After lunch, Wen Yanran quickly drove away, and her parents and second sister also went to work in the greenhouse. This season's vegetables have begun to be produced, and there is a lot of work in the greenhouse.

Kang Mingsong returned to the room and thought about the problem of planting precious and rare ingredients just raised by Wen Yanran.

For these precious and rare ingredients, Kang Mingsong doesn't know much, and basically stays at the level of knowing the name. In the past, the family's economic situation was not good, and their family was almost insulated from these expensive and rare ingredients, that is, morels, bamboo sunflower and gastrodia and other wild ones around the house, so they still knew about these kinds, but there were no wild species, so they really only heard of their names.

But it doesn't matter if you don't understand, who calls it the Internet era, there is an omniscient Du Niang, and no matter how far away the knowledge is, you can also learn about it.

Kang Mingsong learned that whether it is bamboo sunflower or morel, at this stage has actually been artificially planted, as for gastrodia, this does not need to check the information on the Internet, Kang Mingsong also knows that it can be planted artificially, because there are local people in the mountain village who are planting gastrodia.

But unfortunately, Kang Mingsong himself does not have the conditions to grow gastrodia artificially.

Generally speaking, Gastrodia has a wide range of living environments, and almost half of China can see its traces in the north and south of the Great River, inside and outside the Great Wall. From the hills at an altitude of 400 meters to the mountains at an altitude of 3,200 meters, under the sparse forests, the glades in the forests, the edge of the forest, and the edges of the bushes, are all places where they live.

However, I don't know if it is a special attribute formed by a specific environment, but in the mountain township, the distribution of gastrodia is very strange, and it can only survive on Qianhui Mountain above 1,300 meters above sea level, and it will die once transplanted below.

Therefore, for many years, only seven groups of residents in the backing community, which were originally located at a high altitude on the Qianhui Mountain, have had experience in growing gastrodia.

However, in recent years, the residents of the seven groups of the mountain community have been relocated to a new community on the edge of the market town because of the reasons of returning farmland to forest and alpine ecological poverty alleviation.

After all, such a precious Chinese medicinal material, even if it is planted, is very valuable. If there is no one to guard at all times, someone may steal it.

In fact, the gastrodia grown in the high-altitude area of Qianhui Mountain is not much different from the wild gastrodia, because these gastrodia in the backing mountain township, in addition to the unexpected requirements for the altitude of growth, there is also a quirk, that is, there is no chemical fertilizer at all, otherwise there will definitely be rotten roots.

With these special restrictions, it is difficult for Kang Mingsong to engage in gastrodia cultivation on a large scale, because after the residents of the seven groups moved to the edge of the market town, the original place has been brought under the management of state-owned forest farms.

As the high-voltage lines for environmental protection are tightened, it has become very difficult to obtain the development rights of state-owned forest farms.

………………

It is unlikely that large-scale cultivation of gastrodia will be made, but it is not difficult for morel mushrooms and bamboo sunflowers, which are among the "eight treasures of grass", to grow on a larger scale.

Morel mushrooms are distributed in mixed coniferous and broad-leaved forests, mostly growing on broad-leaved woodlands and roadsides, while there are few other mountain communities that are mountainous forests.

Seventy percent of the 20 square kilometers of the village are mountain forests, with a total area of more than 20,000 acres. Even if we exclude nearly 8 square kilometers of forest areas under the management of state-owned forest farms, there are still nearly 10,000 acres of forest land.

These places are potential sites for morel mushrooms.

Nowadays, morel mushrooms can be grown in greenhouses, so greenhouses can also be built in cultivated land to grow morels.

As for the bamboo sunflower, it is also distributed in the backing mountain communities. Although there are not as many bamboo forests in the backing communities as there are mountain forests, the whole village combined, Kang Mingsong is estimated to be no less than 500 acres. More than seventy percent of these bamboo forests are bamboo, followed by bamboos and wattle, and these kinds of bamboo woodlands are the main environment for the natural growth of bamboo.

In fact, local residents often find the existence of bamboo sunflower in their own bamboo forests, but they are relatively scattered and do not produce much.

The technical difficulty of planting bamboo sunflower is not high, and there is no one to grow bamboo sunflower in the Guxing area, and there are resource advantages such as land and bamboo, which makes Kang Mingsong a little tempted.

However, he also has concerns, that is, the annual yield of bamboo sunflower is very small, firstly, because the land cannot be replanted, and secondly, the conditions of raw materials such as bamboo chips must be limited.

………………

In addition to these rare and precious ingredients that are very common in the local area, Kang Mingsong also inquired about some other precious ingredients that may be planted on a large scale in the local area, such as lion's mane mushroom, white fungus and daylily, which are also listed as "grass eight treasures", and matsutake mushrooms, truffles, etc., all of which have the possibility of large-scale cultivation in the backing mountain township.

Among them, daylily is also planted by locals, Kang Mingsong has been planting it at home for decades, but it is planted on his own ridge, and the yield is not much, and he can only harvest ten catties of dried daylily a year.

In addition, lion's mane mushroom and white fungus, as well as matsutake mushrooms and truffles, although they are not found locally, but after Kang Mingsong looked at their growing environment, he knew very well that the mountain township was suitable for the growth of these precious and rare ingredients.

It's just that these precious and rare ingredients, although they have been initially planted artificially, but compared with ordinary vegetables, their growth still depends on the season, and they are only one season a year, and they cannot be planted out of season.

The constraints of these conditions, coupled with the relatively low production per unit area, have greatly affected its value.

Don't look at these precious and rare ingredients are often hundreds or even thousands of pounds, the price is completely incomparable with ordinary vegetables, but considering the difference in output between each other, their output value per unit area is actually not comparable to ordinary vegetables, especially ordinary vegetables after being cultivated by super breeders.

Tomatoes, for example, can be grown at least twice a year because they can be cultivated out of season. Considering that its yield can reach a terrifying 10,000 catties, it can produce 20,000 catties per mu in a year.

According to the price of four yuan per catty sold by Kang Mingsong to Wen Yanran, the output value of this mu of land can almost reach more than 80,000 yuan a year.

If you replace it with precious strains such as morel mushrooms and bamboo sunflowers, even if its unit price is as high as hundreds of yuan or even thousands of yuan a catty, it is not easy to achieve the annual output value per unit area of ordinary vegetables such as tomatoes.

Of course, the bigger problem comes from the seeds, most of which are mushrooms, which are spore organisms that are difficult to collect. Even if they are available on the market, it is still unknown whether the super breeder can be bred.
