The summer harvest has come, what to do with the waste straw?

Centralized collection, usually by people from paper mill related manufacturers, is used to make paper and other goods, if the quantity is small, it can be buried in the ground, using moist soil to break down straw and provide nutrients.

Waste straw can be fertilizer, feed, base material, fuel and raw material, all of which can make straw achieve the purpose of waste utilization.

Make a fermented feed.

Straw micro-silage is to add microbial high-efficiency active bacteria to the straw, put it in a sealed container (such as cement pool, fermentation tank, fermentation bag) for storage, after a certain fermentation process, the straw becomes one of the feeds that herbivores like to eat.

Comprehensive utilization technology of corn straw.

Straw is a valuable renewable resource, and the technology of returning straw to the field is vigorously promoted.

It is a simple and easy "project to enrich the people". In order to achieve a new breakthrough in the comprehensive utilization of straw and the ban on straw burning, the following technical suggestions are proposed.

1. Recognize the hazards and raise awareness.

Burning straw not only endangers people's lives and property, but also causes waste of resources and environmental pollution. Therefore, it is necessary to resolutely prohibit it.

2. Rely on the comprehensive utilization of the masses.

Straw is a valuable renewable resource, all relevant departments at all levels and the city's cadres and masses should actively promote straw directly returned to the field, over the belly to the field, straw feed, biological fungus system, orchard covering, edible fungus production and other multi-channel, multi-field comprehensive utilization technology, so that the comprehensive utilization of straw work has truly become a "project to enrich the people".

1) Straw is returned directly to the field.

The direct return of straw to the field is the main way to fertilize the soil, and the direct return test for three consecutive years has proved that the soil organic matter is increased, the total nitrogen is increased, the wheat yield is increased by 45 kg, and the corn yield is increased by 56 kg. Therefore, it can be seen that straw returning is one of the measures to fertilize the soil, improve the soil and increase the yield.

2) Return to the field.

With the adjustment of the structure of agricultural industrialization, the scale of the city's aquaculture industry continues to expand, and returning to the field not only solves the feed resources but also can obtain organic fertilizer with complete nutrients.

3) Construction of biogas digesters.

The construction of biogas digesters in rural areas can not only effectively make full use of straw, but also save energy, saving more than 500 yuan per household in fuel and lighting expenses.

4) Biological bacteria pile straw returning to the field.

Biological fungus compost straw is a new way to transform straw, which can make straw ferment quickly, and can convert straw into high-efficiency and high-quality organic fertilizer within 20-30 days. Generally, the organic matter can reach 30-60%.

5) High-temperature composting.

High-temperature composting is also a measure to transform straw, which is collected together in the autumn and stacked at high temperatures in the rainy season to accumulate high-quality compost. It can be used as the base fertilizer of various crops, saving labor and labor, and can obtain pollution-free fertilizer with complete nutrients.

3. Returning straw to the field is beneficial to the country and the people.

The biggest beneficiary of the comprehensive utilization of straw is the farmers themselves, so it is necessary to establish a new concept of scientific utilization, benefiting the country and the people, and enhancing the initiative of straw burning ban and comprehensive utilization.

We just did a research project on agricultural straw treatment. In fact, the second floor says a lot, but it is also relatively empty, and now there are very few technologies that can really be matured and practicalized to promote on a large scale, and they can't solve any problems. Foreign countries are directly crushed and returned to the field, and the current national opinion is also beyond this direction of development, and Jiangsu Province is also the first to establish local regulations as a provincial and ministerial unit.

You can talk about it when you have time.

How can there be no place to use it? We all use straw as a raw material for biogas digesters, so you can try it too!!

Isn't it possible to make paper? Papermaking is good.

Before the wheat is harvested, the wheat straw is pulled back and the mud is "pressed" (wiped on the roof) in order to prevent rain, we make up the mud once every three years at most, and we do not have many kinds of wheat, and one or two acres of wheat straw are still very useful. Now it's different, some houses are abandoned, and all that is left can be sold for some money. Corn stalk is the most optimistic feed raw material for large farmers.

Because of its high sugar content, <> is often used as the main material of saccharified feed by large cattle and sheep farmers; Rice and wheat straw will generally be evenly sprinkled in the ground directly by the tractor rotary tiller, the straw in the ground is to fertilize the land improvement, we mainly plant corn and wheat here, now the wheat straw, the harvester in the field directly into a bundle of paper, corn straw, in the field harvester directly crushed, the cultivator turned into the ground as fertilizer. (Shandong, now the environmental protection requirements are very strict, prohibiting incineration.) Hello everyone, I'm an old farmer planting angelica.

In the past, we would make wheat straw flour into pig food, mixed with barley and barley to feed pigs, so that the pigs would be very healthy and the meat would be delicious, unlike now it is all feed or leftovers from restaurants, which has no taste at all and is very unhealthy. If the straw is not left for other purposes, the straw is directly broken and broken, and it is not necessary to deal with it again, it is directly sprinkled in the ground, and the land can be planted directly to plant autumn grain, and the straw is buried in the ground as fertilizer. That's how our wheat is harvested.

Straw is a major economic pillar in the local area, and the price of the folded ear root is also OK, the general wholesale price is between 2 and 4 yuan, and the annual income of planting an acre of folded ear root can be four or five thousand yuan, and some can reach six or seven thousand, so the farmers have a high enthusiasm for planting the folded ear root. In Jiawang District, Xuzhou, Jiangsu, all the wheat has been harvested here, and the villagers are happy to have a bumper harvest. Now the state attaches great importance to the treatment of wheat straw, and must not be burned, which is very harmful to the pollution of the atmosphere and to the human respiratory organs.

Straw heaps are fermented.

Straw piling is the process of using a series of microorganisms to mineralize and humify organic matter such as crop straw. The carbon-to-nitrogen ratio of organic matter can be narrowed through composting, the nutrients in organic matter can be released, and the spread of germs, insect eggs and weed seeds in the compost material can be reduced. Therefore, the decomposition process of compost is not only the process of decomposition and resynthesis of organic matter, but also the process of harmless treatment.

The straw can be completely put away and used as food for the animals. It can also be incinerated to change the soil quality of the land and eliminate some pests in the soil.

After the autumn harvest is completed, the straw all over the ground is cleaned by professional machines, and now there are people who harvest straw, they are all reused, made into other fertilizers, this does not have to worry.

After the autumn harvest is completed, the straw can be collected after drying in the sun and used for fire or fertilizer.

Our straw resources are very rich, there are about 1 billion tons of straw every year, and straw now has 5 best utilization directions, that is, straw fertilizer, fuel, base material, raw material and material. Straw carbonization is a more popular way.

Straw carbonization machine is a device that can make loose straw into charcoal through drying, dry distillation, cooling and other processes in charcoal making equipment.

The straw carbonization machine can carbonize 3-10 tons of straw per hour on average. We calculate according to the processing capacity of 5 tons, the average ton of straw charcoal is the average hourly carbon ton, and the market price of straw charcoal is 900-1500; We calculate it according to 1200 a ton. With an average of 1,500 per hour, you can work continuously for 24 hours a day, and your comprehensive income is 36,000 a day.

Straw can basically be obtained for free, minus the cost of transportation, the straw used a day is 30 tons, each ton is calculated according to 200, the cost of straw is 6000, and there is an average of 30000 income per day, and the straw carbonization uses the gas heating produced by its own carbonization, removing some labor costs, and it is basically about 29000 a day.

In rural areas, in order to protect the environment, in recent years, straw burning ban and straw returning to the field have been implemented, many farmers have caused a series of planting problems due to poor treatment methods, which are not only not environmentally friendly, but also cause serious pests and diseases, and even reduce harvest and yield. Later, many farmers preferred to pile up the straw in the field to rot rather than return it to the field, which not only affected the environment, but also caused waste. In rural areas, these straws that are unwilling to be returned to the field can be used, which not only protects the environment, but also increases farmers' income and turns waste into treasure, which is a very meaningful cause.

In rural areas, straw can develop in four aspects.

First, straw storage becomes winter forage fodder. After the crops are harvested, the straw left behind, such as straw, wheat straw, corn straw, dried sweet potato vine, peanut grass, etc., is bundled and stored after being freshly dried and air-dried, which is a high-quality forage feed for animal husbandry in winter. This is also a kind of solution to the contradiction caused by the transformation of straw to the field, and it has become a livelihood cause of ecological and environmental protection.

Second, it can be processed into smoke-free artificial heating fuel. At present, many farmers in rural areas use weeds and straw to process smokeless fuel charcoal, which solves the problem of winter heating in places where there is no heating, and is also a good way to start a business in rural areas.

Third, packaging materials can be manufactured nearby. Now the economy is very developed, and product packaging materials are in short supply. Rural straw is a high-quality raw material for manufacturing product packaging materials.

In rural areas, this processing and manufacturing project can be selected to convert farmers' waste straw nearby, which not only increases farmers' income, but also protects the ecological environment.

Fourth, it can be processed into daily necessities. Due to the development of science and technology, people turn wheat straw and other agricultural waste into colorful daily necessities through compression and dyeing. The realization of this project, the use of large amount of products, economic and environmental protection, and high economic benefits, is a promising good project for rural entrepreneurship.

Dear, hello, I'm glad to answer for you, rural cooperatives can be the best straw, generally collected nearby.

Questions. Okay thank you.

You are welcome.

Straw can be carbonized to make straw charcoal, which is widely used, soil improvement, steelmaking or replacing coal for heating; The average is about 1,000 yuan per ton; Henan Beigong is a straw carbonization furnace, you can learn about it.

Straw carbon can be used as fuel, instead of coal, and can also be used to process carbon-based fertilizer.

Straw carbonization can use the continuous carbonization furnace produced by Beigong Machinery Co., Ltd., continuous feeding and carbon output, low production cost, and economic benefits without subsidies.

The continuous carbonization furnace carbonization straw step is to crush the straw first, and then if the moisture is relatively large, it needs to be matched with a drying furnace, first drying and then carbonization, and then the output is straw toner, and then the molding machine can be used to process carbon rods or carbon balls as needed. Straw carbon can also be used as a raw material for charcoal-based fertilizer.

Straw can be fermented into feed, fermentation beds can be made, and waste can be turned into treasure.

Recipe 1800 + 800 + 800 + 800 + 800 + 800 + 30kg + 30kg + water in Nongle fermentation bed.

Recipe 2Peanut shell (simple crushing) 1000 + wood chips 1400 + Nongshengle fermentation broth 30kg + water.

Bedding composition and material selection principles of fermentation beds:

The bedding should be fresh, non-spoiled, non-toxic, no miscellaneous soil, no peculiar smell of all kinds of crop straw, can also be fresh. Such as rice husks, sawdust, rice bran, wheat husks, corn, corn stalks, peanut seedling husks, potato seedlings, various weeds, wheat straw, distiller's grains, edible mushroom bran and other dry, fresh, crushed, crushed, crushed can be. The water used is unpolluted groundwater.

The principle of making finches in the selection of bedding is: inert (crude fiber is higher and not easy to be decomposed) raw materials, hardness, there is an appropriate amount of nutrients such as energy, the inertness and hardness of various raw materials are sorted as: sawdust bran powder (the substance after rice straw is crushed) cottonseed husk coarse powder peanut shell cotton stalk coarse powder Other straw coarse powder, the more inert the raw materials, the more nutritious feed such as rice bran or wheat bran should be added, to ensure that the carbon and nitrogen ratio of the bedding is about 25 1, otherwise all inert raw materials such as sawdust are used, The permeability is not very good, the fermentation is slow, there are no particles or large coarse bedding, and the fermentation heat production is earlier and slower than the pure draft, so it is necessary to add an appropriate amount of straw powder or rice bran during fermentation.

Methods for calculating materials:

Livestock (pigs, cattle and sheep) fermented mattress material: generally build 60-80cm thick, thin in the south, thick in the north, calculate the corresponding thickness, the weight of the bedding per square meter, and then calculate the total amount required for the total area.
