Guilin Academy of Agricultural Sciences has cultivated "Golden Dragonfly" which can be used to make body armor

On the 12th, in the silkworm house of the Guilin Academy of Agricultural Sciences, a golden silkworm cocoon was hung on the wooden buckle board. Tens of thousands of silkworm cocoons are gathered together, and the golden enamel is beautiful.

According to reports, this golden yellow silkworm cocoon is a new variety introduced and cultivated by the city. Through the silkworm mixed blood of the three countries of China, Japan and Vietnam, compared with ordinary silkworms, this silkworm silk is golden yellow. This is the first time in the history of mulberry sericulture in Guilin. Moreover, this golden silkworm cocoon is also a good surgical sewing thread material, and can also be used to make bulletproof vests...

The first time in Guilin’s agricultural history

According to the Xie Zhen Award of the technician of the Academy of Agricultural Sciences, the name of this natural color silkworm cocoon is “Cuihua H9”, which is the first batch of successful cultivation in our city. The biggest difference compared to ordinary silkworms is that the silk it spits is golden yellow.

"The cultivation process of this silkworm is not simple. First, we use our native silkworms to cross with Japanese varieties, and then cross the Vietnamese varieties to finally get them." Xie Zhen Award said that the silkworms currently being crossed In terms of varieties, golden yellow is the most stable. The city has introduced and cultivated since the beginning of 2017, and now the first batch of silkworm cocoons has been produced. This variety is more delicate than the common white silkworm. The breeding environment, temperature and humidity control are more stressful, and the timing of the cluster needs to be more accurate.

"This silkworm is very suitable for the climatic conditions of Guilin." Xie Zhen said that Guangxi belongs to the subtropical high temperature and humid climate. Guilin is located in the northeastern part of Guangxi. Compared with other parts of Guangxi, the climate is relatively mild, which is a favorable condition for breeding this species. In the future, the city will introduce more varieties, such as pink and purple cocoons."

"Golden 茧" has high economic benefits

Due to its noble yellow color, the economic benefit of "Citrus H9" is very high.

According to reports, the main component of silk is a kind of protein, and its protein composition is very familiar with human skin. Because of this, silk is called "the second skin of the human body." Silk is the raw material of high-grade silk garments. "Cassophila H9" is a natural yellow, which is environmentally friendly without chemical dyeing. On the other hand, in China, yellow has always been a noble and auspicious color, so silk made with natural golden silk will also have better economic benefits.

In addition to the difference in color, what are the characteristics of golden silkworm cocoons? According to reports, the fineness of natural colored silkworm cocoons (indicating the thickness of a wire) is finer, and the cohesive force (indicating the traction of a wire is stronger) is stronger. That is to say, colored silkworm cocoons are softer when they come into contact with the skin. After being put on the market, its quality may be more favored by customers, and the economic benefits are very promising.

At the same time, because the silkworm cocoon is finer and more cohesive than ordinary silkworm cocoons, the sewing thread for surgery is better than ordinary silk, and it will be more advantageous in medical use. Surprisingly, natural yellow silkworm cocoons are also a good raw material for making body armor.

Small silkworm cocoons have to make big articles

According to Li Jiawen, dean of the Guilin Academy of Agricultural Sciences, dean of the Guilin Branch of the Guangxi Sericulture Research Institute, and researcher Li Jiawen, Guilin has always had a tradition of mulberry sericulture, and in recent years, the economic benefits of fruits such as sugar oranges are high. Many farmers no longer grow mulberry sericulture. However, in recent years, Guilin has combined the silkworm industry with tourism and has been at the forefront of the region in terms of comprehensive utilization of silkworm.

"In April this year, the picking of mulberry fever in Guilin citizens was a typical example." Li Jiawen said that farmers planted fruit mulberry, in addition to selling fruit and raising silkworms, they also developed mulberry leaf noodles and mulberry wine by combining with tourism. Batch of tourism agricultural products.

"Next, we are going to make a big article for this small cocoon." Li Jiawen said that the introduction of the new "hybrid" varieties, one is to enrich the biological variety, and once again from the tourism, science and other aspects to develop the silkworm industry. Next, the Academy of Agricultural Sciences will not only promote the technology to farmers in the city, give technical support, but also make a bigger article around the color silkworm. If the relevant science popularization system is established and popularized among the citizens, in the season of picking mulberry, the citizens can not only enjoy the fun of picking, but also bring the colored silkworm cocoons back home to raise their own fun.
