Alien Knights

The technique of "grafting" does not belong to Todd's major, but a skill he mastered in the elective courses he chose in his previous life university. At the beginning, he chose that course not for learning, but for the beautiful female teacher who took the elective course. Unexpectedly, after traveling to another world, this skill will come in handy.

When all the materials are ready, Todd needs to do some preparatory work before officially starting the "rose grafting".

One is disinfection. Use 75% alcohol to disinfect knives and palms, and use formaldehyde solution to disinfect wooden clips and binding wires in a ventilated place.

The second is to choose "scion", and try to choose rose buds without pests and diseases, no root nodules, one year or less than one year.

The third is to deal with the rootstock. Cut off the branches and leaves and the upper part of the stem of the wild rose, and keep the root and the lower part of the stem, and the cut is a smooth cross section.

The next step is the formal grafting work.

Todd first cuts the rootstock 6 cm away from the soil with a small knife, about 8 mm wide, and its depth just penetrates the bark and reaches the trunk; then cuts vertically under the middle of the cross cut, about 2 cm long. Make a T-shaped incision on the bark of the briar.

Then select the appropriate spikes from the rose flowers, remove the leaves and leave the petioles, choose a full and plump bud, and use a knife to cut an incision obliquely on the branch.

Finally, use a knife to pierce the cortex of the T-shaped incision of the rootstock, and carefully insert the rose buds into the incision. Immediately after putting it in place, fix it with wooden clips and tie it up with a rope.

Repeat the above process, according to the survival and vitality of the rootstock, up to a dozen rose scions can be inserted. Roses can choose more colors and styles to enhance the beauty and shape.

Rose grafting has been carried out here, which means half of the success. Todd kept introducing the points of attention in each link to the farmers around him.

Next, it is the turn of how to cultivate and maintain the grafted products.

The first is temperature and sunlight. The temperature should be maintained in a relatively stable range, preferably between 22 degrees and 30 degrees. It is best to ensure more than half a day of sunshine every day. Therefore, Todd told the farmers to put the grafted roses in the warehouse with a fire pit at night, and move them outdoors during the day when the sun is shining.

Followed by pruning and fertilizing. During the growth process of roses, side branches, diseased branches and concentric branches must be cut off in time to prevent nutrient diversion. As for fertilization, once every ten days, the fertilizer is a little broad bean shell, bean cake or chicken and pigeon manure, etc., which can make the rose continuously absorb various nutrients such as nitrogen, phosphorus and potassium from the soil.

Finally, and a very crucial tip: preservatives. A mixture of low-concentration silver thiosulfate and aluminum sulfate is poured into the soil to prolong the flowering period of the rose and increase the freshness and tenderness of the flowers.

To sum up, the success of "Rosa Grafting" mainly has the following key points: disinfection, incision, scion, temperature, sunshine, pruning, fertilizer and preservation. The whole process seems simple, but as long as any link is wrong or not in place, it may cause the entire grafting work to fail completely.

Todd stayed in the big warehouse for only two days. He taught the farmers all the procedures and steps of grafting, but did not give out the formulas for disinfectant, fertilizer, and preservative. He only kept enough finished products, claiming that these are the blessings of the heavenly father.

Leave all the remaining work to the farmers, and order the guards in Muxi Town to guard the warehouse 24 hours a day, and no one is allowed to approach. Todd couldn't wait to return to the laboratory, because he had more important things to do at hand.

Huggins told him that the petri dish of "Sutherland Archaea" was finished.

The artificial propagation of "Sutherland Archaea" is related to his wealth and life, so he can't help but make any mistakes, and other things can naturally be put on the back burner.

Walking into the door of the laboratory, Todd finally saw the petri dish he had been thinking about day and night. Rather than calling it a Petri dish, it might be more accurate to call it a "Cultivation Furnace".

The shape of the cylinder, the material of copper alloy, is one meter high, and the internal structure is divided into four layers. The uppermost layer is the gas pipeline, which takes in air and leaves it at the same time, and there is a gas valve on each side to control the flow and pressure; the second layer is a liquid pipe, which can inject solvents downwards and divert the solution; the third layer is a culture room, which is used to place samples or materials that need to be cultivated and reacted. Two layers of small glass are specially installed here, so that Todd can use "see-through" and "Eagle Eye" to check the internal state; the bottom layer is a fuel tank, which is used to add charcoal and other flammable materials to heat the entire tank.

It has to be said that the craftsman Huggins found has never disappointed since the beginning of refining silver. The craftsmanship of artificially making utensils is really amazing. This kind of large-scale experimental equipment must take into account many factors such as sealing, flow diversion, heat energy and corrosion. Originally, Todd didn't have much expectation for the craftsman's finished product, and planned to complete and improve it on this basis. Now it seems that there is no need for that at all, and this "incubator" can be put into use immediately.

But before officially starting the artificial cultivation of "Sutherland Archaea", sufficient samples must be obtained from the body.

Todd changed the original syringe into a blood drawer, and then purified, removed impurities, concentrated and distilled the drawn blood, and obtained a little bit of ashes like ashes.

Then put these ashes into the "cultivation furnace", put in charcoal and start to heat slowly.

According to the records of "Sutherland History", the discovery of archaea should be in the crater, so several environmental factors may be the key to the reproduction of Sutherland archaea.

temperature, oxygen, and acids and bases.

It's like a key has three teeth. Only by adjusting the shape and size of each tooth can it be perfectly inserted into the hole and open the door lock.

According to the volcanic environment, it can only be roughly speculated that the breeding environment of "Sutherland archaea" is an anaerobic and slightly acidic environment with a temperature higher than 100 degrees Celsius.

What Todd needs to do now is to determine the temperature, the degree of anaerobic (microaerobic, facultative anaerobic or anaerobic), and the acidic pH value.

This determination process is long and boring, requiring repeated experiments and observations, as well as recording and comparing experimental data, and at the same time, every factor that may distort the experimental results must be taken into account.

Finally, on the morning of the nineteenth day after the experiment started. Fifteen minutes after Plan No. 183, the "Sutherland Archaea" in the culture chamber were like snowballs, condensed into small balls that slowly rotated in the high temperature, and rolled bigger and bigger.

Todd wiped his reddened eyes and pressed his face to the glass of the observation hole, with only one thought in his mind.

The artificial propagation of "Sutherland Archaea" was successful!

Well, I finished it before midnight...
