After listening to Yang Fang's introduction, everyone nodded in recognition and affirmation of Yang Fang's rigorous work.
Experimental fields in so many areas are all conducting related experiments at the same time, and they last for several years. The investment and cost are definitely not a small amount. From this, we can also see the importance Haoyu Agriculture and Wu Hao attach to this technology.
This 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 will wait to see the materials you sent. Deputy Director Cheng said with a smile.
He turned around and looked around at the piles 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.
So, it still doesn’t 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 for papermaking. The fast-growing Populus euphratica is also good, and can also be used for papermaking and wood processing."
Yes, you have put forward higher demands for us. How could Wu Hao not understand what Deputy Director Cheng meant, and then said with a wry smile.
Haha, those who are capable 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.
Well, let me just say one thing: for the hundreds of millions of people in this large area of the northwest who are not yet wealthy, 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 first established 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 continued to speak.
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 is constantly increasing, 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 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 consumption of household paper has reached 320 million tons, of which our country’s household paper has reached 13.1 million tons. If converted into raw materials, it takes about four 20-year-old trees to produce one ton of paper.
.Then the world needs to cut down 1.28 billion big 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 big trees, which is equivalent to our country cutting down 52.4 million big trees every year.
35,000 hectares of non-renewable virgin forest need to be cut down.
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 difficulty in reconciling 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 endless cycle.
Fortunately, we are already aware of this problem and have proposed 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 paper making.
However, due to the relatively slow growth rate of trees, it generally takes ten to twenty years for a sapling to be planted and ready to grow. This cycle is too long.
Its growth cycle is far from being able to meet the growth of our human demand for paper.
Although we have also begun to try to use some fast-growing trees as the main tree species in artificial forests for papermaking, these fast-growing forests will also bring various problems.
Although they are said to be fast-growing forests, their growth rate is not too fast. For example, the fast-growing poplar varieties currently planted on a large scale in our country take five to six years to become mature. Moreover, there are many problems with fast-growing poplar varieties, such as
The most common problem for people in the north is 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. It not only absorbs a large amount of groundwater, causing the groundwater to dry up, but also easily causes soil compaction.
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 made 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 in terms of its flexibility, antibacterial properties, etc.
Paper.
What's more important is the regenerative nature 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.
