A luxury business helicopter was hovering over a huge forest in the desert. Wu Hao and Zhang Jun, who were officially here for inspection, were seated in the helicopter, accompanied by Shen Ning and drought tolerance project leader Yang Fang.
Although the helicopter was well-sealed, the huge noise from the propellers and engines was still transmitted to their ears through the sound-isolating headphones.
This is also the reason why he is unwilling to build a helicopter. No matter how luxurious it is, it is still not as comfortable as a fixed-wing business jet. Although it is very convenient, it has huge advantages, especially in short-distance transportation.
But similarly, it also has many disadvantages. The riding experience is not good on one hand, and on the other hand, its accident rate is a little high.
Although the technology of helicopters is very mature, it encounters too many unexpected situations during flight, and a slight mistake may cause the aircraft to crash and kill people.
There are too many such examples, the most famous of which is probably the old rice basketball superstar.
But don’t worry so much, after all, this thing is still a small probability event, and it doesn’t hurt to ride it a few times by chance.
Is this forest area full of bamboo? Wu Hao couldn't help but ask as he looked at the huge oasis below.
Shen Ning held the earphones, then nodded at Wu Hao and said, "Yes, this large area here and that area are all bamboo, and the total total is about 22,000 pieces of wood.
Normally, there are about 5,000 to 8,000 bamboos in one acre of bamboo forest, but this is a traditional bamboo forest that has been grown for many generations. The large bamboo forest below us is artificially planted and cultivated, so its density is relatively high. Low, there are about 2,000 bamboos in one acre of land. After all, this is only the third year, and the number of new bamboos is limited. In a few years, the number of bamboos in one acre of land can reach 4,000 to 6,000. It's normal level.
If this is a humid area in the south, with sufficient water and soil nutrients, the number of bamboos per acre will reach 10,000.
At present, our preliminary estimate is that there are almost 44 million bamboos in this large bamboo forest below."
So many! Hearing Shen Ning's introduction coming from the earphones, Zhang Jun couldn't help but asked in surprise: "How many bamboos did you plant?"
In fact, we mainly planted bamboo roots at the beginning, and almost 1.3 million bamboo roots and related bamboo seedlings were planted here. In three years, the number increased by almost 33 times. Shen Ning introduced with a smile.
Zhang Jun couldn't help but open his mouth: "Isn't this growth rate too fast?"
Yang Fang said with a smile: "Actually, this speed is not too fast. It is true that we have made relevant edits and modifications on the breeding and growth speed of bamboo, but the breeding speed of bamboo itself is very fast. One bamboo can produce about Three to five bamboo shoots grow out, and the bamboo roots can grow about one to two meters a year.
The more bamboos grow, the more bamboo roots will grow. The more bamboo roots will grow, the more bamboo shoots will sprout and grow on the bamboo roots.
Under normal circumstances, these 1.3 million bamboo roots and bamboo seedlings can grow approximately 15 million bamboos in these three years.
This speed should be said to be fast enough in nature, but it still cannot meet our requirements. The main reason is that the natural conditions in the area next to the desert are too harsh, and bamboo must be given stronger vitality, including the ability to reproduce.
To give bamboo stronger vitality, the first and most important thing is to modify its root system. We know that basically all drought-tolerant plants that can survive in the area next to the desert have very developed root systems.
For example, Populus euphratica, a representative species in the desert, has a root system that can reach a length of one hundred meters and a depth of more than twenty meters. It can penetrate deep into the aquifer underground in the desert, thereby absorbing water and nutrients from the deep soil.
The bamboo root system is basically one to two meters long, and the longest is only about eight or nine meters, while the depth can only reach one to two meters, or even shallower.
This is obviously not possible in desert areas. Let’s not talk about whether the depth of one to two meters can absorb water and nutrients from the sand for the bamboo. It is said that this depth is too shallow, making the grip of the bamboo roots weak. If there is strong wind
, these bamboos may be uprooted.
Therefore, we need to modify and edit the root system genes of bamboo to make its root system grow faster, become more developed, and be able to penetrate deeper into the ground.
After our improvements, the growth rate of bamboo roots can reach three to five meters per year, which has been increased by almost three times. In addition, the length of bamboo roots can also grow longer, with a maximum length of thirty to four meters.
About ten meters, it can penetrate into the ground to a depth of about fifteen meters, thereby absorbing water and nutrients from deep sand or soil.
Moreover, we have also strengthened the root ends of bamboo to make its terminal fibrous roots more developed, which can absorb more water and nutrients and support the rapid growth of bamboo.
The growth rate of bamboo shoots has also been greatly improved. Basically, eight or nine bamboo shoots can grow every spring, summer and autumn, seven or eight bamboo shoots can grow in winter, and twelve to eighteen bamboo shoots can grow in almost a year.
bamboo."
Speaking of this, Yang Fang tempered her expectations and said with a smile: "Of course, so many bamboos may not all survive. The sprouting rate and survival rate of the entire bamboo shoots are related to the natural environment. If the temperature during the sprouting growth stage is too low, it will be too cold."
Excessive drought will affect the germination rate of bamboo shoots.
The nutrients in the soil are also related to the growth rate of these bamboos and bamboo shoots. If the nutrients are too poor, it is likely to affect the growth rate and growth quality of the bamboos.
A large bamboo forest like this here actually grows so lush after our artificial intervention. After planting, we irrigate it with water every few days to ensure that it has sufficient water during its growth and rooting stage.
And we will also spread fertilizers in the air to increase the strength of the soil, so that they can grow faster and grow more vigorously."
Speaking of this, Yang Fang pointed to the bamboo forest not far below that was not as good as here and said to a few people: "The bamboo forest over there was grown by us without artificial intervention. Therefore, the experiment
Its growth status in the environment next to the desert without artificial intervention.
We can see that the bamboo forest over there is obviously not as lush as here, and the plants are not as dense as here. The number is almost only half of that here.
Moreover, the length of the plants and the diameter of the bamboo trunks are not as high and thick as those achieved through manual watering and fertilization, but the difference is quite obvious."
