This kind of seed is about to be sown, so naturally there is no need to dry it anymore, Xu Yi just put them aside and sorted out a piece of land directly next to it to make a small seedbed.

Xu Yi encountered a little problem when sowing seeds, originally the seeds sown yesterday were dried in an afternoon and a night, although this kind of seeds are a little smaller, but no matter how you say this, this thing will not stick to your hands, and the amount of seeds is not very much, so he directly grabbed the seeds with his hands and sowed them little by little, so although the sowing is not very uniform in some places, it is rare for more than three plants to grow together.

But this method of sowing does not work today.

This amount of seeds is naturally much more than yesterday, and although there is no mucous membrane outside, the freshly washed seeds are so moist that they are easy to form a ball in addition to sticking to their hands, and it is difficult to operate the sowing method like yesterday.

Staring at the seeds and pondering for a while, Xu Yi went to find a plastic bag, found some loose broken soil, and filled it with almost half a bag. Then, Xu Yi directly poured all the seeds on the nylon net into the bag, mixed them evenly with the soil, and then grabbed the mixture in the bag and sprinkled it evenly on the seedbed, so that the seeds were sown evenly, and then covered the seedbed with a thin layer of dry soil, Xu Yi took the watering can and poured some water on them, and walked directly to the flower pots that had been received before.

If you sow these ice powder seeds, you will be able to transplant them tomorrow night, and when they are planted, you can water them directly.

The yield of ice powder seeds is not too low, if you transplant it. One or two thousand trees per acre of land would suffice, and all of these seeds would sprout. How can you plant ten acres and eight acres?

One acre of ice powder seeds can harvest at least three or four hundred catties of ice powder seeds, if you really plant them. How can you harvest three or four thousand catties of ice powder seeds, but I am afraid that no matter how good my business is, this summer will be enough.

Xu Yi ran back and forth a few times, and moved all the pots to the open space near the side of the pine and cork oaks, ready to transplant the mint in the pots to the ground.

Peppermint is a perennial herbaceous plant, and if you have enough seedlings, you can continue to harvest mint leaves as long as you plant enough area.

The mint in these pots is almost the same, and there are seven or eight mint plants in each pot. However, compared to the area you want to plant, even if you can't really transplant all of them into the ground, this is just a drop in the bucket, and it is far from your expected goal.

Xu Yi didn't think about simply planting them separately, in fact, he wanted to cut them down.

Peppermint is one of the commonly used traditional Chinese medicines, and it can be collected at home, so Xu Yi naturally knows more about this thing.

Just like after Xu Yi tasted those peppermints yesterday, the choice of peppermint was not purely from the perspective of taste.

What makes people feel "cool" in peppermint is a substance called menthol. Menthol is the main component of peppermint oil, accounting for more than 80% of peppermint extract. It is also one of the main components of peppermint in the application of traditional Chinese medicine.

Menthol is a volatile substance, and using toothpaste or gum that contains menthol can make you feel cool, but it's not because menthol evaporates and absorbs heat from your body.

In fact, human skin and mucous membranes have a "cryoreceptor" that is used to receive cold stimuli. Cold receptors are unevenly distributed on the body surface, and are more distributed on the trunk than on the limbs, so the body is more sensitive to the sensation of cold than the limbs. That's why it doesn't feel like anything to try cold water with your hands. That's why it takes a lot of courage to jump into a cold pool and take a cool shower.

Among the cold receptors, one of the receptors that receive cold stimulation is the calcium channel receptor. But this channel can be activated by low temperatures, changes in membrane potential, etc. When these receptors are activated, "cold" signals are transmitted through guò nerves to the temperature sensing centers of the cerebral cortex. That's when we felt the coolness. Next, the brain will send out various body instructions, such as shivering, inhibiting the secretion of sweat glands, and so on.

Menthol, on the other hand, causes people to feel cool, by directly activating the cold receptors in the area to produce a calcium ion influx signal similar to that under low temperature conditions, creating an illusion of coolness.

However, in this process, the temperature of the human body is not really lowered because of this coolness, but because of its effect, it interferes with the normal heat dissipation path and exacerbates the heat accumulation.

In addition, menthol has a certain inhibitory effect on the central nervous system, so if a large number of menthol products are used on the body surface, it is very likely to lead to temperature regulation disorders, and even cause the consequences of strict treatment.

Therefore, peppermint is not toxic, but menthol with too high a concentration has a certain toxicity, and adults may be fatal if they ingest more than two grams of menthol at a time.

The reason why Xu Yi bought this peppermint is not without reason, this kind of peppermint tastes good, and the taste of peppermint is not as pungent as ordinary mint, it is conceivable that the menthol it contains is less than the menthol content in the mint commonly used in traditional Chinese medicine. This thing is planted in the space, even if the menthol content in this mint increases, it will not reach the same level as ordinary mint.

The mint oil content contained in ordinary peppermint is about one percent, while the concentration of menthol contained in peppermint oil is about eighty percent. This also means that from a safety point of view, taking 100 grams of fresh mint this time is still above the safety line. Choosing this peppermint variety with lower menthol content undoubtedly makes mints safer to eat - after all, I just use them as seasonings, not as main ingredients.

The stem of mint is a semi-stolon, each section can give birth to lateral roots, plus he has the big killer of space water, it is not a problem to plant it at all, there is no doubt that this also makes Xu Yi very relieved.

Xu Yi used scissors to cut the mint out of the pot, directly cut the mint stem into sections, cut it into the ground, and after cutting all the aboveground parts, Xu Yi turned the pot upside down and planted the rhizomes inside separately.

Soon, all the mint in the pot was processed, and a small field of mint with a little greenery appeared on the ground.

Xu Yi directly poured space water on them with a watering can, and soon these mints quickly grew, and clusters of small lilac flowers bloomed on the tips of some of the newly issued stems, and the rich floral fragrance attracted a large number of bees. (To be continued......)

PS: There are still three thousand left, well, take your time, if you are not busy, tomorrow two more six thousand words will be over - but it may not be big, if you are busy, it will be like today, two more four thousand.
