【摘要】 试验调查了大棚养蚕春、夏大蚕期与蔟中的温湿度变化,以探索有利于大棚养蚕的饲养技术与小气候调节技术。棚内温湿度变化对蚕茧产质量的影响比较分析表明,春期5龄后期和上蔟初期35～38.8℃的高温对蚕茧产质量有较大影响;夏蚕期棚内温度明显高于春蚕期,最高超过40℃,连续高温持续时间长,昼夜温差大。根据春、夏期不同的气候特点,春期大棚上蔟初期要重点进行降温排湿夏期重点进行降温。更多还原

【Abstract】 In order to search the techniques for silkworm rearing in scale and for the regulation of micro weather conditions in the green house with plastic film, the investigation on variation of temp. and RH in the green house during grown larvae and cocooning stages in spring and summer rearing were conducted. The results indicated that there was a great effect of high temp. between 35～38.8℃ on cocoon quantity and quality in spring, more higher temp. in the house in summer than that in spring, the highest temp. was over 40℃, and high temp. lasted longer duration and temp. difference between day and night was much bigger than that in spring. The key technique of silkworm rearing in green house was both to reduce the temp. and moisture in spring, and to reduce the temp. in summer.更多还原
