    摘要:

    在不同供鐵水平氣霧栽培實(shí)驗(yàn)條件下，測(cè)試了微型種薯相關(guān)生理指標(biāo)，分析了營(yíng)養(yǎng)液中不同鐵離子濃度對(duì)微型種薯的相關(guān)生理指標(biāo)的影響，以期探求合理供鐵量以提高微型種薯的品質(zhì)和產(chǎn)量。結(jié)果表明：鐵素缺乏與過量都會(huì)抑制葉綠素a和b的合成，一定程度上減少蛋白質(zhì)含量，抑制光合作用，使光合產(chǎn)物的積累減少，供鐵不當(dāng)會(huì)降低微型種薯的品質(zhì)和產(chǎn)量，提出了在溫室環(huán)境下氣霧培法生產(chǎn)馬鈴薯微型種薯的營(yíng)養(yǎng)液中適宜鐵離子濃度。

    Abstract:

    Under the aeroponics cultivation experiment of the different levels of Fe, the relative physiological indexes of the potato minituber was tested. The effect of the different concentrations of Fe ion on relative physiological indexes of the potato minituber was analyzed to explore reasonable application of Fe for improving the quality and yield of potato minituber. The results showed that iron content would affect the synthesization of chlorophyll a and b. Protein contents decreased in a certain extent. Photosynthesis and the accumulation of photosynthetic products decreased. The experiment validated that the unsuitable application of Fe reduced the quality and yield of potato minituber. The suitable Fe ion concentration of nutrient solution in cultivation of the potato minituber with aeroponics method in greenhouse was put forward. 
