Four Hundred and Twenty Seventh Insect Tree Research
The National Biological Laboratory in Beidu planted more than a dozen insect trees in a fully enclosed laboratory by taking advantage of the plundering properties of insect trees. The competition between the insect trees was extremely fierce. The planting distance of the two insect trees was too close. The tentacles on the ground actually collided, entangled and tore each other, and finally one side lost and fell down as a result.
But in two days, half of the twelve insect trees died, and two more died on the third day.
The experimental group headed by Professor Qin thought that the remaining four insect trees would continue to compete, but after a few days of observation, they found that the competition among the insect trees had stopped!
The experimental group immediately adjusted the experimental method and transplanted four insect trees together. The distance was close enough for the insect trees to "fight", but the four insect trees remained peaceful.
The experimental group immediately arranged several other groups of control experiments, and found that after a period of competition, each group of experimental insect trees would automatically stop the competition when there were three or four remaining. The insect trees in the same group were transplanted together without any abnormality.
The reason is not difficult to guess - the worm tree has already accumulated enough nutrients, and there is no need to devour the same kind to plunder nutrients!
The experiment did not end here, but continued to be carried out in depth, and tortured the worm tree by reducing water, increasing water, strengthening light, keeping dark, etc., in order to observe the situation of the worm tree.
It was found that insect trees that have accumulated enough nutrients hardly need to absorb nutrients from the outside, and light has no effect on the insect trees, but if the insect trees do not get enough water, the number of insect eggs in the canopy will decrease by 20% to forty.
This is good news, but a single insect tree can produce more than a thousand insect eggs at most, even if the output is reduced by half, there are still five or six hundred eggs.
Unless there is a large-scale drought, the possibility of water shortage in the natural environment is extremely small, so such research results are dispensable at all, and they are of no help to the situation facing human beings.
Of course, the experiment is not over yet. The laboratory began to torture insect trees with various methods, including but not limited to digging roots, cutting roots, destroying the crown, cutting off the fleshy trunk from small to large, peeling off the epidermis in various areas, and various animal and plant virus infections. , exposure to various chemical substances, etc.
In short, the laboratory used all the methods imaginable on the worm tree, just to find a solution that could effectively kill the worm tree.
It was found that destroying the insect tree by physical means can only reduce the production of insect eggs. As long as the insect tree absorbs enough nutrients, even if the crown of the tree is picked off alone, a certain amount of insect eggs can be produced.
Only by destroying the canopy can a large number of immature eggs be necrotic, but it must be destroyed when the eggs are immature to be effective.
If the eggs are close to maturity, the development of many eggs can only be terminated by completely destroying the canopy, otherwise some eggs will survive more or less.
The virus infection experiment has almost no effect. The virus from the earth is either unable to infect, or cannot invade the crown of the tree after infection, and there is no possibility of the virus killing insect trees in the short term.
The exposure experiments of chemical substances are similar. Chemical substances with weak toxicity will not work on insect trees. Chemical substances that work are too toxic. If they are used on a large scale in various countries, even if the insect trees are not extinct, more than half of human beings will die first. .
In order to find out where the limit of the worm tree is, the laboratory even took out the big killer of radiation, irradiated the worm tree with rays of different levels, and observed the changes of the worm tree in the radiation.
The result is gratifying. After several days of continuous irradiation, the insect tree quickly withered and died, but the crown was still completely intact, but the tentacles on it all shrank.
The insect eggs in the canopy are still active, and even if they are exposed to extremely strong radiation for a long time, they will not hurt the eggs.
This is not surprising at all, the radiation intensity in the universe is very high - the height of the space station is between 300 and 400 kilometers, this position belongs to the low earth orbit, within the protection range of the earth's magnetic field, the radiation intensity is not high .
But that's not the case outside the Earth's magnetic field.
The asteroid has been flying in the starry sky for several months, and the radiation intensity it receives is quite high. If the shell of the white egg has no radiation protection ability, how can it take root and germinate after it falls on the earth?
The researchers immediately became very interested in egg shells. Through experiments, they found that the anti-radiation ability of egg shells is far beyond human imagination. Even if they are thrown into a nuclear reactor, there will be no radiation inside the egg shells... Of course, this stuff It can only block radiation but not high temperature. If it is really thrown into the reactor, it will be turned into ashes by the high temperature in minutes.
Egg shells are just an unexpected harvest in the research of worm trees, and the research on worm trees is still going on.
After trying all the means, they still couldn't find an effective method to deal with the worm tree. The laboratory had to change its thinking, no longer deal with the worm tree, but started with the eggs cultivated by the worm tree.
The insect eggs that have just escaped from the insect tree are larger than ordinary insect eggs, but the hatching of these eggs does not require any specific environment, and the hatching speed is not slow, it takes about seven to ten days, and the length of time depends on the outside world Depending on the environment, even a high temperature and arid desert will not affect the hatching of eggs.
Fortunately, the newly hatched larvae are very fragile. Various insecticides can effectively kill the larvae at this stage, but as long as you wait for a few hours, the effect of the insecticide will be greatly reduced after the larvae's shell hardens. Only highly poisonous potions can play a certain role.
In order to determine the anti-virus ability of the larvae, the laboratory even used nerve gas. Although the effect is very good, the toxicity of this thing is too high, and no one dares to use it indiscriminately on their own land.
The larvae are almost as big as the belly of a finger, but don't underestimate these little things. They have strong appetite and aggressiveness. Once they successfully hatch, they will immediately sweep the surrounding area and eat all the animals they can find.
The worm tree plunders the nutrients of the plants, and the larvae eat up the nearby animals. The domineering of this thing can be seen.
If they can't find enough food, these little guys will even kill each other, devouring their brothers and sisters who were born together one by one, and the last remaining one or a few are the fiercest and most powerful individuals.
At this time, the giant biochemical worm can grow to around thirty, and initially has the ability to travel far.
Due to the limited size, firearms can easily deal with larvae at this stage, but if the larvae can continue to grow and reach a length of over one meter, it will be difficult for ordinary firearms to penetrate the shell of the biochemical giant worm.
So far, the laboratory's research on biochemical giant insects has come to an abrupt end. It's not that the laboratory doesn't want to continue researching, but that the biochemical giant insects have already possessed extremely strong attack power. The closed experimental cabin of the laboratory can't stop the destruction of biochemical giant insects. . (To be continued.)
