Although Zhang Chun has been trying to influence researchers to use radical methods to breed species, as humans learn more and more about the natural world, the need for species selection is inevitable. Whether it is the maintenance of forest evolution and regeneration of forests, or the selection of planting and breeding species, there is no doubt that they have exerted influence. It's just that the effect is more moderate.

For example, for the chestnut trees in the forest, either the fruit is huge, or the taste is luscious, or it has rich nutritional value and medicinal value, or it is resistant to insects, or the chestnut tree has some special morphology preserved.

Other chestnut trees, which were deemed useless, were among those that were eliminated. Of course, if these varieties that are considered inferior are old enough, they will also be preserved, because this is beyond their value as a mere cash crop.

"A big tree is actually the support of a regional flora and fauna system, and there are hundreds of species of plants such as climbing, mosses, ferns, etc., and there are even more under the tree. It bears small fruits and has a bitter taste, but they are very numerous, and the fruits ripen just in time for other tree species, and feed many animals. So we found that there were some problems with the bias in thinning before, and now we are making some adjustments. There will be more or less some of the area in it. ”

"It's a balance that this species is kept as food for forest animals, and we have increased the collection of some of our favorite foods. If you spend a long time in the forest, you will find that your previous understanding is actually shallow and paranoid. ”

Two rangers looked up at a group of monkeys perched on the book.

Niuniu followed closely between Zhang Chun and Lizhi, her eyes scanning around vigilantly.

An hour ago. Niuniu met a wolf who was not afraid of her and wanted to eat her, and when she almost bit her, she was dragged back by the rangers.

Zhang Chun and Lizhi also laughed at her with tears in her eyes for a long time. Now Niu Niu knows that the animals in the forest are not as docile as the animals that people do. honestly put on the protective gear specially made for her. One hand was still tightly holding the corner of Lizi's clothes.

As soon as there was a stir, it hung on Zhang Chun and Lizhi's legs. But most wild animals are still afraid of her. Because she has a very complex fragrance on her body, some of which are the scent of fierce beasts. Niuniu already knows how to look at the eyes of animals to judge which animals can be bullied, and which animals should seek the protection of her parents.

This brought a lot of fun to Zhang Chun and Lizhi's travel.

Niu Niu has always wanted to catch a pet, but she is obviously a guy who likes the new and hates the old, and the cubs of an animal will be released in a few days.

Tao Nan already knew that Zhang Chun had fed two horses before, but later returned them to the military horse farm. also laughed at her for being the same as her parents. There is no qualitative possession of pets.

Tao Nan and Rong Yuehua's marriage was done a month ago, and the scene was very low-key. However, Pu Jie and Guo Buluo. Both Runqi and his wife attended the wedding. Many of the Manchu nobles stayed on the mainland, and Pu Jie and his wife presided over the work of the Palace Museum in Beiping. Wanrong's younger brother Runqi is studying in medical school, and Runqi's wife is Pu Jie and Pu Yi's sister Yun Ying. Both had studied in Japan before. Pu Yi announced his divorce from Wanrong and removed the identity of Queen Wanrong, and it was Pu Jie and Runqi, the younger brothers, who supported Wanrong.

Rong Yuehua can now keep up with Zhang Chun and his entourage, but most of the time it is Zhang Chun and his wife who protect Tao Nan and his wife. And not the other way around.

Tao Jing has been taken away by Dark Moon. The one who came to pick up Tao Jing was Shui Ling, who had become a beautiful girl. This girl is a year older and has changed a lot. Shui Ling hasn't seen her for two years. was laughed at by Zhang Chun, saying that she had changed from a doll to a disaster.

Because of her good talent and hard work, Shui Ling became a new generation of little princesses in the dark moon. Tao Jing was very unconvinced, but there was no way, the talent was not enough, and it was almost impossible to reach the level of Shui Ling. Tao Jing entered the special task team led by Liu Hui, and it took countless efforts and sweat to meet the requirements. Shui Ling went in and walked around for a few days. And then it came out, and it was very relaxed.

But when Shui Ling saw Niuniu. lamented that the future princess was not her, but this little kid of a few years old.

Niuniu already knew that Rong Yuehua, who looked heroic and sassy behind her, was actually an embroidered pillow, so as soon as she went out, she abandoned Aunt Rong who loved her very unjustly.

After Tao Jing left, Rong Yuehua's love turned to her.

The original seed farm is a flat land in the mountains, and it is the old terraced fields of the past, which have been preserved.

A road runs through the mountainside, which is the end of the transportation system. The roads are not wide, and cars can travel in both directions. But there are basically no cars. Workers in the original seed farm are accustomed to using horses or oxen to carry them to the pasture. Because it's not far from a freight terminal or a processing plant.

Out of the forest, Niuniu is happy, this is the age of chasing cats and teasing dogs. Frightened, the cats, dogs, wolves, cows and horses in the farmer ran around, and soon they came to play with the children. Rong Yuehua followed her.

This seed farm is still dominated by rice.

"In the past, the rice in the rice garden was fragrant and the rice grains were big. It's hard to grow in other places. However, it has now been discovered that as long as the fertility of the land reaches a certain level in each place, the rice grown will have unique characteristics. This land is moon-grade, you can see that the soil is black, there are many microbial populations, and the microbial populations of the surrounding environment are also very distinctive. Originally, this rice was just a wild rice seed of millet grains, which was left to ensure the original seed. However, after several generations of breeding, although the rice produced by this rice variety is still small, it is resistant to shade, water and fertilizer, diseases and pests, lodging, and suitable for dense planting. Although the yield is at the middle and lower level, it is very sticky rice, and the rice is soft and sweet. The disadvantage is that it is not possible to plant fields below the moon level. ”

This rice is still in the form of wild rice. The leaves are slender and the plant is not tall, but the ears are neat. The biggest feature of this rice is that it grows well in the shady areas of the rice fields in the forest, and the growth period is longer than that of ordinary rice. It can only be ripened once a year.

Lizhi and Zhang Chun's family like to eat this kind of rice, not only because of the taste, but also because the nutrition is obviously higher than that of ordinary rice, and there are far fewer impurities that are not suitable for digestion.

If evaluated in terms of nutritional value, the yield of this rice is not low at all. It is even able to reach a medium to high level. Don't look at some varieties with high yields, but Zhang Chun doesn't like them because their digestion and utilization rate is too low.

"What is the standard for month-level farmland?"

"This, in general, has an active humus layer of 80 centimeters, water and fertilizer condense in the soil, and there are some microbial indicators. Not every variety of crops can be grown in month-level farmland. Some varieties grow leaves in moon-level farmland, and the plants grow quickly, but the fruiting rate is very low. Therefore, unless there is a special purpose, the farmland will be maintained at the standard of two to three stars. ”

"You're going to control soil evolution?"

"Yes, there needs to be a balance between yield and quality, for example, rice of this quality is too demanding, and the yield is not high, if it were not for the research and protection of the species, we would give up planting. Of course, last year my husband ordered this kind of rice, and we expanded some of the planting area. ”

Zhang Chun and Lizhi walked on this farm, speaking of which, Zhang Chun and Lizhi's life is considered luxurious, because at least three farms and original seed farms around them are planted with the food that their family likes to eat, almost all of them are month-level farmland, and the forest vegetation is also rated as month-level.

Mr. and Mrs. Zhang Chun often participate in forest management activities here. So some plants that Zhang Chun thought had too many impurities were eliminated. It became the nutrient of the forest soil. In order to pursue high nutrition, Zhang Chun and his wife allowed some poisonous plants to exist, but some high-yielding varieties are difficult to find here.

The farm unconsciously satisfies its needs because of the food that Zhang Chun likes to eat, and of course they eat it themselves.

In addition, most of the people here are people sent by Dark Moon to protect Zhang Chun, no matter what kind of industry they are engaged in, almost all of the people around the fairy are from Dark Moon now. The people of the Darkmoon are also picky about their food. It's just that it's not as strict as Zhang Chun and Liqian.

Children born here are generally in better physical fitness than other places, not to mention that they have been trained by adults with drugs and kneading techniques from an early age. The forests and their domesticated livestock and pets are also wilder and more spiritual than outside, and competition and fighting between species can be seen everywhere. People are used to it.

It is also very dangerous for the three-star rangers to enter this area. Because this is an ordinary snake, it is also more poisonous than the outside.

This is the reason why Tao Nan and Rong Yuehua still need the protection of Zhang Chun and his wife. (To be continued......)
