The county seed company is on the side of the old street, and the road is narrow and crowded, so Yunyi had to find a place to park the car and walk over.

The old street of the county seat is actually the market of the early years, the road is not wide, the storefronts are narrow, and there are snack bars, noodle restaurants, delicatessen shops, bookstores, small markets, telephone booths and so on on both sides of the street. A few years ago, when it was time for the fair, the whole street was crowded, so it was not lively! The cries of selling come and go, and many people who rush to the market do not come to buy things on purpose, but to feel this lively atmosphere, which is also another way for rural people to relax themselves when they are not working.

With the process of urbanization, the new county has wide roads, a restaurant street, a commercial street, bright storefronts, and fashionable decoration, which have gradually replaced the status of the old street.

Many young people are reluctant to go to the old street, where there are no bright lights, at a glance all the green bricks and black tiles, and occasionally you can see all wooden structure stilted buildings; The stone-paved pavement also has a lot of potholes; Despite this, the elderly still only go to the old streets to wander, where there are their memories and once left their youth.

"Hello! Do you have sorghum seeds here? Walking into the store of the Laojie Seed Company, Yun Yi asked the salesman behind the counter.

"Hello! We have a lot of sorghum seeds here, depending on which category you need! The salesperson said.

"I need a high sugar content, mainly for growing and making wine." Yunyi said.

"With high sugar content, we have 'Zhongyuan No. 1', 'Gaoshan 99', 'Hongliang No. 4' and 'Hybrid No. 33' these categories, the seed quality is good, and the germination rate is also high, all of which are above 92%, depending on which one you choose!" The salesperson introduced.

"Can you tell me more about the climates in which these varieties of seeds are suitable for planting?" Yunyi asked.

"I'm sorry! I've only been here for a long time, and I don't know much about these things, so I'll call our manager Wang to tell you, okay? The salesman said apologetically.

"Okay! Thank you! Yun Yi also said politely.

After a while, a slightly chubby middle-aged man with a teacup in his hand walked towards Yunyi, came to the front, and asked with a smile: "Little brother, do you want to know which climate and environment are suitable for planting which varieties of sorghum?" ”

"Yes! Manager Wang! Can you tell me about it? Yun Yi replied.

"Yes! Sit down first! I'll tell you about it. Manager Wang said as he put the teacup aside on the counter.

After Yunyi sat down, Manager Wang spoke:

"Most of our county is alpine area, so most of the introduced varieties are suitable for alpine growth, generally above 1,000 meters above sea level, we recommend them to choose 'Gaoshan 99' and 'Hongliang No. 4' two varieties, 600 meters to 1,000 meters above sea level, more suitable for 'Zhongyuan No. 1' and 'Hybrid No. 33'!" The salesman said carefully.

"I'm from Hegu Village, and we are only more than 400 meters above sea level, so none of the varieties you just introduced are suitable!" Yunyi explained.

"O Riverdale Village...! Which of these varieties is really not suitable. Manager Wang also thought of the special geography of Hegu Village.

"Do you have any other varieties that are suitable for us to grow there?" Yunyi asked again.

Manager Wang thought for a while and said hesitantly: "Yes, yes, yes, but we don't have many people planting here." ”

"What brand?" Yunyi asked.

"It is researched by the Provincial Academy of Agricultural Sciences, called 'Southwest Special No. 1', the seeds of this variety are adapted to a relatively wide terrain, and can be planted below 1,200 meters above sea level, but this variety was a few years ago." Manager Wang took the teacup and took a sip of tea.

"Then why are there so few people who grow this breed?" Yun Yi thought about it and then asked

"Although the seeds of this brand are very good in terms of plant length and resistance to diseases and pests, the ears are much larger than other varieties, and the sugar content is much higher; However, the disadvantage is also big, that is, the germination rate of seeds is not high, only about 75%, so the planting range is not very large. ”

After listening to Manager Wang's explanation, Yunyi thought suspiciously, although the germination rate of seeds of this variety is not high, but there are many advantages! How can there be fewer planters?

Seeing Yunyi's puzzled face, Manager Wang said again: "For other varieties of seeds, one acre of land can meet the needs of three catties of seeds at most, but the seeds of this brand need at least five catties of seeds per acre of land; You also know that the price of seeds is not low now, and the villagers want to save costs on farming; If a family plants 10 acres of land, and uses 2 catties of seeds for 1 acre of land, there will be 20 catties more for 10 acres of land, and the selling price of one catty of seeds is 120 yuan, and 20 catties is 2,400 yuan; So most people don't choose this. ”

It's not that I don't know, but I'm shocked! 2,400 yuan, that farmer is willing to use this money for waste! Even if the seed yield of this brand is high, can the high yield make up for the price difference of 2,400 yuan? Farmers are afraid to take this risk. Thinking of this, Yunyi understands why there are fewer people who choose this variety.

Although I understand, Yunyi really doesn't want to miss the advantages of so many seeds of this brand, even if it is a small-scale planting, Yunyi also wants to try planting.

"Then do you know why this seed has such a low germination rate?" Yun Yi asked unrelentingly.

Manager Wang looked at Yun Yi and saw that he had a serious expression, not like someone who had nothing to do to entertain himself, so he said again: "According to the experts who cultivated this seed from the Academy of Agricultural Sciences in the provincial city, the low germination rate of this seed is because the nutrients stored in some seeds are not enough to provide enough nutrients for the growth of seed germs, so 25% of the seeds die in the middle stage of germination due to the loss of nutrient supply. ”

When Manager Wang said this, Yunyi suddenly remembered the function of the bioactive liquid; If it is only the problem of nutrient supply during the germination period of seeds, this can be solved by using bioactive liquid, so that the germination rate of seeds can be improved.

Since the problem of seed germination rate can be solved, there should be no problem in choosing to plant this brand of sorghum; Thinking of this, a relaxed smile appeared on Yun Yi's face.

"And how many sorghum seeds of this variety do you have here?" Yun Yi asked with a smile.

"How...! Do you really want to buy this seed? Manager Wang asked with some surprise.

"Yes! Don't you sell it here anymore? Yun Yi was stunned for a moment and asked.

"No... No...! Of course we have to sell...! Only... It's just that you really want to buy it! Manager Wang couldn't understand the young man sitting in front of him.

"Of course I'm going to buy it, and there's a lot of it!" Yunyi heard that they were selling, and his heart relaxed slightly.
