After listening to Yang Fang's introduction, everyone nodded in recognition and affirmation of Yang Fang's rigorous work.
Experimental fields in so many regions are all conducting related experiments at the same time and last for several years. The investment and cost involved are definitely not a small amount. From this, we can also see the importance Haoyu Agriculture and Wu Hao attach to this technology, which further proves the safety and reliability of this technology.
It seems that you are well prepared in this regard. Okay, I won't ask any more questions and wait to see the materials you sent. Deputy Director Cheng said with a smile.
He turned around and looked around at the masses of Super Haloxylon ammodendron, and then said to Wu Hao: "Although this Super Haloxylon ammodendron is good, it also has shortcomings, that is, it is economically weak and cannot directly increase local income. Although it can Mixed with Cistanche deserticola, but the efficiency is low and it is difficult to scale up.
Therefore, it still does not have the conditions for large-scale promotion. "
Speaking of this, Deputy Director Cheng sighed and said: "This is also the most troublesome issue for us, that is, how to estimate the income of local people while carrying out ecological protection.
I think your moso bamboo is very good. It can be used as some engineering building materials, bamboo products, handicrafts, and can also be used to make paper. The fast-growing Populus euphratica is also good. It can also be used for paper making and wood processing. "
Yes, you are setting higher demands on us. How could Wu Hao not understand what Deputy Director Cheng meant, and then said with a wry smile.
Haha, those who are able work hard, who allowed you to have such advanced technology. Deputy Director Cheng laughed, then looked at Wu Hao and said seriously: "I won't tell you about other economic benefits and social benefits. I will just say one thing, for the vast area in the northwest that is not rich enough to go to school. Hundreds of millions of people, you can’t just sit back and watch indifferently.”
There is a hint of kidnapping in these words, but what Deputy Director Cheng said is also a fact, that is, the current economic value of these drought-tolerant plants is not obvious enough, and it is indeed impossible to help these hundreds of millions of people get rich.
In fact, we took these into consideration when we started the project. Shen Ning, who was accompanying Wu Hao, said.
Wu Hao glanced at Shen Ning, then nodded slightly to indicate for her to continue speaking. Shen Ning understood and immediately continued to preach.
The first is the papermaking industry you mentioned. Except for a small part of the paper we use currently, which is produced by recycling waste paper, most or even the vast majority of it is newly made paper, and among the newly made paper The most commonly used raw material is trees.
Among the trees used, except for a small number of trees in artificial forest farms, a large part of the others actually rely on the concept of logs.
Because the amount of paper we humans need continues to increase, and the growth rate of artificial forests is slow and the number of trees they can provide is very limited, so most of the raw materials needed for paper still rely on the felling of natural forests.
Although this kind of indiscriminate deforestation is basically invisible in our country and some developed countries, it does not mean that they do not exist, but have been transferred to developing countries and third world countries.
According to statistics, the global household paper consumption reaches 320 million tons, of which our country’s household paper reaches 13.1 million tons. In terms of raw materials, approximately four 20-year-old trees are needed to produce one ton of paper. Then the world needs to cut down 1.28 billion trees a year, which is equivalent to cutting down 850,000 hectares of non-renewable virgin forest every year. Our country alone needs to cut down 52.4 million large trees, which is equivalent to our country needing to cut down 35,000 hectares of non-renewable virgin forest every year.
Regarding how to save paper, this is an important issue in environmental protection. Although people's environmental awareness is gradually strengthening under the strong advocacy of various countries and societies, there is still a problem that is difficult to reconcile between the strong market demand and the severe environmental situation. The contradiction is that people need paper in their lives, and to use paper, they need to cut down trees. This seems to have fallen into an incomprehensible cycle.
Fortunately, we are aware of this problem and have come up with many solutions. For example, we advocate saving paper, adopting paperless office methods, increasing the recycling and utilization rate of waste paper, etc.
Another step is to increase the planting area of artificial forests and use artificial forests to channel natural forests as the main raw materials for papermaking.
However, due to the slow growth rate of trees, it usually takes ten to twenty years for a sapling to be planted and mature. This cycle is too long.
Its growth cycle is far from being able to meet the growth of our human paper needs.
Although we have also begun to try to use some fast-growing trees as the main tree species in plantations for papermaking. But these fast-growing forests also bring a variety of problems.
Although it is said to be a fast-growing forest, their growth rate is not too fast. For example, the fast-growing poplar varieties currently planted on a large scale in our country also take five to six years to mature. Moreover, there are many problems with fast-growing poplar varieties. For example, the most common problem among northern people is the problem of flying catkins. Catkins flying all over the sky are not only easy to cause fires, but also easy to pollute the environment and cause many asthma and bronchial diseases.
In addition, fast-growing poplars have poor resistance to diseases and insect pests, and they have relatively high requirements for the natural environment. It is difficult to survive and grow in harsh environments such as the Gobi desert in the northwest.
Then there is our fast-growing eucalyptus. This tree species has been banned by our country because it is too harmful to the environment. Not only does it absorb a large amount of groundwater, causing it to dry up, but it can also easily lead to soil hardening, and dead leaves of fast-growing eucalyptus can easily pollute groundwater.
Finally, the fast-growing eucalyptus tree is very domineering. Its strong root system will absorb nutrients from the surrounding soil, making it difficult for surrounding plants to survive.
Therefore, experts and professors such as your Forestry Research Institute and Professor Zhang and Professor Huang have actually been exploring new plantation varieties suitable for papermaking.
Fortunately, technological innovation has given us hope. With the development of technology, the maturity of bamboo pulp papermaking technology has provided a new solution to the needs of human paper.
With the huge technological breakthroughs in modern bamboo pulp papermaking technology, the quality and quality of its household paper has become comparable to high-end wood pulp paper. Even bamboo pulp paper has greatly surpassed traditional wood pulp paper in terms of flexibility and antibacterial properties.
What’s more important is the regenerative and rapid growth characteristics of bamboo, which is simply the best raw material for papermaking. “Replacing wood with bamboo” will be the mainstream trend in the papermaking industry in the future, and it is also the general trend of environmental protection.
