【中文摘要】 本項(xiàng)研究表明:蘑菇、草菇、鳳尾菇以稻草為原料,在開放式栽培條件下,培養(yǎng)料中都有固氮菌存在,據(jù)我們測(cè)定,每克料含量變動(dòng)在0.4—44000萬個(gè)之間,三類菇料中固氮菌的固氮酶活性,高的可達(dá)1毫微克分子乙烯/瓶,小時(shí),低的只有7.42×10-5毫微克分子乙烯/瓶,小時(shí)。三類菇料中分離到的固氮菌與其相應(yīng)菇類的關(guān)系:一是,所有固氨菌與其相應(yīng)菇類可以共同生長(zhǎng);二是,某些固氮菌對(duì)菇類尚有促生作用;三是,有的固氮菌與相應(yīng)菇類一起生長(zhǎng),其固氮酶活性可以得到提高。上述結(jié)果告訴我們,在這些菇類栽培中應(yīng)用固氮菌為菇類創(chuàng)造有利生物因素是值得深入研究的。菇類的生長(zhǎng)發(fā)育,離不開特定的環(huán)境條件,環(huán)境條件適宜,可使菇類處于最佳的生長(zhǎng)狀態(tài),從而獲得理想的產(chǎn)量和質(zhì)量,影響菇類生長(zhǎng)發(fā)育的環(huán)境條件,有物理因素、化學(xué)因素及生物因素。生物因素中有害因素的防治,已經(jīng)引起人們的重視,創(chuàng)造和運(yùn)用有利生物因素則顯得不足。本項(xiàng)研究想通過對(duì)菇料中固氮菌的數(shù)量、固氮酶活性,固氮菌與菇類的關(guān)系等方面的調(diào)查,為改善菇類栽培中的生物因素或?yàn)楣痰诠筋愒耘嘀械膽?yīng)用,提供一些科學(xué)依據(jù)。

【英文摘要】 This investigation showed that,1.Under opening culture condition,it is always found the N-fixing microorganisms which amounted between 0.4—44000×104/g sample in the straw media of Agaricus, Volvariella and Pleurotus.2.The N-fixing activites of the microorganisms growing in three culture media are varied from 1—0.00007 nM C_2H_4/vase.hr.3.The relationships between microorganisms isolated from three media and relevant mushrooms are:a.associative growth with relevant mushroom;b.stimulating reation to the mushroom;c.N-fixing activity is greatly increaseb when growing it together with relevant mushroom. For these reasons,it is valuable to make further investigation on using the microorganisms in the media to create a convenient biological environment for the growth of mushrooms.
