中文拼音 [huáiluǎnliáng]
懷卵量
英文
brood amount-
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 ）在合適的溫度條件下， 60 % rh到80 % rh對胭脂蟲的培育是適宜的，從雌蟲體大小和懷卵量上比較，高濕度更有利於胭脂蟲的培育。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
在雲南熱帶、南亞熱帶、中亞熱帶三個氣候類型下的4個縣（市）放養胭脂蟲，應用生命表技術，研究各氣候類型下胭脂蟲的存活情況並分析出各氣候類型下胭脂蟲的主要致死因子，同時，採集各地培育的胭脂蟲樣品測定蟲體大小、懷卵量及重量，通過比較這些生物學指標，得出胭脂蟲的最適生區、次適生區及適生區，並以此為依據，對雲南省胭脂蟲的培育進行了區劃。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、整理國外對胭脂蟲的研究資料基礎上，首先從胭脂蟲的形態學、分類學、生物學特性入手，進而在實驗室內利用人工氣候箱，應用正交設計方法，設計了4種溫度、 2種濕度、 2種光照梯度的不同組合，通過測定胭脂蟲的孵化率、 1齡若蟲的存活率、 2齡若蟲至成蟲期存活率、種群趨勢指數、世代歷期、雌成蟲的大小、懷卵量等生物學指標，深入研究胭脂蟲在這些組合下的生長發育狀況，應用數理統計方法，分析出溫度、濕度和光照對各項生物學指標的影響，找出胭脂蟲適宜的室內培育條件，並為野外胭脂蟲的培育提供一定的理論依據。The nontoxic m. aeruginosa, however, had no negative effects on the growth of the water fleas
無毒微囊藻雖然不影響蟲體的生存，但影響其懷卵量和幼體產出。The main conclusions include : 1 ) among the non - biological factors, temperature is the most important factor that influence the development of the cochineal insect, the insect cannot finish life cycle under 15 associated conditions in spite of a few of egg can hatch, while at associated conditions of temperatures 20, 25, 30, the insect can finish life cycle, but comparing from the amount of eggs, generation tendency indexes and the sizes of the female adults, 25 associated conditions are the best
得出的主要結論包括： 1 ）在胭脂蟲的生長發育過程中，溫度是影響胭脂蟲發育的最主要因子，在15的恆溫狀態下，盡管胭脂蟲卵有少量孵化，但不能完成世代，而在20 、 25 、 30的恆溫下胭脂蟲能正常發育並完成世代。從培育的胭脂蟲雌蟲體大小、懷卵量及世代傾向等方面比較， 25的溫度最有利於胭脂蟲的培育。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
黑龍江魴資源量少的原因為：黑龍江魴為產弱黏性卵的魚類，對產卵場的要求較高。黑龍江魴的性成熟年齡較大（ 5齡） ，而且無論是絕對懷卵量還是相對懷卵量都較低，因此生殖力較低。黑龍江魴由於體形高而側扁，極易被捕撈。分享友人
