Forming a new cycle model of "mulberry-silkworm-bacterium-biogas"

"Formation of the cycle pattern of 'mulberry-silkworm-bacterium-biogas (fertilizer, biogas)', ie, the transformation pattern of mulberry mulberry, mulberry inoculum, biogas production from maternal biomass, and biogas fertilizer mulberry, and the gradual exploration of the intercropping of mulberry Interplanting, expanding the comprehensive use of mulberry gardens, and increasing economic value.” Recently, the villagers of Wanghe Village, Tengda Town, Qilian County, Yibin, Sichuan Province, spoke about the “Mulberry-silkworm-biogas” circulation breeding mode that the village is exploring. The tongue opened the voice.

Recently, the sun was flooded early in the courtyard of Linying, Wanghe Village, Tengda Township, Qilian County. The big sisters around the apron, the aunt holding her grandson, and the uncle sweating smoked. Seventy to eighty people ignored the heat of the sun. Around the 30-year-old sister Lin Ying, she kept asking.

Lin Ying said: "October last year, the project technicians took a simple shed in my backyard and used about 2 tons of waste mulberry stalks. After smashing, the sorghum seeds were planted inside and more than 1600 bags of bacteria were made. I watched every day, but at the time I didn't believe that the fungus bag made by Mulberry could grow the fungus. In February this year, the fungus grew up. You don't know that the smell of the fungus has been heard all the time. Get it on the market and sell it at 4 yuan to 5 yuan per kilogram, the other same fungus can only sell for 3 yuan, and the price of the fungus produced from the mulberry branch is high, but it is particularly easy to sell. It has collected about 1300 tons of fungus for two times. The income is more than 5,000 yuan. Last year, our family happily raised the silkworms of the four seasons, probably sold 18 bucks, and the income was more than 15,000 yuan. I did not expect that this mulberry branch used for burning fire could grow mycelia, but less than four. Months of time will be a few thousand dollars. You can pick up the fungus again in the last two weeks." Speaking of these, Lin Ying's big sister laughed and spoke up.

Hear some of these villagers still asked Lin Ying how the mulberry sprouts, and some villagers have gone to the Lin Yingjia fungus shed. "The original notice was to open this silkworm mulberry training meeting at 10 o'clock. I didn't expect some villagers to come at more than 8 o'clock. It was not so early." Wang Hecun village director Chen Qijun said.

At the training meeting, in addition to the current situation of sericultural technicians in combination with the sericulture industry in Tengda township and the technical needs of farmers, the farmers were specifically targeted for the cultivation and management of mulberry fields, the scientific rearing of silkworms, and the technical operating procedures for small silkworm symbiosis. As the first villager in the three-group village of Wang Hecun, who was identified as a comprehensive pilot project for the development of sericulture resources in 2010, Lin Ying also shared with him the "accidental" harvest he had achieved over the past few months.

For a long time people have limited understanding of the sericulture industry, that is, planting mulberry - sericulture - silkworm pupa - silk. In February 2011, Tenda Town cooperated with a silk company to develop the first mulberry branch development pilot project that successfully achieved economic value. Completely changing the concept of King Tengda and the hundreds of large silkworms in the village also convinced them that they could only be used for firewood and waste mulberry, and they could also “birth” money.

The development and utilization of modern sericulture resources mainly includes three aspects: First, the development and utilization of mulberry leaves. Mulberry is the main product of mulberry, it is rich in protein, carbohydrates, mulberry leaves also has hypoglycemic, hypolipidemic, anti-inflammatory, medicinal effect, can be made with mulberry leaves Mulberry green tea and mulberry oolong tea and other foods .

The second is the development and utilization of mulberry branches. Every year when mulberry trees are harvested during the winter season, a large number of mulberry branches are produced, which is extremely impressive. Using mulberry branches to cultivate edible fungi (mushrooms, black fungus, mushrooms, oyster mushrooms, etc.), the method of planting and cultivation is simple and easy, and the technology is mature. It plays an important role in improving the economic value of sericulture production.

The third is the development and utilization of mulberry. Mulberry contains about 85% moisture content, contains more sugar (Mulberry juice contains 10% sugar), contains organic acid 0.8% ~ 1.5%, also contains a certain amount of pectin tannin, mulberry and so on.

Tengda Town Wanghe Village currently has 936 mu of mulberry gardens. Each year, the average mulberry branches and mulberry tree piles (usually updated once every three years) per mu of mulberry trees weigh about 400 kilograms. Only Wang Hecun Mulberry Park can produce dry mulberry branches. (Including tree stumps) more than 400 tons. At the same time, in the sericulture process, more than 60 tons of dried leaf stems and residual leaves are still available. Mulberry twigs are rich in cellulose, hemicellulose, bioactive substances and other ingredients, and are very suitable for the growth of various edible and medicinal bacteria, such as mushrooms, fungus, ganoderma lucidum, mulberry yellow and so on.

Practice has proved that the recycling of mulberry leaves vigorously develops black fungus as the main mushroom mushroom, white fungus and rare fungus that are compatible with the production of edible fungi, which not only reduces the production cost of fungi, but also increases the added value of the sericulture to silkworm, Bacteria win-win. Wang Hecun began construction of a specialized silkworm house in September last year, and promoted the silkworm breeding mode to increase the quality and survival rate of silkworm eggs from the source; built a provincial energy saving platform and promoted the grid communities, saving time and labor and improving the unit time economy. Value; Vigorously introduce excellent varieties of mulberry trees, and newly develop 400 mu of mulberry fields to provide guarantee for breeding high-quality silkworms.

After listening to Lin Ying’s “accidental” experience, he looked at Lin Ying’s fungus shed and the villagers could not sit still. They talked about it, some said: This year to expand the mulberry garden, this thing really has to "get in the head"; some pull the technical staff said: The next time in my home also engage in a pilot.

It is reported that Tengda town has established a goal of building a "10,000 mu mulberry garden" within five years. The experimental development of mulberry branches is successful. The next step will be to promote this technology first in Wang Hecun and form "Mulberry leaves (silkworm)-branch, (Bacteria) - The circulation pattern of bacteria (fertilizer, methane).
