The next day was May 2nd, which was already the last day of the May Day holiday.

After having breakfast at Kang Mingsong's house, Yuan Bingya and Yuan Tianchu drove back to the city. Yuan Tianchu had to take the afternoon bus back to the university campus in the city, he was only in his third year, and it was the time when he was nervous about studying.

Yuan Bingya didn't have to rush back to school immediately, because her affairs at the university had already been dealt with, and she only needed to wait until the end of June to go to the school to collect her graduation certificate and degree certificate.

Regarding the arrangement of this time, Yuan Bingya said that she is ready to find an internship in a unit, and while waiting for the interview session of the civil service examination in early June, it can be regarded as accumulating work experience for her upcoming career.

Kang Mingsong is also not idle, it is already May, and the first season of vegetables in the planting base is about to enter the peak season, although the sale of these vegetables does not require him to bother, but it does not mean that he can be easy, because he has to prepare for the next season of vegetable planting.

There are a lot of seedlings needed for the production base of more than 60 acres.

From mid to late March, after the first season of seeds needed for the planting base is enough, he has accumulated all the seeds cultivated by the super breeder, and now it is time to think about breeding.

After all, there is a little more than a month to go, and the first season of vegetables planted in the planting base will pass the peak production period one after another, and the plants need to be pulled out and replanted with new seedlings.

That is to say, at the latest in early July, the second season of vegetables in the planting base needs to be transplanted.

………………

However, before cultivating seedlings for the planting base, Kang Mingsong still has one more thing to complete, that is, to cultivate seedlings for the five acres of land at home.

Compared with the vegetables in the planting base that have just entered the output period, the vegetables planted in the five-acre greenhouse in Kang Mingsong's house are two months earlier, and now they have passed the peak production period and have really entered the decline period.

Originally, Kang Mingsong should have cultivated seedlings for his family's five acres of land, but he deliberately dragged it down. It's not that Cummingsong wants to pit himself, but he has a better choice.

After planting two seasons of greenhouse vegetables and one season of seasonal vegetables, the economic value created by the seeds cultivated by the super breeder will finally exceed 1.11 million, and the experience value accumulated by Kang Mingsong is about to reach 100, and the super breeder can be upgraded for the third time.

The upgraded super breeder will not only enhance the breeding ability again, but also increase the attributes that can be cultivated by each variety.

Cultivating more special attributes is obviously beneficial for the product.

………………

On May 4th, Kang Mingsong finally reached 100 experience points, and he did not hesitate to upgrade the super breeder.

Soon, Kang Mingsong was prompted that the cultivation capacity of the super breeder reached 1,000 grams each time, and the special attributes that a single variety could breed also reached four.

However, in this upgrade, the cultivation interval has not been shortened, and it is still maintained at three days.

In addition, after this upgrade, the cultivation privilege of the Super Breeder unlocks the cultivation of fungal species. In other words, Kang Mingsong can cultivate the morel mushrooms and bamboo sunflower strains that he has cultivated in private.

However, Kang Mingsong has no such plan for the time being, firstly, it is still early before the season to plant morel mushrooms and bamboo sunflower, and secondly, the current cultivation capacity of the super breeder is still not enough for the cultivation of these two rare strains.

After all, the current super breeder does not have the extraction function, and there is no way to extract morel mushrooms and bamboo sunflower strains. If you want to cultivate these two rare strains, you can only cultivate fungus soil.

With the current cultivation capacity of the super breeder, it is only ten kilograms of fungus soil in a month, what can this do?

What's more, Cummingpine still needs to be cultivated in other varieties.

What Kang Mingsong hopes most now is that when it comes to the planting season of these two precious and rare strains, the seeds cultivated by the super breeder have brought economic benefits that have exceeded 10 million levels, and the super breeder has been upgraded to the fourth level.

At that time, the weight of seeds grown in the Super Breeder was 10 kg at a time, and the incubation interval would be significantly reduced again to once a day.

At that time, the cultivation capacity of the super breeder will be greatly increased to 300 kg per month, which is a real qualitative leap in breeding capacity.

………………

Because a large number of tomatoes, peppers and cucumbers are planted in the planting base, after the super breeder upgrade, Kang Mingsong decided that these three vegetables will no longer be grown in his greenhouse, and he will change to a new product.

In fact, it can't be regarded as a new product, because the product he plans to grow is actually already planted in the planting base, that is, watermelon.

Watermelon can be called the "king of midsummer", refreshing and thirst-quenching, sweet and juicy, and is a good fruit in midsummer.

In addition to not containing fat and cholesterol, watermelon contains a lot of glucose, malic acid, fructose, protein amino acids, lycacein and rich vitamin C and other substances, which is a highly nutritious, pure and safe food.

The flesh of watermelon generally contains 5-12% sugar, including glucose, fructose and sucrose. The sweetness increases with the increase of sucrose in the late maturation period.

Watermelon is not only a good taste, but also plays an important role in dietary therapy and health care, and is used in ancient and modern times for folk healing and dietary health care.

"Benjing Fengyuan" records: watermelon can attract the heat of the pericardium and diarrhea from the small intestine and bladder. It can quench the sun, yang and fever and thirst, so it is called the natural "white tiger soup", the white tiger soup is the Han typhoid fever prescription, the function is to clear heat and generate Jin, quench thirst and remove annoyance, that is, the watermelon skin and its same work metaphor. In spring and summer, there is a distemper, and collectors are found to eat it in the next year, such as Tang Woxue.

"Records of the Pine Desert" cloud: Some people suffer from eye diseases, so they make watermelon slices exposed to drying, take them every day, and then heal, and reduce fire from their coldness.

"Suixingju Diet Recipe" cloud: Those who eat melons and have bloating can be eliminated by drinking winter pickled vegetables and soup. Dried and pickled with watermelon flesh; sores in the lips are burned with watermelon skin; too many melons are eaten to relieve the disease; stomatitis is dried with watermelon skin, fried and scorched, a little ice chips are added to the ground with the same grinding, and the affected area is coated with honey.

Pregnant women often eat some watermelon during pregnancy, which can not only supplement the nutritional consumption in the body, but also make the fetus's nutritional intake better satisfied.

Eating some watermelon in the first trimester of pregnancy can quench thirst, remove greasy and annoyance, and also have a good effect on antiemetic.

At the end of pregnancy, pregnant women often have different degrees of edema and increased blood pressure, often eat watermelon, not only can diuretic swelling, but also lower blood pressure, which is also beneficial to the health of pregnant women.

Watermelon can also increase the secretion of **, therefore, it is beneficial for pregnant women to eat some watermelon.

Eating some watermelon before and after childbirth can treat and correct anemia in pregnant women. For example, pregnant women who give birth in the middle of summer, often eating watermelon can prevent heatstroke and cool down, and eliminate the heat in summer. Watermelon contains sugar, which has the effect of replenishing energy and protecting the liver.

In the process of childbirth, many women have mental stress, prolonged labor, blood loss and sweating, fatigue, weakened gastrointestinal peristalsis, loss of appetite, constipation and other phenomena, at this time, eating some watermelon can not only replenish water, increase the intake of sugar, protein, inorganic salts, vitamins and other nutrients, stimulate intestinal peristalsis, promote smooth stool, but also increase the secretion of **, and help the wound healing of postoperative mothers.
