Mycorrhizal research on nitrogen - fixing plants
固氮菌的溶磷性和分泌植物生長素特性測定
Fixed plant assets management systems
設備固定資產(chǎn)管理制度
Finally , where markets were more extensive , where there was a substantial investment in fixed plant , and where workers were subjected to formal discipline , some firms in the traditional mill industries other than the textile and iron industries achieved factory status
最終，在市場更廣闊，對固定廠房設備投資巨大，工人受到規(guī)范化組織管理的地方，除了紡織與制鐵行業(yè)外，其他一些傳統(tǒng)的制造行業(yè)也達到了工廠化狀態(tài)。
Advances in mycorrhizal research on nitrogen - fixing plants were introduced . the universality of mycorrhizal formation in nitrogen fixing plants , the reciprocal promotion effect of symbiosis , and the application prospect of mycorrhizal techniques under stressed conditions were summarized and reviewed . the mechanism of enhancing nitrogen fixation of n - fixing plants by mycorrhizal fungi in symbiosis was preliminary discussed
綜述了固氮植物菌根研究的概況，并對固氮植物形成菌根的普遍性、固氮植物聯(lián)合共生的增效作用及逆境條件下菌根技術在固氮植物上的應用前景進行了總結和評述，初步探討了聯(lián)合共生體中菌根菌促進固氮植物結瘤固氮的機理
