用葡萄糖喂蚕好

《内江科技》 2001年第3期47-47,共1页
用葡萄糖喂蚕不仅产量高,而且质量好,方法也很简便。按1:5的比例把糖和凉开水兑好,喷洒桑叶即可。蚕吃了喷洒葡萄糖桑叶后,不仅发育良好,生长快,发病率低,而且茧大层厚,比吃不喷洒葡萄糖桑叶的产量提高40%以上。

Through field observation and lab analysis, 13 agronomic traits, including plant height and effective branching number per plant, etc., of 207 faba bean (Vicia faba L.) germplasms saved in Crop Middle-term Genebank ... Through field observation and lab analysis, 13 agronomic traits, including plant height and effective branching number per plant, etc., of 207 faba bean (Vicia faba L.) germplasms saved in Crop Middle-term Genebank of Hubei Province were evaluated, moreover, the identification on the disease resistance and the quality was carried out on parts of germplasm resources. The results showed that the faba beangermplasm resources in Hubei Province were abundant, the variation range of agronomic traits like the growth period, plant height and 100-bean weight, etc., was great, and the range of choice was wide. In the aspect of quality, there were 9 germplasms withthe content of crude protein higher than 30%, and the variation range of amylose content in total starch was large, which provided excellent sources of parents for breedinq hi.qh-quality faba bean varieties in Hubei Province. 展开更多

In Turkey, studies devoted to conservation of animal genetic resources are carried out by general directorate of agricultural research (TAGEM) under the ministry of food, agriculture and livestock. There are 9 sheep and 3 goat breeds and 3 silkworm lines which produce animal fiber have been put under conservation by TAGEM since 1996. A considerable amount of these genotypcs are preserved as in situ. The success of this conservation method is directly associated with economically making the best of these genotypes which are preserved. Hence, making the most of fiber production alongside meat and milk production would make a great contribution to their conservation. For this purpose, determining production biology of mohair and textile features of Ankara goats at present, determining all features of traditional items (especially handicrafts) made of fibers obtained from these breeds and lines which have been put under protection and creating new usage areas have been issues worked upon. Along with this, in recent years, just as the world, especially EU countries, interests and studies for issues such as organic animal fiber production, rural development and geographical indications have been increasing in Turkey, as well. In the near future, this situation is supposed to have a great effect on increasing of animal fiber production in a positive way, too. Hence, to benefit more effectively from fibers obtained from these breeds which have been put under protection will make a great contribution to be protected by breeders. For this purpose, there will be studies in the near future devoted to determining production biology of fiber and determining features of textile in breeds and lines and increasing the consumption of products to be obtained from these fibers as well as Ankara goats. Therefore, in this article, it was emphasized on the more efficient of ways to be benefited from fiber production in these breeds and lines under protected. 展开更多
