17、 cultivation, beneficial to the improvement of the biological conversion rate. 小结与讨论Summary and discussion 鸡腿菇是一种腐生真菌,生长所需的营养物质完全由培养料提供,通过鸡腿菇在各培养料中的生长特性和菇体的生物学效率可以看出,4个配方之间有很大的差异,说明鸡腿菇菌株对各配方培养料的适应能力不同,因而在生产上的应用价值也不同。从试验结果看,菌丝长速快,现蕾时间短的生物学效率相对较高,此种现象与菌丝中养分的积累有关,菌丝长速快,有利于养分的积累,这为以后的出菇,提高产量和品质奠定了良好的营养基

18、础。在菌丝生长阶段,菌丝在维持自身呼吸作用的同时,要积累一定的养分,因此表现为培养基失重,即菌丝降解培养料中的复杂有机成分可供菌丝直接吸收的简单物质,同时释放CO2和H2O,因此,基物失重也可以作为评价菌株降解能力的一个指标,在评价培养料为鸡腿菇提供的营养源和能源时,要综合考虑菌丝长速,基物失重,现蕾时间以与产量和生物学效率等因素。棉籽壳、木屑、玉米芯三料合理混合培养鸡腿菇是可行的,而且有显着的增产效应,表现为菌丝生长快,产量高。三料混合增产的原因是多方面的,首先3料混合可以减少培养料之间的缝隙,菌丝易于定植,可加快菌丝生长速度,使菌丝生长浓密粗壮;另外三料混合时C/N较高,具有丰富的养分,容

19、易提供鸡腿菇生长发育所需的环境条件,而单独使用一种主料尤其是以木屑、玉米芯作为主料的配方营养贫乏,C/N失衡,难以提供鸡腿菇生长所需的环境特点,培养鸡腿菇的效果相对最差。鸡腿菇是一种腐生、草生菌,具有较强的分解,纤维素的能力,据分析,玉米秸秆和果树枝条主要成分为纤维素,半纤维素,木质素。我国陇东地区每年产生大量的玉米秸秆和果树枝条,绝大部分被焚烧,不但造成资源浪费,而且严重污染环境,将其与棉籽壳混合作为鸡腿菇栽培料,不但解决了目前棉籽壳等食用菌栽培料的原料紧缺问题,而且有极大的生态效益和社会效益。但是在具体栽培过程中,要充分考虑玉米秸秆和果树枝条营养成分不能被菌丝直接吸收并且较难降解的特点,必

20、须与其它料混合使用,这样鸡腿菇菌丝才能生长旺盛,为以后的出菇奠定良好的基础。结合菌丝生长特性和菇体生物学效率,本试验所选用的4个配方中,配方4对鸡腿菇的生长发育有很大的影响,表现为菌丝长速快,菌丝浓密粗壮,产量高。因此,棉籽壳、木屑,玉米芯混合栽培鸡腿菇是较为理想。Chicken leg mushroom is a kind of saprophytic fungi, PeiYangLiao provide nutrients needed for growth, through the chicken leg mushroom in the PeiYangLiao growth charac

21、teristics and biological efficiency of mushroom body, you can see that four formula there is a big difference between, show the chicken leg mushroom strains of each formula PeiYangLiao adaptive capacity is different, and therefore have different application value in the production. From the test res

22、ults, hyphae grow faster, budding time short biological efficiency is relatively high, this kind of phenomenon is associated with the accumulation of hyphae in the nutrient, hyphae grow faster, is conducive to the accumulation of nutrients, this is the mushroom in the future, improve the yield and q

23、uality laid a basis for good nutrition. In mycelial growth stage, hyphae in maintaining their respiration at the same time, to accumulate certain nutrients, weightlessness is medium, namely the hyphae degradation PeiYangLiao complex organic compounds for hypha of direct absorption of simple substanc

24、e, and release of CO2 and H2O, therefore, the base material of weightlessness can also be used as a index of evaluating strain degradation ability, in evaluating PeiYangLiao nutrition and energy for the chicken leg mushroom, to comprehensive consideration of hypha growth rate, base content weightles

25、sness, budding time and yield and biological efficiency and other factors. The cotton seed shell, wood shavings, corn cob three reasonable material mixed culture chicken leg mushroom is feasible, and has a significant effect to increase production, performance for hypha growth is fast, high output.

26、Three mixed material output reason is various, the first 3 material mixture can reduce the gap between the PeiYangLiao, hyphae are easy to colonize, can accelerate the mycelium growth rate and make the hyphae grow thick stout; Three other mixing high C/N, has rich nutrients, easy to provide a chicke

27、n leg mushroom environmental conditions needed for the growth and development, and the single use of a cooked especially with sawdust and corn cob as main ingredient in the formula, poor nutrition, C/N balance, provides the chicken leg mushroom growth required environmental characteristics, cultivat

28、e the chicken leg mushroom effect is relatively the worst. Chicken leg mushroom is a kind of saprophytic, CaoShengJun, strong decomposition, the ability of cellulose, according to the analysis of corn stalk and fruit tree branches are based on cellulose, hemicellulose, and lignin. Longdong region ev

29、ery year in our country has a lot of corn stalk and fruit branches, for the most part are burned, and not only causes waste of resources and serious environmental pollution, the cotton seed shellis with mixed as the chicken leg mushroom cultivation, not only solved the cotton seed shellis currently

30、of the edible fungus cultivation, such as the raw material shortage problem, and have great ecological benefit and social benefit. But in the process of specific cultivation, must fully consider the corn stalks and fruit tree branches hyphae of nutrients can not be directly absorbed and refractory c

31、haracteristics, must be used mixed with other materials, in this way can a chicken leg mushroom hypha growth strong, for after a mushroom to lay the good foundation. Combination of hypha growth characteristics and mushroom body biological efficiency, the four selected for testing the formula, the formula 4 of the chicken leg mushroom growth has a big impact, show the hyphae grow faster, hyphae thick thick, high output. The cotton seed shellis so, sawdust, corn cob mixed planting chicken leg mushroom is ideal.7 / 7
