The technology of "grafting" does not belong to Todd's major, but is a skill he mastered in the elective course he chose in his previous life at the university. When he chose that course, it was naturally not for learning, but for the sake of learning.
A beautiful female teacher who took elective courses. Unexpectedly, when traveling to another world, this skill would come in handy.
When all the materials are ready and before officially starting "rose grafting", Todd first needs to do some preparation work.
The first is disinfection. Use 75% alcohol to disinfect the knife and palms, and use formaldehyde solution to disinfect the wooden clamps and binding wires in a ventilated place.
The second is to choose the "scion". Try to choose rose branches and buds that are free from pests and diseases, no root nodules, and are one year old or less than one year old.
The third is to process the rootstock. Cut off the branches, leaves and the upper part of the stem of the wild rose, leaving the roots and the lower part of the stem, and the cut should be a smooth cross-section.
Next comes the formal grafting work.
Todd first used a knife to make a crosswise cut on the rootstock 6 cm from the soil, about 8 mm wide, with a depth that just penetrated the bark and reached the trunk; then he made a vertical cut under the middle of the cross cut, about 2 cm long.
A T-shaped incision was left on the bark of the rose tree.
Then select a suitable ear strip among the rose flowers, remove the leaves and leave the petiole, select a plump bud, and use a knife to cut an incision diagonally on the branch.
Finally, use a knife to open the cortex of the T-shaped incision of the rootstock, and carefully insert the rose buds into the incision. Immediately after placing it, fix it with wooden clamps and tie it with a rope.
Repeat the above process. Depending on the viability and vitality of the rootstock, up to ten rose scions can be inserted. You can choose more colors and styles of roses to enhance their beauty and shape.
The rose grafting has progressed to this point, which is half the success. Todd kept introducing the points to pay attention to in each step to the farmers around him.
Next, it’s your turn to cultivate and maintain the grafted product.
The first is temperature and sunshine. The temperature should be maintained in a relatively stable range, preferably between 22 degrees and 30 degrees. It is best to ensure sunshine for more than half a day every day. Therefore, Todd told the farmers to graft at night.
The roses are placed in a warehouse with a fire pit raised, and then moved outdoors when the sun is shining during the day.
Next is 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 fertilizing, it should be done every ten days. The fertilizer is a little broad bean shell, bean cake or chicken and pigeon manure.
etc., they enable the rose to continuously absorb various nutrients such as nitrogen, phosphorus and potassium from the soil.
Finally, there is a very crucial tip: preservative. Use a low-concentration mixture of silver thiosulfate and aluminum sulfate and pour it into the soil to extend the flowering period of roses and increase the brightness and tenderness of the flowers.
To sum up, the success of "rose grafting" mainly depends on the following 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
If it is not in place, it may cause the entire grafting work to completely fail.
Todd only stayed in the large warehouse for two days. He taught the farmers all the processes and steps of grafting, but he did not give the formulas for disinfectants, fertilizers, and preservatives. He only kept enough finished products.
, claiming that these are blessings from Heavenly Father.
He left all the remaining work to the farmers and ordered the guards in Muxi Town to guard the warehouse 24 hours a day and not allow anyone to approach. Todd couldn't wait to return to the laboratory because he had more important things to do on his hands.
.
Huggins told him that the petri dish of "Sutherland Archaea" was completed.
Artificial propagation of "Sutherland Archaea" was related to his life and fortune, so he couldn't let anything go wrong. Naturally, other things could be put on the back burner.
Walking into the door of the laboratory, Todd finally saw the petri dish he had been longing for. Rather than saying it was a petri dish, it might be more accurate to call it a "culture furnace".
It is shaped like a cylinder, made of copper alloy, and is about one meter high. The internal structure is divided into four layers. The top layer is a gas pipe, with air in and air out at the same time. There is a gas valve on both sides to control the flow and pressure; the second layer
It is a liquid tube that can inject solvent downward and divert the solution;
The third floor is the culture room, which is used to place samples or materials that need to be cultured and reacted. Two layers of small glass are specially installed here so that Todd can use "Perspective" and "Eagle Eye" to view the internal status; the bottom floor is
The fuel tank is used to add flammable materials such as charcoal to heat the entire tank.
It has to be said that the craftsman Huggins found has never disappointed anyone since refining silver. His craftsmanship in making instruments is really amazing. For this kind of large-scale experimental equipment, sealing, diversion, and thermal energy must be taken into consideration.
and corrosion and other factors. Originally Todd did not have high expectations for the finished product of the craftsmen, and planned to complete and improve it on this basis. Now it seems that there is no need for that at all. This "culture furnace" is completely
Can be put into use immediately.
But before the artificial culture of "Sutherland Archaea" can be officially started, sufficient samples must be extracted from the body first.
Todd changed the original syringe into a blood drawer, then purified the drawn blood, removed impurities, concentrated and distilled it, and obtained a little bit of embers similar to ashes.
Then put the ash powder into the "cultivation furnace", add charcoal and start heating slowly.
According to the records in the "History of Sutherland", the archaea should have been discovered in the crater, so several environmental factors may be the key to the reproduction of Sutherland's archaea.
Temperature, oxygen and acids and bases.
It's like a key with three teeth. Only by adjusting the shape and size of each tooth can it fit perfectly into the slot and open the door lock.
Based on the volcanic environment, we can only roughly speculate that the breeding environment of "Sutherland Archaea" is anaerobic and acidic with a temperature higher than 100 degrees Celsius.
What Todd needs to do now is to determine what degree the temperature needs to be, the degree of anaerobic (microaerophilic, facultative anaerobic or anaerobic), and what the acidic pH value needs to be.
This determination process is long and boring, requiring repeated experiments and observations, and recording and comparing experimental data. 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 was carried out, the "Sutherland Archaea" in the culture chamber resembled snowballs, condensing into small balls and slowly growing at high temperatures.
Turn and roll bigger and bigger.
Todd wiped his red eyes and pressed his face against the glass of the observation hole, with only one thought in his mind.
Artificial propagation of "Sutherland Archaea" was successful!
