It is a sterile line and a restorer line of rice seeds, and the students from the Agricultural College have greatly improved the efficiency of searching for rice seeds.

Now there is only one maintenance line of rice left for the three lines of rice, and as long as the students of the College of Agriculture find the last rice seed, the hybrid rice that Xu Yue has planned for several years will be realized.

However, Xu Yue couldn't wait any longer, and the change of the current situation made her eager to get hybrid rice seeds.

Xu Yue restrained her excitement and entered the research room with two rice seeds, trying to bargain with the tech tree to get the finished hybrid rice.

However, after waiting for a long time, the tech tree did not respond.

Xu Yue didn't want to give up like this, she wanted to plant hybrid rice that could change the fate of mankind when she ploughed next spring.

Seeing that there was no movement in the science and technology tree, Xu Yue looked at the two rice seeds in her hand, and after a period of brainstorming, she suddenly had an idea.

If she doesn't give the finished tech tree, then she just needs the remaining third rice seed?

Thinking of this, Xu Yue immediately experimented and made a wish: "I want to have a rice seed that is maintained!" ”

Since the last time I asked for a walkie-talkie with the technology tree and destroyed half of the energy fruit, after two years, this is the second time Xu Yue has made a wish with the technology tree.

She now knew that good steel was to be used on the blade, and that things that could take time to create on their own didn't have to be exchanged for the tech tree.

And although the third line of rice that is lacking now can be vigorously searched, their family can't wait, and no one knows if the students will be so lucky next time.

In case the third line of rice cannot be found in the entire Daqing land, then the time will be wasted.

Therefore, it doesn't matter if Xu Yue is impulsive, she just wants to give it a try.

Xu Yue looked expectantly at the projection of the technology tree floating above the research room, regardless of whether the technology tree could understand it or not, she flattered it and smiled brightly.

In an instant, ten energy fruits were extinguished in a row, and the finely broken rice seeds fell from the sky above the laboratory like rain, falling all over the ground.

Xu Yue was ecstatic, she didn't have time to complain about Koko's rude behavior, so she hurriedly got up and opened the medicine cabinet, took out the empty medicine bottles inside, and ran to the kitchen to get a broom and shovel to collect all the rice seeds spilled on the laboratory floor.

The rice seed shop is all over the ground, filled with three large glass bottles.

It's just that, looking at the five remaining red energy fruits on the technology tree, Xu Yue's heart is dripping blood.

tightened the rice seed in his arms, and then he felt a little comforted.

Laughing at the science and technology tree again, Xu Yue took the three-line rice seeds he got, walked out of the laboratory, and rushed to the experimental field, summoned the students of the Agricultural Academy, and produced a handful of rice seeds, so that they could immediately carry out hybrid experiments.

It was already cold in October, but the temperature on the test field was not too affected.

Because there is a cultivation greenhouse made of glass cover and quilt, although it is only a small corner, only occupies one-twentieth of the entire experimental field, but it does not prevent it from becoming a sacred place in the hearts of the students of the Agricultural College.

When the weather is cold, the top of the test field is covered with oilcloth, and there is a charcoal fire inside, and a thermometer made of mercury is placed in all corners of the test field, and the students always pay attention to the temperature in the test field.

Most of the fresh vegetables supplied in the winter come from the experimental fields, and only a small part comes from the silkworm rooms built by the villagers.

Of course, this is just a strategy without plastic - Xu Yue never thought that the plastic sheeting that people litter everywhere in modern times is so important.

The few leftover plastic lunch boxes, plastic buckets and other plastic products in the small kitchen of the research room are still kept by Xu Yue.

She hadn't figured out what to do with the plastics, but as a rare material in ancient times, she felt that these rare materials would always be useful one day, although, in modern times, they only deserve to be put in the scrapyard.

The whole experimental field is not large, only one acre of land, which was used by Xu Yue to cultivate cotton plants and watermelon seedlings.

This year's cotton planting area has increased significantly, and the autumn harvest has been bumper, and a lot of cotton cloth has been woven on the side of the textile mill. This durable fabric has now been fully put into the production work of the village.

There are also a lot of high-quality cotton seeds screened, which are enough to be planted in Yuyang County.

Watermelons also left a lot of seeds, but this thing is relatively fine, not as much as cotton breeding, and there are many bad seeds, Xu Yue only collected five cans of seeds, and the planting in the county is far from enough, but it can already produce steadily.

After two years, the people who can eat watermelon are not only the family gentry in Xujiazhuang and Yuyang County.

Speaking of watermelons, Xu Yue thought of Liangzhou, the westernmost part of Daqing, where the climate and soil quality are the favorite growing environment for watermelons.

If you can, bring the watermelon seeds to Liangzhou in the future, and the watermelons produced there will definitely be better than the current ones.

The students of the Faculty of Agriculture have been exposed to crossbreeding for a long time, and they have already successfully experimented with grafting and crossbreeding wheat. This is also the reason why the wheat yield in Xujiazhuang is higher than elsewhere.

In the eyes of outsiders, it is only the fine service of the wheat in Xujiazhuang, so the yield is relatively high, but in fact, the seeds planted by everyone are not the same.

My aunt's family came to ask for wheat seeds, and Xu Yue generously gave them out, and the output in the second year was really 10% more than before.

Don't underestimate this harvest, this is one-tenth of the yield, because of this extra harvest, my aunt's family originally had two meals a day, but now it has become three meals a day.

The tenants in the manor under him were also able to support one more child because of this extra tenth.

In the past few years, there have been wars everywhere, but Yuyang can be in a safe corner, and the harvest has been good for three consecutive years, and the people's lives are different from the outside.

These changes are precisely because of the little penetration of Xu Yue's family of five into Yuyang County, a little more harvest this year, and a little more wasteland next year, which has been slowly accumulated.

Wang Pingping, who went out to fight, would also deliberately avoid Yuyang County and put the main battle sites in other states and counties.

At this moment, if the people of other states and counties come to Yuyang, they will definitely be surprised by the abundance and tranquility here.

In such a good environment, the students from Xujiazhuang Agricultural College have the opportunity to experiment freely.

Now, the three-line rice seeds have been handed over to them by Xu Yue, and it is also time for them to put the experience they have accumulated over the years into practice.

Before attending Xu's class, teenagers such as Zhou Rong never knew that grain seeds could be artificially intervened to produce excellent seeds that are resistant to diseases and insects, and have high yields.

Everything they learned in the College of Agriculture changed the way of thinking of Zhou Rong and others, and their love for crops and passion for exploration are, in Xu Yue's view, better than those of modern agricultural scientists.

She was relieved to hand over rice seeds to such students.
