Applying high energy to the strike of the sericin of fresh cocoon layer in order to break the cross-section on the sericin by means of the high quantity and the shortest wave of γ-ray, and using electric mirror to observe it in scanning method, we can see clearly the layer structure of the sericin. There has been no precedent both at home and abroad. 1. To strike the cocoon layer by means of γ-ray 5000kr/50kr, we can see clearly that the sericin covered on the fibroin is divided into three layers'outside, middle,...

Applying high energy to the strike of the sericin of fresh cocoon layer in order to break the cross-section on the sericin by means of the high quantity and the shortest wave of γ-ray, and using electric mirror to observe it in scanning method, we can see clearly the layer structure of the sericin. There has been no precedent both at home and abroad. 1. To strike the cocoon layer by means of γ-ray 5000kr/50kr, we can see clearly that the sericin covered on the fibroin is divided into three layers'outside, middle, and the inner one. 2. The ratio of them is 4:3.5~4:2~2.5. 3. The outside one presents powdery particles with slightly vertical trace, the middle one presents horizontal mark and the inner one seems as if it reflected with the direction of crystalization. 4. As the silk manufacture industry has much to do with the outside sericin, we should pay treat attention to the breeds of silk worm, feeding, especially the mounting environment.

借助γ射线的高能量和极短波,应用高剂量冲击鲜茧茧层丝胶,使丝胶在丝素上横截断裂,电镜扫描观察,清晰地看到丝胶的分层结构。这种直接在茧丝上显示丝胶的自然分层状态,在国内外没有先例。 (一) 应用γ射线5000kr/50kr剂量冲击鲜茧茧层,得断裂丝胶,能清晰地看出被覆在丝素上的丝胶分成三层:即Ⅰ外围丝胶,Ⅱ中膜丝胶,Ⅲ内缘丝胶。 (二) 外围丝胶,中膜丝胶,内缘丝胶的比约为4∶3.5~4∶2~2.5。 (三) 外围丝胶现粉末状分布,微带纵痕,中膜丝胶现横痕,内缘丝胶现纵痕,似与结晶方向相呼应。 (四) 缫丝工程主系与外围丝胶打交道,因此在蚕品种,饲育环境,特别是上簇环境,应多加注意。

The present study was carried out in China on the changes of economic characters in the spring- and autumn-rearing silkworm va-reties. The results showed that cocoon weight, cocoon shell weight, cocoon layer ratio, cocoon filament weight, cocoon filament length and other economic characters of the current commercial varieties, especially cocoon weight and cocoon layer ratio, have been improved remarkably in comparison with those of the varieties popularized in the 1960-1960s. However, with improvement of the...

The present study was carried out in China on the changes of economic characters in the spring- and autumn-rearing silkworm va-reties. The results showed that cocoon weight, cocoon shell weight, cocoon layer ratio, cocoon filament weight, cocoon filament length and other economic characters of the current commercial varieties, especially cocoon weight and cocoon layer ratio, have been improved remarkably in comparison with those of the varieties popularized in the 1960-1960s. However, with improvement of the above economic values, the duration of the 5th instar and the amount of food consumed increased,whereas there were almost no improvement in digection rate and dietary efficiency .Therefore, special attention should be paid to the research on increasing dietary efficiency that may be realized by silkworm breeding, mulberry breeding, improvement of rearing techniques, etc.

本文调查分析了近二、三十年来,我国春用蚕品种和夏秋用蚕品种主要经济性状的变迁情况。结果表明,目前推广的蚕品种与五十、六十年代推广的品种相比较,茧层量、茧层率,茧丝量、茧丝长等主要经济指标都有了显著的提高,尤其是茧层量、茧层率的增长更为突出.但5龄经过和食下量也相应地增加,蚕的消化率以及饲料效率几乎没有提高。从而认为,在今后蚕品种改良过程中,应重视提高饲料效率的研究,并通过桑品种改良、饲育技术等途径,提高饲料效率,提高养蚕的经济效益。

Xinhang" and "Keming" were breeded by crossing with polyvoltine race ane hypersilkgenerous race.Their offspring were reared in the conditions of temperature 29-32℃ and RH 85%, inbreeding was used continuously 7 generations. In order to raise the raw silk percentage, some batches those cocoon shell, weight, reelable cocoon rate, cocoon shell ratio, cocoon filament length, cocoon filament weight and reelability are excellent were selected for generation passage.

新杭、科明是以含有多化性血统及多丝量品种杂交固定而成.培育中,采用温度29—32℃、相对湿度85—90% 、连续7代近亲交配.通过提高茧层量和上茧率,相应提高茧层率、茧丝长和茧丝量,并选择解舒率高的蛾区继代,以达到提高出丝率的目的.为了使强健性和数量性状之间平衡发展,在早代加强数量性状的提高,在中期控制数量性状选择强度.同时,选育中调查蚁蚕绝食72小时存活率、饥饿后食桑能力的恢复、2龄起蚕绝食生命时数及5龄饷食到上蔟后96小时高温冲击的发蛾率等.证明对检验蚕品种的强健性和加速新品种的育成是有效的.
