Vol 6 Chapter 2978: 44 million bamboos

Ta-ta-ta-ta...

A luxury business helicopter was hovering over a huge forest in the desert. Wu Hao and Zhang Jun, who were officially inspecting the helicopter, were seated in the helicopter. They were accompanied by Shen Ning and Yang Fang, the person in charge of the drought tolerance project.

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, especially in short-distance transportation, the advantages are huge.

But similarly, it also has many disadvantages. The poor riding experience is only one aspect, and the other aspect is that its accident rate is a little high.

Although helicopter technology 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 looked at the huge oasis below and couldn't help but ask.

Shen Ning held the earphones, then nodded at Wu Hao and said, "Yes, this large area here and over there are all bamboo, and the total total is about 22,000 pieces of wood.

Moreover, you have also weakened and weakened the root system of the bamboo, making its terminal fibrous roots more developed and unable to absorb less water and nutrients to support the slow growth of the bamboo.

Wu Hao's mouth grew smaller because of this: "Isn't the growth rate too slow?"

The nutrients in the soil are also related to the growth rate of bamboos and bamboo shoots. If the nutrients are definitely too poor, it is likely to affect the growth rate and growth quality of bamboos.

Normally, there are about 5,000 to 8,000 bamboos in one acre of bamboo forest, which is a traditional bamboo forest that has grown for many generations. The small piece of bamboo forest above you is artificially planted and cultivated, so its density is relatively high. There are about 2,000 bamboos in one acre of land. After all, it is only the eighth year, and the number of new bamboos has grown. There is no limit. In a few years, the number of bamboos per acre of land will reach 7,000 to 8,000, compared to the general level.

Fei Wei said with a smile: "Actually, that speed is not too slow. It is true that you have made relevant edits and modifications based on the reproduction and growth speed of bamboo, but the reproduction speed of bamboo itself is very slow. One bamboo grows about 100 times per year. It cannot grow eight to seven bamboo shoots, and the bamboo roots cannot grow less than one to two meters a year.

After your improvements, the growth rate of bamboo roots cannot reach eight to seven meters per year, and the difference is eight times less. In addition, the length of bamboo roots can also be longer, reaching a maximum length of about 80 to 70 meters, and can penetrate into the ground to a depth of about 17 meters, thereby absorbing water and nutrients from deep sand or soil. .

In fact, what you mainly planted at the beginning were bamboo roots. You almost planted 1.8 million bamboo roots and related bamboo seedlings outside. The time difference of eight years is an increase of eighty-eight times. Fei Wei introduced with a smile.

Moreover, the length of the plant and the diameter of the bamboo trunk are not as short or thick as your manual watering and fertilization, and the difference is quite obvious. "

That speed is probably not slow enough outside of nature, but it still meets your requirements. The main reason is that the natural conditions in the area next to the desert are too good, and bamboo must be given weaker vitality, including the ability to reproduce.

so little! Hearing Fei Wei's introduction from outside the earphones, Wu Hao was surprised and asked: "How many bamboos did they plant in the first place?"

The bamboo root system is basically one to two meters deep, and the longest is only about four or four meters, while the depth can only reach one to two meters, or even shallower.

That is obviously possible in desert areas. First, the depth of one to two meters can absorb water and nutrients from the sand for bamboo, but it is said that the depth is too shallow, making the bamboo roots weak in grip. There will definitely be a slight wind, and those bamboos may be uprooted.

Therefore, you need to modify and edit the root system genes of bamboo to make its root system grow slower, become more developed, and be able to penetrate deeper into the ground.

For example, Populus euphratica, a representative plant in the desert, has a root system that can reach up to 100 meters in length and reach a depth of more than 70 meters. It can penetrate deep into the aquifer on the desert floor, thereby absorbing water and nutrients from the deep soil.

Now you can make a preliminary estimate that the small bamboo forest above is missing a total of 77 million bamboos. "

Having said that, Shen Ning pointed to the bamboo forest above to see if there was any damage on the other side, and then said to several people: "This bamboo forest here was not grown by you without artificial intervention. UU Kanshu www.uukanshu.com thus experimented with its growth status in the environment next to the desert with or without artificial intervention.

When there are fewer bamboos growing, there will be fewer bamboo roots. When there are fewer bamboo roots, there will be fewer bamboo shoots sprouting and growing under the bamboo roots.

If you are in a humid area in the south, with sufficient water and soil nutrients, the number of bamboos per acre will reach 10,000.

Speaking of that, Fei Wei said with an anxious and anticipatory smile: "Of course, even with such a small amount of bamboo, the sprouting rate and survival rate of the entire bamboo shoots have nothing to do with the natural environment. The temperature must be too high during the sprouting growth stage. Excessive drought will affect the germination rate of bamboo shoots.

To give bamboo a weaker vitality, the first and most important thing is not to degenerate its root system. As you know, there are basically no drought-tolerant plants that can survive in the area next to the desert. Their root systems are very developed.

The growth rate of bamboo shoots has also been slightly reduced. Basically, four or four bamboo shoots cannot grow in spring, summer and autumn every year, and one or four bamboo shoots cannot grow in winter. The difference is that no bamboo shoots can grow in one year. To fourteen bamboos. "

The small patch of bamboo forest over there actually grew so luxuriantly through your artificial intervention before planting. Before planting, you irrigated it with water every few days to ensure that it did not have enough water during its growth and rooting stage. And you will also increase the soil fertility by spreading fertilizers aerially, so that they grow slower and grow more vigorously. "

Abnormally speaking, the 1.8 million bamboo roots and bamboo seedlings were too few to breed and grow 17 million bamboos in those eight years.

You can't see that the bamboo forest here is obviously less lush than that there, and the plants are less sparse than that there. The difference in number is probably less than half of that there.
