水平相一致,是其早结高产的一个重要因素。
The results showed that there was a difference in nitrogen nutrition among different rootstock combinations. Semi-dwarf Poncirus angelica orange, both the root system of Poncirus trifoliata or leaves of Poncirus trifoliata, its total nitrogen, nitrate nitrogen content and nitrate reductase activity are all at a high level in the annual cycle (or at a certain stage) Out of two kinds of Joe anvil (Citrus, Fucai) Citrus combination. The results showed that the higher nitrogen level in the roots of Turandothenium anvilum promoted the increase of nitrogen level in the leaves of P. scotsmanii. According to the author, the higher level of nitrogen nutrition in the plants of Triticum aestivum leaves was consistent with the level of carbon acclimation, Its early knot yield is an important factor.
