This environmental pollution is becoming more and more serious, and human beings have begun to focus on the development of renewable resources and the use of other resources. The use of orange stalks in rural areas has been low, people mostly use them for burning, and too many orange stalks can also hinder the cultivation of farmland. After years of development, the technology of using orange stalks, straw and other plants to make paper in China has tended to mature.
Even though the orange stalk is very rough and the surface will be prickly, we just need to use the plant fibers in it to make paper, as long as the plant fibers are better protected and can be successfully separated, we can make smooth paper. <>
The principle of papermaking is to use plant fibers, the fibers are intertwined and entangled, and there is good adhesion, and all the plant raw materials are gathered into a thin piece after the orange stalk is pulped, and the plant fibers are irregularly intertwined and entangled, and the initial appearance of the paper emerges. The dissociation point of orange stalk fiber is higher than that of wood pulp, and the dissociation point of orange stalk fiber is higher than that of wood pulp, and the orange stalk needs to remove higher lignin to make pulp. In addition, traditional pulping technologies such as alkali processing, high temperature and high medicine will cause damage to the orange rod fiber, resulting in a decrease in its fiber length, damage to strength, and poor quality of pulp.
After more than ten years of development, my country has now greatly improved the technology of using cabinet rods to make paper, and has invented some new methods. If the newer equipment is adopted, the grinder is used to replace the mower, and the orange rod filament and impurities are removed higher, so that the pass rate of grass flakes is greatly improved. And with the help of these scientific and technological technologies, even rough orange stalks are able to produce very smooth and delicate paper, and they even produce napkins for us.
It is also effective in protecting the environment and making full use of resources, but sometimes the paper may take on a natural wood color because it is not bleached. Don't choose other tissues because of this, we should support this kind of environmentally friendly and energy-saving paper towels.

Although the straw is very rough, the straw paper is very smooth, because the paper is not made from this object alone, but is mixed with other substances.
-
Although the straw is very rough, the process of turning the straw into paper is very complicated. It takes more than a dozen processes in the middle to make the paper, and the paper is very smooth.
-
The straw is rough because it is original and unprocessed, but when it is processed into paper, it needs to go through a cumbersome process, polish it into powder, and then screen and extrude.
-
This is because in the processing process, there are multiple processes that can make the raw material smooth, after all, it is too rough to write.
-
The reasons why you don't use straw to make paper are as follows:
Because the cost is too high, ** is not supported, the price per person is now 80 yuan is the cheapest, a day in 100 acres of fields can receive about 5,000 pounds of bellflower, if you go to collect the price is not high enough, others will not spend that thing to carry, and then the country has not issued a formal policy, no country's first businessman does not dare to take that risk.
Uses of straw:
1. Straw returning to the field is currently the most direct and easiest way to implement the utilization. Baoyou travel to the state, including direct return to the field, high-temperature composting, over-belly return to the field, etc.
2. Straw feed corn straw is a good raw material for the development of animal husbandry. After being used as feed, its by-product manure is a good raw material for fertile fields. It is divided into silage, ammoniated feed, etc.
3. Straw biogas Compared with manure biogas digesters, straw biogas digesters are not easy to rot, have a high gas production rate, replace coal and electricity, and provide energy for rural cooking and heating.
4. Straw production of edible mushrooms, corn straw can be fermented to produce edible mushrooms such as oyster mushrooms, chicken leg mushrooms, mushrooms, etc., and the waste materials can be used as farm fertilizer to return to the field. <>

Straw is a hot issue for summer and autumn harvesting every year. How to deal with straw is not only a headache for farmers, but also a headache for the responsible departments in various places. Until a practicable establishment is possible, the authorities can only ban burning and pull banners everywhere.
But in recent years, to put it simply, relevant agricultural colleges and farmers have agreed that straw return to the field is a problem. University researchers believe that fertility after returning to the field is sufficient, while farmers believe that it is more economical. So is the return of the straw back to the field really perfect in execution?
Not necessarily. This is called the two-sided nature of things. Today, let's talk about the shortcomings of the return of straw.
The utilization of straw is based on decay, but the degree to which corn straw is crushed by the direct straw thresher is still much worse, and even some straw is not broken, so the decay rate of straw directly into the farmland is very slow, which also means that the straw can not be used directly, but, as mentioned earlier, the impact of broken straw in farmland planting is still very large, which is also because broken straw is not like rotten farmhouse fertilizer, which is more broken through deep fermentation. Straw is of different lengths in the field, affecting tillage. At the same time, it is prone to running water, and the water loss is serious, which also leads to planting.
Corn stalks themselves are a place that is easy to induce pests, and there may be a large number of insect eggs and germs in it, which also leads to the transfer of mycelial spores and insect eggs of pests and diseases to the farmland after the straw is directly returned to the field, and the outbreak occurs again the next year, causing more pests and diseases.
These are some of the problems existing in the return of straw to farmland, but the core factor of these problems is that the straw is not really decomposed. For completely decomposed straw, many of the above problems can be avoided, such as the straw rots and scatters into the farmland, which will not cause the farmland to run wet, and the natural seedlings will also break. In addition, straw returning to the field actually has many benefits, such as improving soil structure, increasing soil fertility, and reducing the amount of fertilizer.
Some of them are analyzed on the basis of our full understanding of the advantages and disadvantages of straw return. Look at the problem objectively, don't look at the problem too one-sidedly, because choking on eating is unacceptable!
-
Fertility declines, plants burn roots, plants die, yield reduction, plant diseases, and other things will affect farmland income, so we must take them seriously when crushing straws, and we must crush them thoroughly, only in this way will they not affect the growth of crops in the next season.
-
When it comes to the benefits of not burning straw, there are naturally there, first of all, it will not cause pollution to the atmosphere, and secondly, it will reduce the loss of farmers, because some people will burn the grain that has not yet been harvested when burning, and the straw can also provide nutrients for the land after crushing and decomposing.
-
If the straw is not crushed well, it will cause insufficient purity and rough and uneven surface, resulting in a reduced effect of use, which will affect sales**.
