怀卵量 meaning in Chinese
brood amount
Examples
- The nontoxic m . aeruginosa , however , had no negative effects on the growth of the water fleas
无毒微囊藻虽然不影响虫体的生存，但影响其怀卵量和幼体产出。 - 2 ) while at suitable temperatures , 60 - 80 % relative humidity is suited for cultivating the cochineal insect , and comparing from the size and eggs of the female adults , high relative humidity is more suited for the cultivation of the insect
2 )在合适的温度条件下， 60 % rh到80 % rh对胭脂虫的培育是适宜的，从雌虫体大小和怀卵量上比较，高湿度更有利于胭脂虫的培育。 - The reasons of small resource are 1st , the fish eggs is lack of sticky and most spawning ground is not comfortable for spawning ; 2nd , the fish matures about 5 years old and fecundity is in low level on absolute or relative eggs amount ; 3rd , the shape is easier for catching with tall width and thin body
黑龙江鲂资源量少的原因为：黑龙江鲂为产弱黏性卵的鱼类，对产卵场的要求较高。黑龙江鲂的性成熟年龄较大( 5龄) ，而且无论是绝对怀卵量还是相对怀卵量都较低，因此生殖力较低。黑龙江鲂由于体形高而侧扁，极易被捕捞。 - Through cultivating the cochineal in 4 counties which belonging to tropical , south sub - tropical and mid sub - tropical zones , the life tables of the cochineal in each county are established and the survival percentage of each stage as well as the key factor of death in each climate type is studied . in the meantime , the sample of the cochineal of each county is collected to test the size , eggs and weight , through comparing these biological index , the best zones , better zones and other zones for cultivation of the cochineal are pointed out . on the basis of above study , the zones for cultivating the cochineal are marked out in yunnan province
在云南热带、南亚热带、中亚热带三个气候类型下的4个县(市)放养胭脂虫，应用生命表技术，研究各气候类型下胭脂虫的存活情况并分析出各气候类型下胭脂虫的主要致死因子，同时，采集各地培育的胭脂虫样品测定虫体大小、怀卵量及重量，通过比较这些生物学指标，得出胭脂虫的最适生区、次适生区及适生区，并以此为依据，对云南省胭脂虫的培育进行了区划。 - On the basis of foreign documents , the dissertation firstly describes the morphology , taxonomy , and biological characters of cochineal insects . then , by using artificial climate cases in the lab , according to orthogonal design , 8 lands of combinations of temperature , humidity and light is set , while the temperature has four levels : 15 , 20 , 25 and 30 , and the relative humidity has two levels : 60 % and 80 % , while the light also has two levels : 980 lux and 60 lux . through observations and analysis of hatching percentage , survival percentage of the first instar and during from the second instar to the adult , the population tendency index , generation life cycle , size and eggs of female adult , the development of the cochineal under different conditions is studied
在收集、整理国外对胭脂虫的研究资料基础上，首先从胭脂虫的形态学、分类学、生物学特性入手，进而在实验室内利用人工气候箱，应用正交设计方法，设计了4种温度、 2种湿度、 2种光照梯度的不同组合，通过测定胭脂虫的孵化率、 1龄若虫的存活率、 2龄若虫至成虫期存活率、种群趋势指数、世代历期、雌成虫的大小、怀卵量等生物学指标，深入研究胭脂虫在这些组合下的生长发育状况，应用数理统计方法，分析出温度、湿度和光照对各项生物学指标的影响，找出胭脂虫适宜的室内培育条件，并为野外胭脂虫的培育提供一定的理论依据。
